Dysarthria is a speech disorder. It differs from aphasia , which is a language disorder.
This condition can be caused by not being able to control and coordinate the muscles that you use to talk. This can result from:
- Brain tumor or brain trauma
- Conditions that paralyze the face or cause weakness, such as Bell’s palsy
- Degenerative brain disease, such as:
Neuromuscular disease, such as:
- Cerebral palsy
- Multiple sclerosis
- Muscular dystrophy
- Myasthenia gravis
- Alcohol or drug abuse
- Surgery or weakness on the tongue
- Structural problems such as not wearing your dentures
- Side effects of medications that act on the central nervous system
Factors that increase your chance of developing dysarthria include:
- Being at high risk for stroke
- Having a degenerative brain disease
- Having a neuromuscular disease
- Abusing alcohol or drugs
- Increased age along with poor health
Symptoms of dysarthria include:
Speech that sounds:
- Hoarse, breathy
- Slow or fast and mumbling
- Soft like whispering
- Suddenly loud
- Difficulty chewing and swallowing
You will be asked about your symptoms and medical history. A physical exam will be done, paying close attention to your:
- Ability to move your lips, tongue, and face
- Production of air flow for speech
Images may be taken of your brain. This can be done with:
- MRI scan
- CT scan
- PET scan
- Single-photon emission computed tomography (SPECT) scan
- Swallowing study, which may include x-rays and drinking a special liquid
The electrical function of your nerves or muscles may be tested. This can be done with:
- Nerve conduction study
Talk with your doctor about the best treatment plan for you. Treatment options include the following:
- Addressing the cause of dysarthria, such as stroke
Working with a speech therapist, which may include focusing on:
- Doing exercises to loosen the mouth area and strengthen the muscles for speech
- Improving how you articulate
- Learning how to speak slower
- Learning how to breath better so you can speak louder
- Working with family members to help them communicate with you
