OBJECTIVE Nonpharmacological treatments are available for attention deficit hyperactivity disorder (ADHD), although their efficacy remains uncertain. The authors undertook meta-analyses of the efficacy of dietary (restricted elimination diets, artificial food color exclusions, and free fatty acid supplementation) and psychological (cognitive training,(More)
The safety of ADHD medications is not fully known. Concerns have arisen about both a lack of contemporary-standard information about medications first licensed several decades ago, and signals of possible harm arising from more recently developed medications. These relate to both relatively minor adverse effects and extremely serious issues such as sudden(More)
STUDY OBJECTIVE To review evidence on sleep and alertness in children with attention-deficit/hyperactivity disorder (ADHD) controlling for potential confounding factors. METHODS A PubMed search. Studies using ADHD diagnostic criteria other than DSM-III-R or IV and studies not excluding or controlling for psychiatric comorbidity or medication status were(More)
STUDY OBJECTIVE To review evidence on the association between restless legs syndrome (RLS) and attention-deficit/hyperactivity disorder (ADHD), to discuss the hypothetical mechanisms underlying this association, and to consider the potential interest for common pharmacologic treatments of RLS and ADHD when co-occurring. METHOD A PubMed search. RESULTS(More)
BACKGROUND Earlier studies point to the prevalence of attention deficit hyperactivity disorder (ADHD) to be similar around the world. There is, however, a wide variety in estimates. The prevalence of ADHD in youth has never been examined in France. METHOD Starting with 18 million telephone numbers, 7,912 numbers are randomly selected. Among the 4,186(More)
OBJECTIVE To evaluate sleep and alertness and to investigate the presence of possible underlying sleep/wake disorders in children with attention-deficit/hyperactivity disorder (ADHD). METHOD After 3 nights of adaptation in a room reserved for sleep studies in the department of child psychiatry, children underwent polysomnography (PSG) followed by the(More)
OBJECTIVE To perform a meta-analysis of subjective (i.e., based on questionnaires) and objective (i.e., using polysomnography or actigraphy) studies comparing sleep in children with attention-deficit/hyperactivity disorder (ADHD) versus controls. METHOD We searched for subjective and objective sleep studies (1987-2008) in children with ADHD (diagnosed(More)
OBJECTIVE To determine the role of CSF hypocretin-1 in narcolepsy with and without cataplexy, Kleine-Levin syndrome (KLS), idiopathic and other hypersomnias, and several neurological conditions. PATIENTS 26 narcoleptic patients with cataplexy, 9 narcoleptic patients without cataplexy, 2 patients with abnormal REM-sleep-associated hypersomnia, 7 patients(More)
BACKGROUND Iron deficiency causes abnormal dopaminergic neurotransmission and may contribute to the physiopathology of attention-deficit/hyperactivity disorder (ADHD). OBJECTIVE To evaluate iron deficiency in children with ADHD vs iron deficiency in an age- and sex-matched control group. DESIGN Controlled group comparison study. SETTING Child and(More)
Recent studies suggest a possible comorbidity between Attention-Deficit/Hyperactivity Disorder (ADHD) and obesity. To gain insight into this potential association, we performed a systematic review of the literature excluding case reports, non-empirical studies, and studies not using ADHD diagnostic criteria. Empirically based evidence suggests that obese(More)
