Insulin shock therapy in the Sixties

A scene from the movie “A Beautiful Mind“ (2001) in which mathematician and Nobel Prize laureate John Nash (Russel Crowe), in the Sixties, undergoes Insulin shock therapy as a treatment for schizophrenia, under the eyes of his wife Alicia (Jennifer Connelly). This form of shock therapy was extensively used from the 1940s to the 1960s, before falling out of favour and being replaced by neuroleptic drugs.
