Catatonic involutional syndrome is the same as late catatonic syndrome.
Late catatonic syndrome manifests itself in old and senile age (usually after 60 years). It is characterized by symptoms such as stupor (complete inhibition, lack of movement and speech) or, conversely, agitation with aimless motor activity, stereotypical movements, echolalia, echopraxia, and symptoms of negativism.
The reasons for the development of late catatonic syndrome may be associated with vascular diseases of the brain, neurodegenerative diseases, and brain tumors. Diagnosis is based on the clinical picture and neurological examination data. Treatment is usually symptomatic and includes the use of antipsychotic and tranquilizing drugs. The prognosis depends on the underlying disease that caused the development of the syndrome.
