Diagnosis of Aphasia
Aphasia is usually first recognized by the physician who treats the person for his or her brain injury. Most individuals will undergo a magnetic resonance imaging (MRI) or computed tomography (CT) scan to confirm the presence of a brain injury and to identify its precise location. The physician also typically tests the person's ability to understand and produce language, such as following commands, answering questions, naming objects, and carrying on a conversation.
If the physician suspects aphasia, the patient is usually referred to a speech-language pathologist, who performs a comprehensive examination of the person's communication abilities. The person's ability to speak, express ideas, converse socially, understand language, and read and write are all assessed in detail.
