Alzheimer’s ‘lost’ memories may be recovered – study

TOKYO: Sufferers of Alzheimer’s disease may not have “lost” their memories, but could simply have difficulty accessing them, researchers said as they unveiled a possible treatment that could one day offer a cure to the ravages of dementia.

Nobel Prize-winner Susumu Tonegawa said studies on mice showed that by stimulating specific areas of the brain with blue light, scientists could make the creatures recall thoughts that were otherwise unavailable to them.
