    This study analyzed 16 elements in hair, blood, serum, and urine of patients with mania and depression. Molybdenum showed potential differences across tissues, but results require cautious interpretation.

    Area of Science:

    • Biochemistry
    • Clinical Chemistry
    • Trace Element Analysis

    Background:

    • Mental health disorders like mania and depression are complex conditions.
    • Understanding the role of elemental concentrations in these disorders is crucial for potential diagnostic or therapeutic insights.

    Purpose of the Study:

    • To investigate the concentrations of 16 elements in biological samples from individuals with mania, depression, and recovered states.
    • To identify any significant elemental differences associated with these mental health conditions across different tissues.

    Main Methods:

    • Neutron activation analysis (NAA) was employed to quantify 16 elements (Al, Ba, Br, Ca, Cl, Cu, I, Pb, Mg, Mn, Mo, Rb, Se, Na, S, Ti).
    • Samples analyzed included hair, whole blood, serum, and urine from normal controls, patients with mania/depression, and recovered patients.

    Main Results:

    • Significant differences in elemental concentrations were observed between the studied groups.
    • Molybdenum (Mo) was the only element showing significant concentration changes in more than one tissue type.
    • Other elements did not exhibit consistent significant changes across multiple tissues.

    Conclusions:

    • Elemental concentration differences exist in patients with mania and depression.
    • Molybdenum concentrations warrant further investigation due to observed variations.
    • Results should be interpreted with caution, and further research is needed to confirm findings and understand their clinical significance.
