Dysarthria, (Motor Speech Disorder) A Simple Guide To The Condition, Diagnosis, Treatment And Related Conditions

Dysarthria is a motor speech disorder in which the patient finds difficulty saying words because of disorders with the muscles that assist the patient to talk. Dysarthria occurs from impaired movement of the muscles utilized for speech production, such as the lips, tongue, vocal folds, and diaphragm. The type and severity of dysarthria are dependent on which area of the nervous system is involved.
The muscles used for speech are managed by the brain and nervous system. Dysarthria can form if either of these is injured in some way. Dysarthria can either be:1. DevelopmentalIt happens as a result of brain damage before or during birth, such as in cerebral palsy2. AcquiredIt happens as the result of brain changes later in life, such as damage caused by a stroke, head injury or brain tumor, or a progressive disorder such as Parkinson's diseaseDysarthria in children is normally developmental while dysarthria in adults is often acquired, even though both types can affect people of any age.

Tests that may be done if the cause of the dysarthria is not known are:1. Blood tests for toxins or vitamin levels2. Imaging tests, such as an MRI or CT scan of the brain or neck3. Nerve conduction studies and electromyogram to check the electrical function of the nerves or muscles4.
Swallowing study, which may include x-rays and drinking a special liquidThe speech therapist may also want to evaluate the movement of the muscles in the mouth and voice box (larynx), and may wish to make a recording of the voice.
