Abstract: OBJECTIVE:Stroke is the most common neurological disease that is associated with deglutition disorders. The aim of this study was to analyze dysphagia and aspiration pneumonia risk factors in post-stroke elderly inpatients. METHOD:We consecutively enrolled 212 stroke patients over sixty years of age from July 2014 to June 2015. Seventeen patients were eliminated. Stroke patients’ demographics, clinical symptoms and biochemistry data were collected. Modified water swallowing test was used for the assessment of deglutition difficulty. These inpatients were classified into two groups: territorial anterior circulation infarction (n= 114) and territorial posterior circulation infarction (n= 82). Finally, dysphagia and aspiration pneumonia risk factor were analyzed between these two groups. RESULT: Number of previous cerebral infarction, National Institutes of Health Stroke Scale (NIHSS) score, masticatory muscle paralysis, abolition of gag reflex were correlated with the deglutition difficulty in these patients. In addition, NIHSS score (p= 0.017) and dysphagia (p= 0.02) were correlated with aspiration pneumonia. CONCLUSION: In stroke inpatients over sixty years of age, it is necessary to distinguish the patients with multiple previous cerebral infarctions, high NIHSS score, masticatory muscle paralysis, and abolition of gag reflex for early detection and rehabilitation of dysphagia.
