Abstract

• Aphasia is a language disorder due to damage of the language center in the dominant hemisphere. I studied 42 patients whose main neurologic symptom was aphasia. In 42 aphasia patients, motor aphasia appeared in 13 pts(30.9%), sensory aphasia in 11 pts(26.1%), conduction aphasia in 5 pts(11.9%), anomic aphasia in 4 pts(9.5%), global aphasia in 4 pts(9.5%), transcortical motor aphasia in 3 pts(7.4%), transcortical sensory aphasia in 2 pts(4.7%). The most common associated pathologic condition was hypertension(85.7%) and the others were hypertriglyceridemia(42.9%), cardiac arrythmia(38.1%), transient ischemic attack(14.5%), seizure(9.5%) and hypotension(7.4%). The most common combined neurologic symptom was motor hemiparesis(26.22%), and the others were dysphagia, sensory hemianesthesia, ocular motor diturbance, agraphia, alexia, acaculia, finger agnosia and apraxia. The anomic aphasia and transcortical aphasia had best prognosis and the global aphasia had worst prognosis.
