Some vascular problems can interfere with the structural pathways in the eye that affect vision. Diabetes, retinal artery or vein occlusion, hemorrhage and vasospasm can affect vision. There needs to be, as stated before, sufficient blood, for oxygen, going between brain and eyes for vision to function properly. Vascular problems can hinder this flow. A mini-stroke can also affect vision. Other Possible Causes
Other causes of a vision blackout include: High blood pressure
Visual migraine (painful headache)
Optic neuropathy
Giant cell arteritis
Increased intracranial pressure (in the skull)
Ocular ischemia (not enough blood flow in eye from carotid artery)
So, if your vision darkens, you might be having low blood pressure issues, other vascular problems, a retinal detachment or other issues with the structure of the eyes. It is important to see a doctor if you start to feel like you might faint or if you have other issues that might indicate something as serious as a stroke, like paralysis, confusion or speech impairment.

 A blackout is a temporary loss of consciousness. In a blackout, you experience a loss of memory. There are many different causes of blackout – it might be an effect of drugs or alcohol, a problem with circulation, or a problem within the brain, such as epilepsy. It may not be serious, but it is important to see your doctor and try to establish the underlying cause. If you have a blackout, you lose consciousness temporarily. Before that, you might fall down, have blurred-vision, or be confused. Sometimes, people experience memory loss and describe this as a blackout – for example, after they have drunk a lot of alcohol or taken illicit drugs. What causes a blackout? One common cause of a blackout is fainting. Fainting occurs when your heart rate drops and your blood vessels widen, resulting in low blood pressure.

What are blackouts? Blackouts are periods of unconsciousness or memory loss. Generally, a blackout is described as a period of unconsciousness or lack of awareness when you are unable to recall what happened or what you did. Blackouts may occur as a result of brain damage, drug side effects, excessive alcohol consumption, or disorders affecting brain function, such as epilepsy. Fainting, also known as syncope, is a term used to refer to a blackout. Conditions that can cause syncope include cardiac arrhythmias (abnormal heart rate or rhythm), abnormalities of the heart muscle or valves, or a condition called postural hypotension, in which a person faints after standing up quickly from a lying position and there is insufficient blood flow to the brain at that point. A generally harmless form of blackout is known as vasovagal syncope. In this condition, there is a disruption in the balance of neurotransmitters that regulate the blood vessels and heart rate, causing a temporary decrease in blood flow to the brain. This is a common cause of fainting that may even occur as a reaction to stressful or frightening situations.

Cause Of Blackouts Fainting
More Articles : If it is a stray episode that never recurs in one's lifetime, then it may be taken lightly and forgotten. However, if one experiences the same quite often, then this should be taken as an indication towards a serious problem. In such cases, it is advisable to seek medical assistance and investigate the plausible causes related to the blackouts. One of the causes of a blackout can be problems linked to the heart such as a cardiac arrest or stroke. It may also be related to the brain. Some of the factors concerning the brain that can trigger blackouts include insufficient blood supply to the brain, epilepsy, hypoxia, cerebral hemorrhage, arrhythmia and any injury to the head. Excessive degree of physical stress and/or emotional stress can also serve as a trigger to this medical condition. Also, conditions such as dementia, Alzheimer’s disease, mental fatigue, and depression can be possible reasons for blackouts. Apart from these physical and psychological reasons, one's lifestyle could also lead to episodes of blackout. People who consume high quantity of alcohol are extremely susceptible to this condition.

This is a common cause of fainting that may even occur as a reaction to stressful or frightening situations. Typically, full consciousness promptly returns. Blackouts can also be due a recent traumatic event, in which case you may forget everything that happened right before or right after the event (anterograde amnesia). Unexplained blackouts, or blackouts that appear to be due to injury or trauma, should be evaluated by a medical professional. Blackouts may occur with a variety of other symptoms, depending on the underlying cause or disorder. Sometimes, the memories from blackouts can be recovered, while other times, they cannot.

what causes a blackout?
 what causes a blackout? Causes of Blackouts. The most common cause of a blackout is called syncope, (“sin-co-pee”). Syncope describes blacking out because of a sudden drop in blood flow to the brain. Usually syncope is so-called “Reflex Syncope”. This is the cause of fainting. The blackout occurs because blood pressure suddenly drops and the brain is temporarily starved of oxygen and glucose. Although a faint can cause accidental injury, it is not dangerous of itself, provided the patient can lie down flat. Lying flat tends to restore blood flow to the brain, especially if the head is down and the feet are raised. About half of us suffer a faint at some time during life.

It is possible that there is a tear at the retina that can cause vision loss for brief moments, because, of course, the eye might not be functioning fully if this has occurred. If a tear happens in the retina, fluid gets behind the retina and lifts it off the wall of the eye, causing a perceived darkness of vision. pinterest-pin-it
Vascular problems could be the cause of a sudden vision blackout. Courtney Rhodes, Flickr. Some rights reserved. Vascular Problem
Some vascular problems can interfere with the structural pathways in the eye that affect vision. Diabetes, retinal artery or vein occlusion, hemorrhage and vasospasm can affect vision. There needs to be, as stated before, sufficient blood, for oxygen, going between brain and eyes for vision to function properly.

 Generally, it is not cause for concern and could have a relatively simple explanation. Of course, if you are particularly concerned, or you come close to passing out, or do faint, you will want to consult a physician. It is always wise to consult a doctor in regards to these medical issues. Here we will explore the various possibilities for why you might blackout for a second. Low Blood Pressure
Some people will experience a brief blackout when they stand up. This is caused by low blood pressure, blood unable to go to the head and so it falls towards the lower body. This is called orthostatic hypotension or postural hypotension. Of course, within a moment, when blood pressure returns to normal, you regain vision and blood flows to the head. It is important to know that vision is a process that occurs between the brain and the structure of the eyes, and blood flow is necessary for this operation to occur. pinterest-pin-it
There must be sufficient blood flow between brain and eyes for you to see properly.

