Flickering Lights to Treat Alzheimer's?

Researchers are investigating a treatment for Alzheimer's disease that uses flickering lights and sound in the wake of a series of mice studies that suggest it is effective, reports WFMZ-TV in Pennsylvania. "Based on mouse studies, we do see things like we can reduce plaques in animals," said Georgia Institute of Technology Professor Annabelle Singer. Emory University Professor James Lah added that subjects in experimental trials must sit under flashing lights and repetitive sound stimulation for an hour each day for four to eight weeks. The brain emits a surge of signaling chemicals at 40 hertz that may help combat Alzheimer's. The scientists suggest this methodology also could be used to treat other neurological disorders, like Parkinson's.
