Gayet-Wernicke Syndrome: A Comprehensive Guide


Gayet-Wernicke syndrome (GWS) is a neurological disorder characterized by a triad of symptoms: ophthalmoplegia (paralysis of the eye muscles), ataxia (difficulty with coordination and balance), and confusion. It is caused by a deficiency of thiamine (vitamin B1), which is essential for the proper functioning of the brain and nervous system. GWS is often associated with chronic alcohol use, but it can also occur in individuals who have other conditions that lead to thiamine deficiency, such as gastrointestinal disorders, eating disorders, or cancer.


The primary cause of GWS is thiamine deficiency. Thiamine is a water-soluble vitamin that cannot be stored in the body, so it must be obtained from the diet. Good sources of thiamine include whole grains, legumes, nuts, seeds, meat, and fish. Alcoholism is the most common cause of thiamine deficiency, as alcohol interferes with the absorption, metabolism, and utilization of thiamine. Other risk factors for GWS include:

  • Gastrointestinal disorders: Conditions that affect the absorption of nutrients, such as celiac disease, Crohn’s disease, and ulcerative colitis, can increase the risk of thiamine deficiency.
  • Eating disorders: Individuals with anorexia nervosa or bulimia may restrict their intake of thiamine-rich foods, leading to deficiency.
  • Cancer: Some types of cancer, such as lung cancer and pancreatic cancer, can produce substances that interfere with thiamine metabolism.
  • Prolonged vomiting or diarrhea: These conditions can lead to dehydration and loss of electrolytes, including thiamine.
  • Medications: Certain medications, such as diuretics and antibiotics, can interfere with thiamine absorption or metabolism.


The classic triad of symptoms associated with GWS is:

  • Ophthalmoplegia: Paralysis of the eye muscles, resulting in double vision, blurred vision, and difficulty moving the eyes.
  • Ataxia: Difficulty with coordination and balance, causing unsteady gait, slurred speech, and tremors.
  • Confusion: Impaired cognitive function, ranging from mild disorientation to severe memory loss and psychosis.

Other symptoms of GWS may include:

  • Nausea and vomiting
  • Loss of appetite
  • Weakness and fatigue
  • Numbness or tingling in the hands and feet
  • Hallucinations
  • Seizures
  • Coma


GWS is typically diagnosed based on the patient’s symptoms and a physical examination. The doctor will assess the patient’s eye movements, coordination, and mental status. Blood tests can be used to confirm thiamine deficiency and rule out other potential causes of the symptoms. An MRI scan may be performed to visualize the brain and check for abnormalities.


The primary treatment for GWS is thiamine replacement therapy. Intravenous thiamine is typically used initially, followed by oral thiamine once the patient’s condition has stabilized. The dose of thiamine will vary depending on the severity of the deficiency.

Supportive care is also important to manage the patient’s symptoms and prevent complications. This may include:

  • Fluid and electrolyte replacement
  • Anti-nausea medications
  • Pain relievers
  • Physical therapy to improve coordination and balance
  • Speech therapy to address speech difficulties
  • Cognitive rehabilitation to improve memory and other cognitive functions


The prognosis for GWS depends on the severity of the deficiency and the promptness of treatment. Early diagnosis and treatment can improve the chances of recovery and prevent permanent neurological damage. However, severe cases of GWS can lead to Korsakoff syndrome, a chronic neurological disorder characterized by severe memory loss and other cognitive impairments.


The best way to prevent GWS is to maintain a healthy diet that includes plenty of thiamine-rich foods. Individuals who are at risk for thiamine deficiency, such as those with chronic alcohol use or gastrointestinal disorders, should talk to their doctor about taking a thiamine supplement.


Gayet-Wernicke syndrome is a serious neurological disorder that can lead to a range of symptoms, including ophthalmoplegia, ataxia, and confusion. It is caused by a deficiency of thiamine, which is essential for the proper functioning of the brain and nervous system. GWS is often associated with chronic alcohol use, but it can also occur in individuals with other conditions that lead to thiamine deficiency. Early diagnosis and treatment are crucial for improving the prognosis and preventing permanent neurological damage. By maintaining a healthy diet and addressing any underlying risk factors, individuals can help prevent the development of GWS.
