Professor Dennis Chan

Professor Dennis Chan at OneWelbeck is an academic neurologist and an international authority on the early detection of Alzheimer's disease. He leads a research team based at the UCL Institute of Cognitive Neuroscience while his clinical work is based at University Hospitals Sussex NHS Trust where he runs a specialist memory clinic. His primary interest is the detection of preclinical Alzheimer’s disease (AD) and he has pioneered the use of next generation digital technologies including virtual reality, augmented reality and app-based tests. His research work encompasses testing of people at risk of developing dementia, aiming not only to improve early diagnosis but also to identify approaches that protect brain function and reduce risk of future dementia.

Professor Dennis Chan remains clinically active, with NHS work focusing mainly on the diagnosis and treatment of people with mild cognitive impairment and Alzheimer's disease using gold standard tests including high resolution MRI, PET scans and lumbar punctures with high sensitivity and specificity for Alzheimer's disease. He also undertakes general neurology work covering other diseases such as Parkinson's disease, headaches and epilepsy though his main expertise is in memory disorders.

Professor Dennis Chan receives grant funding from the Wellcome Trust, Alzheimer’s Research UK, the National Institute for Health Research and the UK Dementia Research Institute.
