Summary

Giant cell arteritis (GCA) can cause rapid dementia in the elderly. Early diagnosis via temporal artery biopsy and treatment with glucocorticoids can lead to recovery.

Area of Science:

  • Neurology
  • Rheumatology
  • Geriatrics

Background:

  • Giant cell arteritis (GCA) is a systemic vasculitis primarily affecting large and medium arteries.
  • Neurological manifestations of GCA, though recognized, are often underdiagnosed.
  • Dementia in the elderly can have multiple etiologies, necessitating a broad differential diagnosis.

Observation:

  • A case presentation of an elderly patient experiencing acute mental confusion and physical decline.
  • The patient's symptoms were attributed to giant cell arteritis.
  • Initial presentation mimicked other causes of dementia, highlighting diagnostic challenges.

Findings:

  • Systemic glucocorticoid therapy resulted in significant improvement of neuropsychiatric symptoms.
  • Complete physical recovery was observed following treatment.
  • Elevated erythrocyte sedimentation rate (ESR) in elderly patients with dementia of unknown origin warrants further investigation.

Implications:

  • Giant cell arteritis should be considered a treatable cause of dementia in the elderly population.
  • Temporal artery biopsy is a crucial diagnostic tool for suspected GCA in elderly individuals presenting with dementia and elevated ESR.
  • Timely diagnosis and intervention in GCA can prevent irreversible neurological damage and improve patient outcomes.
