thiamine deficiency
B1 vitamin lack
Thiamine deficiency is a lack of vitamin B1, essential for nerve function and energy metabolism.
Severe deficiency causes beriberi, affecting the heart and nervous system, or Wernicke-Korsakoff syndrome, a brain disorder common in alcoholics.
Early symptoms include fatigue, irritability, and poor concentration.
The patient's confusion was traced to thiamine deficiency from chronic drinking.
