Originally, the common word dumb or dumbness used to mean "unable to speak". Unfortunately this was taken over to mean "unwilling to speak". So people prefer "muteness". "Dumb" is a much commoner word, and could be preferred in contexts where it would not be misunderstood.
Cause (eteliology)[change | change source]
Adults who previously had speech and then became unable to speak: this may be due to disease, injury, damage or surgery affecting areas of the brain needed for speech. Loss of speech in adults may occur, but rarely, for psychological reasons. Damage (however caused) to the parts of the brain needed for speech is called aphasia.
Action[change | change source]
Treatment or management of muteness depends on what has caused the absence of speech. When there is an absence of speech, a speech assessment is strongly recommended to determine cause and treatment. Treatment of absence of speech is possible in a variety of cases. If the absence of speech is determined to be a permanent condition, a range of assistive and augmentative communication devices are available to aid communication.
Speech-generating devices help people with speech deficiencies.
