Abstract

There are no robust features to predict which patients with Parkinson’s disease (PD) will develop dementia. Those with involvement of visual processing regions are at highest risk of dementia.1-3 However, current measures of visuoperception are poorly sensitive.4 We have developed a sensitive test of visuoperception based on the clinical observation that patients with PD have difficulty reading distorted CAPTCHA (completely automated public Turing test to tell computers and humans
apart) images
