Abstract

Introduction: Aphasias constitute an acquired disorder of the language. Aetiologies are dominated by stroke. The aim of this study was to describe the clinical, epidemiological and evolutionary aspects of the vascular aphasias.<br />Materials and Methods: We conducted from August 2003 to May 2005 a descriptive cross-sectional study at the Neurology department in Dakar. This study concerned all patients admitted at the Neurology department for stroke confirmed by the cerebral tom densitometry. All patients were subjected to an examination of the language allowing to confirm the diagnosis of aphasia and to determine the type. The follow-up was monthly during one year.<br />Results: 55 cases of aphasia were reported on 170 cases of stroke (frequency: 32.35%). Our patients were all right-handed. Mean age was 56.8 (28 to 86 years) with a sex-ratio of 0.61.76.36% of the patients could neither read nor to write. Only two made higher studies. The nature of stroke was ischemic in 73.7% and hemorrhagic in 26.3%. The aphasias with expressive language impairment were observed in 96.4% against 3.6% of the cases for aphasias with comprehensive language impairment. After one year of evolution, a regression of the disorders was observed only in 9 cases, and the regression was partial in 25 cases. The evolution of the aphasia was correlated with that of the motor deficit. Age, low educational level, ischemic stroke constitute factors of bad prognosis.<br />Conclusion: Vascular aphasias are frequent and of reserved prognosis. It disturbs social professional and family reintegration.
