Calcium supplementation may increase the risk of dementia in elderly women with cerebrovascular disease

In October 2016 researchers from Sweden and the UK published the results of their study to assess whether calcium supplementation was associated with the risk of dementia. 700 women with no history of dementia aged 70-92 years were included in the study and followed up for a period of 5 years. They underwent assessment at the start and end of the study and information on the use and dosage of calcium supplements collected. Results showed that calcium supplementation appeared to be associated with the development of dementia in individuals with either a history of stroke or presence of white matter lesions, but not in those without these conditions.
