Attention Deficit Hyperactivity Disorder (ADHD) affects at least 5-10% of school-age children and is associated with substantial lifelong impairment, with annual direct costs exceeding $36 billion/year in the US. Despite a voluminous empirical literature, the scientific community remains without a comprehensive model of the pathophysiology of ADHD. Further, the clinical community remains without objective biological tools capable of informing the diagnosis of ADHD for an individual or guiding clinicians in their decision-making regarding treatment.

The ADHD-200 Sample
The ADHD-200 Sample dataset is aggregated and shared in QMENTA platform. Inside the project, you can find not only the raw images but also the processed data, for your convenience. Contact us for your own processing ideas.

"The ADHD-200 Sample is a grassroots initiative, dedicated to accelerating the scientific community's understanding of the neural basis of ADHD through the implementation of open data-sharing and discovery-based science. Towards this goal, we are pleased to announce the unrestricted public release of 776 resting-state fMRI and anatomical datasets aggregated across 8 independent imaging sites, 491 of which were obtained from typically developing individuals and 285 in children and adolescents with ADHD (ages: 7-21 years old). Accompanying phenotypic information includes: diagnostic status, dimensional ADHD symptom measures, age, sex, intelligence quotient (IQ) and lifetime medication status. Preliminary quality control assessments (usable vs. questionable) based upon visual timeseries inspection are included for all resting state fMRI scans."
Official site: The ADHD-200 Sample


973 subjects are collected from the latest database of ADHD-200.

T1 and rs-fMRI images are provided.


The metadata includes site, gender, handedness, diagnosis, ADHD measure, IQ measure, medication status and quality control.
Image acquisition parameters are described in this article . It contains information about how each rs-fMRI scan was performed at each of the ADHD-200 sites
