If you're hoping to stay sharp in your old age, go pick up a cell phone.
A new study suggests that prolonged cell phone use may actually help reduce and reverse the affect of Alzheimer's disease, according to researchers at the University of South Florida.
Dozens of mice were exposed to cell phone radiation for two hours a day over a seven to nine months, and in mice genetically programmed to develop Alzheimer's disease, memory and thinking skills were protected.
For mice who were already beginning to show symptom's of the disease, memory impairment disappeared. The harmful amyloid plaques that build up in the brain as the disease progresses were erased.
"Any evidence, even from mice, is promising," said Richard Isaacson, a neurologist at the University of Miami. "I think that still a ton of work needs to be done but at least it shows a glimmer of hope with some of the treatment."
Science has been on the side of cell phone companies in the past few months.
In December, the Journal of the National Cancer Institute published a 30-year study that showed no increased incidents of brain cancer among cell phone users.
If these studies hold up, it looks like all those cell phone urban legends may need to be rewritten.
