Area of Science:

  • Neuroscience
  • Neurology
  • Speech-Language Pathology

Background:

  • Primary progressive aphasia (PPA) is a neurodegenerative disorder characterized by gradual language decline.
  • This case explores an atypical presentation of PPA with subsequent dysphagia.

Observation:

  • A 71-year-old man with progressive language decline developed swallowing difficulties.
  • Imaging revealed left sylvian fissure widening and left temporal lobe hypometabolism.
  • Videofluoroesophagography showed deficits in oral preparation and oral phases of swallowing.

Findings:

  • The patient exhibited oral apraxia, impacting his ability to perform oral tasks.
  • Swallowing difficulties were attributed to oral apraxia, not motor or sensory deficits.
  • This presentation expands the known spectrum of PPA.

Implications:

  • Oral apraxia can manifest as dysphagia in PPA, highlighting diagnostic complexity.
  • Understanding this heterogeneity is crucial for accurate diagnosis and patient management.
  • Further research is needed to explore the link between PPA subtypes and specific motor speech impairments.
