This study details a 79-year-old woman with atypical dementia and Fahr-type calcification, presenting with memory loss and behavioral changes. Neuroimaging revealed basal ganglia calcification and frontotemporal atrophy, leading to a diagnosis of diffuse neurofibrillary tangles with calcification (DNTC).

Area of Science:

  • Neurology
  • Geriatrics
  • Neuroimaging

Background:

  • Senile dementia presents with cognitive decline in older adults.
  • Fahr's disease involves abnormal calcification in the brain, particularly the basal ganglia.
  • Differentiating dementia subtypes is crucial for accurate diagnosis and management.

Observation:

  • A 79-year-old female exhibited progressive memory disturbance, visual hallucinations, and personality changes starting at age 75.
  • Brain CT showed bilateral, symmetric calcification of the basal ganglia and thalamus.
  • MRI revealed diffuse frontotemporal cortical atrophy and mixed signal intensities in calcified areas on T1-weighted images.

Findings:

  • Clinical presentation overlapped with Alzheimer's and Pick's diseases.

  • Neuroradiological findings included basal ganglia calcification and frontotemporal atrophy.
  • The patient was diagnosed with diffuse neurofibrillary tangles with calcification (DNTC).

    • Implications:

    • This case highlights the complex presentation of atypical dementia.
    • Understanding DNTC aids in diagnosing rare neurodegenerative conditions.
    • Integrated clinical and neuroimaging data are vital for characterizing novel dementia syndromes.
