Disputes over cell phones: good or bad for brain?

Such an impact could possibly help if you suffer from migraines or other neurological disorders, the authors of a study published in the August issue of Annals of Neurology suggest. And it could hurt if you have epilepsy or a brain disease, according to Health Day News.

The researchers from Fatebenefratelli Hospital in Isola Tiberina, found that the electromagnetic field (EMF) emitted by cell phones can cause some cells in the brain's cortex adjacent to the side of phone use to become excited, while others become inhibited.

They suggest that this could have beneficial effects for people with migraines, stroke or dementia, and possibly detrimental effects for those with epilepsy, the study authors suggested.

The World Health Organization (WHO) says there have been earlier reports of cell phones affecting brain activity. But WHO concluded these effects "are small and have no apparent health significance."

The FDA says, "Available scientific evidence does not show that any health problems are associated with using wireless phones." But it also notes "there is no proof that wireless phones are absolutely safe."
The American Cancer Society says it's "unlikely" the phones cause cancer, CBS reports.

Either way, the researchers and other experts caution, much more research needs to be done before any definitive conclusions can be drawn.
