Psychopathology and mental retardation: a statistical study of 100 mentally retarded children treated at a psychiatric clinic: II. hyperactivity
I Philips and N Williams
The authors studied 100 mentally retarded children referred to a
psychiatric clinic and found that 39 were hyperactive. However, there was
no significant relationship between hyperactivity and mental retardation
(with or without psychosis) or brain damage. Comparison with a group of
nonretarded children revealed no significant difference regarding
hyperactivity, thus suggesting that the disorder is not an inevitable
concomitant of mental retardation.
