Gene-environment Interactions and Brain Functional Connectivity in Attention Deficit Hyperactivity Disorder

This study is exploring blood test or biological sample for people with adhd. Participants may complete study visits, assessments, or follow-up activities defined by the research team. Direct benefit is not guaranteed. The detailed objective is not always clearly listed in the public registry; the study team can confirm.

The study type is not clearly categorized in the public registry. Focus on the objective, required tasks, visits, any intervention, and eligibility criteria, then ask the study team to confirm.

This study may concern people with adhd; age range: From 6 Years to 18 Years. The criteria appear fairly specific, but you should not assume you are eligible. The study team must confirm diagnosis, age, exclusions, available locations, and next steps.

The public registry does not clearly describe all participation steps.

The public registry does not make the main risk category clear. Ask the study team what activities are required, what could feel uncomfortable, how safety is monitored, and what happens if you want to stop. For any mental health study, also ask who to contact if you feel worse, whether participation may affect current treatment, whether you can stop, and who confirms eligibility.

The likely practical burden appears moderate. Things to check include long follow-up or multiple visits. Ask the study team about duration, visits, possible compensation, data access, and what happens if you want to stop.

This study is sponsored by Seoul National University, which appears to be a university. If available, it can be useful to check the sponsor website, collaborators, investigator affiliation, and the official registry before deciding. HopeStage does not judge the quality of a sponsor or researcher, but helps you identify what to verify.

The registry indicates that this study is completed. It may still be useful for understanding the research, but you are unlikely to be able to join.
