Abstract:
Psychotic symptoms include hallucinations, delusions, incoherence of thought and speech as well as exceedingly eccentric behavior. Symptoms of this kind occur in several mental disorders, such as schizophrenia, delusional disorders and psychotic mood disorders. Drugs and somatic illnesses may also cause psychosis. The assessment of the disease is based on anamnesis obtained from the patient and the family, as well as on a careful psychiatric interview and somatic examination. While treatment of psychosis is primarily attempted on an outpatient basis, hospital treatment may also be required.
