Alzheimer’s Eye Test Could Save Doctors Time and Money

Earlier detection of Alzheimer’s disease may be possible through a beta amyloid eye test. This test looks for spots in the retina that correlate with high levels of the brain protein beta amyloid. The spots can be detected during a routine eye exam. This could save doctors time and money on expensive scans.

Although there is no known cure for Alzheimer’s, early detection is the key to effective treatment. Studies have shown that medications that are prescribed for the symptoms of Alzheimer’s are most effective when prescribed at the earliest stages. Moreover, early detection is essential for doctors to give the best care possible. Currently, only spinal taps and PET scans can detect the early signs of Alzheimer’s, and they are expensive and invasive. However, the eye test can be used as a non-invasive, low-cost screening tool for patients at high risk for the disease.
