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)
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)
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)
Six depressed patients free of recent serious suicidal ideation developed intense, violent suicidal preoccupation after 2-7 weeks of fluoxetine treatment. This state persisted for as little as 3 days to as long as 3 months after discontinuation of fluoxetine. None of these patients had ever experienced a similar state during treatment with any other(More)
OBJECTIVE The purpose of this study was to use proton magnetic resonance spectroscopy, at 4.0 T, to explore the glutamine and glutamate levels in the anterior cingulate cortex of children and adolescents with bipolar disorder (BPD; medicated and unmedicated) and healthy comparison subjects (HCSs). We hypothesized that unmedicated children with BPD would(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)
