Research bets on new blood tests to detect Alzheimer's
Alzheimer's is the most common cause of dementia, considered a biological process that begins with the accumulation of amyloid plaques and neurofibrillary tangles in the brain. This causes brain neurons to die rapidly and the organ to shrink.
TL;DR
- Alzheimer's disease is the most common cause of dementia, characterized by amyloid plaques and neurofibrillary tangles in the brain.
- Current diagnostic methods, such as PET scans and cerebrospinal fluid analysis, are costly and invasive.
- New research published in Nature Medicine indicates that blood tests measuring modified tau protein can predict Alzheimer's up to 20 years before symptom onset.
- The experimental blood test shows approximately 90% accuracy in detecting amyloid accumulation in the brain.
- The Alzheimer's Association has two FDA-approved investigations focused on new biomarker tests for early detection.
- These blood tests could lead to earlier diagnoses and the development of effective treatments to prevent or delay cognitive decline.
