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.
