The relationship between bone mass and dementia in elderly hip fracture patients from areas with different aluminium concentrations in water supplies has been investigated, to determine whether a high concentration of aluminium in the drinking water and the negative calcium balance of age-related osteoporosis together predispose to senile dementia.
Mental test scores were recorded on admission to hospital, and Singh indices of radiographs taken at that time assessed blind by a single trained observer.
No significant difference in either mental test score (X=1.253, df=2, P=0.53) or Singh index (X=1.039, df=5, P=0.96) was found between patients resident in high versus low water aluminium areas. No correlation was detectable between mental test score and Singh index (X=0.95, df=1, P=0.33).
