About this study

Methylphenidate (MPH) is the first-line pharmacological treatment for adults with Attention-Deficit/Hyperactivity Disorder (ADHD). Nevertheless, there is considerable interindividual variability regarding the dose required, tolerability and response rates to MPH. The aim of this study is to address the clinical and genetic predictors of MPH treatment outcomes in ADHD.
