This narrative review explores mitochondrial dysfunction and ferroptosis affecting neurocognitive outcomes in TBI and alcohol exposure, suggesting critical therapeutic targets.

Key Points

This review aims to synthesize research on the interplay between traumatic brain injury and alcohol, focusing on mitochondrial dysfunction and ferroptosis effects on cognitive outcomes.
Literature synthesis of current research on TBI and alcohol effects.
Examination of mitochondrial function, energy metabolism, and redox homeostasis post-injury.
Discussion of biomarker studies and preclinical models relating to neurocognitive outcomes.
Up to 50% of TBI cases involve alcohol intoxication, impacting recovery.
Mitochondrial dysfunction leads to impaired ATP production and excessive ROS generation.
Alcohol alters glucose metabolism and promotes ferroptosis, increasing neural tissue vulnerability.