Summary
 In the most severe cases of alcohol intoxication, they may even fall into a coma. Due to this, it is really important to get someone emergency help if their condition is deteriorating. In cases where someone who has drunk too much needs first aid, people should: lie the person down on their side with their knees up so that they will not choke on their vomit
check that they are breathing every 15 minutes
monitor their condition and call 911 immediately if it worsens
Syncope blackouts
The American Heart Association (AHA) describe a syncope blackout as a short temporary loss of consciousness that happens when not enough blood reaches the brain. People may also refer to this type of blackout as fainting. Low blood pressure typically causes syncope blackouts because the heart cannot pump enough oxygen-rich blood to the brain. There are two main types of syncope blackouts: neurally mediated and cardiac. A neurally mediated syncope is usually benign and requires no further treatment. It could occur when a person’s blood pressure drops after they experience pain or dehydration or get up too quickly.

what causes a blackout?
 This is the cause of fainting. The blackout occurs because blood pressure suddenly drops and the brain is temporarily starved of oxygen and glucose. Although a faint can cause accidental injury, it is not dangerous of itself, provided the patient can lie down flat. Lying flat tends to restore blood flow to the brain, especially if the head is down and the feet are raised. About half of us suffer a faint at some time during life. Other Causes of Blackouts. The other important causes of a blackout are epilepsy and a psychological cause. Whereas 50% of us may faint, only about 0.7% have epilepsy, so that a blackout is much more likely to be due to a faint than an epileptic attack. Is it a fit or is it a faint? Whilst we can all usually recognise a simple faint, distinguishing between syncope and epilepsy can be very difficult.

A blackout is characterized by sudden feeling of dizziness that results in unconsciousness and fainting. The incident lasts for a short time span, ranging from seconds to minutes. On revival, the person concerned has no clue about the time lapsed during the blackout. There are various body changes that could result in a blackout. If it is a stray episode that never recurs in one's lifetime, then it may be taken lightly and forgotten. However, if one experiences the same quite often, then this should be taken as an indication towards a serious problem. In such cases, it is advisable to seek medical assistance and investigate the plausible causes related to the blackouts. One of the causes of a blackout can be problems linked to the heart such as a cardiac arrest or stroke. It may also be related to the brain.

Summary
 However, a 2016 review
Trusted Source
observes that overconsuming alcohol may lead to alcohol-induced blackouts, which can, in some cases, be due to memory loss rather than a loss of consciousness. Other possible causes of blackouts include syncope, epilepsy, and stress. Alcohol blackouts
Two different kinds
Trusted Source
of blackouts can result from drinking alcohol: en bloc and fragmentary. When a person consumes a very large volume of alcohol, an en bloc blackout may occur. If this happens, they will not remember anything that they did while they were drinking. Fragmentary blackouts tend to affect only patches of memory, so a person may be able to piece together a memory on prompting. Symptoms
If someone has drunk too much alcohol, they may have the following symptoms of alcohol intoxication: becoming confused
difficulty staying awake, or not being able to wake up
clammy skin and low body temperature
slow heart rate
vomiting and seizures
Treatment
If a person is showing symptoms of severe alcohol intoxication, it is important to call the emergency services for treatment. According to the National Institute on Alcohol Abuse and Alcoholism, a very high blood-alcohol concentration may result in a person struggling to remain conscious.

A blackout is a temporary loss of consciousness. It is called a blackout because your eyesight starts dimming and you can see only blackness as you faint. The reasons for blackout can be anything. It can be something as simple as an acid attack and also as serious as a blood clot in the brain. It is however important to establish the medical causes for a blackout. The causes of fainting vary from person to person and depend on the situation he/she is in.

 The most common cause of a complete or partial blackout is alcohol. When you drink while taking other drugs, a blackout is even more likely. Frequent alcohol-related blackouts might be a sign of problem drinking. If you or someone you know has blackouts that involve loss of memory or consciousness and you don’t know why, see a doctor right away. Blackouts can be a sign of a serious medical condition. How Does Alcohol Cause Blackouts? If you usually stop after a drink or two, then you’ve probably never had an alcohol-related blackout. They usually happen when people drink too much too fast. Consuming excessive alcohol can lead to gaps in memory. Those gaps form because the alcohol prevents short-term memories from becoming long-term memories.

Not to be confused with Redoubt. For the video game, see Redout (video game). A redout occurs when the body experiences a negative g-force sufficient to cause a blood flow from the lower parts of the body to the head. It is the inverse effect of a greyout, where blood flows away from the head to the lower parts of the body. Usually, a redout will only ever be experienced by pilots, as planes are the most common devices that allow such negative g-forces to be exerted. Redouts are potentially dangerous and can cause retinal damage and hemorrhagic stroke. The predominant theory on the red appearing in the visual field is not due to the actual blood flow to the eye. It is most likely due to the blood laden lower eyelid coming into the visual field due to the pull of negative-Gs. See also

 So, you need to understand the effects of your body when you consume alcohol. So, your risk of fainting comes down to the amount of alcohol in the drink you consume and how your body reacts to it. Traumatic Incidents Causing Blackouts
When you suffer some unexpected traumatic events, which affect your head, then you can suffer from blackouts. The trauma to the head can cause damage to the brain, leading to the condition. The events or diseases causing such complications are: The complication caused by brain surgery
Electroshock therapy
Mild head injury
Concussion
Inoculations and injection
Traumatic emotional event
Substance-Related Issues Of Blackouts
Fainting can occur due to the use of recreational drugs or other substances like alcohol. So, you can suffer from the issue due to the following: Alcohol intoxication
Recreational drug use
Exposure to poisons like pesticides or cleaning chemicals
Side effects due to medications used for cancer treatment or seizures
Anesthesia agents
Diseases Causing Blackouts

