    Using Brain Atrophy and Visual Dysfunction to Predict Dementia in Parkinson’s Disease

    L-A. Leyland, R. Mahmood, R. Weil (London, United Kingdom)

    Objective: To identify areas of regional volume loss in structural brain images relating to poorer visual function and risk of dementia in Parkinson’s Disease (PD).…
