Korsakoff syndrome (KS) is a disorder characterized by memory loss, tremor, disorientation, decreased inhibition, and vision problems.[2][3] This may result in the classic presentation of confabulation, were memory gaps are replaced with untrue information.[3] It is generally a long term, often permanent disorder.[2][3]
It occurs due to deficiency of thiamine (vitamin B1), often due to alcoholism, though other causes may also result in the condition.[2][3] The underlying mechanism involves damage to cells in the brain and spinal cord.[2] It is part of a spectrum of disease known as Wernicke–Korsakoff syndrome, together with Wernicke encephalopathy.[2] Diagnosis is based on symptoms after ruling out other causes.[3]
Treatment is initially with thiamine.[3] Electrolytes may also require replacement.[3] Long term measures may include memory rehabilitation and institutionalization.[3] Korsakoff syndrome occurs in about 80% of people with Wernicke encephalopathy that goes untreated.[4] Less than 2% of people are affected.[3] It is named after Sergei Korsakoff, a Russian neuropsychiatrist who described it in the late 19th century.[5]
