Alzheimer’s blood test catches 90% of early dementia cases, study finds

Category: Health

A new blood test for cognitive decline shows a 90% accuracy rate in diagnosing Alzheimer's disease, significantly outperforming traditional diagnostic methods. The test measures plasma phosphorylated tau 217 (p-tau217) and combines it with the amyloid 42/40 ratio to enhance diagnostic precision. Experts believe that once validated, these blood tests could revolutionize Alzheimer's diagnosis and treatment, potentially reducing wait times for patients seeking new therapies.