Summary
 Low blood pressure typically causes syncope blackouts because the heart cannot pump enough oxygen-rich blood to the brain. There are two main types of syncope blackouts: neurally mediated and cardiac. A neurally mediated syncope is usually benign and requires no further treatment. It could occur when a person’s blood pressure drops after they experience pain or dehydration or get up too quickly. This type of syncope tends to occur more in children and young adults. A cardiac syncope is more serious as it could signal an underlying problem with the heart. Tachycardia, bradycardia, or other types of hypotension could cause a cardiac syncope. If a person does not get treatment, they are at risk of complications or even sudden cardiac death. Treatment
A doctor may prescribe fludrocortisone to reduce blackouts

 Typically, full consciousness promptly returns. Blackouts can also be due a recent traumatic event, in which case you may forget everything that happened right before or right after the event (anterograde amnesia). Unexplained blackouts, or blackouts that appear to be due to injury or trauma, should be evaluated by a medical professional. Blackouts may occur with a variety of other symptoms, depending on the underlying cause or disorder. Sometimes, the memories from blackouts can be recovered, while other times, they cannot. It is also possible that blackouts can lead to problems forming new memories. Seek immediate medical care (call 911) for memory loss that occurs with head injury or trauma, high fever (higher than 101 degrees Fahrenheit), uncontrolled or heavy bleeding, loss of consciousness, or seizure. Seek immediate medical care (call 911) if you believe a person may have alcohol poisoning or may be suffering from a drug overdose. If your blackouts recur or cause you concern, seek prompt medical care. What other symptoms might occur with blackouts?

 An orbital fracture involving one of the five delicate bones around the eye may trap an eye muscle or soft tissues. A fracture could also damage the optic nerve and permanently damage eyesight. If so, emergency surgery may be required to correct the condition. What Causes a Black Eye? Most black eyes are the result of blunt trauma that causes bleeding beneath the thin eyelid skin, producing the characteristic black and blue discoloration. A fracture deep inside the skull can also blacken both eyes in what they call "raccoon eyes," even though the eye area itself was not injured. People with sinusitis from allergies sometimes get "allergic shiners" -- darkening under the eyes caused by inflamed and engorged blood vessels -- but this is not the same thing as a black eye, which is caused by an injury.

Blackouts occur when your brain experiences damage due to using recreational drugs or excess alcohol consumption. Syncope
Abnormal heart conditions can lead to fainting. It includes an abnormal heart rate or rhythm (cardiac arrhythmias). The structural abnormalities of heart valves or muscles. You can also faint when you suffer from a condition called postural hypotension. It occurs when you suffer from blackouts when you stand abruptly from a sitting or lying position. It occurs due to insufficient blood flow to the brain. Traumatic Events
Any recent traumatic event leading to memory loss like anterograde amnesia can lead to fainting. In such cases, you tend to forget everything happened before or right after the traumatic event.

 It is called a blackout because your eyesight starts dimming and you can see only blackness as you faint. The reasons for blackout can be anything. It can be something as simple as an acid attack and also as serious as a blood clot in the brain. It is however important to establish the medical causes for a blackout. The causes of fainting vary from person to person and depend on the situation he/she is in. For example, blackouts during pregnancy are very common. But if you are not pregnant or sick, a blackout can be a cause of worry. Sometimes, losing consciousness might be treated as a symptom of some health problem.

The following are measures you can take to help prevent blacking out while drinking:
 Basically, drinking alcohol creates an "overload" in the brain and they blackout as a result. That means a blackout is a form of amnesia. Alcohol plus other substances
While alcohol alone is the primary culprit in causing blackouts, drinking in combination with drug use increases the chances of a blackout. Benzodiazepine compounds such as Valium and Rohypnol can both cause memory loss, and combined with alcohol the chance of a blackout is extremely high. Likewise, combining alcohol with THC causes greater memory loss, so using marijuana while drinking may cause you to blackout. Causes of blackouts
While blackouts are most commonly linked to alcohol consumption (heavy drinking on an empty stomach or chugging), there are other causes that may come into play, with the most common cause of non-alcoholic blackouts being a drop in blood pressure. Here are other causes of blackouts: Low blood pressure
Epilepsy
Low blood sugar
Psychogenic seizures
Lack of oxygen
Reactions to medications
Although you may associate blackouts with full-blown alcoholics in fact they are more common with social drinkers and binge drinkers. The National Institutes of Health states "If recreational drugs were tools, alcohol would be a sledgehammer" because of the range of functions it can impair. Blackouts have long been recognized as a primary indicator of alcoholism, as E.M. Jellinek stated in 1946.

What causes blackouts and how can they be treated? What causes blackouts and how can they be treated? A: Sudden onset of unconsciousness in the sixth decade of life may be caused by many abnormalities. Broadly speaking, these may be related either to the brain or the heart. In this case, the patient has undergone the necessary investigations for the brain and its blood supply. If these are mostly normal, one should also consider the possibility of certain heart related diseases that can make a person unconscious suddenly. These may be related to abnormal rhythms of the heart, pauses in the heart's rhythm, or simply drop in blood pressure. A 2D Echocardiography test is also advisable to rule out clots in the heart that may be thrown into the brain. As the Holter monitoring (recording the heart rhythm and blood pressure over 24 hours) is also normal, we have to consider rare causes. As mentioned in the past history, the patient also had sarcoidosis in past .

