How are developmental disabilities diagnosed?

If you are concerned that a member of your family may have a developmental disability—whether physical or intellectual—contact a respected behavioral healthcare organization and/or healthcare professional. First, the organization should have a qualified professional give your family member standardized intelligence and skills tests. Second, the professional should determine your family member’s strengths and weaknesses in the areas of intellectual and adaptive behavior skills, psychological and emotional considerations, physical health, and environmental factors. Finally, a trained interdisciplinary group of professionals should meet to determine what supports are needed to address each of the areas stated above.
