There is evidence that distractibility is associated with a decreased level of serotonin. This research aims to see if giving people 5-HTP will alter their distractibility, which will form part of an initial assessment as to whether 5-HTP could be used to support people with attention problems. The study involves completing a short survey about mental health and behaviours, and if eligible, participation in an in-person study at the University of Sheffield. The in-person session involves completing some cognitive tasks to look at eye movement, taking 5-HTP or a sugar tablet with no active ingredients, and then completing the tasks again after a 90-minute wait.",[28,29,30],"Attention Deficit and Hyperactivity Disorder (ADHD)","Attention Deficit Hyperactivity Disorder in Adults","Attention Deficits",[32,33,34,35,36,37],"5-Hydroxytryptophan","Serotonin","ADHD","microsaccades","eye tracking","attention","RECRUITING","2026-08-18",{"date":41,"type":42},"2026-08-20","ACTUAL",{"date":44,"type":42},"2025-11-25",{"date":46,"type":22},"2027-06",{"name":48,"class":49},"University of Sheffield","OTHER",1,{"id":52,"slug":53,"hasResults":11,"nctId":54,"briefTitle":55,"officialTitle":56,"acronym":57,"eligibilityCriteria":58,"healthyVolunteers":16,"sex":17,"minAge":59,"maxAge":60,"enrollmentInfo":61,"targetDuration":4,"studyType":62,"phases":4,"briefSummary":63,"conditions":64,"keywords":65,"overallStatus":68,"whyStopped":4,"lastUpdateSubmitDate":69,"lastUpdatePostDateStruct":70,"startDateStruct":72,"completionDateStruct":74,"leadSponsor":76,"locationsCount":4},"100645830","eating-behaviour-and-snack-consumption-patterns-among-children-with-adhd-100645830","NCT07690033","Eating Behaviour and Snack Consumption Patterns Among Children With ADHD","Eating Behaviour and Snack Consumption Patterns Among Children With Attention Deficit Hyperactivity Disorder","ADHD children","Inclusion Criteria:\n\n* Age 6-12 years.\n* Met the diagnostic criteria for ADHD by the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5); and severity assessment by Conners Rating Scale (parent form)\n* For controls: negative ADHD assessment using DSM 5 clinical interview and Conners scale; no history of ADHD diagnosis\n\nExclusion Criteria:\n\n* ADHD symptoms due to other neurodevelopmental, psychotic, mood or organic disorders, or medication effects\n* Known neurological disease, severe chronic illness, or special diet that may alter intake\n* Use of psychotropic or appetite altering medications for ≥3 months\n* Refusal to participate","6 Years","12 Years",{"count":21,"type":22},"OBSERVATIONAL","The goal of this observational study is to learn about the effect of eating behavior and snack consumption patterns among children with ADHD.
