Review Meta Analysis
Comorbidities of primary headache disorders: a literature review with meta-analysis.
Primary headache disorders are common and burdensome conditions. They are associated to several comorbidities, such as cardiovascular or psychiatric ones, which, in turn, contribute to the global burden of headache. The aim of this study is to provide a comprehensive description of the pooled prevalence of comorbidities of primary headache disorders using a meta-analytical approach based on studies published between 2000 and 2020. ⋯ Some of the most relevant comorbidities of primary headache disorders - back pain, anxiety and depression, diabetes, ischemic heart disease and stroke - are among the most burdensome conditions, together with headache themselves, according to the GBD study. A joint treatment of headaches and of these comorbidities may positively impact on headache sufferers' health status and contribute to reduce the impact of a group of highly burdensome diseases.
