Intellectual Disability (ID) – Definition and Overview:

Intellectual Disability (ID) is a neurodevelopmental disorder characterized by limitations in intellectual functioning and adaptive behavior. It begins before the age of 18 and affects a person’s ability to learn, reason, solve problems, and function independently in daily life.

      • Communication
      • Social skills
      • Personal care
      • Home living
