Background: Various clinical researches have been done in Ayurveda to study the effectiveness of Ayurveda intervention in attention-deficit/hyperactivity disorder (ADHD), one of the most common neurodevelopmental disorders in pediatric population. However, to date, no comprehensive systematic review has been conducted to assess the quality of clinical trials conducted and to determine the strength and safety of Ayurveda interventions in ADHD. Materials and methods: Published randomized clinical trials (RCTs), non-RCTs, and unpublished data on Ayurveda intervention in ADHD will be searched by using electronic databases such as the Cochrane Library, Pubmed, CENTRAL, Science Direct, AYUSH research portal, and other Indian databases. It involves the hand-searching of Ayurveda journals, and PG/PhD dissertations, if available, will also be utilized. The selection of study, data extraction, and synthesis will be done independently by reviewers. Standard tools will be adopted to assess the quality of trials. Risk of bias assessment will be performed by using Cochrane tool of risk of bias for RCTs and risk of bias in non-randomized studies of interventions (ROBINS-I) tool for non-RCTs. A narrative synthesis of findings from included studies will be described by providing treatment effect size. If sufficient data are available, the meta-analysis will be performed by using Review Manager. Outcome: The proposed protocol will act as a guiding tool for reproducing the same results in a transparent manner and to provide information to healthcare practitioners and policy makers. Trial registration number: PROSPERO 2019 CRD42019129676.
