Few studies have described movement disorders as withdrawal symptoms during psychostimulant detoxification. Although dystonia has been reported as an uncommon adverse effect of methylphenidate treatment, it has not been described in the context of methylphenidate withdrawal. We report a case of dystonia as the main withdrawal symptom in a methylphenidate-dependent adult participating in an inpatient methylphenidate detoxification program. Although movement disorders such as dystonia are very rare adverse effects of methylphenidate withdrawal, practitioners need to be alert to this risk in order to initiate appropriate treatment...

OBJECTIVES: Previous studies have shown that serum levels of vitamin D were lower in attention deficit hyperactivity disorder (ADHD) children compared to healthy controls. The aim of the study was to determine the effect of vitamin D supplementation as adjunctive therapy to methylphenidate on symptoms of children with ADHD. METHODS: Sixty-two children aged 5-12 years with a diagnosis of ADHD based on DSM-IV criteria were randomly assigned into two groups to receive either 2000IU vitamin D or placebo in addition to methylphenidate for 8 weeks...

Methylphenidate (MPH) is used clinically to treat attention-deficit/hyperactivity disorder (ADHD) and off-label as a performance enhancing agent in healthy individuals. MPH enhances catecholamine transmission via blockade of norepinephrine (NE) and dopamine (DA) reuptake transporters. However, it is not clear how this action impacts neural circuits performing cognitive and sensorimotor functions driving performance enhancement. The dorsal lateral geniculate nucleus (dLGN) is the primary thalamic relay for visual information from the retina to the cortex and is densely innervated by NE-containing fibers from the locus coeruleus (LC), a pathway known to modulate state-dependent sensory processing...

PURPOSE: This study aims to investigate the short-term efficacy and tolerability of immediate-release methylphenidate (IR-MPH) in children with a history of traumatic brain injury (TBI). METHODS: Twenty children with TBI (mean age: 12.7±3.1years) who had clinically significant attention deficit and/or hyperactivity-impulsivity symptoms and twenty children with primary Attention Deficit Hyperactivity Disorder (ADHD) (mean age: 12.3±3.05years) were included. Study measures, which included the Turgay DSM-IV based ADHD rating Scale (T-DSM-IV-S), Conners' Parent Rating Scale (CPRS), Conners' Teacher Rating Scale (CTRS-R) and Clinical Global Impression-Improvement Scale (CGI-I), were completed at the baseline for both of the groups...

OBJECTIVES: Parent rating scales are commonly used to evaluate change in clinical trials. Despite advantages, these measures may not capture parental impression of the child's most salient problems. We examine the use of parent target problems (PTPs) in a randomized trial of methylphenidate (MPH) in children with autism spectrum disorder and symptoms of attention-deficit/hyperactivity disorder. METHODS: This multisite, 4-week, randomized crossover trial compared three dose levels (low, medium, and high) of MPH with placebo...

Methylphenidate (MPD) is a widely prescribed psychostimulants used for the treatment of attention deficit hyperactive disorder (ADHD). Unlike the psychostimulants cocaine and amphetamine, MPD does not exhibit direct actions on the serotonin transporter, however there is evidence suggesting that the therapeutic effects of MPD may be mediated in part by alterations in serotonin transmission. This study aimed to investigate the role of the dorsal raphe (DR) nucleus, one of the major sources of serotonergic innervation in the mammalian brain, in the response to MPD exposure...

BACKGROUND: Self-help parenting interventions have been shown to be effective in the management of children with attention-deficit/hyperactivity disorder (ADHD) and may be useful when there are barriers to face-to-face therapist-led parent trainings. Previous studies indicate that behavioral interventions might be a useful adjunct to medication in children with residual ADHD symptoms, and regarding comorbid oppositional symptoms and multiple domains of functional impairment. In the present study, we examined whether a telephone-assisted self-help (TASH) parenting behavioral intervention (written materials plus telephone counseling) enhanced the effects of methylphenidate treatment in children with ADHD...

The purpose of this multicenter, prospective, randomized, placebo-controlled study was to evaluate and compare the efficacy of two cognitive rehabilitation interventions (Memory and Attention Adaptation Training (MAAT) and Attention Builders Training (ABT)), with and without pharmacologic enhancement (ie, with methylphenidate (MPH) or placebo), for treating persistent cognitive problems after traumatic brain injury (TBI). Adults with a history of TBI at least four months prior to study enrollment with either objective cognitive deficits or subjective cognitive complaints were randomized to receive MPH or placebo and MAAT or ABT, yielding four treatment combinations: MAAT/MPH (N=17), ABT/MPH (N=19), MAAT/placebo (N=17), and ABT/placebo (N=18)...

The association between ADHD and allergy remains controversial. Our previous findings suggest that nerve growth factor may link the nervous and immune systems. The primary objective of this study was to determine if a combination of cetirizine + methylphenidate is effective in children with comorbid ADHD and allergic rhinitis. We also examined the role of nerve growth factor in these comorbidities. Our randomized, double-blind, placebo-controlled, crossover study enrolled 38 children diagnosed with comorbid ADHD and allergy using cetirizine (n = 12), sustained-release methylphenidate (n = 12), or cetirizine + methylphenidate (n = 14)...

The 5-HT1A/1B-receptor agonist eltoprazine has a behavioral drug signature that resembles that of a variety of psychostimulant drugs, despite the differences in receptor binding profile. These psychostimulants are effective in treating impulsivity disorders, most likely because they increase norepinephrine (NE) and dopamine (DA) levels in the prefrontal cortex. Both amphetamine and methylphenidate, however, also increase dopamine levels in the nucleus accumbens (NAc), which has a significant role in motivation, pleasure, and reward...

Central hypersomnias principally involves type 1 narcolepsy (NT1), type 2 narcolepsy (NT2) and idiopathic hypersomnia (IH). Despite great progress made in understanding the physiopathology of NT1 with low cerebrospinal fluid hypocretin-1 levels, current treatment remains symptomatic. The same applies to NT2 and IH, for which the physiopathology is still largely unknown. Controlling excessive daytime sleepiness (EDS), cataplexy, hypnagogic hallucinations, sleep paralysis and disturbed night-time sleep are key therapeutic targets in NT1...

OBJECTIVES: ADHD is one of the most significant diagnostic units in child and adolescent psychiatry. The occurrence in children is 5-6% and 50-80% continued to adult age. The presence of individual genes (polymorphism) on particular symptoms and processes in ADHD are not known. It is estimated that ADHD symptoms are up to 80% to genetic. The higher density of resultant DAT 1 protein was observed in ADHD patients in comparison with controls. The question was if DAT 1 10/10 predicted bad prognoses in long term therapy...

The psychostimulant, methylphenidate (MPD), is the first line treatment as a pharmacotherapy to treat behavioral disorders such as attention deficit hyperactivity disorder (ADHD). MPD is commonly misused in non-ADHD (normal) youth and young adults both as a recreational drug and for cognitive enhancing effects to improve their grades. MPD is known to act on the reward circuit; including the caudate nucleus (CN). The CN is comprised of medium spiny neurons containing largely dopamine (DA) D1 and D2 receptors...
