Evidence suggests Alzheimer’s disease may begin years before symptoms occur
Sandy Halperin was likely around 35 years old when his brain began slowly accumulating the plaques and tangles of Alzheimer’s. By age 60, when Halperin started to lose words and forget his intentions, the disease was already advanced. Dr. Sanjay Gupta, CNN chief medical correspondent, writes that thanks to recent advances that allow us to see the disease in the living brain, there is evidence of Alzheimer’s in neural tissue 20 to 30 years before someone may notice lapses in memory.
