title: Growth of intelligence: failure and catch-up associated respectively with abuse and rescue in the syndrome of abuse dwarfism.
abstract: IQ change in association with change of environment occurred in a sample of 34 patients with a diagnosis of abuse dwarfism. Low and persistent impairment of IQ was associated with abuse. By contrast, IQ elevation was associated with rescue. Multiple regression analysis revealed that duration of rescue was the primary variable associated with IQ elevation; age and IQ level at rescue were secondary. IQ elevation was gradual and progressive over the years, as rescue was maintained. In abuse, the mean IQ was 66 (range, 36-101), and after rescue it was 90 (range 48-133). The greatest magnitude of change, from IQ 36 to 120, was in a girl between the ages of 3 yr 8 months and 13 yr 11 months.
