Resveratrol as a therapeutic choice for traumatic brain injury: An insight into its molecular mechanism of action

Abstract

Traumatic brain injury (TBI) is a global health challenge owing to its high incidence rate, long-term sequelae, and complex pathophysiology with limited available treatment options. Food supplement rich in polyphenols has shown promising health benefits in TBI. Resveratrol, a phytoalexin stilbenoid commonly found in many plants, including grapes, nuts, and berries, is endowed with several health-promoting effects. In this review, the pathophysiology of TBI and the underlying mechanism for Resveratrol-induced neuroprotection in TBI has been discussed. The spectrum of injuries in TBI, including the acute primary injury, and delayed secondary injury often leading to other forms of neurodegenerative disorders, indicates the dysregulation of multiple pathways following TBI and its complex pathophysiology. Despite poor bioavailability and solubility, Resveratrol as a therapeutic in neurological illnesses, including TBI, is attributable to its ability to cross the blood-brain barrier, detectable level in the brain, and the lack of unfavorable toxicity. Substantial preclinical evidence has associated Resveratrol with protection against TBI and subsequent secondary brain injury as it has significant anti-oxidant, anti-inflammatory, and anti-apoptotic properties, emphasizing its promising scope in the treatment of TBI.
