The incidence, co-occurrence, and predictors of dysphagia, dysarthria, and aphasia after first-ever acute ischemic stroke.

The incidence, co-occurrence, and predictors of dysphagia, dysarthria, and aphasia after first-ever acute ischemic stroke. J Commun Disord. 2013 Apr 12; Authors: Flowers HL, Silver FL, Fang J, Rochon E, Martino R Abstract Dysphagia, dysarthria and aphasia occur frequently following stroke. Our purpose was to identify the incidence, co-occurrence, and predictors of these impairments after first-ever ischemic stroke. We used the Registry of the Canadian Stroke Network's database (2003-2008) from one stroke center to identify a random sample of 250 patients with acute ischemic stroke confirmed by MR imaging. We further conducted a retrospective medical chart review. We established reliable data capture and identified the presence of the three impairments. We derived incidence and co-occurrence estimates along with 95% confidence intervals (CI) for dysphagia, dysarthria, and aphasia. We then computed odds ratios (OR) through logistic regression to identify predictors. Twenty-nine patient charts were not available for review. Estimates of the incidence of dysphagia, dysarthria, and aphasia were 44% (95% CI, 38-51), 42% (95% CI, 35-48) and 30% (95% CI, 25-37), respectively. The highest co-occurrence of any two impairments was 28% (95% CI, 23-34) for the presence of both dysphagia and dysarthria. Ten percent of all 221 patients had all three impairments. The highest predictors were non-alert level of consciousness for dysphagia (OR 2.6, CI 1.03-6.5),...
