What is it about?
We explored the role of sensory pathway in pathophysiology of post-stroke oropharyngeal dysphagia in a group of 28 chronic unilateral post-stroke patients with event-related sensory-evoked potentials to pharyngeal stimulation (pSEP). We found that chronic post-stroke oropharyngeal dysphagia is associated with stroke severity and degree of leukoaraoisis. Impaired conduction and cortical integration of pharyngeal sensory inputs at stroke site are key features of chronic post-stroke patiens with dysphagia. These findings highlight the role of sensory pathways in the pathophysiology of post-stroke oropharyngeal dysphagia and offer a potential target for future treatments.

Why is it important?
These results are important in order to better know the pathophysiology of post-stroke oropharyngeal dysphagia and offer a potential target for future treatments (sensory stimulation).
Perspectives
With these results we can confirm that the sensory pathway is a key feature associated with post-stroke OD. Thus, new studies assessing treatment adressed to increase the sensory input to recovery the swallowing function will be developed in this population of post-stroke patients with oropharyngeal dysphagia.