Summary
 This type of syncope tends to occur more in children and young adults. A cardiac syncope is more serious as it could signal an underlying problem with the heart. Tachycardia, bradycardia, or other types of hypotension could cause a cardiac syncope. If a person does not get treatment, they are at risk of complications or even sudden cardiac death. Treatment
A doctor may prescribe fludrocortisone to reduce blackouts
Trusted Source
in people who experience neurally mediated syncope. If anyone feels as though they are about to faint, they should sit or lie down so that they do not injure themselves if they fall unconscious. Diagnosis
If a person is experiencing syncope blackouts, a doctor may request an electrocardiogram (EKG) to see whether there are any underlying problems with the heart. They may also order a tilt test. During this test, a person lies down on a board that moves to change their position while healthcare professionals measure their blood pressure and heart rate. Epilepsy blackouts
A disturbance of neuronal activity in the brain can cause an epileptic episode.

 Even with cues, you’re unlikely to remember what happened during this time. The nature of blackouts makes it difficult for researchers to examine the correlation between memory recall and blackout type. Blackouts are often associated with alcohol consumption. For many people, drinking too much alcohol too quickly, or on an empty stomach, can cause a blackout. A blackout can also be caused by: epileptic seizures
fainting
low blood pressure
psychogenic seizures
low blood sugar
certain medications
oxygen restriction
A 2006 study

found that temporary memory loss caused by a fall in blood pressure (syncope) is a more likely cause of nonalcoholic-induced blackouts. What happens to the body during a blackout? Alcohol impairs your ability to walk, speak, react, and remember events. It also lowers inhibition, hinders impulse control, and affects decision-making. The reward pathway in the brain regulates these activities.

Summary
 If medication proves ineffective, doctors may recommend surgery. Some children may be unable to take medication due to the side effects. In these cases, they may benefit from special diets. Diagnosis
If a doctor suspects that a person has epilepsy, they may request an MRI or CT scan. These imaging techniques help the doctor examine brain activity and rule out other neurological conditions. Learn more about epilepsy here. Can stress cause blackouts? If a person experiences blackouts as a result of stress, this is known as a psychogenic blackout. While these blackouts are similar to syncope and epileptic blackouts, the causes are different. Experts believe that when people are experiencing a threatening feeling, thought, or memory, it can overwhelm them so much that it induces a seizure.

How to prevent blackouts
 A person who has blacked out or overdosed on alcohol could throw up while sleeping due to the loss of reflex control. This could cause them to choke and suffocate on their vomit. A blackout also makes you more susceptible to injury, such as from a fall or car crash. Taking sedatives while also consuming alcohol can increase the likelihood that you’ll black out. That’s because benzodiazepines like alprazolam (Xanax), and opioids like oxycodone (OxyContin), activate the GABA neurotransmitter. This causes your body to slow down and become more relaxed. Like alcohol, sedatives can impair your ability to think and make memories. THC, the psychoactive compound found in marijuana, may also increase blackouts when combined with alcohol.

 The vasovagal center in the brain which is responsible for contraction of blood vessels in the legs discharges signal to dilate and thus the blood is pooled. This happens when a person stands up suddenly from sitting position. There are several non cardiac causes such as dehydration resulting from severe diarrhea, overheating, anemia etc. Due to sudden fall in blood pressure, the blood circulation in brain is hampered for a second and that results in blackouts. It is a momentary episode and a person regains his vision quickly. Blackouts may also occur due to cardiac causes. Slow heart beat, irregularity in heart rhythm, rapid pulse and valvular problems all can cause sudden blackouts when you stand from a lying or sitting position. How To Prevent Blacking Out When Standing Up? Blackout when standing up is not a serious condition and it can be prevented by following few preventive steps. Instead of getting out of bed suddenly, sit for a while on the bed and then stand up.

Summary
 During these episodes, people may experience a seizure. Their muscles may contract, and they could lose consciousness. However, just because a person has epilepsy, it does not necessarily mean that they will blackout when they have a seizure. The disorder is a spectrum, and it covers many other symptoms. Symptoms
Many different symptoms could accompany epileptic blackouts, depending on the type of seizure that a person is experiencing. According to the University of California, San Francisco, one particular type of epileptic seizure that causes blackouts is a tonic-clonic seizure — also known as a grand-mal seizure. During this epileptic episode, people lose consciousness, and the body goes stiff (tonic phase). The muscles then contract, which may result in the jaw clamping shut (clonic phase). Treatment
The National Institute of Neurological Disorders and Stroke estimate that 70% of people with epilepsy can control their symptoms by taking medication or undergoing surgery. Since the Food and Drug Administration (FDA) approved them in 2019, doctors have been able to prescribe cenobamate tablets for adults who experience blackouts during seizures.

Summary
 If anyone feels as though they are about to faint, they should sit or lie down so that they do not injure themselves if they fall unconscious. Diagnosis
If a person is experiencing syncope blackouts, a doctor may request an electrocardiogram (EKG) to see whether there are any underlying problems with the heart. They may also order a tilt test. During this test, a person lies down on a board that moves to change their position while healthcare professionals measure their blood pressure and heart rate. Epilepsy blackouts
A disturbance of neuronal activity in the brain can cause an epileptic episode. During these episodes, people may experience a seizure. Their muscles may contract, and they could lose consciousness. However, just because a person has epilepsy, it does not necessarily mean that they will blackout when they have a seizure. The disorder is a spectrum, and it covers many other symptoms. Symptoms

 When you faint, you tend to panic as you never know what causes the condition. But, not all conditions are serious. You can experience any of the following, which varies in its severity. Vasovagal Syncope
Verywellhealth.com
It is the harmless form of fainting. Vasovagal syncope occurs due to the disruptions in the normal balance of neurotransmitters in your body. This balance regulates your heart rate and blood vessels. So, the imbalance can lead to a temporary decrease in the blood flow to your brain. It is the most common cause of fainting in people. You can face the problem when you go through a stressful or dangerous condition. But, you can recover without any complication promptly.

