Calcium & Cognitive Decline (2007)

A total of 4,500 elderly people were involved in a 5-11 year study of the effects of blood calcium levels on cognitive decline. Cognitive function was measured using the Mini-Mental State Examination (MMSE) and other measures of attention and memory. Higher levels of blood calcium (but still within the normal levels) was associated with worse cognitive function at the beginning of the study. They were also associated with a faster rate of decline in cognitive function during follow-up.
