Using vision to understand dementia in Parkinson’s disease

by Benedetta Biffi


Parkinson’s disease is a common debilitating neurological condition. Half of patients will develop dementia within 10 years of diagnosis but there are no robust ways of predicting who will be most affected. There is now converging evidence that patients with Parkinson’s that develop visual processing difficulties are at highest risk of dementia, but we lack sensitive measures to detect these. Rimona Weil will present research recent findings that patients with Parkinson’s are worse at recognising distorted objects and how she adapted her tests into an online testing platform to allow visuo-perceptual testing of large numbers of patients. She will then explain why this work has important potential to stratify patients for clinical trials and as disease progression measure.

Speaker bio

Dr Rimona Weil is a Wellcome Trust Clinician Scientist at the Dementia Research Centre, UCL. She is a consultant neurologist at the National Hospital for Neurology and Neurosurgery, specialising in Parkinson’s disease and cognitive disorders. Her research background is in vision science and neuroimaging. She uses psychophysical, neuroimaging and retinal imaging techniques to study visual changes in Parkinson’s disease. Her research aims to understand how dementia and hallucinations develop in Parkinson’s disease, looking for the earliest cognitive and neuroimaging changes.
