Attention-deficit/hyperactivity disorder is a highly heritable and prevalent neuropsychiatric disorder estimated to affect 6% of school-age children. Its clinical hallmarks are inattention, hyperactivity and impulsivity, which often respond substantially to treatment with methylphenidate or dextroamphetamine. Etiological theories suggest a deficit in(More)
OBJECTIVE To precisely describe movement abnormalities in seated children with attention-deficit hyperactivity disorder (ADHD) while they were engaged in a continuous performance task (CPT). METHOD Diagnoses were made by using structured interviews (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic Version) and(More)
The authors investigated the hypothesis that early abuse might affect the development of the limbic system. During initial psychiatric evaluation, 253 outpatients completed a self-report scale, the Limbic System Checklist-33 (LSCL-33), designed to measure somatic, sensory, behavioral, and memory symptoms suggestive of temporal lobe epilepsy, along with a(More)
This retrospective study examined the association between abuse history and neurological abnormalities in 115 consecutive patients admitted to a child and adolescent psychiatric inpatient unit. Increased electrophysiological abnormalities were found in abused patients compared with non-abused patients (54.4% vs. 26.9%, P = 0.021), predominantly in the left(More)
The objectives of this study were to investigate cortical development and hemispheric asymmetry in abused children. Fifteen hospitalized children (mean age 10.7 +/- 2.5 years) with severe physical or sexual abuse and 15 normal children (10.1 +/- 3.1 years) were studied with quantitative EEG. Abused children had higher levels of left hemisphere coherence and(More)
BACKGROUND Previous studies hypothesized that seasonal affective disorder (SAD) was caused by a circadian rhythm abnormality. The purpose of this study was to ascertain whether rest-activity rhythms were phase delayed, diminished in amplitude, or more poorly entrained to the 24-hour day. METHOD Twenty healthy adult controls and 25 outpatients meeting(More)
OBJECTIVE Previous studies have suggested that sleep disturbance may be the "hallmark of posttraumatic stress disorder," although several investigations have failed to find evidence for sleep disruption. The purpose of this study was to determine whether intense averse stimulation during early development, in the form of physical and/or sexual abuse, led to(More)
OBJECTIVE Published dosing guidelines for treatment of Seasonal Affective Disorder (SAD) refer to photopic lux, which is not appropriate for short-wavelength light. Short wavelengths are most potent for many non-visual responses to light. If SAD therapy were similarly mediated, standards utilizing lux risk overestimating necessary dose. We investigated(More)
