F20-F29: Schizophrenia, schizotypal and delusional disorders

F25: Schizoaffective disorders

Schizoaffective disorders belong to a group of mental health disorders marked by a combination of symptoms of schizophrenia and mood disorder, which may include depressive or bipolar symptoms. The exact cause of these disorders isn't known but they are believed to have a genetic component. They can't be transmitted from one person to another. Schizoaffective disorders typically show symptoms such as hallucinations, delusions, depressed mood, or manic behavior. These symptoms can lead to difficulty functioning in various areas of life, including work, interpersonal relationships, or self-care. The disorders are chronic and lifelong, but with timely and appropriate treatment, the symptoms can be effectively managed and individuals can lead fulfilling lives. They primarily affect the brain and nervous system. The diagnosis is based on the presence of symptoms that meet specific clinical criteria. The progression of disease may show periods of improvement and worsening. While it's difficult to predict the course or outcome of schizoaffective disorders, early diagnosis and treatment can improve the prognosis.
