Brief Summary
The goal of the study is to use graph theory to examine how the organization of the functional brain network may be altered by the administration of methylphenidate. This effect is to be compared between methylphenidate intake and placebo intake, as well as between healthy adult males and adult males with a diagnosis of Attention Deficit Hyperactivity Disorder.

Outcome Measures
Primary Outcomes (1)
The difference in functional connectivity as measured with functional Magnetic Resonance Imaging between participants who ingested methylphenidate and those who ingested placebo.
The primary objective in the current trial is to use graph theory to examine how the organization of the functional brain network may be altered by the administration of methylphenidate. The main question we intend to answer in this study, is whether, and if so to what extent, methylphenidate affects the organization of brain networks.
After the last patient has completed the last visit, which is expected to be two years after the start of the study
Secondary Outcomes (3)
The difference in functional connectivity as measured by functional Magnetic Resonance Imaging between participants with Attention Deficit Hyperactivity Disorder and healthy controls.
After the last patient has completed the last visit, which is expected to be two years after the start of the study
The correlation of graph metrics (as a measure of functional network organization) with performance (scores) on cognitive tasks and blood levels of methylphenidate.
After the last patient has completed the last visit, which is expected to be two years after the start of the study
The correlation of whole brain cortical thickness and white matter volume as measured with Magnetic Resonance Imaging with both graph metrics as measured with functional Magnetic Resonance Imaging and scores on cognitive tests.
After the last patient has completed the last visit, which is expected to be two years after the start of the study
Study Arms (2)
Attention Deficit Hyperactivity Disorder
EXPERIMENTALAdult males with Attention Deficit Hyperactivity disorder will participate in a crossover design and receive both methylphenidate and placebo on two separate days.
Healthy adults
EXPERIMENTALHealthy male adults will participate in a crossover design and receive both methylphenidate and placebo on two separate days.
