Summary

Impulsivity, irritability and compulsivity are cross-disorder symptom domains, which affect a significant proportion of adolescents.

Predominately as part of attention deficit hyperactivity disorder (ADHD) but also as symptom domains without a diagnosis of ADHD, impulsivity and irritability cause serious burden. Furthermore, treatment options and their effects are limited.

Previous studies with different study designs assessing micronutrients for the treatment of impulsivity / ADHD in children and adults have reported positive benefits as well as a very good tolerability. However, more research is required; in particular controlled studies with adolescents, cross-disorder approaches and studies investigating long-term effects are missing.

The focus of this study is to investigate the effect of micronutrients on impulsivity, irritability and compulsivity in children and adolescents between 11 and 18 years of age with a high level of impulsivity and irritability with or without a diagnosis of attention deficit hyperactivity disorder (ADHD).

The investigators intend to include 210 children and adolescents (n=110 in Germany) with a high level of impulsivity and irritability.

The study is divided in two phases. An initial 10-week double blind, placebo-controlled treatment phase with broad-spectrum micronutrients is followed by a 10-week open-label treatment phase. The study assessments will be performed during five study visits and a follow-up visit.

Exclusion Criteria

Subject is being treated with a medication that might, in the opinion of the investigator, pose a safety risk for the subject when participating in this study
Intellectual disability (based on available IQ or the clinical opinion of the investigator, taking into account relevant psychosocial information, e.g. educational level)
Any known abnormality of mineral metabolism (e.g., Wilson's disease, haemochromatosis)
History of or present clinically relevant somatic or psychiatric acute or chronic disorder that, in the opinion of the investigator, might confound the results of tolerability/safety assessment, or prohibit the patients from completing the study, or would not be in the best interest of the patient
Subject has a documented allergy, hypersensitivity, or intolerance to any of the ingredients of the investigational product
Subject has taken any kind of food supplement containing vitamins, minerals and/or trace elements within 30 days prior to entering the study
Subject has taken another investigational product or taken part in a clinical study within 30 days prior to entering the study
