Thinning of the cerebral cortex during development: a dimension of ADHD.

摘要

One of the conundrums in developmental child psychopathology stems from the fact that most of the denning clinical signs of psychiatric disorders also occur in normally developing children. This phenomenon has fueled controversy regarding the boundaries that define deviance and psychopathology, the point at which their joints lie, and where to carve them. Ambiguity regarding the limits between normalcy and pathology is not trivial, since it has been seized upon to call into question the whole enterprise of classifying psychiatric disorders and to claim that the nomenclature erroneously medicalizes normal variations of children's behavior.
