'''Korsakoff syndrome''' is a chronic memory disorder caused by severe deficiency of [[thiamine]] (vitamin B-1). The syndrome is named after [[Sergei Korsakoff]], a Russian neuropsychiatrist who discovered the syndrome during the late 19th century. Korsakoff syndrome is most commonly caused by alcohol misuse, but can also arise from malnutrition, certain diseases, and conditions that affect the absorption of nutrients in the digestive system. | '''Korsakoff syndrome''' is a chronic memory disorder caused by severe deficiency of [[thiamine]] (vitamin B-1).

The main cause of Korsakoff syndrome is a deficiency in thiamine. Thiamine plays a crucial role in brain function, including the creation of neurotransmitters and the metabolism of glucose, the brain's primary source of energy. Chronic alcohol misuse can lead to thiamine deficiency by causing poor nutrition and also by interfering with the body's ability to absorb and store thiamine. | The main cause of Korsakoff syndrome is a deficiency in thiamine.

Korsakoff syndrome is a chronic memory disorder caused by severe deficiency of thiamine (vitamin B-1). The syndrome is named after Sergei Korsakoff, a Russian neuropsychiatrist who discovered the syndrome during the late 19th century. Korsakoff syndrome is most commonly caused by alcohol misuse, but can also arise from malnutrition, certain diseases, and conditions that affect the absorption of nutrients in the digestive system.
Causes[edit]
The main cause of Korsakoff syndrome is a deficiency in thiamine. Thiamine plays a crucial role in brain function, including the creation of neurotransmitters and the metabolism of glucose, the brain's primary source of energy. Chronic alcohol misuse can lead to thiamine deficiency by causing poor nutrition and also by interfering with the body's ability to absorb and store thiamine.
Symptoms[edit]
The hallmark symptom of Korsakoff syndrome is severe memory loss, particularly for recent events and new information. People with Korsakoff syndrome may also exhibit confabulation, or the creation of new, fictitious memories to fill in the gaps in their memory. Other symptoms can include apathy, hallucinations, and changes in personality.
Diagnosis[edit]
Diagnosis of Korsakoff syndrome is based on the patient's clinical history, symptoms, and, in some cases, brain imaging tests. There is no specific laboratory test for Korsakoff syndrome.
Treatment[edit]
Treatment for Korsakoff syndrome involves replacing thiamine, controlling symptoms, and preventing the syndrome's progression. This can involve a combination of medications, healthy diet, and abstaining from alcohol. In some cases, people with Korsakoff syndrome may need to be hospitalized or placed in a long-term care facility.
Prognosis[edit]
The prognosis for Korsakoff syndrome varies. Some people may recover completely, while others may have lasting memory impairment. Early treatment can improve the prognosis.
