Developmental verbal dyspraxia (DVD), also known as childhood apraxia of speech (CAS) and developmental apraxia of speech (DAS), [1] is a condition in which an individual has problems saying sounds, syllables and words. This is not because of muscle weakness or paralysis.
Dysarthria is a motor speech disorder that results from a neurological injury. Neurodegenerative conditions like Parkinson's disease, amyotrophic lateral sclerosis, and progressive supranuclear palsy frequently transpire in association with dysarthria. [6] Some stem from central damage, while other stem from peripheral nerve damage.
Dysarthria is the reduced ability to motor plan volitional movements needed for speech production as the result of weakness/paresis and/or paralysis of the musculature of the oral mechanism needed for respiration, phonation, resonance, articulation, and/or prosody.
Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system [1] and is characterized by poor articulation of phonemes. [2] It is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words.
Developmental verbal dyspraxia (DVD), also known as childhood apraxia of speech (CAS) and developmental apraxia of speech (DAS), [3] [4] is an inability to utilize motor planning to perform movements necessary for speech during a child's language learning process. Although the causes differ between AOS and DVD, the main characteristics and ...
Fine motor planning, control and coordination are often affected. [117] Dysarthria, a speech disorder resulting from neurological damage to the motor-speech system, occurs in an estimated 31% to 88% of those with cerebral palsy. Such individuals may require AAC support for communication.
Music therapy for non-fluent aphasia is a method for treating patients who have lost the ability to speak after a stroke or accident.Non-fluent aphasia, also called expressive aphasia, is a neurological disorder that deprives patients of the ability to express language.
Flaccid dysarthria is characterized by little control over pitch and voice volume, reduced speech rate, and impaired voice quality Hypokinetic dysarthria is characterized by harsh voice quality, monotone, reduced volume and breathiness