Causes of black eye
A black eye is the appearance of bruising around the eyes. It’s usually the result of trauma to the head or face, which causes bleeding beneath the skin. When the small blood vessels, or capillaries, beneath the skin break, blood leaks into the surrounding tissue. This is what causes the discoloration or bruising. Most black eyes aren’t serious, but they can sometimes be an indicator of a medical emergency such as a skull fracture. Black eye is also referred to as eye bruises and bruising around the eyes. Black eyes can appear after some surgical procedures, such as nose surgery or a facelift. A black eye may occur when blood, originating in the forehead or nose, settles by gravity under the eye. “ Raccoon eyes ” refers to blood that settles under the eyes and is associated with a fracture in the base of the skull.

 Blackout is felt when you suddenly stand up because large proportion of blood gets pooled in the lower leg. It is a vasovagal reaction. This leads to sudden fall in blood pressure. The other name for such episode is postural hypo-tension. It has nothing to do with the blood vessels of the leg, but something to do with the nerves. The vasovagal center in the brain which is responsible for contraction of blood vessels in the legs discharges signal to dilate and thus the blood is pooled. This happens when a person stands up suddenly from sitting position. There are several non cardiac causes such as dehydration resulting from severe diarrhea, overheating, anemia etc. Due to sudden fall in blood pressure, the blood circulation in brain is hampered for a second and that results in blackouts. It is a momentary episode and a person regains his vision quickly.

what causes a blackout?
 Other Causes of Blackouts. The other important causes of a blackout are epilepsy and a psychological cause. Whereas 50% of us may faint, only about 0.7% have epilepsy, so that a blackout is much more likely to be due to a faint than an epileptic attack. Is it a fit or is it a faint? Whilst we can all usually recognise a simple faint, distinguishing between syncope and epilepsy can be very difficult. A simple faint usually has a warning period when the patient feels hot, sweaty and sickly, and they go pale. They often then collapse rather gracefully, and once down on the ground, recover quickly. Our concept of a “seizure” is when a patient collapses abruptly with a blackout, there are abnormal movements of the face, arms and legs, there may be incontinence and tongue-biting, and they take longer to recover. What is not widely appreciated is that such a “seizure” can occur frequently with syncope as well as with epilepsy. However, in syncope the mechanism is lack of blood flow to the brain, and in epilepsy, despite normal blood flow, the brain cells have a fit.

A greyout is a transient loss of vision characterized by a perceived dimming of light and color, sometimes accompanied by a loss of peripheral vision. It is a precursor to fainting or a blackout and is caused by hypoxia (low brain oxygen level), often due to a loss of blood pressure . Greyouts have a variety of possible causes: Shock, such as hypovolemia, even in mild form such as when drawing blood. Suddenly standing up (see orthostatic hypotension ), especially if sick, hungover, or suffering from low blood pressure. Fatigue
Paradoxically, hyperventilation: self-induced hypocapnia such as in the fainting game or in shallow water blackout. Overexertion
Panic attack
Usually recovery is rapid and a greyout can be readily reversed by lying down.

heart disease
problems with the blood vessels in the brain
some mental illnesses
a seizure
low blood sugar
illicit drugs
some medicines

What causes blackouts and how can they be treated? If these are mostly normal, one should also consider the possibility of certain heart related diseases that can make a person unconscious suddenly. These may be related to abnormal rhythms of the heart, pauses in the heart's rhythm, or simply drop in blood pressure. A 2D Echocardiography test is also advisable to rule out clots in the heart that may be thrown into the brain. As the Holter monitoring (recording the heart rhythm and blood pressure over 24 hours) is also normal, we have to consider rare causes. As mentioned in the past history, the patient also had sarcoidosis in past . Some patients with this disease may develop affection of the brain directly or by blocking the small blood vessels in the brain. It is advisable to do further specialised tests like cerebral DSA (Digital Substraction Angiography) and contrast MRI Brain to exclude these possibilities. While investigating further, it is advisable that the patient takes medicines to cover for both the possibilities: abnormal electrical brain activity causing unconsciousness or blockages in the blood supply to the brain. Hence I would recommend that the patient starts with Tablet Aspirin 75 mgs once daily after dinner, and a good anticonvulsant.

Summary
 If this happens, they will not remember anything that they did while they were drinking. Fragmentary blackouts tend to affect only patches of memory, so a person may be able to piece together a memory on prompting. Symptoms
If someone has drunk too much alcohol, they may have the following symptoms of alcohol intoxication: becoming confused
difficulty staying awake, or not being able to wake up
clammy skin and low body temperature
slow heart rate
vomiting and seizures
Treatment
If a person is showing symptoms of severe alcohol intoxication, it is important to call the emergency services for treatment. According to the National Institute on Alcohol Abuse and Alcoholism, a very high blood-alcohol concentration may result in a person struggling to remain conscious. In the most severe cases of alcohol intoxication, they may even fall into a coma. Due to this, it is really important to get someone emergency help if their condition is deteriorating. In cases where someone who has drunk too much needs first aid, people should: lie the person down on their side with their knees up so that they will not choke on their vomit
check that they are breathing every 15 minutes
monitor their condition and call 911 immediately if it worsens
Syncope blackouts
The American Heart Association (AHA) describe a syncope blackout as a short temporary loss of consciousness that happens when not enough blood reaches the brain. People may also refer to this type of blackout as fainting.

