What are the key features of catatonic schizophrenia?

Inability to move: The key feature of catatonia, which actually occurs in more than schizophrenia, is the inability to move at times. The person can stay still in one posture for hours at a time, leading to an inability to eat or perform other activities of daily living. There are also cases of "agitated catatonia" in which the person moves around in an agitated state doing motions that are purposeless.

Catalonic schizophr.: Schizophrenia entails six months of symptoms and must significantly impair functioning. The symptoms are not due to drug use or another mental illness.Symptoms may include hallucinations, delusions, disorganized speech and behavior, lack of motivation and emotional expression, low energy, poor grooming. In the catatonic subtype, there is either little to no movement or excessive movement.
