STUPOR is a state of complete immobility with mutism and weakened reactions to irritations. Depressive stupor develops at the height of depression and can suddenly be replaced by violent arousal with suicidal actions (see Depression). Patients are subject to immediate hospitalization with enhanced supervision, care, and sometimes artificial feeding. Treatment: a combination of antidepressants with antipsychotics administered intramuscularly; electroconvulsive therapy. Catatonic stupor is observed in various mental illnesses (schizophrenia, somatogeny, organic damage to the central nervous system) and is characterized by inhibition with freezing in unnatural, pretentious poses, untidiness. Treatment is carried out only in a psychiatric hospital. Psychogenic (reactive) stupor occurs as a result of severe mental trauma, as a reaction to the latter. It requires the supervision of a psychiatrist and treatment with intramuscular administration of tranquilizers.