 A psychogenic blackout often lasts much longer than reflex syncope. What causes psychogenic blackouts? The medical profession is gradually beginning to recognise and understand what causes blackouts. It is accepted it is not caused by physical problems and it happens for different reasons in different people. It is likely a psychogenic blackout can happen when there is a temporary problem with the way the brain is working. The brain may become “overloaded” and “shut down” for a short while when faced with some kind of threatening feeling, situation, thought or memory. Although it is thought stress plays an important part in these attacks, people can pass out at times when they do not feel particularly stressed. Sometimes the first attacks are related to an upsetting or frightening experience, or some other great loss or change. These experiences may be recent or in the past. Sometimes it is not clear why attacks have started, or they seem to have started just as some life stress was getting better.

 While the individual may appear to be functioning normally, decision-making, judgment, and impulse control are impaired during a blackout. The individual may experience difficulty walking, talking, standing, and seeing. 1
What Causes Blackouts? Blackouts are caused by drinking too much alcohol too quickly. Alcohol interferes with the brain’s ability to form new long-term memories. As more alcohol is consumed and the blood alcohol level rises, the degree of memory loss increases. It is believed that blackout occurs when the blood alcohol level reaches 14% or more. However, there is no set number of drinks that results in a blackout. It depends on the amount of alcohol in each drink and how alcohol affects the individual. Other factors that come into play include weight, gender, the type of alcohol, and how quickly it is consumed.

How to prevent blackouts
 What causes a blackout? There are two types of blackouts: partial and complete. If you experience a partial blackout, visual or verbal cues may help you remember forgotten events. If you have a complete blackout, memory loss is permanent. Even with cues, you’re unlikely to remember what happened during this time. The nature of blackouts makes it difficult for researchers to examine the correlation between memory recall and blackout type. Blackouts are often associated with alcohol consumption. For many people, drinking too much alcohol too quickly, or on an empty stomach, can cause a blackout. A blackout can also be caused by:

Summary
 Some symptoms of psychogenic blackouts include: fainting and falling
jerking movements of the arms and legs
losing control of the bladder and bowel
going “blank” and feeling out of touch with the surroundings
not being able to remember the blackout
Treatment
According to the Epilepsy Society, people who experience psychogenic blackouts may benefit from cognitive behavioral therapy (CBT). CBT helps people identify stressful triggers and put techniques in place to cope when they feel overwhelmed. Diagnosis
If a person believes that they are experiencing psychogenic blackouts, a doctor may refer them to a neurologist, who may be able to diagnose psychogenic blackouts by ruling out other causes. Can medication cause blackouts? According to one 2015 study
Trusted Source
, vasodilatory medications and diuretics could result in syncope blackouts. Another 2015 study

suggests that overconsuming sedatives could cause memory loss. In one case study, the excessive use of alprazolam (Xanax) led a 50-year-old woman to experience memory loss blackouts. However, more research is necessary to support these findings. When to see a doctor
A person should speak to a doctor if they believe that they are experiencing symptoms of syncope, epileptic blackouts, or blackouts that are the result of medication.

The following are measures you can take to help prevent blacking out while drinking:
 When you drink alcohol too fast it causes a wall between the two memories and short-circuits the short-term memories so they cannot form. Your memories are formed by receptors in the brain, and alcohol interferes with the receptors and prevents the new memories from forming. The degree of interference determines whether you have a brownout, or fragmented memories, or a blackout where all memories are missing. While not fully understood, research suggests that some people are more prone to blackouts because their brains respond differently to alcohol consumption. They show decreased activity in the parts of the brain that turn experiences into memories and also in the areas that govern attention and cognitive function. Basically, drinking alcohol creates an "overload" in the brain and they blackout as a result. That means a blackout is a form of amnesia. Alcohol plus other substances
While alcohol alone is the primary culprit in causing blackouts, drinking in combination with drug use increases the chances of a blackout. Benzodiazepine compounds such as Valium and Rohypnol can both cause memory loss, and combined with alcohol the chance of a blackout is extremely high. Likewise, combining alcohol with THC causes greater memory loss, so using marijuana while drinking may cause you to blackout.

 A ''black eye '' is a bruise to the eyelid skin caused by blunt trauma to the eye region. Like many bruises, a "shiner" is usually nothing to worry about and will disappear in 1-2 weeks. In some cases, however, a black eye is a warning sign of more serious injury to the eye or to the skull. Any damage to the eyeball that causes it to become red and swollen must be promptly evaluated by a doctor or an eye specialist. Blunt force eye injuries, as happens in fighting, competitive sports, and ordinary accidents, could involve an unsuspected detached retina, internal bleeding, or other serious problems. An orbital fracture involving one of the five delicate bones around the eye may trap an eye muscle or soft tissues. A fracture could also damage the optic nerve and permanently damage eyesight. If so, emergency surgery may be required to correct the condition. What Causes a Black Eye? Most black eyes are the result of blunt trauma that causes bleeding beneath the thin eyelid skin, producing the characteristic black and blue discoloration.

