Clinical Trial Summary

The goal of this clinical trial is to test omega-3 fatty acid supplementation as a treatment in adolescents with a concussion. The main questions it aims to answer are:

• Does supplementing with omega-3 fatty acids improve time to recovery following sport related concussion.

• Does supplementing with omega-3 fatty acids improve health related quality of life following concussion.

• Does supplementing with omega-3 fatty acids change post-concussion symptoms following concussion.

• Does supplementing with omega-3 fatty acids change saliva concentrations of interleukin-6 following concussion.

• Does supplementing with omega-3 fatty acids change saliva concentrations of cortisol following concussion.

Participants will be randomized to receive either an omega-3 supplement or placebo after they have been diagnosed with a concussion. Researchers will compare the omega-3 supplement group and placebo group to see if omega-3 fatty acids, consumed as a treatment, can improve time to recovery, health related quality of life and symptom burden, and whether omega-3 fatty acids alter interleukin-6 and cortisol concentrations in saliva following a concussion.

Description:

Following mild traumatic brain injury, a neurometabolic cascade occurs with concurrent neuronal disruptions, metabolic changes, excitotoxicity, and changes in cerebral blood flow. Omega-3 fatty acids have been postulated as a possible nutritional supplement which could aid in recovery following a concussion. The omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are derived from alpha-linolenic acid (ALA) which is an essential fatty acid. DHA is present at high concentrations in neuronal cells and contributes to the regulation of cell membranes, neurotransmitter release, neurogenesis, and neuroinflammation. EPA is converted to E-series resolvins which act in an anti-inflammatory manner.

Pre-clinical research supports the potential benefits of omega-3 fatty acids following a TBI. There has recently been one pilot study in human adolescents which also supports the need for large randomized controlled trials to fully understand the impact omega-3 fatty acids may have on recovery following concussion. The current evidence suggests that omega-3 supplementation may ameliorate neuroinflammation and neuronal apoptosis, and decrease reactive oxygen species associated with TBI. It has been suggested that following TBI, omega-3 supplementation may improve neural plasticity and signaling related molecules which can improve cognitive function following TBI.

Based on these previous mentioned studies it appears that omega-3 fatty acids could potentially benefit those recovering from a concussion. However, to date there have not been any appropriately powered randomized controlled trials evaluating the efficacy of omega-3 supplementation following sport related concussion.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to clinical recovery	Time to clinical recovery will be determined by the patients treating physician. This will be defined as: 1) symptoms have returned to baseline or resolved, 2) normal medical examination, 3) tolerating school full-time without symptoms, and 4) tolerating appropriate return to play steps and are cleared to participate in full sport activities.	Maximum of 6 weeks
Secondary	Pediatric Quality of Life Inventory (Version 4.0) Teen Report	Participants will complete the paediatric quality of life inventory (https://www.pedsql.org/index.html) each week until the participant is determined to be clinically recovered or have not recovered by 6 weeks. Scale minimum score is 0 and maximum is 52. Higher scores mean worse outcome.	Maximum of 6 weeks
Secondary	Pediatric Quality of Life Inventory (Version 4.0) Parents Report	Parent/guardian will complete the paediatric quality of life inventory (https://www.pedsql.org/index.html) each week until the participant is determined to be clinically recovered or have not recovered by 6 weeks. Scale minimum score is 0 and maximum is 52. Higher scores mean worse outcome.	Maximum of 6 weeks
Secondary	Sport Concussion Assessment Tool - 5 Symptom Evaluation	Participants will report their symptoms using the post-concussion symptom scale ((PCSS; version from the Sport Concussion Assessment Tool-5) each week until they are determined to be clinically recovered or have not recovered by 6 weeks. Scale minimum score is 0 and maximum is 132. Higher scores mean worse outcome.	Maximum of 6 weeks
Secondary	Interleukin-6	Interleukin-6 will be analyzed via enzyme-linked immunosorbent assay (ELISA) to determine changes in inflammatory status.	Maximum of 6 weeks
Secondary	Cortisol	Cortisol will be analyzed via enzyme-linked immunosorbent assay (ELISA) to determine changes in stress status.	Maximum of 6 weeks
