Area of Science:

  • Neurology
  • Internal Medicine

Background:

  • Wernicke's encephalopathy (WE) is a serious neurological condition.
  • It is caused by thiamine deficiency, often linked to alcohol abuse.
  • Classic symptoms may be absent, complicating diagnosis.

Observation:

  • Comatose and hypothermic patients are at risk.
  • Diagnostic challenges arise when typical WE signs are missing.
  • History of alcohol abuse or thiamine deficiency may be unknown.

Findings:

  • Untreated WE has a significant mortality rate (17%).
  • Parenteral thiamine administration can reverse WE morbidity.
  • High doses of thiamine are safe and well-tolerated.

Implications:

  • Consider WE in undiagnosed comatose/hypothermic patients.
  • Administer parenteral thiamine before glucose in at-risk patients.
  • Early thiamine treatment improves outcomes and reduces mortality.
