Plasma magnesium in chronic schizophrenia. A preliminary report
International Pharmacopsychiatry
|January 1, 1979
Summary
Schizophrenic patients exhibit significantly lower magnesium levels compared to mentally retarded individuals. This finding suggests a potential link between magnesium deficiency and schizophrenia, independent of other factors.
Area of Science:
- Neuroscience
- Biochemistry
- Psychiatry
Background:
- Schizophrenia is a complex mental disorder with various proposed etiological factors.
- Mineral imbalances, particularly magnesium, have been investigated for their role in neurological conditions.
Purpose of the Study:
- To investigate serum levels of magnesium, calcium, and phosphorus in chronic schizophrenic patients compared to nonpsychotic mentally retarded patients.
- To explore potential correlations between these minerals and schizophrenia.
Main Methods:
- A cohort of 36 patients (20 chronic schizophrenic, 16 mentally retarded) was randomly selected from a hospital's chronic care wards.
- Serum levels of magnesium, calcium, and phosphorus were measured and compared between the two groups.
Main Results:
- No significant differences were observed in calcium and phosphorus levels between the schizophrenic and mentally retarded groups.
- Significantly lower magnesium levels were found in the schizophrenic group (p < 0.01) compared to the mentally retarded group.
- This difference was more pronounced when comparing chronic female schizophrenic patients to their female mentally retarded counterparts (p < 0.001).
Conclusions:
- Chronic schizophrenia is associated with significantly lower serum magnesium levels.
- Magnesium deficiency may play a role in the pathophysiology of schizophrenia.
- These findings were independent of hospitalization, diet, and medication.
