Milestones in the history of mental retardation.

This article is an overview of notable events in the history of mental retardation covering various epoch--Antiquity, Dark and Middle Ages, Renaissance, Reformation and the ensuing centuries to the present era. Society's attitude toward mental retardation is based on its needs, expectancies and social consciousness which frequently change. The plight of individuals with mental retardation had its nadir and acme; from abject treatment less than humane to recognition as rightful members of society. Nevertheless, there are still practices that restrict integration of the mentally retarded into the mainstream of society. Hopefully, these barriers will be broken down. This, however, will be contingent upon society's deference towards the inherent dignity of all men.
