Developmental disability refers to a group of disabilities that begin in childhood and continue through adulthood. Some of the disabilities have physical manifestations, some have cognitive or intellectual manifestations, and some have both. For example, people with cerebral palsy, spina bifida, and hydrocephalus are all considered to have a developmental disability, but they may or may not have a cognitive disability. In general, people with an intellectual disability, such as Down syndrome, fragile X syndrome, or Fetal Alcohol Syndrome, learn more slowly than their peers. This can affect communicative ability, reasoning, and social skills. People with intellectual and cognitive disabilities may require more time to perform tasks and process information. In the past, developmental disorders included pervasive developmental disorders, but this has been redefined as Autism Spectrum Disorders, so you may want to refer to specific information for patrons that may have difficulty with communication and socialization. Many people with developmental disabilities do not have any distinguishable physical characteristics. People with intellectual and cognitive disabilities may live independently. Patrons with developmental disabilities have many of the same recreational and information needs as do all patrons. People with these types of disabilities attend mainstream colleges, work in rewarding jobs, testify in court, marry, have children, and enjoy sports and reading, among other things.
