Speech impairment (adult)
Alternative namesLanguage impairment; Impairment of speech; Inability to speak; Aphasia; Dysarthria; Slurred speech; Dysphasia
DefinitionSpeech impairment can be any of several speech problems, particularly the following:
Dysarthria is generally apparent in daily conversation where there is difficulty expressing certain sounds or words. This condition may be caused by taking excess medications such as narcotics, phenytoin, or carbamazepine. Alcohol intoxication causes dysarthria. Some former severe alcoholics who have developed brain damage ( Korsakoff syndrome ) due to drinking may have continued problems with language, even after years of sobriety.
Degenerative neurological disorders affecting the cerebellum or brainstem can also cause dysarthria. Stroke that affects brainstem or cerebellar regions can also cause dysarthria.
Aphasia is loss of communication skills previously learned and commonly occurs following strokes or in people with brain tumors or degenerative diseases that affect the language areas of the brain. This term does not apply to children who have never developed communication skills.
In some cases of aphasia, the problem eventually resolves itself, but in others the condition is irreversible.
For dysarthria, speaking slowly is encouraged, and the use of hand gestures, when necessary, is recommended. Family and friends need to provide ample time for those afflicted with the disorder to express themselves. Medications that are causing the problem should be stopped, if possible. Use of alcohol should be minimized.
For aphasia, family members may need to provide frequent orientation reminders, such as what day it is, because disorientation and confusion often follow the onset of aphasia.
A relaxed, calm environment where external stimuli are kept to a minimum is important.
Speak in a normal tone of voice (this condition is not a hearing or emotional problem), use simple phrases to avoid misunderstanding, and don't assume that the afflicted person understands. Frustration, profanity, and depression are typical responses in people suffering from aphasia.
Provide communication aids, if possible, depending on the particular person and condition.