 Causes of blackouts
While blackouts are most commonly linked to alcohol consumption (heavy drinking on an empty stomach or chugging), there are other causes that may come into play, with the most common cause of non-alcoholic blackouts being a drop in blood pressure. Here are other causes of blackouts: Low blood pressure
Epilepsy
Low blood sugar
Psychogenic seizures
Lack of oxygen
Reactions to medications
Although you may associate blackouts with full-blown alcoholics in fact they are more common with social drinkers and binge drinkers. The National Institutes of Health states "If recreational drugs were tools, alcohol would be a sledgehammer" because of the range of functions it can impair. Blackouts have long been recognized as a primary indicator of alcoholism, as E.M. Jellinek stated in 1946. Because of the wide-ranging dangers that can occur during a blackout, if you find you're prone to having them you should consider abstaining. Much like an allergy to certain foods, your body is telling you in no uncertain terms that alcohol may be deadly. If you have experienced one or more blackouts you may find they suddenly occur after only one or two drinks, and by then it may be too late. Memory and blackouts
The memory impairments of a blackout are permanent. While you won't experience long-term memory loss, memory of the events that occurred during the blackout will never return.

 It might have developed because the skin overlying a black eye sometimes can appear shiny. Another theory is that a black eye sometimes appears as though a person has applied a smudge of "black" used to shine shoes around his or her eye.) Because the facial skin around the eye socket is relatively thin and transparent, even a slight pooling of blood can result in a very noticeable discoloration. Also, since the tissue in this area is relatively loose, fluid leaking from blood vessels easily accumulates around the eye, resulting in a puffy black eye. What causes black eyes? Black eyes are usually the result of an accident in which an object strikes the area surrounding the eyes. These accidents occur for countless reasons, from playing sports to simply walking into something. Other common causes include cosmetic eye surgery, sinus infections and nasal surgery. Even dental work and tooth infections can sometimes cause a black eye. More serious causes of black eyes include cellulitis (a serious infection around the eyes) and skull fracture, which tends to result in two shiners that are sometimes described as "raccoon eyes."

Summary
 According to the University of California, San Francisco, one particular type of epileptic seizure that causes blackouts is a tonic-clonic seizure — also known as a grand-mal seizure. During this epileptic episode, people lose consciousness, and the body goes stiff (tonic phase). The muscles then contract, which may result in the jaw clamping shut (clonic phase). Treatment
The National Institute of Neurological Disorders and Stroke estimate that 70% of people with epilepsy can control their symptoms by taking medication or undergoing surgery. Since the Food and Drug Administration (FDA) approved them in 2019, doctors have been able to prescribe cenobamate tablets for adults who experience blackouts during seizures. If medication proves ineffective, doctors may recommend surgery. Some children may be unable to take medication due to the side effects. In these cases, they may benefit from special diets. Diagnosis
If a doctor suspects that a person has epilepsy, they may request an MRI or CT scan. These imaging techniques help the doctor examine brain activity and rule out other neurological conditions.

4 Things You Need To Know About Alcohol-Induced Blackouts 3) What Causes Someone to Blackout? Though it is still unclear why some people experience blackouts and some don’t, despite consuming the same amount of alcohol, the recipe for a blackout is fairly straightforward. Dr. White explains, “Alcohol is more likely to cause a blackout when it gets into your body, and therefore your brain, fast. It catches the memory circuits off guard and shuts them down. Doing shots or chugging beer, and doing it on an empty stomach, gets the alcohol into your bloodstream quickly.” The rapid rise in Blood Alcohol Concentration (BAC) is likely to cause a blackout. This explains why blackouts are very common among college students, as they are more inexperienced drinkers and tend to drink faster, not aware of how much alcohol they are actually consuming. “ Studies tell us at least half of young people who drink experience a blackout before they graduate college,” says Dr. White. Women are also at a particularly higher risk for blackouts. They tend to weigh less than men, and alcohol is not as easily diluted in their bodies due to a lower water content, causing higher levels of alcohol in the brain.

What causes blackouts and how can they be treated?
What causes blackouts and how can they be treated? Some patients with this disease may develop affection of the brain directly or by blocking the small blood vessels in the brain. It is advisable to do further specialised tests like cerebral DSA (Digital Substraction Angiography) and contrast MRI Brain to exclude these possibilities. While investigating further, it is advisable that the patient takes medicines to cover for both the possibilities: abnormal electrical brain activity causing unconsciousness or blockages in the blood supply to the brain. Hence I would recommend that the patient starts with Tablet Aspirin 75 mgs once daily after dinner, and a good anticonvulsant. If he does not tolerate levetiracetam (Levipil), some other good choices can be sodium valproate (Encorate / Valparin) or carbamazepine (Tegretol / Zen / Mazetol). Please consult a qualified Neurologist for deciding about the right choice.

 Any trauma to the eye or surrounding area can cause damage to the blood vessels, causing them to leak and resulting in the formation of a bruise. The skin around the eye is generally thinner than on other parts of the body, so usually, it doesn’t take much to get bruised there. Also, the skin tissue around the eye is looser, which means fluid leaking from blood vessels accumulates easier there. A black eye is also referred to as a “shiner.” The term is believed to have been coined back in 1904 because the appearance of a black eye seemed to have a shine to it. Alternative explanation suggests it’s called a shiner because it appears as if a person applied black shoe shine around the eye. Black Eye Causes
A black eye is commonly caused by trauma to the eye. If something strikes the eye, it can result in damaged blood vessels. Accidents that can lead to a black eye include contact sports, falling, bumping into something, or being directly hit in the eye. Even medical procedures can result in black eyes, including cosmetic eye surgery, sinus surgery, or dental work.

