Corticobasal degeneration (CBD) can present with unusual visuospatial problems. Pathological findings in these cases highlight visual cortex involvement, suggesting a broader diagnostic scope for CBD.

Area of Science:

  • Neuroscience
  • Neuropathology

Background:

  • Corticobasal degeneration (CBD) is a progressive neurodegenerative disorder.
  • Typical symptoms include asymmetric rigidity and apraxia.
  • Non-motor presentations are less common but recognized.

Observation:

  • Two patients with pathologically confirmed CBD presented with significant visuospatial dysfunction.
  • This presentation differed from the typical motor symptoms in most CBD cases.

Findings:

  • Pathological examination revealed maximal changes in the visual association cortices in these patients.
  • These specific pathological findings were absent in 31 CBD cases with more typical symptoms.

Implications:

  • Corticobasal degeneration should be considered in the differential diagnosis of posterior cerebral dysfunction.
