Dysphagia with aspiration is prevalent in acute stroke; however, noninvasive clinical screening assessments to identify patients at risk of developing aspiration are limited. This study was undertaken to determine whether risk factors detected in the clinical examination approximated the videofluoroscopic swallow study (VSS) in identification of dysphagia severity. Six clinical features—dysphonia, dysarthria, abnormal volitional cough, abnormal gag reflex, cough after swallow, and voice change after swallow—were assessed by means of an oropharyngeal evaluation and a clinical swallowing examination. Clinical assessments and VSS were completed on consecutive stroke patients ( n =59) within 5 days of hospital admission. The VSS was scored on a scale of 0 to 4 (0=normal, 1=mild, 2=moderate, 3=moderate-severe, 4=severe dysphagia). Results showed that the presence of at least 2 of the 6 clinical features consistently distinguished patients with moderate to severe dysphagia from patients with mild dysphagia/normal swallowing. These data demonstrate that this clinical dysphagia screening tool can provide objective criteria for the need for VSS in acute stroke patients.

These results provide strong evidence that adults with PDS have anomalous anatomy in perisylvian speech and language areas. No one anatomic feature distinguished the groups, but multiple loci within a widely distributed neural network differed between groups. These results provide the first evidence that anatomic anomalies within perisylvian speech-language areas may put an individual at risk for the development of stuttering.
