Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Methylphenidate (MPH) is the most prescribed psychostimulant for children and adults with Attention-Deficit/Hyperactivity Disorder (ADHD). Meta-analyses and systematic reviews have shown that MPH is safe and efficacious in attenuating the core symptoms of ADHD, promoting overall clinical improvement. However, many patients still do not show an appropriate clinical response to the MPH treatment and there is considerable interindividual variability regarding the dose required, tolerability and response rates to MPH. Therefore, it is essential to address the clinical and genetic predictors of MPH treatment outcomes in ADHD.
