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 (chi 2 = 1.253, df = 2, P = 0.53) or Singh index (chi 2 = 1.039, df = 5, P = 0.96) was found between patients resident in high versus low water aluminum areas. No correlation was detectable between mental test score and Singh index (chi 2 = 0.95, df = 1, P = 0.33).
