New blood tests accurately detect Alzheimer’s disease in adults with Down syndrome
People with Down syndrome face an elevated risk of developing Alzheimer's disease. A recent study indicates that simple blood tests can accurately detect early brain changes, paving the way for easier diagnosis and inclusive clinical trials.
A recent study published in Communications Medicine has shown that newly developed blood tests can accurately detect signs of Alzheimer's disease in adults with Down syndrome. These tests measure specific proteins in the blood, providing an easier and less invasive alternative to brain scans or spinal taps. The research, conducted by scientists from the University of Southern California, the University of Wisconsin-Madison, and C2N Diagnostics, involved analyzing data from 39 adults with Down syndrome aged 25 to 55.
The study found that 20.5% of the participants had elevated levels of amyloid in their brain, which is a primary hallmark of Alzheimer's disease. This discovery could lead to earlier identification of Alzheimer's changes in this high-risk population, ultimately improving healthcare outcomes for individuals with Down syndrome.
