Incidence and types of speech disorders in stroke patients.

The aim of the study was to determine the incidence and types of speech disorders in patients with acute stroke. The study was performed in 936 acute stroke patients admitted to University Department of Neurology, Tuzla University Clinical Center, in the period from January 1, 2007 through December 31, 2008. Out of 936 study patients, speech disorders were verified on admission in 771 (82.37%) patients. Dysarthria was present in 540 (57.69%) and aphasia in 231 (24.67%) patients. In the group with speech disturbances, dysarthria was present in 70.04% and aphasia in 29.96% of patients. During hospital stay, lethal outcome was recorded in 51 patients, significantly higher in the group with speech disorders (P = 0.004). At discharge from the hospital, speech disorders persisted in 671 (75.81%), dysarthria in 468 (69.75%), and different types of aphasia in 203 (30.25%) of 885 surviving patients. Among patients with aphasia at both admission and discharge, global aphasia was most common, followed by motor aphasia (Broca's aphasia) and nominal aphasia. Although the rate of patients with speech disorders was lower at discharge, the difference was not statistically significant. On admission, 82.37% of patients were considered to have a speech-language disorder, dysarthria being most common. Concerning the type of aphasia, global aphasia was most frequent. Study results suggested the importance and need of speech-language therapy in the early rehabilitation of post-stroke patients; it should be initiated during their hospital stay and continued at long-term.
