Scientists look to blood tests to spot dementia risk early on
Fox News
A recent study out of Mississippi indicated a blood test was useful in determining patients facing an increased risk in cognitive decline, decades ahead of symptom onset.
Researchers with the University of Mississippi Medical Center published findings on Aug. 4 in the Neurology journal, drawing on 2,284 patients with an average age of about 59. The team analyzed blood plasma levels collected over a 25-year span for an amyloid protein; beta-amyloid can become toxic when it accumulates in the brain, contributing to Alzheimer’s disease. "In a healthy brain, this protein is cleared into the cerebrospinal fluid and into the blood stream," Dr. Kevin Sullivan, lead study author and researcher at the Memory Impairment and Neurodegenerative Dementia (MIND) Center at UMMC, said in a news release. "Detecting a higher amount of this amyloid variant in the blood is actually a good sign in terms of dementia risk."
