"These studies are certainly very exciting, and suggest for the first time that certain antihypertensive drugs already available to the public may independently influence memory functions while reducing degenerative pathological features of the Alzheimer’s disease brain," said study author Giulio Maria Pasinetti, MD, PhD, Saunders Family Professor of Neurology and Director of the Center of Excellence for Novel Approaches to Neurotherapeutics at Mount Sinai School of Medicine....
Dr. Pasinetti’s team found for the first time that carvedilol, a blood pressure lowering agent, is capable of exerting activities that significantly reduce Alzheimer’s disease-type brain and memory degeneration. This benefit was achieved without blood pressure lowering activity in mice genetically modified to develop Alzheimer’s disease brain degeneration and memory impairment.
They also found that carvedilol treatment was capable of promoting memory function, based on assessments of learning new tasks and information and recall of past information, which is already chemically stored in the brain. In the study, one group of mice received carvedilol treatment and the other group did not. The scientists conducted behavioral and learning tests with each group of mice, and determined that it took the mice in the carvedilol significantly less time to remember tasks than the other group.
Ongoing clinical research is in progress to test the benefits of carvedilol, which may prove to be an effective agent in the treatment of symptoms of Alzheimer’s disease, hope they will come out with positive results...
