Proteins in Eye's Nerve Cells Linked to Alzheimer's Disease

An abnormal form of the tau protein found to accumulate in the brains of Alzheimer's disease patients also accumulates in the eyes of patients with the condition, according to new findings from Cedars-Sinai investigators. The study, reported in the journal Acta Neuropathologica Communications, presents the first evidence that abnormal tau accumulates in specialized nerve cells in the eyes of patients with Alzheimer's disease and links this accumulation to deterioration of brain function.
