Korsakoff syndrome

Show Summary Details

Quick Reference

An organic disorder affecting the brain that results in a memory defect in which new information fails to be learnt although events from the past are still recalled; disorientation in time and place; and a tendency to unintentionally invent material to fill memory blanks (see confabulation). The commonest cause of the condition is alcoholism, especially when this has led to deficiency of thiamine (vitamin B1). Large doses of thiamine are given as treatment. The condition often becomes chronic. S. S. Korsakoff (1854–1900), Russian neurologist
