Sebastian Crutch is a neuropsychologist and Professorial Research Associate at the Dementia Research Centre, UCL Institute of Neurology. His research focuses on rare and young onset dementias, especially posterior cortical atrophy (PCA), the so-called ‘visual variant’ of Alzheimer’s disease (AD). The work has led to improved understanding of dementia-related visual impairment and the causes and consequences of atypical AD more generally. He has developed several interdisciplinary research themes collaborating with experts in social science, environmental engineering, occupational health and ophthalmology (ESRC/NIHR-funded work to ameliorate the effects of vision loss in dementia), computational statistics, virtual environments and human-computer interaction (EPSRC-funded work to enhance cognitive assessment), neurorehabilitation (Dunhill Medical Trust-funded work to design an app to facilitate reading in PCA), neurophysiology, engineering and neuro-otology (in Alzheimer’s Society-funded work to understand balance problems in AD). Currently he directs the Created Out of Mind 2016-20118 residency at The Hub, Wellcome Collection, bringing together artists, scientists and people living with dementia in a collaboration of over 60 individuals, institutions and charities aiming to shape and enrich public and professional perceptions of the dementias, and explore the opportunities afforded by collaborative, interdisciplinary, publicly-situated research.
