Wernicke-Korsakoff Syndrome
A neurological condition caused by severe thiamine (vitamin B1) deficiency, most often associated with chronic heavy alcohol use, involving acute confusion followed by lasting memory impairment.
Overview
Wernicke-Korsakoff syndrome refers to two related conditions caused by severe thiamine (vitamin B1) deficiency: Wernicke encephalopathy, an acute and reversible medical emergency, and Korsakoff syndrome, a chronic memory disorder that can follow if Wernicke encephalopathy is untreated or under-treated.
Signs and Symptoms
Symptoms of Wernicke encephalopathy can include confusion, abnormal eye movements, and unsteady gait; if it progresses to Korsakoff syndrome, symptoms can include severe short-term memory impairment and confabulation (unintentionally filling memory gaps with fabricated information). Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.
Causes and Risk Factors
This syndrome is most commonly caused by chronic heavy alcohol use leading to thiamine deficiency, though it can also result from other causes of severe malnutrition or thiamine deficiency.
Diagnosis
A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.
Treatment
Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.
Psychotherapy
Structured cognitive support and memory strategies may help with daily functioning once the acute phase has been treated.
Medication
Wernicke encephalopathy is a medical emergency requiring immediate high-dose thiamine replacement, ideally before any glucose administration, to prevent progression to permanent Korsakoff syndrome. Medication decisions should be made with a qualified prescribing healthcare professional. Do not start, stop, or change a prescribed medication based solely on information on this page.
Living With Wernicke-Korsakoff Syndrome
Anyone with chronic heavy alcohol use who develops confusion, unsteady gait, or vision changes should seek immediate assistance through appropriate local emergency services, as prompt thiamine treatment can prevent permanent damage.
When to Seek Professional Help
Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.
Emergency Situations
If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.
Outlook
Wernicke encephalopathy can be reversible with prompt treatment; Korsakoff syndrome, once established, often results in lasting memory impairment, though some gradual improvement can occur with sustained abstinence and nutritional support.
