Alzheimer's Drug May Prevent Damage Caused By Traumatic Brain Injuries

A new class of Alzheimer's disease drugs may prevent long-term damage from traumatic brain injury, suggests a study of mice by Georgetown University Medical Center researchers.

The drugs -- gamma-secretase inhibitors -- are designed to target amyloid plaque that accumulates in the brains of people with Alzheimer's disease, according to background information in the study.

What researchers have found is that this plaque begins to accumulate one day after a traumatic brain injury takes place. It is also known that people who've suffered a brain injury have a 400 percent increased risk of developing Alzheimer's disease.

The study is published in this month’s Nature Medicine.
