Background Dysphagia frequently occurs in patients with Parkinson’s disease (PD) and is associated with severe complications. However, the underlying pathology is poorly understood at present. This study investigated the effect of cognitive and motor dual‐task interference on oropharyngeal swallowing in PD.
