Brain Iron Homeostasis and Mental Disorders

Area of Science:

• Neuroscience
• Biochemistry
• Nutritional Science

Background:

• Iron is essential for physiological processes, and its disruption causes severe health issues.
• The relationship between mental health disorders and iron homeostasis is understudied, leaving gaps in understanding psychological diseases.
• Impaired iron homeostasis is implicated in neurodevelopment, neurodegeneration, stroke, and cancer.

Purpose of the Study:

• To review pathologies and mechanisms linking iron homeostasis to mental disorders.
• To hypothesize how brain iron homeostasis impacts neuronal functions.
• To highlight the importance of trace element nutrition, specifically iron, in mental disorder pathology.

Main Methods:

• Literature review of studies on iron homeostasis and mental disorders.
• Analysis of potential mechanisms involving iron in neurotransmission, redox balance, and myelination.
• Synthesis of current knowledge to propose a hypothesis on brain iron homeostasis.

Main Results:

• Disruptions in iron homeostasis are associated with various neurological and systemic diseases.
• The precise mechanisms linking iron metabolism to mental disorders require further investigation.
• Maintaining brain iron homeostasis is hypothesized to support neuronal functions critical for mental health.

Conclusions:

• Investigating the link between trace element nutrition (iron) and mental disorders is crucial.
• A nutritional perspective on iron metabolism may provide novel insights for treating mental disorders.
• Further research is needed to elucidate the role of iron in the pathogenesis of psychological conditions.
