BBC Website today: "California researchers believe they have found a way of improving brain cell communication by injecting a drug called etanercept into the neck. " http://news.bbc.co.uk/1/hi/health/7341368.stm "In video footage, supplied and edited by the clinic, a nurse sits down with 82-year old Marvin Miller, who frowns and mumbles incoherently as she asks him a series of basic questions. He fails to recognise everyday objects including a bracelet and a pencil. Shortly afterwards he is injected with his first dose of etanercept. Five minutes later - according to the footage - he greets his wife, who stands visibly shocked, saying he has not recognised her for years."
