A New Blood Test Could Reveal Your Risk of Alzheimer’s – SheKnows

A faster and more affordable way to assess the risk of developing Alzheimer’s may soon be available. Phosphorylated tau 217 (p-tau217) and beta amyloid are key biomarkers for the disease, typically only detectable via brain scans or spinal taps. However, a recent study published in JAMA Neurology found that a blood test could identify p-tau217. This test was up to 96% accurate in identifying elevated beta amyloid levels and up to 97% accurate in identifying p-tau217. While the test is not yet available to the public, it could revolutionize how Alzheimer’s is diagnosed and bring the process to a more equitable and accessible level. This test could allow physicians to direct patients to specialists sooner, potentially saving time and money in the diagnostic process. Experts stress that, while genetics play a significant role in Alzheimer’s risk, lifestyle factors such as regular exercise, good sleep habits, and mental stimulation have been shown to lower the risk of developing the disease.
