Hundreds of mentally ill patients who were subjected to barbaric CIA-funded brainwashing experiments ... could be entitled to compensation following a landmark court ruling. Doctor Ewan Cameron, who became one of the world's leading psychiatrists, developed techniques used by Nazi scientists to wipe out the existing personalities of people in his care. Cameron ... was recruited by the CIA during the cold war while working at McGill University in Montreal, Canada. He carried out mind-control experiments using drugs such as LSD on hundreds of patients, but only 77 of them were awarded compensation. Now a landmark ruling by a Federal Court judge in Montreal will allow more than 250 former patients, whose claims were rejected, to seek compensation. Last week, Alan Stein, of Montreal law firm Stein and Stein ... confirmed he was in the process of contacting former clients who could now renew their appeal. There are about 200 people still due compensation," he said. Using techniques similar to those portrayed in the celebrated novel the Manchurian Candidate, it was believed that people could be brainwashed and reprogrammed to carry out specific acts. Cameron developed a range of depatterning "treatments". Patients were woken from drug-induced stupors two or three times a day for multiple electric shocks. In a specially designed "sleep room" made famous by Anne Collins's book of the same name, Cameron placed a speaker under the patient's pillow and relayed negative messages for 16 hours a day. Cameron ... rose to become the first president of the World Psychiatric Association.
