Abstract: Traumatic brain injury (TBI) is a major global health issue that affects millions of people
every year. It is caused by any form of external force, resulting in temporary or permanent impairments
in the brain. The pathophysiological process following TBI usually involves excitotoxicity,
mitochondrial dysfunction, oxidative stress, inflammation, ischemia, and apoptotic cell death. It is
challenging to find treatment for TBI due to its heterogeneous nature, and no therapeutic interventions
have been approved thus far. Neurotrophins may represent an alternative approach for TBI
treatment because they influence various functional activities in the brain. The present review highlights
recent studies on neurotrophins shown to possess neuroprotective roles in TBI. Neurotrophins,
specifically brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) have demonstrated
reduced neuronal death, alleviated neuroinflammatory responses and improved neurological
functions following TBI via their immunomodulatory, anti-inflammatory and antioxidant properties.
Further studies are required to ensure the efficacy and safety of neurotrophins to be used as TBI
treatment in clinical settings.
