What is aphasia?

How is aphasia treated?
In some instances, an individual will completely recover from aphasia without treatment. This type of “spontaneous recovery” usually occurs following a transient ischemic attack (TIA), a kind of stroke in which the blood flow to the brain is temporarily interrupted but quickly restored. In these circumstances, language abilities may return in a few hours or a few days. For most cases of aphasia, however, language recovery is not as quick or as complete. While many individuals with aphasia also experience a period of partial spontaneous recovery (in which some language abilities return over a period of a few days to a month after the brain injury), some amount of aphasia typically remains. In these instances, speech-language therapy is often helpful. Recovery usually continues over a 2-year period. Most people believe that the most effective treatment begins early in the recovery process. Some of the factors that influence the amount of improvement include the cause of the brain damage, the area of the brain that was damaged, the extent of the brain injury, and the age and health of the individual. Additional factors include motivation, handedness, and educational level.

Aphasia therapy strives to improve an individual’s ability to communicate by helping the person to use remaining abilities, to restore language abilities as much as possible, to compensate for language problems, and to learn other methods of communicating. Treatment may be offered in individual or group settings. Individual therapy focuses on the specific needs of the person. Group therapy offers the opportunity to use new communication skills in a comfortable setting. Stroke clubs, which are regional support groups formed by individuals who have had a stroke, are available in most major cities. These clubs also offer the opportunity for individuals with aphasia to try new communication skills. In addition, stroke clubs can help the individual and his or her family adjust to the life changes that accompany stroke and aphasia. Family involvement is often a crucial component of aphasia treatment so that family members can learn the best way to communicate with their loved one.

Family members are encouraged to:

Simplify language by using short, uncomplicated sentences.
Repeat the content words or write down key words to clarify meaning as needed.
Maintain a natural conversational manner appropriate for an adult.
Minimize distractions, such as a blaring radio, whenever possible.
Include the person with aphasia in conversations.
Ask for and value the opinion of the person with aphasia, especially regarding family matters.
Encourage any type of communication, whether it is speech, gesture, pointing, or drawing.
Avoid correcting the individual’s speech.
Allow the individual plenty of time to talk.
Help the individual become involved outside the home. Seek out support groups such as stroke clubs.

What are researchers investigating about aphasia?
Aphasia research is exploring new ways to evaluate and treat aphasia as well as to further understand the function of the brain. Brain imaging techniques are helping to define brain function, determine the severity of brain damage, and predict the severity of the aphasia. These procedures include PET (positron emission tomography), CT (computed tomography), and MRI ( magnetic resonance imaging) as well as the new functional magnetic resonance (fMRI), which identifies areas of the brain that are used during activities such as speaking or listening. In-depth testing of the language ability of individuals with the various aphasic syndromes is helping to design effective treatment strategies. The use of computers in aphasia treatment is also being studied. Promising new drugs administered shortly after some types of stroke are being investigated as ways to reduce the severity of aphasia.
