Mobiles may help to tackle dementia

Mobile phones may improve memory and protect against Alzheimer's disease, scientists have discovered.

They say that the electromagnetic waves emitted by the devices may improve cognitive function.

After years of health warnings, scientists in Florida admit they were as surprised as anyone when their research showed they might be good for the brain.

But they have enough confidence in their results to recommend that the electro-magnetic waves the phones emit should be "vigorously investigated" as a treatment for Alzheimer's.


Scientists in the Department of Cell Biology at the University of South Florida carried out their research on mice. They were given two one-hour doses of radiation -- equivalent to that of a frequent mobile phone user.

Half of the mice were genetically engineered to have symptoms of Alzheimer's disease. When bombarded with electromagnetic waves, they had fewer of the symptoms of dementia.

Rebecca Wood, chief executive of the Alzheimer's Research Trust, said: "We don't recommend spending 24 hours a day on a mobile phone -- we don't know the long-term effects, and bills could go through the roof."
