What Is Psychosis?
Psychosis is a symptom of psychiatric disorders that affects the way the brain perceives reality. Patients who have psychosis may be unable to distinguish reality from psychotic hallucinations (seeing or hearing things that are not there) or delusions (false beliefs).
Psychiatric disorders that may include psychosis as a symptom include:

- Drug-induced psychosis, which is a result of using or withdrawing from alcohol, marijuana, amphetamines, LSD, ecstasy, or mushrooms
- Brief reactive psychosis (rare) caused by a stressful event (symptoms are usually short-lived)
- Certain illnesses such as Alzheimer's disease
- Certain medications may induce psychosis.

How Do Medical Professionals Diagnose Psychosis?
Psychosis is typically diagnosed after an evaluation by a psychiatrist, psychologist, social worker, or another type of mental health counselor. This involves the medical professional asking questions about symptoms and signs.
In some cases, medical professionals may order the following tests to determine if there is an underlying medical cause for the psychotic symptoms and signs:
- Urine test for drugs of abuse
- Liver function tests may reveal alcohol abuse
- Complete blood count (CBC) to check for systemic infection or chronic disease
- Blood tests for syphilis or HIV
- Computerized tomography (CT) scan or magnetic resonance imaging (MRI) of the brain to check for tumors or brain lesions
- Thyroid tests to rule our thyroid disorders
- Electrolyte and calcium levels to rule out metabolic disturbance
- Electroencephalography (EEG) to check for epilepsy

Treatment for symptoms of psychosis usually includes a combination of medications and psychological therapies.
Medications used to treat psychosis include
- antidepressants, and
- anti-anxiety drugs.
Therapies used to treat psychosis include
- cognitive behavioral therapy (CBT),
- cognitive enhancement therapy (CET),

What Is the Life Expectancy for Someone Experiencing Psychosis?
