失语症是由于大脑语言中枢受到损伤而引起的,脑中风、脑肿瘤、颅内感染和头部外伤均可导致失语。失语症患者多会在理解问题和语言表达上存在困难,严重影响人感情和思想的交流。研究表明,患脑中风失语的病人,有25%在3个月之内能恢复他们的语言能力到功能水平(如能自己开口说话、理解别人的话及简单的手势表达等),另外 Aphasia is caused by damage to the brain’s central nervous system. Stroke, brain tumors, intracranial infections and head trauma can all lead to aphasia. Aphasia patients often encounter difficulties in understanding problems and language expressions, which seriously affect the exchange of human feelings and thoughts. Studies have shown that 25% of patients with aphasia can resume their language skills to functional levels within 3 months (such as being able to speak by themselves, understanding others’ words and simple gestures, etc.)
