They vary widely and include difficulty speaking and understanding verbal and/or written information. In many cases, the effects of speech impairments may be overwhelming and frustrating for the patient and caregiver. This paper presents the definition, causes, and classification of aphasia. We have a better understanding of aphasia from the perspectives of phonological disorders, syntactic disorders, and pragmatic disorders. As the study of aphasia and linguistics are closely related, a combination of them will make the study of aphasia more accurate.展开更多
