Meta Analysis
Headache disorder and the risk of dementia: a systematic review and meta-analysis of cohort studies.
Until now, headache disorders have not been established as a risk factor for dementia. The aim of this study was to determine whether headache was associated with an increased risk of dementia. ⋯ Our results indicated that any headache was associated with an increased risk of all-cause dementia. However, additional studies are warranted to further confirm and understand the association.
