Comparative Study on Serum Levels of 10 Trace Elements in Schizophrenia

Area of Science:

• Neuroscience
• Biochemistry
• Psychiatry

Background:

• The causes and biological mechanisms of schizophrenia are not fully understood.
• Trace elements play crucial roles in various biological functions, potentially influencing neurological health.

Purpose of the Study:

• To investigate the relationship between serum concentrations of 10 trace elements and the risk of developing schizophrenia.
• To identify specific trace element levels associated with schizophrenia in a matched case-control setting.

Main Methods:

• A 1:1 matched case-control study involving 114 schizophrenia patients and 114 healthy controls, matched for age and sex.
• Serum samples analyzed for nickel, molybdenum, arsenic, aluminum, chromium, manganese, selenium, copper, iron, and zinc using inductively coupled plasma-mass spectrometry.
• Conditional logistic regression models applied to assess associations between trace element levels and schizophrenia risk.

Main Results:

• Lower serum selenium (≤72 ng/mL) and copper (≤0.97 μg/mL) levels were associated with an increased risk of schizophrenia.
• Higher serum manganese (>3.95 ng/mL) levels were also linked to an elevated risk of schizophrenia.
• Schizophrenia patients exhibited significantly lower selenium and copper, and higher manganese levels compared to healthy controls.

Conclusions:

• Serum selenium, copper, and manganese levels are potential biomarkers for schizophrenia risk.
• Imbalances in these trace elements may contribute to the pathophysiology of schizophrenia.
• Further research into trace element supplementation or regulation could offer novel therapeutic strategies for schizophrenia.
