Types of Schizophrenia
Paranoid:
Characterized by delusions and auditory hallucinations (hearing sounds that others cannot hear). People with paranoid-type schizophrenia can exhibit anger, anxiety, and can be argumentative. |
Disorganized:
Characterized by speech and behavior that are disorganized or difficult to understand, and flattening or inappropriate emotions. Normal daily activities such as showering or dressing may be disrupted. |
Residual:
Characterized by a past history of at least one episode of schizophrenia, but the person currently has no "positive" symptoms (such as delusions, hallucinations, disorganized speech, or behavior). It may represent a transition between a full-blown episode and complete remission, or it may continue for years without any psychotic episodes |
Catatonic:
Characterized by disturbances in movement. Actions that appear relatively purposeless are repetitively performed or people may exhibit a dramatic reduction in activity, to the point that voluntary movement stops, as in catatonic stupor. Alternatively, activity can dramatically increase, a state known as catatonic excitement. |
Undifferentiated:
Characterized by people who have symptoms of schizophrenia that are not sufficiently formed or specific enough to permit classification of the illness into one of the other subtypes. The symptoms of a person can fluctuate at different points in time., which results in uncertainty in classification type. |
