Using mobiles may prevent Alzheimer’s

world Updated: Jan 08, 2010 00:22 IST

A cell phone, much maligned for its radiations that might cause cancer, actually protects or even reverses Alzhemier’s, says a new study.

“It surprised us to find that cell phone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimer’s,” said Gary Arendash, who led the study and is a research professor at Alzheimer’s Disease Research Centre, University of South Florida.

“It was even more astonishing that the electromagnetic waves generated by cell phones actually reversed memory impairment in old Alzheimer’s mice,” he said.

The researchers showed that exposing old Alzheimer’s mice to such electromagnetic waves erased brain deposits of the harmful protein beta-amyloid, besides preventing its build-up in younger Alzheimer’s mice.

The sticky brain plaques formed by the abnormal accumulation of beta amyloid are a hallmark of Alzheimer’s disease.

Most treatments against Alzheimer’s try to target beta-amyloid.
