Detection of Alzheimer’s Disease from Eye Movements

Alzheimer's disease represents a growing challenge in our healthcare system as well as the loved ones and caregivers of those affected by the disease.  Efforts at early intervention are heavily dependent on our ability to detect the disease as early as possible.

Role of Eye Movements in Early Detection of Alzheimer’s Disease
According to researchers reporting in Investigative Ophthalmology & Vision Science a subtle change in eye movements may provide a useful diagnostic tool for the early diagnosis of Alzheimer’s  Disease. In general, eye movements follow a reproducible pattern during normal reading. Each eye movement ends up at a fixation point or end point. This allows the brain to process the incoming information and to program the following movements accurately. The researchers found that Alzheimer Disease (AD) produces eye movement abnormalities and disturbances in reading whereby those patients with early AD display abnormal fixation patterns. We now know that evaluation of eye movement behavior during reading may be a useful tool for a more precise early diagnosis of AD and for monitoring the progress or stability of Alzheimer’s Disease.
