A double-blind, placebo-controlled, crossover study of methylphenidate (0.4 mg/kgday) and different doses of fenfluramine (1.0, 1.5, or 2.0 mg/g/day) in children with mental retardation or borderline IQ and ADHD was conducted. Parents, teachers, examiners, and physicians rated the children. There were relatively few significant drug effects by condition. When the optimal fenfluramine dose for each child was compared with placebo and methylphenidate, significant improvements occurred for fenfluramine on several parent and teacher subscales; teachers rated the children as somewhat improved with methylphenidate. The highest dose of fenfluramine produced more behavior compliance but apparently at the cost of cognitive efficiency. Most side effects (drowsiness, dizziness, anorexia) occurred with fenfluramine. Both drugs appear to be effective treatments for children with ADHD and mental retardation, although there is a possible neurotoxic action with fenfluramine. We recommend a gradual phase-in of fenfluramine dosage, up to 1.5 mg/kg/day, for most children.

We investigated whether 52 same-sex sibling pairs discordant for ever-smoking differed on psychiatric cofactors, alcohol and caffeine use, and responses to initial exposure to smoking. Ever-smokers scored significantly higher on measures of novelty seeking, depression, and childhood ADHD, and on alcohol dependence, alcohol intake, and caffeine intake. They reported significantly more pleasurable experiences, dizziness, "buzz," and relaxation upon initial exposure to smoking and significantly fewer displeasurable sensations, nausea, and cough than did nicotine-exposed, never-smoking siblings. Ever-smokers had significantly fewer years of education than their never-smoking siblings, suggesting that the concentration of smokers in lower socioeconomic strata may be partly due to downward mobility among smokers, possibly because of the observed elevation in psychiatric cofactors, which may interfere with academic performance. These findings are consistent with differences previously identified in unrelated ever- and never-smokers. Because same-sex siblings typically share a large set of common environments during childhood, our findings could be due either to genetic differences among siblings and/or (excepting educational level and responses to early exposure) to differences in adult environments.
