Two Studies Confirm Alzheimer’s Predictors

According to The New York Times, two studies published in JAMA have confirmed that the presence of amyloid plaques in people’s brains can determine who has Alzheimer’s disease and predict who will eventually develop the condition. The data, collected from 9,500 people across five continents, revealed that amyloid plaque can appear as many as 20 or 30 years before the onset of dementia symptoms, the majority of Alzheimer’s patients have amyloid and that the ApoE4 gene, known to increase Alzheimer’s risk, accelerates the accumulation of amyloid. This does not mean doctors should rush to administer amyloid scans, they are expensive, and there is no drug to treat or prevent Alzheimer’s yet. Additionally, any medication that could prevent the disease would have to be extremely safe since the patient would be exposed to such a drug for decades while they are healthy.
