Saint Louis University’s School of Medicine is launching what it’s saying could be a revolutionary new therapy for the treatment of Alzheimer’s disease. It involves the surgical implantation of a device that would pump stagnant cerebrospinal fluid from the brain. Doctor George Grossberg of the University’s Department of Psychiatry is supervising the study. He says not all Alzheimer’s sufferers are eligible for the trial. Researchers are looking for those at the mid-level stages of Alzheimer’s. Those who are chosen to take part in the trial will be allowed to continue taking their medication during the course of the experiment, which is expected to last about a year.
