POLICY WIRE — Washington, United States — New blood tests that may predict Alzheimer’s years before symptoms begin have sparked interest among those concerned about dementia. However, medical professionals emphasize that these tests are not yet ready for widespread use and that individuals don’t need a test to start taking steps to lower their risk.

While some labs offer similar tests, experts caution that they are not recommended for people without symptoms. Instead, focusing on preventable brain risks is more effective.

Doctors advise adopting healthy habits like regular exercise, a balanced diet, and mental stimulation to protect brain health. These steps can significantly reduce the risk of cognitive decline and dementia.
