Stroke-related neurogenic dysphagia can occur even without brainstem damage. Unilateral stroke signs and silent aspiration are common, necessitating videofluoroscopy for accurate diagnosis.

Area of Science:

  • Neurology
  • Swallowing Disorders

Background:

  • Neurogenic dysphagia is a common complication following stroke.
  • Dysphagia is often associated with brainstem lesions but can occur with other stroke types.

Purpose of the Study:

  • To investigate the prevalence and characteristics of neurogenic dysphagia in stroke patients.
  • To highlight the importance of diagnostic tools in identifying dysphagia, particularly in cases with subtle symptoms.

Main Methods:

  • Retrospective analysis of 21 stroke patients.
  • Clinical assessment of swallowing function, including cough and voice quality.
  • Videofluoroscopy (VFS) utilized for detailed oral and pharyngeal phase assessment.

Main Results:

  • One-third of patients exhibited unilateral stroke signs associated with dysphagia.

  • Eight patients presented with silent aspiration, characterized by fewer subjective complaints, weaker cough, and dysphonia.
  • Dysphagia was observed in patients with both unilateral and bilateral stroke involvement.

    • Conclusions:

    • Neurogenic dysphagia post-stroke is not exclusively linked to brainstem lesions.
    • Silent aspiration is a significant concern in stroke patients, often presenting with subtle symptoms.
    • Videofluoroscopy is a crucial diagnostic tool for evaluating dysphagia in all stroke types, including unilateral cases.
