Michael Kopelman is Professor of Neuropsychiatry at King’s College London. He has also made important contributions to the study of anterograde amnesia and relating the nature of the underlying brain damage to its neuropsychological consequences. He has also contributed to understanding the role of cholinergic depletion in Alzheimer’s dementia and Korsakoff syndrome. He is one of the few people with real expertise in the study of psychogenic amnesia. He is much in demand as an expert witness, particularly in human rights and Appeal Court cases, where he has been involved in the overturning of a range of unsound convictions.
