Primary Outcome Measures

Name	Time	Method
Main Objective: The main goal is to perform this pilot study where we try to duplicate some of the results of other recent experiments and show we can do at least as well, preferably better. Furthermore, using a CNS drug enhancer, we intend to measure the effect of a common AD/HD treatment on the EEG of AD/HD patients, thus hoping to get a high degree of separation of individuals belonging to various subgroups of AD/HD. The main objective of using a CNS drug enhancer is to determine if there are any features of the EEG that can predict success of treatment for a given individual who has been diagnosed with AD/HD.;Secondary Objective: ;Primary end point(s): The endpoint of the study is to have 120 EEG measurements from two groups of 40 boys. 80 EEGs from a group of 40 boys who have recently been diagnosed with ADHD and are between 6 and 8 years of age and 40 EEGs from another group of 40 healthy age matched boys. The clinical group is measured before and after Ritalin® administration.
