What is "insulin shock therapy"

n. shock therapy#English effected by means of injecting insulin.

n. the administration of sufficient insulin to induce convulsions and coma [syn: insulin shock, insulin shock treatment]

Insulin shock therapy or insulin coma therapy (ICT) was a form of psychiatric treatment in which patients were repeatedly injected with large doses of insulin in order to produce daily comas over several weeks. It was introduced in 1927 by Austrian-American psychiatrist Manfred Sakel and used extensively in the 1940s and 1950s, mainly for schizophrenia, before falling out of favour and being replaced by neuroleptic drugs in the 1960s.

It was one of a number of physical treatments introduced into psychiatry in the first four decades of the twentieth century. These included the convulsive therapies ( cardiazol/metrazol therapy and electroconvulsive therapy), deep sleep therapy and psychosurgery. Insulin coma therapy and the convulsive therapies are collectively known as the shock therapies.
