Official Title: PLAY GAME: Post-concussion Syndrome Affecting Youth: GABAergic Effects of Melatonin. A Randomized Double-blind Placebo-controlled Trial of MELATONIN

Brief Summary:

PURPOSE: The long-term goal of this line of research is to develop rational, biologically based evidence for the treatment of post-concussion syndrome (PCS) in children. The objective of this application is to examine the effect of melatonin on the symptoms of PCS and its neurobiology using integrated neurodiagnostic techniques in children.

OVERVIEW: PCS is a constellation of clinical symptoms including physical (i.e. headaches), cognitive (i.e. memory), and behavioral disturbances. PCS is associated with significant morbidity in the child and his/her family), and yet there are no evidence-based medical treatments available. This suggests an urgent need to develop novel treatment options to improve outcomes for children suffering from PCS. Melatonin has several relevant mechanisms of action, and neuroprotective effects. Recent research suggests that the explanations for persistent PCS symptoms may be due to alterations in neurotransmissions and neuronal circuitry, particularly involving the dorsolateral prefrontal cortex (DLPFC). Investigators have two specific aims:

  1. To determine if treatment with melatonin improves PCS in children following mild traumatic brain injury. Hypothesis: treatment of mTBI children with PCS with 3mg or 10mg of oral melatonin for 28 days will result in a decrease in PCS symptoms as compared with placebo. Effects will be dose-dependent and may be independent of sleep effects. Methods: A randomized double blind, placebo controlled trial (RCT); Outcome measure is a PCS symptom questionnaire. A subsequent RCT will then be performed using the optimal melatonin dose at a second centre.
  2. To understand the neurophysiological mechanisms of paediatric PCS and assess any resultant effects of treatment with melatonin. Methods: A case-controlled

    Detailed Summary:

    We hypothesize that the treatment of children with PCS following mTBI with 3mg or 10mg of Melatonin for 28 days will result in a decrease in PCS symptoms as compared with placebo.

    Primary research question:

    Does the treatment of children with PCS symptoms following mTBI with 3mg sublingual Melatonin or 10mg of sublingual Melatonin for 28 days result in a decrease in PCS (physical, cognitive and behavioural) symptoms as compared with placebo?

    Secondary research questions:

    Is there a dose-response relationship? Is the treatment effect independent of the effect on sleep?

    Research Design:

    This study will be conducted as a randomized, double blind, placebo-controlled superiority trial. Three parallel treatment groups will be examined with a 1:1:1 allocation: 1) sublingual placebo, 2) sublingual Melatonin 3mg, and 3) sublingual Melatonin 10mg. Groups will be allocated using a randomization sequence that will be created in variable random block sizes (multiples of 3: 3, 6, and 9) to aid in concealment of next allocation, using random number generating software. The primary endpoint is the change on the Post-Concussion Symptom Inventory Score for parent and adolescent. The design allows for dose dependent response assessment.

    Study Setting: Two academic children's hospitals in Canada Target Population: All children aged 13 to 18 years presenting to the ED of ACH and CHEO with a mTBI who remain symptomatic at 30 days post-injury.

    Intervention:

    Eligible patients will be randomized in equal

    Current Primary Outcome: Change on the Post Concussion Symptom Inventory (PCSI)-(8 - 18 years) [ Time Frame: Baseline, 4 weeks and 12 weeks ]

    The PCSI is a standardized questionnaire of 26 symptoms provides an overall rating of Post concussion symptoms. It has four specific domains: physical (including headaches), cognitive, emotional (including mood) and fatigue and high level of internal consistency, alpha=0.92. Parent and youth PCSI scores correlate. Low symptom rates are found in normative samples. The version for youth will also be recorded (PCSI-Y). Change in PCSI scores allows us to account for baseline variability and gender.


    Original Primary Outcome: Change on the Post Concussion Symptom Inventory - Adolescent (13 - 18 years) [ Time Frame: Baseline, 4 weeks and 12 weeks ]

    Current Secondary Outcome: Number of Patient's Adverse Events [ Time Frame: 1, 2, 3 and 4 weeks ]

    Original Secondary Outcome: Same as current
