Objectives Both Chiari malformation type 1 ( CMI , i.e., the idiopathic caudal ectopy of cerebellar tonsils into foramen magnum) and idiopathic intracranial hypertension ( IIH ) are characterized by reduced intracranial compliance ( ICC ) due to disturbed circulation of cerebrospinal fluid ( CSF ). An increasing body of evidence links cardiovascular disease to CSF circulation disturbances. The aim of this study was to explore whether the prevalence of cardiovascular risk factors in patients with CMI or IIH is higher than in the general population. Materials and Methods Among the patients with CMI or IIH treated at our department during the period 2003–2014, we identified those with history of arterial hypertension ( AH ), myocardial infarction ( MI ), angina pectoris ( AP ), or diabetes mellitus ( DM ). For comparison with a control population, we retrieved information about the prevalence of AH , MI , AP , and DM among participants of the North‐Trøndelag Health Study 3 ( HUNT 3). Results Data from 48 CMI and 52 IIH cases were available. Compared to data from the 42,461 individuals participating in the HUNT 3, we found increased prevalence of DM in male CMI as well as female IIH cases, and of AH in female IIH cases. Body mass index ( BMI ) was significantly increased in both female and male IIH cases. Prevalence of MI and AP in the CMI and IIH cohorts was extremely low and therefore not further studied. Conclusions This study provided evidence of an increased prevalence of DM in male CMI as well as female IIH cases and of AH in female IIH cases. Although requiring further exploration, these findings point to AH and DM as potential risk factors in the pathophysiology of CMI and IIH .
