Methylphenidate, modafinil, and caffeine for cognitive enhancement in chess: A double-blind, randomised controlled trial.
2017
Stimulants and caffeine have been proposed for cognitive enhancement by healthy subjects. This study investigated whether performance in chess - a competitive mind game requiring highly complex cognitive skills - can be enhanced by methylphenidate, modafinil or caffeine. In a phase IV, randomized, double-blind, placebo-controlled trial, 39 male chess players received 2×200mg modafinil, 2×20mg methylphenidate, and 2×200mg caffeine or placebo in a 4×4 crossover design. They played twenty 15-minute games during two sessions against a chess program (Fritz 12; adapted to players' strength) and completed several neuropsychological tests. Marked substance effects were observed since all three subs…
Psychiatric Comorbidity at the Time of Diagnosis in Adults With ADHD: The CAT Study.
2016
Objective: The CAT ( Comorbilidad en Adultos con TDAH) study aimed to quantify and characterize the psychiatric comorbidity at the time of diagnosis of ADHD in adult outpatients. Method: Cross-sectional, multicenter, observational register of adults with ADHD diagnosed for the first time. Results: In this large sample of adult ADHD ( n = 367), psychiatric comorbidities were present in 66.2% of the sample, and were more prevalent in males and in the hyperactive-impulsive and combined subtypes. The most common comorbidities were substance use disorders (39.2%), anxiety disorders (23%), and mood disorders (18.1%). In all, 88.8% patients were prescribed pharmacological treatment for ADHD (in 9…
Does intensive multimodal treatment for maternal ADHD improve the efficacy of parent training for children with ADHD? A randomized controlled multice…
2015
Background This is the first randomized controlled multicenter trial to evaluate the effect of two treatments of maternal attention-deficit hyperactivity disorder (ADHD) on response to parent–child training targeting children's external psychopathology. Methods Mother–child dyads (n = 144; ADHD according to DSM-IV; children: 73.5% males, mean age 9.4 years) from five specialized university outpatient units in Germany were centrally randomized to multimodal maternal ADHD treatment [group psychotherapy plus open methylphenidate medication; treatment group (TG): n = 77] or to clinical management [supportive counseling without psychotherapy or psychopharmacotherapy; control group (CG): n = 67].…
Safety Profile of Methylphenidate Under Long-Term Treatment in Adult ADHD Patients – Results of the COMPAS Study
2020
Abstract Introduction The Comparison of Methylphenidate and Psychotherapy in adult ADHD Study (COMPAS) was a prospective, randomized multicenter clinical trial, comparing methylphenidate (MPH) with placebo (PLAC) in combination with cognitive behavioral group psychotherapy (GPT) or individual clinical management (CM) over the period of 1 year. Here, we report results on treatment safety. Methods MPH and PLAC were flexibly dosed. Among 433 randomized patients, adverse events (AEs) were documented and analyzed on an “as received” basis during week 0–52. Electrocardiogram data were recorded at baseline and week 24. Results Comparing 205 patients who received ≥1 dose of MPH with 209 patients wh…
Life context of pharmacological academic performance enhancement among university students – a qualitative approach
2014
Background Academic performance enhancement or cognitive enhancement (CE) via stimulant drug use has received increasing attention. The question remains, however, whether CE solely represents the use of drugs for achieving better academic or workplace results or whether CE also serves various other purposes. The aim of this study was to put the phenomenon of pharmacological academic performance enhancement via prescription and illicit (psycho-) stimulant use (Amphetamines, Methylphenidate) among university students into a broader context. Specifically, we wanted to further understand students’ experiences, the effects of use on students and other factors, such as pressure to perform in thei…
Childhood methylphenidate treatment of ADHD and response to affective stimuli
2009
Neural correlates of emotional dysregulation in attention-deficit/hyperactivity disorder (ADHD) and persisting influence of Methylphenidate (MPH) still remain insufficiently understood. Decreased activation in the subgenual cingulate and the ventral striatum were found during the perception of positive and negative affective pictures in drug-naïve males with ADHD during childhood (n=10). Males with ADHD during childhood treated with MPH (n=10) did not show any significant differences compared to healthy controls (n=10). Further prospective studies need to clarify direct and indirect mechanisms of MPH treatment that may contribute to emotional processing, which is dysfunctional in males with…
Long-term Effects of Multimodal Treatment on Adult Attention-Deficit/Hyperactivity Disorder Symptoms: Follow-up Analysis of the COMPAS Trial.
2019
Key Points Question What are the long-term results of multimodal treatment for adult attention-deficit/hyperactivity disorder (ADHD) when comparing cognitive behavioral group psychotherapy (GPT) with individual clinical management (CM) in combination with either methylphenidate or placebo? Findings In this follow-up assessment of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a multicenter randomized clinical trial, 256 adults participated in follow-up 1.5 years after the intervention ended. The severity of ADHD symptoms improved in all 4 prior treatment groups, with no significant difference found between GPT and CM, but methylphenidate was associated wit…
Effectiveness of Psychotherapy in Adult ADHD: What Do Patients Think? Results of the COMPAS Study
2017
Objective: In the multicenter study Comparison of Methylphenidate and Psychotherapy in Adult ADHD (COMPAS), the efficacy of treatments has been primarily evaluated by observer-rated symptom change. Here, we additionally analyzed the patients’ subjective evaluation of therapy effects. Method: COMPAS compared ADHD-specific group therapy with unspecific clinical management with/without concomitant pharmacotherapy in a four-armed design. Evaluation through the patients’ retrospective perspective was performed after 1 year (post-treatment) and after another 1.5 years (follow-up). Results: In respect to patients’ subjective ratings, ADHD-specific group psychotherapy outperformed unspecific manage…
The pharmacological and non-pharmacological treatment of attention deficit hyperactivity disorder in children and adolescents: A systematic review wi…
2017
Background Attention deficit hyperactivity disorder (ADHD) is one of the most commonly diagnosed psychiatric disorders in childhood. A wide variety of treatments have been used for the management of ADHD. We aimed to compare the efficacy and safety of pharmacological, psychological and complementary and alternative medicine interventions for the treatment of ADHD in children and adolescents. Methods and findings We performed a systematic review with network meta-analyses. Randomised controlled trials (≥ 3 weeks follow-up) were identified from published and unpublished sources through searches in PubMed and the Cochrane Library (up to April 7, 2016). Interventions of interest were pharmacolo…
Anti-Hypotensive Treatment and Endothelin Blockade Synergistically Antagonize Exercise Fatigue in Rats under Simulated High Altitude
2013
Rapid ascent to high altitude causes illness and fatigue, and there is a demand for effective acute treatments to alleviate such effects. We hypothesized that increased oxygen delivery to the tissue using a combination of a hypertensive agent and an endothelin receptor A antagonist drugs would limit exercise-induced fatigue at simulated high altitude. Our data showed that the combination of 0.1 mg/kg ambrisentan with either 20 mg/kg ephedrine or 10 mg/kg methylphenidate significantly improved exercise duration in rats at simulated altitude of 4,267 m, whereas the individual compounds did not. In normoxic, anesthetized rats, ephedrine alone and in combination with ambrisentan increased heart…
