catatonic schizophrenia
Noun: A subtype of schizophrenia characterized primarily by pronounced motor disturbances. These can manifest as prolonged periods of immobility and stupor (catatonic stupor) or, alternatively, as brief episodes of excessive, purposeless motor activity and excitement (catatonic excitement). The individual may exhibit a marked decrease in reactivity to the environment.
The term is used in clinical psychiatry to diagnose and describe a specific presentation of schizophrenia. - The patient was diagnosed with catatonic schizophrenia after exhibiting waxy flexibility and mutism for several days. - Treatment for catatonic schizophrenia often involves specific medications and supportive care.
- Clinical Presentation: Key features include catatonic stupor (negativism, mutism, posturing), catatonic excitement (agitation, impulsivity), and waxy flexibility (where a person's limbs can be positioned and will hold that position).
- Historical Context: This was once a more commonly specified diagnosis. Modern diagnostic manuals often categorize these symptoms under "schizophrenia" with a specifier for catatonia, reflecting that catatonia can occur in other mental and medical conditions.
- Catatonia (n): The syndrome of motor disturbances (stupor, excitement, posturing) which is the defining feature of catatonic schizophrenia. It can also occur in mood disorders or due to medical conditions.
- Catatonic (adj): Describing a state or symptoms related to catatonia. (e.g., , ).
- Catatonic type schizophrenia (clinical synonym)
- Schizophrenia, catatonic type
This term refers specifically to a historical and clinical sub-classification within the broader diagnosis of schizophrenia. The core disturbance is in motor behavior, ranging from extreme inhibition to extreme excitation, rather than being defined solely by thought disorders or hallucinations.
- a form of schizophrenia characterized by a tendency to remain in a fixed stuporous state for long periods; the catatonia may give way to short periods of extreme excitement
