Answers

Researchers at Harvard and McGill University are working on an amnesia drug that blocks or deletes bad memories. The technique seems to allow psychiatrists to disrupt he biological pathways that allow a memory to be recalled. In the new study, the drug propranolol is used along with therapy to dampen memories of trauma victims. During trails, patients given the drug showed fewer signs of stress when recalling their trauma.
