New drugs for Alzheimer’s getting closer
Research findings announced this week promise continued progress in developing effective treatments for Alzheimer’s disease. Researchers at Brigham and Women’s Hospital in Boston said that they have found an enzyme that activates the debilitating disease.
The new research found evidence that suggests that a brain substance called presenilin is the enzyme that controls production of amyloid beta proteins. Some scientists have earlier stated that presenilin plays a role in Alzheimer’s.
About 40 percent of people who have “familial” Alzheimer’s, which is an inherited form of the disease, have a mutation in their presenilin genes. The mutation makes them more susceptible the accumulation of characteristic amyloid plaques in their brains.
