title: Late-onset bipolar disorder due to hyperthyroidism.
abstract: OBJECTIVE
  Bipolar disorder starts typically in early age and late-onset cases are rare. Late-onset cases are more likely to have comorbid medical illnesses responsible for them. This case report highlights late-onset bipolar disorder due to hyperthyroidism.
  
  
  METHODS
  A 65-year-old patient of bipolar disorder has been described.
  
  
  RESULTS
  Physical examination and laboratory investigations detected presence of hyperthyroidism and the patient was treated with antithyroid and anxiolytics.
  
  
  CONCLUSIONS
  A thorough examination and investigation are required in late-onset cases of bipolar disorder to rule out secondary causes. Definitive antimanic agents or mood stabilizers may not be required in such cases.
