WERNICKE-KORSAKOFF SYNDROME

Wernicke-Korsakoff Syndrome: A Comprehensive Overview

Abstract
Wernicke-Korsakoff Syndrome (WKS) is a neurological disorder that is caused by thiamine deficiency. It is characterized by two distinct syndromes: Wernicke’s encephalopathy and Korsakoff’s psychosis. Wernicke’s encephalopathy is a neurological disorder characterized by confusion, ataxia, and ophthalmoplegia. Korsakoff’s psychosis is characterized by memory impairment, disorientation, confabulation, and apathy. WKS can be caused by chronic alcohol abuse, malnutrition, or other illnesses and treatments that can interfere with thiamine absorption. This review provides an overview of WKS, including its causative factors, clinical presentations, and treatments.

Introduction
Wernicke-Korsakoff Syndrome (WKS) is a neurological disorder caused by thiamine (vitamin B1) deficiency. It is characterized by two distinct syndromes: Wernicke’s encephalopathy and Korsakoff’s psychosis. Wernicke’s encephalopathy is a neurological disorder characterized by confusion, ataxia, and ophthalmoplegia. Korsakoff’s psychosis is characterized by memory impairment, disorientation, confabulation, and apathy (Wernicke-Korsakoff Syndrome Study Group, 2001). WKS is often caused by chronic alcohol abuse, malnutrition, or other illnesses and treatments that can interfere with thiamine absorption.

Causes
The most common cause of WKS is chronic alcohol abuse. Alcohol interferes with the absorption of thiamine, leading to its deficiency. Malnutrition, gastrointestinal diseases, and pancreatic diseases may also cause thiamine deficiency. Other causes of WKS include cancer chemotherapy, haemodialysis, and certain medications (Nishimura, 2004).

Clinical Presentations
The clinical presentations of WKS vary depending on the underlying cause. Wernicke’s encephalopathy is characterized by confusion, ataxia, and ophthalmoplegia. Ataxia is the loss of coordination and difficulty in walking. Ophthalmoplegia is the paralysis of eye muscles. Korsakoff’s psychosis is characterized by memory impairment, disorientation, confabulation, and apathy. It is also associated with anterograde amnesia, which is the inability to form new memories (Wernicke-Korsakoff Syndrome Study Group, 2001).

Treatments
The primary treatment for WKS is thiamine supplementation. Intravenous thiamine is recommended for patients with severe thiamine deficiency. Other treatments for WKS include nutritional supplementation, physical therapy, and cognitive-behavioral therapies. In some cases, medications such as benzodiazepines or antipsychotics may be prescribed to treat the symptoms of WKS (Nishimura, 2004).

Conclusion
Wernicke-Korsakoff Syndrome is a neurological disorder caused by thiamine deficiency. It is characterized by two distinct syndromes: Wernicke’s encephalopathy and Korsakoff’s psychosis. WKS is often caused by chronic alcohol abuse, malnutrition, or other illnesses and treatments that can interfere with thiamine absorption. The primary treatment for WKS is thiamine supplementation, and other treatments include nutritional supplementation, physical therapy, and cognitive-behavioral therapies.
