Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. The neurologist who treats your brain condition will most likely recognize your aphasia and perform simple tests that require you to follow commands, answer questions, name objects, and have a conversation. You may then be referred to a speech-language pathologist, who will perform further tests to assess your speech and language skills.

Tests may include the following:

* Evaluation of speech
* Assessment of the strength and coordination of the speech muscles
* Vocabulary and grammar tests
* Comprehension tests
* Reading and writing tests
* Swallowing tests
* MRI scan —a test that uses magnetic waves to make pictures of structures inside the head
* CT scan —an x-ray that uses a computer to make images of structures inside the head
* Electroencephalogram (EEG) —a test that records brain activity by measuring electrical currents through the brain. This test may be done in some situations.
