IntroductionThe effect of a single dose of methylphenidate (MPH) on cognitive measures and decision-making processes was assessed in a sample of adults with ADHD and in a control sample.MethodsThirty-two adults satisfying DSM-IV criteria for ADHD and 26 healthy controls performed several cognitive tasks. Half of the participants received MPH prior to performing the tasks, and the other half received placebo in a randomized, double-blind manner.ResultsThe average digit-span test score was higher… 

Single Dose Methylphenidate Does Not Impact on Attention and Decision Making in Healthy Medical Students

In this study, MPH did not affect sustained attention and decision making in healthy young adults, did not alter the subjective perception of their mental and emotional state nor influence heart rate or blood pressure.

Methylphenidate Enhances Cognitive Performance in Adults With Poor Baseline Capacities Regardless of Attention-Deficit/Hyperactivity Disorder Diagnosis

In the sustained attention and working-memory tasks, MPH enhanced performance of both ADHD and non-ADHD adults to a similar extent compared with placebo, but the effect of MPH was not selective to ADHD adults.

Cognitive effects of methylphenidate in healthy volunteers: a review of single dose studies.

It is shown that single doses of MPH improve cognitive performance in the healthy population in the domains of working memory and speed of processing, and to a lesser extent may also improve verbal learning and memory and reasoning and problem solving.

Methylphenidate and Cognitive Performance

The effect of methylphenidate and mixed amphetamine salts on cognitive reflection: a field study.

The results indicate that MPH enhances decision-making in tasks where heuristic responses typically bias it, and should lead to increased performance on the cognitive reflection test (CRT).

MPH enhances cognitive performance in adults with poor baseline capacities regardless of ADHD diagnosis

We compare the view that the effect of Methylphenidate (MPH) is selective to individuals with Attention Deficit Hyperactivity Disorder (ADHD) with an alternative approach suggesting that its effect

Effects of methylphenidate on executive functioning in attention-deficit/hyperactivity disorder across the lifespan: a meta-regression analysis

Results indicate that effects of MPH on executive functions are independent of age in children and adults with ADHD, however, adolescent studies are lacking and needed to conclude a lack of an age-dependency across the lifespan.

Acute effects of lisdexamfetamine and D-amphetamine on social cognition and cognitive performance in a placebo-controlled study in healthy subjects

Single, high, equimolar doses of D-amphetamine and lisdexamfetamine enhanced certain aspects of cognitive performance in healthy non-sleep-deprived subjects and slightly altered aspects of social cognition.

Working Memory Capacity Predicts Effects of Methylphenidate on Reversal Learning

Investigation of effects of methylphenidate on reward and punishment learning in healthy students in a within-subject, double-blind, placebo-controlled cross-over design revealed that methylphenidates effects varied both as a function of task demands and as afunction of baseline working memory capacity.



Does Methylphenidate Improve Inhibition and Other Cognitive Abilities in Adults with Childhood-Onset ADHD?

Mph indeed ameliorates inhibition, which is the core problem of ADHD, and certain other cognitive abilities in adults with ADHD.

The Effects of Methylphenidate on Decision Making in Attention-Deficit/Hyperactivity Disorder

Acute effects of methylphenidate on neuropsychological parameters in adults with ADHD: possible relevance for therapy

Results indicate that beneficial short term effects of MPH predict longer-term effects and may thus be helpful in the decision for an off-label treatment.

Effects of methylphenidate on spatial working memory and planning in healthy young adults

The results of this study are consistent with a hypothesis that methylphenidate influences performance in two conflicting ways; enhancing executive aspects of spatial function on novel tasks but impairing previously established performance.

Methylphenidate (‘Ritalin’) can Ameliorate Abnormal Risk-Taking Behavior in the Frontal Variant of Frontotemporal Dementia

Methylphenidate was effective in ‘normalizing’ the decision-making behavior of patients, such that they became less risk taking on medication, although there were no significant effects on other aspects of cognitive function, including working memory, attentional set shifting, and reversal learning.

Neurocognitive effects of methylphenidate in adult attention-deficit/hyperactivity disorder

Adults with ADHD had a similar neurocognitive response to methylphenidate to that previously reported for childhood ADHD, providing further support for the validity of the ADHD syndrome as defined by DSM-IV and indicate possible neuroc cognitive substrates for clinical improvement with chronic methylphenidates.

Methylphenidate-induced improvements of various measures of attention in adults with Attention Deficit Hyperactivity Disorder

The present findings indicate that adults with ADHD are not differentially impaired in attentional processes but may suffer from a more global deficit of attention.

The dose-dependent effect of methylphenidate on performance, cognition and psychophysiology.

Increased autonomic arousal (heart rate, skin conductance and blood pressure) and psychophysiological (ERP) data acquired during the working memory task found supported an increase in performance and underlying brain function with methylphenidate.

Evaluation of treatment with stimulants in narcolepsy.

The literature indicates that methylphenidate, dextroamphetamine, pemoline and methamphetamine objectively improve somnolence as measured by the Multiple Sleep Latency or Maintenance of Wakefulness Tests (MSLT or MWT).

Executive and motivational processes in adolescents with Attention-Deficit-Hyperactivity Disorder (ADHD)

BackgroundThe objective of the current study was to examine performance and correlates of performance on a decision-making card task involving risky choices (Iowa Gambling Task) in adolescents with
