BACKGROUND Evidence suggests that children living in single-parent or step-parent households are more likely than children in households with 2 biological parents to be prescribed methylphenidate. I conducted a study of prospective data to investigate parental divorce as a predictor of methylphenidate use. METHODS I used data for children who participated in the National Longitudinal Survey o...
a recent randomized clinical trial showed buspirone efficacy in the treatment of attention-deficit/hyperactivity disorder (adhd) in children. however, results from a recent multi-site controlled clinical trial of transdermal buspirone failed to separate it from placebo in a large sample of children with adhd. therefore, due to these inconsistent findings, this study was designed to assess the e...
BACKGROUND Our review of the scientific literature focused on an analysis of studies describing instances of methylphenidate treatment leading (or not) to behavioral changes in the pediatric, adolescent, and adult populations. MATERIALS AND METHODS We conducted a literature search in PubMed, Medline, and Google using the keywords "methylphenidate", "behavioral changes", "adverse effects", and...
Multidomain assessment may enhance the diagnosis of cognitive impairment in children with attention-deficit hyperactivity disorder (ADHD). A set of novel Web-enabled computerized tests has recently been shown to be valid for identifying mild cognitive impairment and characterizing the cognitive profile associated with various disorders. It was anticipated that these tests would be well suited f...
OBJECTIVE The use of methylphenidate to treat attention-deficit/hyperactivity disorder has risen dramatically in Western countries, and it is increasingly used by adults, including women of childbearing age. Very little is known about potential hazards of in utero exposure to methylphenidate. We conducted this study to estimate the risk of major congenital malformations following first-trimeste...
CONTEXT Attention-deficit/hyperactivity disorder (ADHD) is the most prevalent psychiatric disorder of childhood. There is considerable evidence that brain dopamine is involved in ADHD, but it is unclear whether dopamine activity is enhanced or depressed. OBJECTIVE To test the hypotheses that striatal dopamine activity is depressed in ADHD and that this contributes to symptoms of inattention. ...
Patients: A series of 16 patients diagnosed with traumatic brain injury (n = 12) and subarachnoid hemorrhage (n = 4) were followed before and after taking methylphenidate, as a part of treatment for clinically identified atten-tional deficit. Results: The introduction of methylphenidate correlated with an improvement in processing speed loss, divided attention loss, and selective attention loss...
Sir,—Muscular spasticity and tremor occurs during recovery from general anaesthesia, especially following halothane (Dawkins, 1961), and may be associated with hypoxaemia (Jones and McLaren, 1965). This condition may be prevented or controlled by methylphenidate (Brichard and Johnstone, 1970). However, this drug is an unreliable analgesic, may provoke adrenergic overactivity (Brichard and Johns...
BACKGROUND Despite the persistence of attention-deficit/hyperactivity disorder (ADHD) into adolescence, little is known about the efficacy and tolerability of stimulant medications in this age group. OBJECTIVE To report the results of a multisite controlled study among adolescents with ADHD evaluating the efficacy and tolerability of osmotic-release oral system (OROS) methylphenidate. DESIG...
Abstract Introduction Both modafinil and methylphenidate are frequently utilized for maintenance of wakefulness in narcolepsy other sleep disorders. have been demonstrated to affect dopamine transporter, leading an increase extracellular dopamine. Subsequent functional connectivity changes between nucleus accumbens pallidum noted. Animal studies demonstrate neuronal activity with accumbens. To ...
