BACKGROUND The purpose of this multicenter Spanish study was to evaluate the response to immediate-release methylphenidate by children and adults diagnosed with attention-deficit/hyperactivity disorder (ADHD), as well as to obtain information on current therapy patterns and safety characteristics. METHODS This multicenter, observational, retrospective, noninterventional study included 730 pat...
BACKGROUND Methylphenidate and atomoxetine are commonly prescribed for treating attention deficit hyperactivity disorder (ADHD). However, their therapeutic neural mechanisms remain unclear. METHOD After baseline evaluation including cognitive testing of the Cambridge Neuropsychological Test Automated Battery (CANTAB), drug-naive children with ADHD (n = 46), aged 7-17 years, were randomly assi...
A growing body of literature has examined the cognitive effects of immediate-release methylphenidate in children with attention-deficit/hyperactivity disorder (ADHD). However, a clear understanding of the types and magnitude of such effects are difficult to discern from such a large and varied collection of published reports. This review evaluated a total of 40 relevant placebo-controlled studi...
Background: Deficits characteristic of Attention Deficit/Hyperactivity Disorder (ADHD), including poor attention and inhibitory control, are at least partially alleviated by factors that increase engagement of attention, suggesting a hypodopaminergic reward deficit. Lapses of attention are associated with attenuated deactivation of the Default Mode Network (DMN), a distributed brain system norm...
Methylphenidate remains the mainstay of pharmacological management in attention deficit hyperactivity disorder (ADHD). Despite having been available for over half a century, methylphenidates original formulation has been modified with the main purpose of extending its duration of action. This article will present a brief review of how these new formulations vary and how these should be selected...
Attention Deficit/Hyperactivity Disorder (ADHD) is a well-recognized behavioral disorder estimated to affect 2-9% of school-age children (1,2). Historically, ADHD was not thought to continue beyond adolescence; however, long term followup studies in the 1980s showed that disabling core symptoms persist into adulthood in 11-50% of cases. Hence, 1-3% of adults may currently have symptoms of ADHD,...
Methylphenidate hydrochloride (Ritalin) is the drug of choice for attention deficit hyperactivity disorder (ADHD). However, an association of Ritalin with glaucoma has been reported. We report a case of Ritalin-associated cataract and glaucoma. A 10-year-old boy was diagnosed with ADHD and had received methylphenidate hydrochloride, 60 mg/day for 2 years. He presented with blurred vision. Best-...
BACKGROUND Attention deficit/hyperactivity disorder has been shown to affect working memory, and fMRI studies in children and adolescents with attention deficit/hyperactivity disorder report hypoactivation in task-related attentional networks. However, studies with adult attention deficit/hyperactivity disorder patients addressing this issue as well as the effects of clinically valid methylphen...
BACKGROUND Psychostimulant medication, most commonly the catecholamine agonist methylphenidate, is the most effective treatment for attention-deficit/hyperactivity disorder (ADHD). However, relatively little is known on the mechanisms of action. Acute effects on brain function can elucidate underlying neurocognitive effects. We tested methylphenidate effects relative to placebo in functional ma...
