Types of Aphasia

There are many different classification systems for aphasia and many different types of aphasia within each system. Some systems are based primarily on the location of the lesion, while others are based solely on the person's behavior. One system adopted by the National Aphasia Association divides aphasia into two broad categories: fluent and non-fluent aphasia.

People with fluent aphasia have problems understanding spoken and written language. This type is also known as sensory, posterior, or Wernicke's aphasia.

People with non-fluent aphasia have difficulty communicating orally and in writing. This type of aphasia is also called motor, anterior, or Broca's aphasia. Within the non-fluent category is the most severe type, called global aphasia. People with this type have difficulty both expressing and understanding written and oral communication.
