A developmental disorder is any condition that appears at some stage in a child's development and delays the development of one or more psychological functions, such as language skill. Developmental disorders include psychological and physical disorders, for example autism or dyslexia. Developmental disorders are an impairment in the normal development of motor or cognitive skills that are developed before age 22. They are usually expected to continue indefinitely, and there usually is no cure.
Developmental disorders can be grouped into specific developmental disorder and pervasive developmental disorders.
They are sometimes equated with developmental disabilities.

Famous quotes containing the word disorder:
“Both of us felt more anxiety about the South—about the colored people especially—than about anything else sinister in the result. My hope of a sound currency will somehow be realized; civil service reform will be delayed; but the great injury is in the South. There the Amendments will be nullified, disorder will continue, prosperity to both whites and colored people will be pushed off for years.”
—Rutherford Birchard Hayes (1822–1893)
