Deep Sleep Therapy was a bizarre psychiatric treatment in which drugs were used to induce a coma in patients during which the doctors would administer a variety of other mind drugs and electric shocks. The idea was that they’d awaken cured of mental disorders, ranging from depression to schizophrenia. One of the, er, “pioneers” was Dr. William Sargant in the UK who promoted the “therapy” in the 1960s and 1970s. Of course, Sargant is best known for his research on brainwashing. He’s the author of Battle for the Mind: A Physiology of Conversion and Brainwashing (1957), basically a how-to of techniques for reprogramming people. He also developed methods for implanting false memories, and was involved in the Project MKULTRA, the CIA’s mind control and chemical interrogation research program. Delightful guy. The BBC Radio 4 recently broadcast a documentary about Sargant’s Sleep Room treatments. The program is titled Revealing the Mind Minder General
