From the Guidelines

Wet brain, or Wernicke-Korsakoff syndrome, requires immediate treatment with thiamine supplementation, typically 100-500 mg/day for 12-24 weeks, to prevent permanent brain damage, coma, or death. This condition is a severe neurological disorder caused by thiamine (vitamin B1) deficiency, most commonly resulting from chronic alcohol abuse. The disorder consists of two phases: Wernicke's encephalopathy (acute) and Korsakoff's psychosis (chronic) 1.

Treatment and Management

The treatment of Wernicke-Korsakoff syndrome involves thiamine supplementation, with the goal of preventing further brain damage and improving symptoms. According to the most recent guidelines, thiamine should be administered at a dose of 100-500 mg/day for 12-24 weeks 1. It is essential to note that thiamine should be given before administering IV fluids containing glucose, as glucose can precipitate acute thiamine deficiency 1.

Importance of Early Treatment

Early treatment is crucial in preventing long-term brain damage and improving outcomes. Without prompt treatment, Wernicke-Korsakoff syndrome can lead to permanent brain damage, coma, or death. The condition manifests with symptoms including confusion, memory problems, coordination difficulties, abnormal eye movements, and confabulation (making up stories) 1.

Comprehensive Management

Comprehensive management of Wernicke-Korsakoff syndrome includes nutritional support, cognitive rehabilitation, and addressing underlying alcohol use disorder through counseling or medication. Complete alcohol abstinence is essential for any recovery. The disorder occurs because alcohol interferes with thiamine absorption and utilization, while also increasing the body's thiamine requirements 1.

Key Considerations

Key considerations in the management of Wernicke-Korsakoff syndrome include:

  • Immediate thiamine supplementation to prevent further brain damage
  • Complete alcohol abstinence to support recovery
  • Nutritional support to address underlying nutritional deficiencies
  • Cognitive rehabilitation to improve cognitive function
  • Addressing underlying alcohol use disorder through counseling or medication to prevent relapse 1.

From the Research

Definition and Causes of Wet Brain

  • Wet brain, also known as Wernicke-Korsakoff syndrome (WKS), is a potentially debilitating and fatal condition caused by thiamine (vitamin B1) deficiency in the brain 2.
  • The primary cause of WKS is thiamine deficiency, and more than 90% of cases are reported in alcohol-dependent patients 3.
  • Chronic alcohol use is associated with deficiency of thiamine along with other vitamins through several mechanisms 4.

Symptoms and Diagnosis

  • WKS can be treated effectively or prevented completely; however, the condition is often undiagnosed and inadequately managed 2.
  • Symptoms of WKS include cognitive impairment, ataxia, oculomotor abnormalities, and confusion 3, 5.
  • A systematic approach helps to ensure that patients receive a prompt diagnosis and adequate treatment 5.

Treatment and Prevention

  • Parenteral thiamine administration drastically reduced WKS-related mortality 3.
  • High-dose thiamine replacement is suggested for WKS and related thiamine deficiency conditions associated with alcohol use disorder 4.
  • B-complex vitamins, including thiamine, can be used in the prophylaxis and treatment of WKS 6.
  • The optimum dose of parenteral thiamine required for prophylaxis and treatment of Wernicke's encephalopathy and prevention of Korsakoff's syndrome associated with alcohol misuse is still a topic of research 3, 5.
