    Summary

    Zinc is crucial for brain function, impacting essential and toxic element levels. Zinc deficiency can lead to behavioral changes, altered brain morphology, and potentially permanent damage, affecting neurochemistry and neurotransmission.

    Area of Science:

    • Neuroscience
    • Biochemistry
    • Nutritional Science

    Background:

    • Zinc plays a vital role in numerous biological processes, including brain function.
    • Understanding zinc's impact on essential and toxic element metabolism is critical for neurological health.
    • Existing research highlights potential links between zinc status and various neurological and psychiatric conditions.

    Purpose of the Study:

    • To review the multifaceted effects of zinc nutriture and metabolism on brain function.
    • To explore the relationship between zinc and the metabolism of essential and toxic elements in the brain.
    • To discuss the implications of zinc status for neurological diseases and neurochemistry.

    Main Methods:

    • Literature review of studies on zinc nutriture, metabolism, and brain function.
    • Analysis of research on elemental concentrations (zinc, copper, manganese, etc.) and toxic elements (aluminum, lead) in relation to brain health.
    • Examination of studies investigating behavioral changes, brain morphology, and neurochemical alterations associated with zinc status.

    Main Results:

    • Zinc nutriture significantly influences the concentration and metabolism of both essential and toxic elements in the brain.
    • Zinc deficiency is associated with behavioral changes, altered brain morphology, and potential long-term neurological damage, especially if occurring perinatally.
    • Zinc status affects various neurochemical pathways, including nucleic acid and protein synthesis, neurotransmitter systems, and nerve growth factors.

    Conclusions:

    • Zinc is indispensable for maintaining optimal brain function and neurological health.
    • Disruptions in zinc metabolism can precipitate or exacerbate neurological disorders and impact neurodevelopment.
    • Further research into zinc's role in neurotransmission and its therapeutic potential is warranted.
