is a speech disorder caused by specific or general weakness of the articulators
in the mouth: lips, tongue, soft palate, vocal folds, and diaphragm (which
controls breathing). Patients with
dysarthria may sound like their speech is slurred and difficult to understand.
They may also speak too fast or too softly to be well understood, or have poor
respiratory support or resonance of sound.
is caused by damage to the brain or nerves descending from the brain. Speech will sound different depending on
where the damage occurred in the neurological system, as different speech
systems will be affected.
another motor speech disorder that is caused by neurological damage to the
brain. It is different than dysarthria,
however, because apraxia is not caused by weakness of the oral structures. Instead, the message from the brain to the
mouth to plan the movement of each speech sound is disrupted, making it
difficult to initiate speech, or result in groping to achieve the right oral
movement to form a word. Apraxia can
occur with dysarthria and aphasia.
Regional, our speech therapy team has many years of experience evaluating and
treating motor speech disorders through use of direct training to the affected
muscles or neurological deficit, and compensations to improve intelligibility
and ease of speech production.
