What is the Difference Between Apraxia and Dysarthria?

🆚 Go to Comparative Table 🆚

Apraxia and dysarthria are two different motor speech disorders that affect a person's ability to produce speech properly. The main differences between them are:

  1. Cause: Apraxia is a disorder of the brain and nervous system, typically occurring after a brain injury, neurodegenerative disease, brain tumor, stroke, or head trauma. Dysarthria, on the other hand, is a result of weakness or inefficient motor movements due to muscle disorders, such as cerebral palsy, Parkinson's disease, multiple sclerosis, or other degenerative conditions.
  2. Symptoms: People with apraxia have difficulty putting words together in the correct order or 'reaching' for the correct word while speaking. In contrast, individuals with dysarthria exhibit consistent errors in speech, often due to weakness or paralysis in the muscles used for speech.
  3. Treatment: Treatment for both disorders may include improving breath support, sound production, increasing tongue and lip movement, strengthening speech muscles, and slowing the rate of speech. However, the approaches to treatment may differ, with apraxia treatment focusing on improving sound sequencing and coordination, while dysarthria treatment may involve compensatory strategies or interventions based on the severity and type of dysarthria.

In summary, apraxia is a brain-related disorder that affects the planning and organization of speech movements, while dysarthria is a muscle-related disorder that affects the execution of speech movements. Both disorders can occur in children and adults and may co-occur with other communication disorders.

    • Comparative Table: Apraxia vs Dysarthria

    Apraxia and dysarthria are both motor speech disorders that can occur in children or adults due to developmental issues, neurological changes, or injuries. They can be the result of brain trauma, such as stroke, tumor, or traumatic brain injury, but they are two distinct disorders related to speech. Here is a table highlighting the differences between apraxia and dysarthria:

    Feature Apraxia Dysarthria
    Definition A disorder where the brain struggles to effectively communicate with the muscles required for speech production. A disorder characterized by weakness or lack of control in the muscles required for speech production.
    Causes Developmental or acquired (due to brain damage). Acquired (due to brain damage) or developmental.
    Symptoms Difficulty sequencing sounds in words, producing wrong sounds. Consistent errors in speech, difficulty with muscle control and coordination.
    Diagnosis A speech-language pathologist will perform speech and language tests to rule out other types of disorders. A speech-language pathologist will perform speech and language tests and assess the severity and type of dysarthria.
    Treatment Focuses on improving motor planning of speech movements, often starting with shorter/simpler targets and progressing to longer/more complex ones. Treatment is based on severity and type of dysarthria, and may include compensatory strategies, strengthening muscles, or using augmented communication devices in severe cases.

    In summary, both apraxia and dysarthria are motor speech disorders that affect the production and control of speech. Apraxia is characterized by difficulties in sequencing sounds and producing correct sounds, while dysarthria is marked by consistent speech errors and muscle control issues.
