What is Expressive Aphasia?

Expressive aphasia is a form of aphasia in which the person knows what they want to say but is unable to produce the words or sentence. It is also known as non-fluent aphasia and Broca’s aphasia, and severity can range from mild to severe. People with expressive aphasia are typically aware of their communication difficulties.

Expressive aphasia is due to damage to Broca’s area in the left hemisphere of the brain, named after French scientist Paul Broca.

Expressive aphasia is often described as having the words “on the tip of your tongue.” It is called non-fluent aphasia because speech is effortful and involves starts and stops. Another defining feature is that if sentences are produced, they often have incorrect syntax, or word order and grammar.

Comprehension, or reading and listening, are less affected than speech and written expression. Simple sentences are easiest to understand. For instance, “John likes ice cream” is easier to understand than “Ice cream is a food that is liked by John.” People with Broca’s aphasia are often able to understand most of what is said to them, but they have trouble responding.

Someone with expressive aphasia can also experience less obvious communication impairments. This can include yes/no confusion, or saying yes when they really mean no. Using the correct pronouns can also be difficult and the individual might use “he” to refer to a woman.

Speech therapy can be very helpful for people with expressive aphasia. People with expressive aphasia can improve in their communication abilities for a long time following a stroke, especially with therapy and support.
