Korsakoff Syndrome: Symptoms, Causes, Treatment
متلازمة كورساكوف
Korsakoff syndrome is a persistent memory disorder associated with brain injury from thiamine deficiency, often following Wernicke encephalopathy. It requires assessment, treatment, rehabilitation and practical longer-term support.
What is Korsakoff Syndrome?
A person may speak fluently yet struggle to remember recent events or form new memories. Inaccurate accounts may fill memory gaps without deliberate lying.

Symptoms
Forgetting new information, repeated questions and difficulty learning tasks are typical. Planning or motivation may be affected, while older memories can be better preserved.
Causes
Severe or prolonged vitamin B1 deficiency causes injury. Alcohol-associated malnutrition is common, but prolonged vomiting, malabsorption and other nutritional problems can also contribute.
Risk factors
Untreated thiamine deficiency, delayed Wernicke treatment and recurrent malnutrition are key risks. Coexisting alcohol-use disorder and poor nutrition strengthen the need for prevention and monitoring.
Diagnosis
Evaluation reviews nutrition, history, memory and daily functioning and excludes other causes of confusion or dementia. Blood tests, imaging and cognitive testing after acute stabilization may help.
Treatment
Care includes thiamine replacement, nutrition and cause treatment, with medically supported alcohol cessation when relevant. Memory rehabilitation, routine and assistance help; supplement route and duration are individualized.
Complications
Memory problems may persist and affect independence, adherence and safety. Recovery varies and ongoing care may be needed; supplements do not guarantee complete memory restoration.
Prevention
Early treatment of thiamine deficiency and Wernicke encephalopathy, regular nutrition and follow-up reduce further injury. Clear reminders and support with medicines, money and safety can aid daily life.
When to see a doctor
Persistent memory difficulty warrants assessment. Sudden confusion, poor balance or visual changes need urgent care for possible acute recurrence or another new cause.
