Developmental disorders comprise a group of psychiatric conditions
originating in childhood that involve serious impairment in different areas.
There are several ways of using this term. The most narrow concept is
used in the category "Specific Disorders of Psychological Development" in
the ICD-10. These disorders comprise developmental language disorder,
learning disorders, motor disorders and autism spectrum disorders. In
broader definitions ADHD is included, and the term used is
neurodevelopmental disorders. Yet others include antisocial behavior
and schizophrenia that begins in childhood and continues through life.
However, these two latter conditions are not as stable as the other
developmental disorders, and there is not the same evidence of a shared
genetic liability.
