The expressive type of dysphasia affects language output and speech. There are two main types of expressive dysphasia: Broca's dysphasia and transcortical dysphasia. Broca's involves damage to an area of the brain called Broca's area, which is directly responsible for the production of speech. People with this condition find it extremely difficult to form words. Transcortical dysphasia affects the nerve fibers that carry information between the brain's language centers and can affect other parts of communication such as tone of voice, facial expressions, and emotion.
