Alzheimer’s disease (AD) is a progressive brain disorder that gradually destroys memory and other important mental functions. More than 90% of AD cases are the late-onset form, with symptoms not appearing until after 65 years of age.

Two abnormal structures, plaques and tangles, are detected in affected brains. These are the prime suspects for increasing cell death and tissue loss.

Plaques, made of a protein called beta-amyloid, stop the nerve cells from talking to each other. Tangles form when tau, a protein that normally forms parallel strings inside nerve cells, crumbles down into a twisted mess. Without the proper tau tracks, cells are unable to move nutrients and other essential supplies around.

The build up of plaques and tangles are responsible for the cell death, as seen in AD brains. Take this test to find out whether you are at risk, so you can start making changes to keep your brain healthy.
