Korsakoff's psychosis in Scotland: evidence for increased prevalence and regional variation

Surveys of new long-stay mental hospital patients in Scotland find that 9% have a diagnosis of alcohol-related brain damage, mainly Korsakoff's psychosis (KP), whereas the rate was 5% in the old long-stay patients. The national hospital database shows a rise in rates of KP in figures for discharge diagnosis and for diagnosis of hospital residents during the past three decades. There is an argument for more specialized provision given the significance of this group of patients.
