A survey of psychotropic medication in mental retardation facilities.

A survey of psychotropic drug usage by questionnaires was conducted at 5 regional residential centers for the mentally subnormal in Eastern Ontario, Canada. Of the 2238 residents studied, 42% were given psychotropics, 27% anticonvulsants, and 11% a combination of both. Prolonged medication and polypharmacy were observed in all facilities. The therapeutic responses to psychotropic medication were generally poor, especially among the disturbed epileptics who had received psychotropic and anticonvulsant simultaneously. It is estimated that between one-half to two-thirds of those on psychotropics were given the agents too liberally.
