Metabolic causes may include the following:

  • Fluid and electrolyte abnormalities, acid-base disturbances, and hypoxia

  • Hypoglycemia

  • Hepatic or renal failure

  • Vitamin deficiency states (especially thiamine and cyanocobalamin)

  • Endocrinopathies associated with the thyroid and parathyroid

Hypoperfusion states such as shock congestive heart failure, cardiac arrhythmias, and anemias may contribute to delirium.
