Although no longer recognized as a diagnosis, catatonic schizophrenia is a rare type of schizophrenia that occurs alongside catatonia, often characterized by rigid posture and movements, or even complete immobility. Someone with catatonic schizophrenia may seem to be in a trance-like state, unable to talk or react to the world around them. Conversely, some people with catatonic schizophrenia may appear agitated and excited, sometimes repeating the words or movements of other people. Or they can display a combination of both withdrawn and agitated symptoms.
