Aphasia in patients with ischemic stroke.

Abstract

Aphasia in ischemic stroke patients is associated with increased mortality, decreased rates of functional recovery, and reduced work capability. The aim was to study the prevalence and characteristics of aphasia in ischemic stroke patients. This prospective, cohort study included 177 patients (94 male and 83 female) hospitalized for ischemic stroke at University Department of Neurology in Osijek in 2010. All patients were examined by a neurologist and speech therapist to specify the subtype of stroke and speech disturbance. The study showed 75 (42.4%) study patients to have aphasia (48.2% of females and 37.2% of males). The most frequent clinical type was expressive-receptive aphasia. Aphasic patients were statistically significantly older (75 vs. 70 years) and showed female predominance (53% vs. 42%). Patients with aphasia also had a threefold share of large vessel stroke (51% vs. 17%) and approximately twofold share of cardioembolic stroke (41% vs. 22%). The share of left hemisphere stroke was nearly twofold in aphasic (61%) compared to non-aphasic (31%) patients. The study showed a high prevalence of aphasia in patients with ischemic stroke, which increased with age, was more pronounced in females and most frequently found in patients suffering from large vessel stroke and cardioembolic stroke.
