Dysarthria

11 min read

Dysarthria is a motor speech disorder that affects the muscles used for speech production. It is caused by damage to the nervous system, which can be caused by a variety of conditions, including stroke, traumatic brain injury, cerebral palsy, multiple sclerosis, and Parkinson's disease. Dysarthria can also be caused by certain medications, alcohol abuse, and other medical conditions.

Types of Dysarthria

There are several types of dysarthria, each with its own set of characteristics. These include:

  • Spastic dysarthria: This type of dysarthria is caused by damage to the upper motor neurons. It is characterized by slow, labored speech with a strained quality.
  • Flaccid dysarthria: This type of dysarthria is caused by damage to the lower motor neurons. It is characterized by weak, slurred speech with a breathy quality.
  • Ataxic dysarthria: This type of dysarthria is caused by damage to the cerebellum. It is characterized by slow, imprecise speech with a jerky quality.
  • Mixed dysarthria: This type of dysarthria is caused by damage to multiple areas of the nervous system. It is characterized by a combination of the characteristics of the other types of dysarthria.

Diagnosis and Prognosis

Dysarthria is typically diagnosed by a speech-language pathologist. The diagnosis is based on a physical examination, a review of medical history, and a speech and language evaluation. The prognosis for dysarthria depends on the underlying cause and the severity of the disorder.

Getting a Diagnosis

What is Dysarthria?

Dysarthria is a motor speech disorder that affects the muscles used for speaking. It can cause slurred or slow speech, as well as difficulty with pronunciation and volume control. Dysarthria can be caused by a variety of conditions, including stroke, brain injury, cerebral palsy, multiple sclerosis, and Parkinson’s disease.

Diagnosing Dysarthria

Diagnosing dysarthria involves a physical examination and a speech evaluation. During the physical examination, the doctor will look for signs of muscle weakness or paralysis that could be causing the speech problems. The speech evaluation will involve listening to the patient’s speech and assessing their ability to produce sounds, words, and sentences.

The doctor may also order tests to rule out other conditions that could be causing the speech problems. These tests may include a CT scan, MRI, or EEG to look for signs of brain damage or disease. Blood tests may also be ordered to check for conditions such as thyroid disease or anemia.

Treatment for Dysarthria