Hi. There are many conditions which would lead to "blackouts" or fainting spells or what is medically referred to as syncope, not just tumors. Causes of blackouts include heart conditions such as arrhythmia and heart attack, diabetes, hypoglycemia, seizures,emotional stress, etc. Prevention of blackouts would be accomplished by treating the underlying condition which is causing the symptoms. Treatment of brain tumors would depend on the type, size, location and aggressiveness of the tumor. Hope this answers your query. Next Question

 Black eyes are usually the result of an accident in which an object strikes the area surrounding the eyes. These accidents occur for countless reasons, from playing sports to simply walking into something. Other common causes include cosmetic eye surgery, sinus infections and nasal surgery. Even dental work and tooth infections can sometimes cause a black eye. More serious causes of black eyes include cellulitis (a serious infection around the eyes) and skull fracture, which tends to result in two shiners that are sometimes described as "raccoon eyes." A serious condition that can accompany a black eye is bleeding inside the anterior  part of the eye (between the back side of the cornea and the front of the iris ). This is called hyphema (hy-FEE-muh). A hyphema is a medical emergency, as it can lead to increased eye pressure and vision loss from glaucoma if left untreated. Another condition often accompanying a black eye is a bright red appearance to the "white" of the eye (sclera). This is called a subconjunctival hemorrhage and (though it looks pretty scary) it usually is not serious and typically resolves without treatment within a couple weeks.

Black eye
 And a orbital blowout fracture is when one of the bones that surround the eye becomes fractured. Both injuries usually happen together as the result of a severe blow to the face. Symptoms of hyphemas and orbital blowout fractures include: eye pain – this is often worse when moving the eyes
blurred vision
doubled vision
swelling and bruising around the eye
It's common to develop a black eye after this type of injury (caused by blood pooling inside the eye). The black eye can persist for several weeks. A corneal laceration
A corneal laceration is a cut to the front section of the eye. Symptoms include: eye pain, which can be particularly painful
tearing
blurred vision
When to seek medical advice
Speak to your doctor immediately if you have any of the following: persistent eye pain
foreign bodies that can't be washed out
blurred and decreased vision
flashing lights, spots or shapes made up of shadows in your field of vision
redness in the eye, particularly around your iris (the coloured part of the eye that controls the amount of light that enters)
pain when exposed to bright light
an eye injury as a result of an object hitting your eye at high speed
Go to your nearest accident and emergency (A&E) department if your eyes have been exposed to chemicals (wash them out with water for 20 minutes first) or you have cut the front of your eye. Blood supplies oxygen to the body and removes carbon dioxide.

 A rapid increase in blood alcohol concentration (BAC) is most consistently associated with the likelihood of a blackout. However, not all subjects experience blackouts which implies that genetic factors play a role in determining central nervous system (CNS) vulnerability to the effects of alcohol. The former may predispose an individual to alcoholism, as altered memory function during intoxication may affect an individual’s alcohol expectancy, one may perceive positive aspects of intoxication while unintentionally ignoring the negative aspects. Causes
Blackouts are commonly associated with the consumption of large amounts of alcohol; however, surveys of drinkers experiencing blackouts have indicated that they are not directly related to the amount of alcohol consumed. Respondents reported they frequently recalled having "drunk as much or more without memory loss," compared to instances of blacking out. Subsequent research has indicated that blackouts are most likely caused by a rapid increase in a person's blood-alcohol concentration. One study, in particular, resulted in subjects being stratified easily into two groups, those who consumed alcohol very quickly, and blacked out, and those who did not black out by drinking alcohol slowly, despite being extremely intoxicated by the end of the study. In another study hospital file data showed, that of 67 participants who abused alcohol, 39 had reported a blackout. The presence or absence of blackouts was cross-tabulated against various measures of alcohol problem severity.

Hello,
Black outs on laughing hard is due to hypoxia of the brain i.e when the brain does not get proper supply of oxygen. It may be due to cardiovascular causes, neurological causes or vasovagal attacks. Patients with cerebrovascular disease have partial or complete blockages in the arteries that supply the brain with blood. These blockages can cause a temporary loss of blood flow (called transient ischemic attack, or TIA for short), or permanent loss of blood flow (called stroke; also called cerebrovascular accident).This can lead to impaired blood flow through these arteries and so dizziness particularly on exaertional activity like laughing. Moreover, drugs like antihypertensivs, nitroglycerin and diuretics can lead to dizziness as their side effects. Other conditions are diabetes and vertebrobasilar insufficiency. I advise you to consult a cardiologist and neurologist and discuss these possibilities with them. Hope it helps. Take care and pls do keep me posted in case of any additional queries and how you are doing.

Black Eye
Medically reviewed by Drugs.com. Last updated on Aug 31, 2020. Health Guide
What is a Black Eye? A black eye, sometimes called a "shiner," is a bruise around the eye. When an object strikes the eye, the force of the impact breaks delicate blood vessels in the eyelids and surrounding tissues. Blood collects under the skin, and causes black or blue discoloration in the eyelids and around the eye socket. Because the skin around the eye is relatively thin and transparent compared to skin in other parts of the body, the black and blue color of a bruised eye may seem darker and more intense than bruises elsewhere. Although many people associate black eyes with fighting and violence, only about 15% of eye injuries are caused by violent assaults. Most black eyes happen by accident — during contact sports, at work, in a car crash or during home repair.

 When people drink this much, blood alcohol levels may reach or exceed 0.08 or higher, which is the legal limit to be considered impaired. The more quickly alcohol enters the bloodstream, the more likely a person is to black out. Alcohol-related blackouts can happen to anyone, but certain things like the following can make them more likely: Taking prescription medications or other drugs while drinking
Drinking on an empty stomach
Drinking too fast
Being younger aged, which makes a person more likely to binge drink and to overestimate how much he can handle
Lower weight
Is It Dangerous to Black Out? Alcohol-related blackouts generally don’t cause more widespread loss of memory. But blackouts can be very dangerous. That’s because people who’ve blacked out don’t know what they are doing and may do things they otherwise wouldn’t. The consequences may be embarrassing, or they could be dangerous. For example, you could become a victim of a violent crime. Blackouts may even be life-threatening.
