Performance on a visual sustained attention and discrimination task is associated with urinary excretion of norepineprhine metabolite in children with attention-deficit/hyperactivity disorder (AD/HD).

The degree of association between performance on a sustained attention task requiring visual discrimination and urinary excretion of catecholamine metabolites was examined in a cohort of 6- to 12-year-old children (n = 31) strictly selected and diagnosed with attention-deficit/hyperactivity disorder (AD/HD) according to DSM-IV and other strict criteria. Sustained visual attention and discrimination were measured using the Test of Variables of Attention (T.O.

Effect of maternal docosahexaenoic acid supplementation on postpartum depression and information processing.

Objective: The purpose of this study was to determine the effect of docosahexaenoic acid supplementation on plasma phospholipid docosahexaenoic acid content and indices of depression and information processing for women who breast-feed.

Study Design: Mothers who planned to breast-feed their infants were assigned randomly in a double-masked fashion to receive either docosahexaenoic acid (approximately 200 mg/d) or placebo for the first 4 months after the delivery. Major outcome variables included plasma phospholipid fatty acid patterns and scores on a self-rating questionnaire of current depression symptoms.
