technovelgy Do you have a really bad memory, or past heartache, that you would prefer to forget? Researchers at Harvard and McGill University (in Montreal) are working on an amnesia drug that blocks or deletes bad memories. The technique seems to allow psychiatrists to disrupt the biochemical pathways that allow a memory to be recalled. In a new study, published in the Journal of Psychiatric Research, the drug propranolol is used along with therapy to ‘dampen’ memories of trauma victims. They treated 19 accident or rape victims for ten days, during which the patients were asked to describe their memories of the traumatic event that had happened 10 years earlier. Some patients were given the drug, which is also used to treat amnesia, while others were given a placebo. A week later, they found that patients given the drug showed fewer signs of stress when recalling their trauma. Similar research led by Professor Joseph LeDoux has been carried out at New York University on rats; scientists were able to remove a specific memory from the brains of rats while leaving the rest of the animals’ memories intact. An amnesia drug called U0126 was administered. […]
