Causes

A developmental disability is not a disease or a mental illness. It is not contagious. It is not “curable.” There are many potential causes of developmental disabilities including genetic factors, prenatal illnesses and issues, childhood illnesses and injuries, and environmental factors. In 40 percent of diagnosed cases, the cause is unknown.
