Controversy has often surrounded psychiatry, and the term anti-psychiatry was coined by psychiatrist David Cooper in 1967. The anti-psychiatry message is that psychiatric treatments are ultimately more damaging than helpful to patients, and psychiatry's history involves what may now be seen as dangerous treatments. Electroconvulsive therapy was one of these, which was used widely between the 1930s and 1960s. Lobotomy was another practice that was ultimately seen as too invasive and brutal. Diazepam and other sedatives were sometimes over-prescribed, which led to an epidemic of dependence. There was also concern about the large increase in prescribing psychiatric drugs for children. Some charismatic psychiatrists came to personify the movement against psychiatry. The most influential of these was R.D. Laing who wrote a series of best-selling books, including "The Divided Self". Thomas Szasz wrote "The Myth of Mental Illness". Some ex-patient groups have become militantly anti-psychiatric, often referring to themselves as "survivors". Giorgio Antonucci has questioned the basis of psychiatry through his work on the dismantling of two psychiatric hospitals (in the city of Imola), carried out from 1973 to 1996.
