Abstract. A 10-week study was conducted in which all food was provided for the families of 24 hyperactive preschool-aged boys whose parents reported the existence of sleep problems or physical signs and symptoms. A within-subject crossover design was used, and the study was divided into three periods: a baseline period of 3 weeks, a placebo-control period of 3 weeks, and an experimental diet period of 4 weeks. The experimental diet was broader than those studied previously in that it eliminated not only artificial colors and flavors but also chocolate, monosodium glutamate, preservatives, caffeine, and any substance that families reported might affect their specific child. The diet was also low in simple sugars, and it was dairy free if the family reported a history of possible problems with cow's milk. According to the parental report, more than half of the subjects exhibited a reliable improvement in behavior and negligible placebo effects. In addition, several nonbehavioral variables tended to improve while the children received the experimental diet, particularly halitosis, night awakenings, and latency to sleep onset.

Abstract. There is evidence from a number of studies that various forms of reading disability are inherited. The familial patterns of one specific type of reading disability that occurs together with impaired coordination and balance were evaluated. Ten reading-disabled children with these motor problems, ten children with only reading problems, and ten control children without reading disabilities were examined along with their siblings and parents. The control children were matched to the reading-disabled children for age, sex, and family socioeconomic status. A high prevalence of reading and motor problems was found in the relatives of the children with reading disability and motor problems, whereas a high prevalence of only reading problems was found in the relatives of the children with only reading disability. There were no differences among the three groups of children or their siblings on number of pregnancy and birth complications or prevalence of attention deficit disorder. It was concluded that reading disability with motor problems may be an inherited type of reading disability, distinct from reading disability without motor problems, which is also inherited.

Abstract. In spite of inadequate laboratory demonstrations of sleep problems in children with attention deficit disorder with hyperactivity, the belief persists that such problems exist. Sleep restlessness is, in fact, one of the criteria in the Diagnostic and Statistical Manual of Mental Disorders, ed 3, definition of attention deficit disorder with hyperactivity, and sleep problems are listed on two major checklists often used for describing the symptoms of this disorder. In a series of three studies, sleep problems were investigated in preschool-aged children with attention deficit disorder relative to control children without the disorder. Results of the first two studies demonstrated clearly that parents of hyperactive children considered their children to have many more sleep problems than did parents of the control children. Parental daily documentation, which is less likely to be affected by reporting bias, was used in the third study. Although the results of the third study supported the finding! of increased frequency of night wakings in these children, there was no difference in total sleep time or sleep onset latency between the two groups. Two other significant group differences (enuresis and night sweats) were primarily due to subgroups of children with attention deficit disorder and hyperactivity. The greater number of sleep wakings, which disrupt parents' sleep, may be responsible for the clinical reports that these children are poor sleepers. [ABSTRACT FROM AUTHOR]
