Study Notes
Apraxia of Speech
-
Definition: A motor speech disorder characterized by difficulty in planning and coordinating the movements needed for speech.
-
Types:
- Developmental Apraxia of Speech: Occurs in children, often without a known neurological cause.
- Acquired Apraxia of Speech: Typically results from brain damage, such as a stroke or head injury, affecting speech planning areas.
-
Key Features:
- Inconsistent speech errors (varies from one attempt to another)
- Difficulty with sound sequences (difficulty producing longer or complex phrases)
- Groping behavior (visible effort and struggle to articulate sounds)
- Errors may include substitutions, additions, or transpositions of sounds.
-
Common Causes:
- Brain lesions in the left hemisphere, particularly in Broca’s area or surrounding regions.
- Degenerative diseases (e.g., primary progressive aphasia).
-
Symptoms:
- Slowed speech rate
- Distorted phonemes
- Difficulty initiating speech
- Increased error rate with increased speech complexity
-
Diagnosis:
- Comprehensive speech evaluation by a speech-language pathologist.
- Assessment of speech production, oral motor function, and sometimes imaging studies.
-
Treatment:
- Speech therapy focusing on motor planning and coordination.
- Techniques may include repetition, modeling, and practice of specific sound patterns.
- Use of visual cues or gestures to enhance communication.
-
Prognosis:
- Varies based on the underlying cause, severity, and individual response to therapy.
- Early intervention is critical for better outcomes.
Apraxia of Speech
- A motor speech disorder affecting the planning and coordination of speech movements.
- Two types: developmental and acquired.
- Developmental occurs in children, often without a known cause.
- Acquired is usually caused by brain damage, like stroke.
- Key features include inconsistent speech errors, difficulty with sound sequences, groping behavior, and errors like substitutions, additions, or transpositions of sounds.
- Often caused by brain lesions in the left hemisphere, specifically Broca’s area or surrounding regions, as well as degenerative diseases.
- Can cause slowed speech rate, distorted sounds, difficulty initiating speech, and increased error rate with complex speech.
- Diagnosis involves a comprehensive speech evaluation by a speech-language pathologist and assessment of speech production, oral motor function, and sometimes imaging studies.
- Treatment focuses on motor planning and coordination through techniques like repetition, modeling, and practice of sound patterns.
- Visual cues and gestures are used to help communication.
- Prognosis depends on the cause, severity, and individual response to therapy, with early intervention crucial for better outcomes.
