Gordon Diagnostic System and WISC-III scores for clinic-referred 6- to 16-yr.-olds (184 with ADHD Combined Type and 46 without ADHD) were analyzed to evaluate the combination of scores and cutpoints that maximized diagnostic accuracy. Using an "ADHD cutpoint" of IQ minus the GDS Composite score > or = 13, 87.8% of the children were correctly identified as(More)
Personality patterns, signs of mental impairment, mental health correlates, and psychosocial consequences were assessed in 50 patients who had obstructive sleep apnea of sufficient severity to warrant recommendation for tracheostomy. The personality patterns of sleep apnea patients were consistently those of a somatic-neurotic type, similar to typical(More)
OBJECTIVE Sleep problems were analyzed in children with ADHD (Attention-deficit hyperactivity disorder). METHODS Scales were completed by parents of 135 control children and 681 children with ADHD combined type (ADHD-C) or inattentive type (ADHD-I) with or without comorbid oppositional defiant disorder (ODD), anxiety, or depression. RESULTS Children(More)
Clinical and psychoeducational data were analyzed for 119 children ages 8 to 16 years who were evaluated in a child diagnostic clinic. A learning disability (LD) was present in 70% of the children with attention-deficit/hyperactivity disorder (ADHD), with a learning disability in written expression two times more common (65%) than a learning disability in(More)
Nonverbal IQs were greater than verbal IQs for young children (3-7 years of age) on the Stanford-Binet:IV (n = 53). However, WISC-III verbal and nonverbal IQs were similar for older children, 6-15 years of age (n = 63). Stanford-Binet:IV profiles were generally consistent for the low-IQ (< 80) and high-IQ (> or = 80) groups, with high scores on visual(More)
To understand the effect of IQ and age on ability in children with autism, psychological data were analyzed for 164 3- to 15-year-olds with autism (IQs 14-143). As age increased, so did IQ, which probably reflects both an actual increase in IQ over time and the likelihood that brighter children are diagnosed later. Early in life, 67 percent had normal motor(More)
Learning, attention, graphomotor, and processing speed scores were analyzed in 149 typical control children and 886 clinical children with normal intelligence. Nonsignificant differences were found between control children and children with anxiety, depression, and oppositional-defiant disorder. Control children performed better than children with ADHD and(More)
Sixty-nine children with attention deficit hyperactivity disorder (ADHD) underwent blind methylphenidate trials. 36 had ADHD alone (with or without a learning disability) and 33 had additional neurodevelopmental disorders. Of the children with ADHD alone, 88 per cent improved significantly on methylphenidate. This did not differ significantly from the 69(More)
Children with high-functioning autism earned above normal scores on the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) Perceptual Reasoning and Verbal Comprehension Indexes and below normal scores on the Working Memory and Processing Speed Indexes and Wechsler Individual Achievement Test-Second Edition (WIAT-II) Written Expression.

STUDY OBJECTIVES We investigated the prevalence and association of excessive daytime sleepiness (EDS) with a wide range of factors (e.g., medical complaints, obesity, objective sleep [including sleep disordered breathing], and parent-reported anxiety/depression and sleep difficulties) in a large general population sample of children. Few studies have(More)
