Severe distortions in the development of many basic psychological functions that are not normal for any stage in development. These distortions are manifested in sustained social impairment, speech abnormalities, and peculiar motor movements.
A child whose needs, abilities, or other characteristics vary so much from the average in mental, physical, or social areas that a greater than usual level of services is needed to facilitate the child's maximum potential development.
These are a group of conditions with onset in the developmental period. The disorders typically manifest early in development, often before the child enters grade school, and are characterized by developmental deficits that produce impairments of personal, social, academic, or occupational functioning. (From DSM-V).
The language and sounds expressed by a child at a particular maturational stage in development.
Disorders caused by nutritional imbalance, either overnutrition or undernutrition, occurring in children ages 2 to 12 years.
