Pick's disease was an acknowledged pathological entity but considered sufficiently rare to have little clinical relevance for dementia patients presenting to neurology or psychiatry clinics. In any case it could not be distinguished from Alzheimer's disease in life. It was against this prevailing background that I set up our early onset dementia clinic with Julie Snowden as principal neuropsychologist. My early interest in cognitive neurology and dementia had been consolidated during a sabbatical in Boston in 1976, where I acquired an analytical approach to cognitive assessment and saw firsthand the value of the multidisciplinary clinic.
