Non-alcoholic Korsakoff's psychosis

Last edited: 4/15/2026

Overview

Non-alcoholic Korsakoff's psychosis, though less common than its alcoholic counterpart, refers to a state of severe anterograde amnesia and confabulation due to thiamine deficiency, typically seen outside the context of chronic alcohol misuse 1.

Diagnosis

  • Clinical presentation includes anterograde amnesia and confabulation 1.
  • Laboratory tests should focus on measuring thiamine levels (erythrocyte transketolase activity or thiamine pyrophosphate levels) to confirm deficiency 1.
  • Imaging studies (MRI) may show structural brain changes but are not diagnostic on their own 1.

    • Management

  • First-line treatment involves thiamine supplementation, typically administered intravenously (e.g., 500-1000 mg daily) to rapidly correct deficiency 1.
  • Adjunctive therapies may include multivitamins and supportive care to address nutritional deficiencies and general health 1.
  • Reversal of symptoms can be observed with prompt thiamine repletion, though recovery may be incomplete 1.

    • Special Populations

  • No specific data provided in the abstracts regarding pregnancy, pediatrics, elderly, or comorbidities 1.

    • Key Recommendations

  • Confirm thiamine deficiency through laboratory tests before initiating treatment (Evidence: Moderate 1).
  • Initiate high-dose intravenous thiamine supplementation for rapid correction of deficiency (Evidence: Moderate 1).
  • Monitor and address nutritional deficiencies broadly to support recovery (Evidence: Expert opinion 1).
