Stroke and dementia

Dr. Sandra Black, director of the Hurvitz Brain Sciences Research Program at SRI, studies how amyloid contributes to the biological changes that occur not only in Alzheimer’s disease, but also in strokes caused by bleeding in the brain. Her group is looking at whether amyloid in the retina correlates with its presence in the brain, and whether it can be observed in the eye before it is seen in the brain. If the technique works, then ophthalmologists could one day screen for Alzheimer’s disease and stroke.

She is also collaborating with SRI scientists Drs. Benjamin Goldstein, Peter Kertes and Victor Yang to study the link between damage to the blood vessels in the eye and bipolar disorder.
