Mental health disorders, such as depression or anxiety, affect the way we think, feel and behave. There are more than 200 types of mental illnesses. Symptoms of mental health disorders usually improve with treatment, which may include medication, psychotherapy, alternative therapies or brain stimulation therapy.

Behavioral health (sometimes called mental health) includes a person’s psychological, emotional and social wellbeing. It shapes the way you think, feel, behave and interact with others. Your mental state also affects how you cope with stress. It’s a vital part of your life, from infancy through adulthood.

## Symptoms and Causes

### What causes mental health disorders?

Behavioral health disorders can have many causes. They might be the result of abnormal genes. You may inherit those genes from a parent, or genes can change during your life. Chemical imbalances in your brain can also lead to mental illness.

Your risk of mental illness increases if you:

- Use alcohol or recreational drugs.
- Don’t get proper nutrition.
- Don’t have a support system of friends or family members.

## Diagnosis and Tests

### How are mental health disorders diagnosed?

It’s important to get a diagnosis from a healthcare provider who specializes in behavioral health disorders. You need an accurate diagnosis to receive the right treatment.

A healthcare provider will carefully review your symptoms to evaluate your mental health. Be sure to tell your healthcare provider:

- If there are any specific triggers that make your mental health worse.
- If your mental health problems are chronic (ongoing) or if they come and go.
- When you first noticed changes in your mental health.

There aren’t any medical tests that can diagnose mental illnesses. But your healthcare provider may perform tests, such as blood work or imaging exams, to rule out other conditions that can affect mental health.

## Management and Treatment

### How are mental health disorders treated?

Treatments for mental health disorders may include:

- Medication: Some mental illnesses respond well to medication, such as antidepressants and antipsychotics. These medicines change the chemicals in your brain, so you experience fewer symptoms. It’s very important to take medication exactly as your healthcare provider directs. Never stop taking medication for a mental illness without consulting your healthcare provider.
- Psychotherapy: Talking to a mental health professional can help you work through the challenges of an illness and manage its symptoms. Psychotherapy can be in a one-to-one setting with a healthcare provider or a group setting. Cognitive behavioral therapy (CBT) is a form of psychotherapy. It focuses on helping you change negative behaviors and thought patterns.
- Alternative therapies: Some mental illnesses, such as depression, may improve with alternative therapies. Examples include herbal remedies, massage, acupuncture, yoga and meditation. Talk to your healthcare provider before taking any herbal remedies or supplements. They may affect other medications.
- Brain stimulation therapies: Not all disorders improve with medication. If that’s the case, your healthcare provider may recommend brain stimulation therapies. These treatments change the way nerves and other cells in your brain process chemicals and respond to stimuli. Examples include electroconvulsive therapy and transcranial magnetic stimulation (TMS).
