The majority of patients with<unk>  display a limited set of physical and physiological symptoms. Rare cases in literature reveal atypical conditions, but these are often exclusive to the individual and do not suggest a widespread trend. As research continues, a larger set of symptoms can be properly assessed in the clinic. Intracranial pressure Most patients experience a series of intermittent headaches over a few weeks or sustained, powerful pressure in a matter of days. The time-frame for this pressure varies from patient to patient and fluctuate based on the stage of the tumor. Both low-grade and high-grade<unk>  can exhibit significant discomfort from headaches, although literature supports that higher-grade<unk>  affect a patient with day-to-day activities, forcing individuals to stay at home away from their jobs and family. Malignant<unk>  distorts the function of surrounding brain regions, and pressure is the primary result. Enhanced drowsiness Along with cranial pressure, patients exhibit noticeable lethargy, increasing in severity as the tumor progresses. In the first few months, morning activities are usually unaffected; over time, these effects become more pronounced, especially late at night. Lethargy can disrupt vital signs, depleting energy and desire to perform simple cognitive tasks. Frequent nausea The desire to eat normally becomes worse over time, leading to weight loss from vomiting. Nausea is seen in almost all cases of<unk> , especially in low-grade tumors. Impaired vision Vision deficit usually occurs when lesions grow in the occipital lobe of the brain, causing a blurred daze for patients, especially in sensitivity to light. Focusing upon finer objects becomes a challenge, along with edge and border detection. Driving behind the wheel is dangerous when<unk>  grows in residual tissue size, since peripheral vision can be insufficient. Horizontal nystagmus and other involuntary eye disorders can occur. Motor system imbalance and weakness Frequent reports show that adolescents and adults with grade III and IV<unk>  fall frequently before they even reach a doctor's office. Alertness is diminished when walking normally, forcing patients to exhibit awkward gait patterns to avoid imbalance. Decreased sensation Since the motor system can be impaired with severe cases, the malignant spread of<unk>  throughout the body may press against or paralyze the spinal cord, diminishing sensation in upper and lower extremities. Seizures Convulsions are observed in older patients with<unk> . Psychotic episodes Grade III and IV<unk>  have been shown gradually change the mental stability of a patient. Hallucinations impair cognition to the point where patients experience a loss of identity, although this is not commonly seen in clinic. Cognitive dysregulation Irritability, aggression, memory loss, neurological deficits, and inattentiveness on everyday tasks are the most common forms of deregulation in the mental capabilities of a patient. Verbal communication is affected, but usually not to the point where close friends can detect that the individual is cognitively impaired.
