Alzheimer’s Detectable as Early as 18

As with any disease, early detection is key for treating Alzheimer’s. Doctors say that certain regions of the brain have lost 20-percent of their brain cells by the time a patient begins to show signs of dementia and by then, it is too late to treat. 

James Gallagher of the BBC reports a study published in the Lancet Neurology suggests that the earliest signs of Alzheimer’s are detectable up to 15 year before any symptoms are shown. Brain scans of those as young as 18 showed differences for individuals who are likely to develop Alzheimer’s in their 40s. A protein called beta-amyloid is found at higher levels in the brain, as well. 

Drugs are being developed to stop amyloid build up and doctors are optimistic that these findings will allow for better treatment and earlier detection of Alzheimer’s.
