Omega-3 fatty acids in the treatment of spinal cord injury: untapped potential for therapeutic intervention?

Abstract

Omega-3 fatty acids constitute a group of fatty acids with anti-inflammatory and preventive effects against various diseases. Studies in animal models have demonstrated the preventive and therapeutic effects of omega-3 fatty acids after spinal cord injury (SCI) in reducing inflammatory reactions and promoting neuroregeneration. However, studies on the efficacy of omega-3 fatty acids in treatment and prevention after SCI seem to be questionable. This study evaluates potential reasons for omega-3 fatty acid therapy oversight in populations after SCI. Therefore, some of the reasons could cover heterogeneous patient groups in size, level of injury, quality of life assessment, time since injury, no single standardised dose, various follow-up durations and metabolic changes, often insufficient to record. Due to the difficulty of collecting cases for the study, especially in the acute phase after SCI, multicenter, coordinated studies are needed to establish the effects of omega-3 fatty acids on treatment, recovery, and disease prevention in patients after SCI. Although the present results of such studies are still inconclusive, the failure to exploit the potential properties of omega-3 fatty acids in the treatment of patients with SCI solely due to methodological difficulties should be considered a potential waste.
