Neurodevelopmental Disorders
- A group of conditions with onset in the developmental period(often before the child enters
grade school)
- Frequently co-occur
Intellectual Disabilities
------------------------------------------------------------------------------
1. Intellectual Disabilities
- Characterized by deficits in general mental abilities such as reasoning, problem solving,
planning, abstract thinking, judgment, academic learning, and learning from experience
- Characterized by an intelligence quotient ( IQ ) score below 70 as well as deficits in two or
more adaptive behaviors that affect everyday life. These characteristics became apparent in
childhood or adolescence.
- can be either syndromic (the intellectual deficits are associated with other medical and
behavioral signs and symptoms) or non-syndromic (the intellectual deficits appear without
any other abnormalities).
Criteria:
a) deficits in general mental abilities,
b) significant limitations in one or more areas of adaptive behavior (e.g.,
communication, self-help skills, interpersonal skills) across multiple environments,
and
c) evidence that the limitations became apparent in childhood or adolescence.
Severity Level
● Mild - IQ 52–69
- Intermittent: Occasional support needed
● Moderate - IQ 36–51
- Limited: Support such as a day program in a sheltered workshop
● Severe - IQ 20–35
- Daily, ongoing support
● Profound - IQ 19 or below
- High level of support for all activities of daily living, possibly including extensive
nursing care
