TOPIC 6 - psychotic disorders Flashcards
schizoaffective disorder
characterized by an uninterrupted period of illness during which time there is a major depressive, manic, or mixed episode, concurrent with symptoms that meet the criteria for schizophrenia. The symptoms must not be a result of any substance use or abuse or be attributable to a general medical condition
schizophreniform disorder
The essential features of schizophreniform disorder are exactly the same as those of schizophrenia except the symptoms may only last a short time, and impaired social or occupational functioning is usually not apparent
brief psychotic disorder
Brief psychotic disorder is characterized by a sudden onset of psychotic symptoms (delusions, hallucinations, disorganized speech) or grossly disorganized or catatonic behavior. The episode is usually short-lived and the person returns to his or her premorbid level of functioning. These disorders are usually precipitated by extremely stressful life events.
delusional disorder
Delusional disorder involves nonbizarre delusions (situations that occur in real life, such as being followed, infected, loved at a distance, deceived by a spouse, or having a disease) of at least 1 month’s duration. The person’s ability to function is not markedly impaired, nor is the person’s behavior obviously odd or bizarre. Common types of delusions seen in this disorder are of grandeur, persecution, or jealousy; somatic delusions; and mixed delusions
shared psychotic disorder
a condition in which an individual who is in a close relationship with another individual who has a psychotic disorder with a delusion eventually comes to share the delusional beliefs either in total or in part. Apart from the shared delusion, the behavior of the person who assumes the other’s delusional behavior is not odd or unusual. Impairment of the person who shares the delusion is usually much less than that of the person who has the psychotic disorder with the delusion
substance induced psychotic disorder
Psychosis may be induced by substances (drugs of abuse, alcohol, medications, or toxins) or caused by the physiological consequences of a general medical condition (delirium, neurological conditions, metabolic conditions, hepatic or renal diseases, and many others). Medical conditions and substances of abuse must always be ruled out before a primary diagnosis of schizophrenia or other psychotic disorder can be made
