However, even severe psychotic disorders usually are treatable.

Schizophrenia: People with this illness have changes in behavior and other symptoms -- such as delusions and hallucinations -- that last longer than six months, usually with a decline in work, school, and social functioning.

Schizoaffective disorder: People with this illness have symptoms of both schizophrenia and a mood disorder, such as depression or bipolar disorder.

Schizophreniform disorder: People with this illness have symptoms of schizophrenia, but the symptoms last between one and six months.

Brief psychotic disorder: People with this illness have sudden, short periods of psychotic behavior, often in response to a very stressful event, such as a death in the family. Recovery is often quick -- usually less than a month.

Delusional disorder: People with this illness have a delusion (a false, fixed belief) involving real-life situations that could be true, such as being followed, being conspired against, or having a disease. These delusions persist for at least one month.

Shared psychotic disorder (also called folie à deux) : This illness occurs when one person in a relationship has a delusion that the other person in the relationship adopts for him or herself.

Substance-induced psychotic disorder: This condition is caused by the use of or withdrawal from some substances, such as hallucinogens and crack cocaine, that may cause hallucinations, delusions, or confused speech.

Psychotic disorder due to a medical condition: Hallucinations, delusions, or other symptoms may be the result of another illness that affects brain function, such as a head injury or brain tumor.

Paraphrenia: This is a type of schizophrenia that starts late in life and occurs in the elderly population.

What Are the Symptoms of a Psychotic Disorder?
