Omega-3 Fatty Acids as an Adjunctive Therapy for Stimulants in Children With ADHD

Study Overview
=================
Brief Summary
-----------------
Multiple forms of Omega-3 Fatty acids have been used to investigate the role of this food supplement in children with Attention Deficit Hyperactivity Disorder (ADHD). No clear evidence for their role in this disorder is yet available. We will conduct a prospective, randomized, double blind, placebo controlled trial to obtain significant results regarding this question.

Detailed Description
-----------------
A total of 30-150 patients or more between the ages of 6 and 15 years old with diagnosis of ADHD according to the DSM-IV and on current treatment with stimulants recruited from CAOS-MMC and the Developmental Center will be evaluated by a child psychiatrist or a resident under supervision of a child psychiatrist to make sure that the diagnosis is correct. Every child will have a Conners rating scale filled out by the parents and teachers on admission to the study. The evaluators will also fill out a Clinical Global Impression scale (CGI). The patients will be divided in 2 groups. One group of 15 children will be randomized to continue taking the usual dose of stimulants plus placebo (corn oil), which will be given to the patients by MMC's pharmacy. A second group of 15 patients will be randomized to receive the usual dose of stimulant plus Lovaza (prescription Omega-3 fatty acids) at a dose of 1800 mg daily. Both groups will be initially treated for a period of 8 weeks. The patients will be re-evaluated by the investigators on week 2, 4, 6 and 8 of the study and on each evaluation the parents and teachers will fill out a Conners rating scale. The ratings of the Conners rating scales filled for each patient will be analyzed and compared to the initial evaluation after week 8. The evaluators will also do a CGI score for every visit. Patients that improve will be taken off the stimulants and will continue further treatment with the adjunctive therapy for a total of 4 more weeks, during this period of time they will be re-evaluated on weeks 9, 10 and 12 and Conners scales will also be filled out by the parents. Patients who do not improve will be switched to the opposite treatment modality and will be evaluated on weeks 9, 10 and 12 also having Conners scales filled out by their parents. If any of the patients in this group improve after the switch, they will be taken off stimulants and they will be evaluated on weeks 13, 14 and 16 of the study arm. The study will be supported by GlaxoSmithKline. This pharmaceutical company will provide the capsules and the placebo.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Conners Rating Scale for assessment of ADHD characteristics | Conners Rating Scales is designed to provide an overview of child and adolescent concerns and disorders, including ADHD. The survey for parents contains 80 items and 59 items for teachers. Scoring is based on a response about specific aspects of child behavior, with a low cumulative score showing less likelihood of a specific disorder. The cumulative score is called a T-score. T-scores have a mean of 50 and a standard deviation of 10. These can be converted to percentile scores. T-scores above 60 are cause for concern and have interpretive value. Interpretable scores range from a low T-score of 61 (mildly atypical) to above 70 (markedly atypical). | 16 WEEKS | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinical Global Impression - Severity Scale (CGI-S) | The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. The CGI-Severity (CGI-S) asks the clinician one question: Considering your total clinical experience with this particular population, how mentally ill is the patient at this time? which is rated on the following seven-point scale: 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill patients. | 16 WEEKS |
