Broca's Aphasia

Broca's aphasia is a language disorder that can happen when a specific area of the brain, Broca’s area, is damaged from a stroke or brain injury. Broca’s area is very close to the motor control centers for the right arm and leg, so someone with Broca’s aphasia often has weakness in their right arm or leg. Since the motor center to talk is also located in this area, they may also have apraxia of speech.

Wernicke's Aphasia

Wernicke’s aphasia is a type of fluent aphasia that can occur when a more posterior part of the left hemisphere is damaged from a stroke or brain injury. It is often thought to be harder to treat than other types of aphasia, but this isn’t true. The hallmark of this aphasia is poor understanding, but fluent speech that consists of nonsense words or words with mixed-up sounds. For example, saying “She wersh complirest over againer, right?”

Anomic Aphasia

Anomic aphasia is typically considered the “mildest” type of aphasia. Anomia means the person has difficulty finding the right words while speaking or writing. Like all types of aphasia, anomic aphasia can be mild, moderate, severe, or very severe. Anomic aphasia may be the first diagnosis, or the person’s aphasia severity resolved over time to become anomic aphasia.

Global Aphasia

Global aphasia is a language disorder that can happen when a large area of the left hemisphere of the brain is damaged from a stroke or brain injury. Persons with global aphasia are typically (but not always) severely physically affected by the stroke. Since the motor center to speak is also located in this large area of the brain, they may also have severe apraxia of speech.

Conduction Aphasia

Conduction aphasia is a type of fluent aphasia that may not occur as frequently as other types of aphasia. Conduction aphasia can be mild, moderate, or severe. The hallmark of this aphasia is poor repetition of words/sentences, along with decreased understanding. Like Wernicke’s aphasia, their fluent speech can contain some nonsense words or words with mixed-up sounds, but less frequently. For example, saying “She wasn’t compling over againer, right?”
