A new study suggests that a blood test could predict the risk of developing Alzheimer's symptoms in healthy adults over 65. The test, which measures levels of p-tau217, found that adults with high levels had a 38% risk of cognitive decline within five years and a 78% risk within 10 years. However, scientists emphasize that it is too early for healthy individuals to request the test, as it is currently used to diagnose Alzheimer's in those already experiencing cognitive problems.
The study's lead author, Dr. Reisa Sperling of the Mass General Brigham Neuroscience Institute, advises individuals to maintain a healthy lifestyle, including a balanced diet, regular exercise, and sufficient sleep. The research was published in JAMA and presented at the International Alzheimer's Association Conference in London.
The Alzheimer's Association notes that the disease has a high incidence in Hispanic individuals in the US.
