This study details a rare case of late-onset chorea and dementia caused by vascular pathology, specifically hypertension-related brain changes, mimicking Huntington's disease.

Area of Science:

  • Neurology
  • Neuroscience
  • Pathology

Background:

  • Systemic hypertension is a common condition with known neurological complications.
  • Late-onset chorea and dementia can present diagnostic challenges, sometimes mimicking neurodegenerative disorders like Huntington's disease.

Observation:

  • A 70-year-old patient with a history of hypertension developed progressive chorea and dementia.
  • Clinical presentation lacked typical features of Huntington's disease or other hereditary conditions.

Findings:

  • Postmortem examination revealed congophilic angiopathy and atherosclerosis affecting the neostriatum, leading to neuronal loss and gliosis.
  • Cortical examination showed Alzheimer's-type plaques and neurofibrillary tangles.

Implications:

  • This case highlights a rare vascular etiology for late-onset chorea and dementia.
  • It underscores the importance of considering vascular contributions in atypical dementia presentations.
  • The findings suggest a complex interplay between vascular disease and Alzheimer's-type pathology in the aging brain.
