Aphasia is an inability to comprehend and formulate language because of damage to a specific brain region. The main causes of aphasia is a cerebral vascular accident (stroke) or any sort of head trauma. However aphasia can also be a result of brain tumors, brain infections, or a neurodegenerative disease. There are three primary kinds of aphasia, which include expressive, receptive, and conduction aphasia.

Expressive aphasia, also known as Broca’s aphasia, is characterized by the partial or full loss of the ability to produce language. This includes spoken, manual, or written language. Although expressive language can be extremely difficult, the ability to understand and comprehend language remains intact. Individuals with this type of aphasia usually will be able to read, however, since the ability to produce language is impaired, writing is usually limited because of the brain’s inability to produce language in the form of writing.

Receptive aphasia, also known as Wernicke’s aphasia, is characterized by difficulty understanding written and spoken language, although other intellectual abilities are completely fine. This type of aphasia also causes an individual’s speech to be difficult to understand. What this means is they can speak in correct grammatical and syntactical sentences, but it doesn’t make a lot of sense. Because Wernicke’s aphasia affects the brain’s ability to make sense of words, reading and writing are often severely impaired.

Conduction aphasia is characterized by impairment with repetition. These individuals are able to express themselves relatively well, with only some word-finding issues, but have extreme difficulty repeating phrases, especially when they increase in length and complexity. This type of aphasia is much more rare than the other two types listed above.
