Intellectual Development Disorder Basics
IDD: What Is It?
Intellectual development disorder (IDD) is a neuro-developmental disorder characterized by deficits in general intellectual functioning such as reasoning, planning, judgment, abstract thinking, academic learning and experiential learning. These may also lead to impairments in practical, social and academic functioning. The symptoms of intellectual development disorder, a relatively new disorder, formerly fell under the umbrella of “mental retardation.”
