What are Developmental Disabilities?

There are approximately 4.5 million individuals with developmental disabilities in the United States. Developmental disabilities (DD) are severe, life-long disabilities attributable to mental and/or physical impairments, manifested before age 22. 

Developmental disabilities result in substantial limitations in three or more areas of major life activities:

  • Capacity for independent living
  • Economic self-sufficiency
  • Learning
  • Mobility
  • Receptive and expressive language
  • Self-care
  • Self-direction

Examples of Developmental Disabilities:

  • Mental Retardation is the most common developmental disability, affecting 2 to 3% of the population.
  • Down syndrome
  • Autism Spectrum Disorders
  • Cerebral palsy
  • Spina Bifida
  • Fragile X Syndrome
  • Fetal Alcohol Syndrome
  • Genetic and Chromosomal Disorders

Tips on Working with People with Developmental Disabilities:

  • Smile and be friendly
  • Focus on abilities, not disabilities
  • Treat each person with a disability as a person, first – a person with likes, dislikes, and capabilities just like everyone else
  • Be positive, have a good attitude, and be patient
  • Assist by explaining what to do, rather than what not to do
  • Make instructions simple and clear
  • Speak clearly and be specific
  • Talk to and with people -- not at them
  • Establish routines and prepare people in advance for unexpected changes in routine
  • Be observant and aware
  • Establish limitations and maintain them
  • Provide opportunities for choice, decision making, and expression
  • Encourage confidence and self-esteem
