    Summary

    A patient experienced vision changes and neurological issues linked to alcohol abuse. Prompt thiamine treatment resolved these symptoms, suggesting a thiamine deficiency may cause xanthopsia.

    Area of Science:

    • Neurology
    • Nutritional Neuroscience

    Background:

    • Alcohol abuse is a common cause of nutritional deficiencies.
    • Thiamine (vitamin B1) deficiency can lead to severe neurological complications.

    Observation:

    • A patient with a history of extensive alcohol abuse presented with xanthopsia (yellow vision), ataxia, and cognitive impairment.
    • Symptoms developed in the context of chronic alcohol consumption.

    Findings:

    • Intravenous thiamine administration (200 mg daily) led to rapid resolution of xanthopsia.
    • Normalization of ataxia and mental changes followed the improvement in vision.

    Implications:

    • Xanthopsia may serve as a clinical indicator of thiamine deficiency in patients with alcohol use disorder.
    • Early thiamine supplementation can reverse neurological and visual disturbances associated with deficiency.
