Definition

Noun: - A serious neurological disorder caused by a severe deficiency of thiamine (vitamin B1), characterized by a classic triad of symptoms: confusion, abnormal eye movements (ophthalmoplegia), and difficulty with muscle coordination (ataxia). It is most frequently associated with chronic alcoholism but can also result from other conditions that impair thiamine absorption or increase its demand.

Usage Examples

• The patient was admitted to the hospital with symptoms indicative of Wernicke's encephalopathy, including sudden confusion and unsteady gait.
• Prompt administration of intravenous thiamine is the standard treatment for suspected Wernicke's encephalopathy.
• A history of poor nutrition and alcohol dependence put him at high risk for developing Wernicke's encephalopathy.

Advanced Usage

• "Wernicke-Korsakoff syndrome": This term is often used to describe the condition when the acute phase of Wernicke's encephalopathy is followed by or coexists with Korsakoff's psychosis, a chronic memory disorder. While related, they represent different stages or aspects of the same thiamine-deficiency disease process.
  • The chronic memory impairment suggested the diagnosis had progressed from acute Wernicke's encephalopathy to full Wernicke-Korsakoff syndrome.

Variants and Related Words

• Wernicke's disease: A less common synonym for Wernicke's encephalopathy.
• Alcoholic encephalopathy: A broader term that may encompass Wernicke's encephalopathy when the etiology is alcohol-related.
• Thiamine deficiency: The direct nutritional cause of the condition.

Synonyms

• Wernicke's disease
• Alcoholic encephalopathy (when context specifies)
• Thiamine deficiency encephalopathy

Notes on Meaning

• The term specifically refers to the acute, potentially reversible phase of neurological damage caused by thiamine deficiency. It is a medical emergency. The eponym "Wernicke's" refers to the German neurologist Carl Wernicke, who first described the condition.

Noun

1. inflammatory degenerative disease of the brain caused by thiamine deficiency that is usually associated with alcoholism
