Developmental coordination disorder (DCD), also known as developmental motor coordination disorder, developmental dyspraxia, or simply dyspraxia (from Ancient Greek praxis 'activity'), is a neurodevelopmental disorder [1] characterized by impaired coordination of physical movements as a result of brain messages not being accurately transmitted to the body.
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.
Speaking is an act dependent on thought and timed execution of airflow and oral motor / oral placement of the lips, tongue, and jaw that can be disrupted by weakness in oral musculature or an inability to execute the motor movements needed for specific speech sound production (apraxia of speech or developmental verbal dyspraxia).
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 ...
Sensory processing disorder (SPD), formerly known as sensory integration dysfunction, is a condition in which multisensory input is not adequately processed in order to provide appropriate responses to the demands of the environment.
Specific language impairment (SLI) (the term developmental language disorder is preferred by some) [1] is diagnosed when a child's language does not develop normally and the difficulties cannot be accounted for by generally slow development, physical abnormality of the speech apparatus, autism spectrum disorder, apraxia, acquired brain damage or hearing loss.
Children with CDS seem to have more difficulty with consistently remembering things that were previously learned and make more mistakes on memory retrieval tests than do children with ADHD. They have been found to perform much worse on psychological tests involving perceptual-motor speed or hand-eye coordination and speed.
The term "protracted phonological development" is sometimes preferred when describing children's speech, to emphasize the continuing development while acknowledging the delay. A study in the United States estimated that amongst 6 year olds, 5.3% of African American children and 3.8% of White children have a speech sound disorder. [1]
