Add-on melatonin improves quality of life in epileptic children on valproate monotherapy: a randomized, double-blind, placebo-controlled trial
Abstract
This randomized, double-blind, placebo-controlled study in epileptic children aged 3-12 years evaluated the effects of add-on melatonin administration on the quality of life of these children on sodium valproate (VPA) monotherapy using a parental questionnaire. Quality of Life in Childhood Epilepsy is a questionnaire designed to assess a variety of age-relevant domains such as physical function, emotional well-being, cognitive function, social function, behavior, and general health. Of the 31 patients, 16 randomly received add-on melatonin (MEL), whereas 15 received add-on placebo (P). The questionnaire had good internal consistency reliability, because for most of the multi-item scales Cronbach's alpha reliability exceeded 0.5 (range: 0.59-0.94). To our knowledge, this is the first study assessing quality of life in epileptic children with add-on melatonin administration in the form of a randomized, double-blind, placebo-controlled trial. The study suggests a potential use of melatonin as an adjunct to antiepileptic therapy due to its diverse spectrum of action as an antioxidant, neuroprotector, and free radical scavenger, thus offering the advantage of reducing oxidant stress and subsequent damage. The beneficial effects of melatonin on sleep, its wide safety window, and its ability to cross the blood-brain barrier have the potential to improve quality of life in pediatric epilepsy.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 31 participants or records.
