Metabolic dysfunction contributes to mood disorders after traumatic brain injury

Area of Science:

• Neuroscience
• Metabolic Disorders
• Psychiatry

Background:

• Traumatic brain injury (TBI) is a major cause of death and disability.
• TBI survivors often experience mood disorders like anxiety and depression.
• Metabolic disturbances in amino acids, lipids, iron, zinc, and copper are linked to these mood disorders.

Purpose of the Study:

• To review the impact of metabolic dysfunction on mood disorders after TBI.
• To explore therapeutic strategies for anxiety and depression post-TBI.
• To highlight the role of specific metabolic pathways and elements.

Main Methods:

• Literature review of PubMed and Web of Science databases.
• Focus on mechanisms linking metabolic dysfunction to mood disorders post-TBI.
• Emphasis on glutamate, kynurenine, lipid, iron, zinc, and copper metabolism.

Main Results:

• Metabolic dysfunction contributes to mood disorders via glutamatergic and kynurenine pathways.
• Endocannabinoids, iron deposition, ferroptosis, zinc deficiency, and copper dysregulation are implicated.
• Metabolic dysfunction's impact on mood disorders in the elderly TBI population is also discussed.

Conclusions:

• Metabolic dysfunction is a significant factor in post-TBI mood disorders.
• Targeting metabolic pathways offers a promising therapeutic strategy.
• Rectifying metabolic imbalances is a viable approach to managing anxiety and depression after TBI.
