What is flaccid dysarthria?
Flaccid dysarthria is a motor speech disorder resulting from damage to peripheral nervous system (cranial or spinal nerves) or lower motor neuron system. Depending on which nerves are damaged, flaccid dysarthria affects respiration, phonation, resonance, and articulation.
What are the most common types of developmental dysarthria?
The three primary types of dysarthrias seen in children are spastic, flaccid and ataxic.
- Spastic dysarthria: Speech may be slow and labored, with poor articulation.
- Flaccid dysarthria; Hypernasality with nasal air escape is the main characteristic.
What is dysarthria and ataxia?
Dysarthria is a collective name that refers to a group of movement disorders that affect the muscular control of speech, resulting in altered voice quality, speech clarity, and intelligibility. It can be caused by genetic ataxia, such as Friedreich’s ataxia (FA).
What is the difference between spastic and flaccid dysarthria?
Flaccid dysarthria results from weakness caused by lower motor neuron damage. Distinguishing features are breathy voice, short phrases, increased nasal resonance, and imprecise articulation. Spastic dysarthria is caused by spasticity resulting from bilateral UMN damage.
What are the different types of apraxia?
Different types of apraxia affect the body in slightly different ways:
- Limb-kinetic apraxia.
- Ideomotor apraxia.
- Conceptual apraxia.
- Ideational apraxia.
- Buccofacial apraxia.
- Constructional apraxia.
- Oculomotor apraxia.
- Verbal apraxia.
How do you differentiate dysarthria?
Aphasia and dysarthria are both caused by trauma to the brain, like stroke, brain injury, or a tumor. Aphasia occurs when someone has difficulty comprehending speech, while dysarthria is characterized by difficulty controlling the muscles used for speech.
Is apraxia a motor speech disorder?
Apraxia is a motor speech disorder that makes it hard to speak. It can take a lot of work to learn to say sounds and words better. Speech-language pathologists, or SLPs, can help.
