New Ways to Fight Alzheimer's and Brain Injuries
The researchers conclude that the findings could mean electromagnetic field exposure might be an effective, noninvasive, and drug-free way to prevent and treat Alzheimer's disease in humans.
"If we can determine the best set of electromagnetic parameters to effectively prevent beta-amyloid aggregation and remove pre-existing beta-amyloid deposits from the brain, this technology could be quickly translated to human benefit against AD [Alzheimer's disease]," says study researcher Chuanhai Cao, PhD, also of the University of South Florida. "Since production and aggregation of beta-amyloid occurs in traumatic brain injury, particularly soldiers during war, the therapeutic impact of our findings may extend beyond Alzheimer's disease."
Cao says the study "provides evidence that long-term cell phone use is not harmful to [the] brain," Cao says. "To the contrary, the electromagnetic waves emitted by cell phones could actually improve normal memory and be an effective therapy against memory impairment."
They note that previous human studies of electromagnetic waves from cell phones involved only brief exposures.
Although some people have claimed that cell phones may cause brain tumors, the South Florida researchers say that "despite numerous studies, there is no definitive evidence that high-frequency electromagnetic field exposure is a risk to human health" and their study suggests the waves may be beneficial.
A study published in December 2009 in the Journal of the National Cancer Institute found no substantial change in the incidence trend of brain tumors among a study group of 60,000 people five to 10 years after cell phone usage rose sharply in the countries where they lived.
