BackgroundIdiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure without evidence of a tumor or any other underlying cause. Headache and visual disturbances are frequent complaints of IIH patients, but little is known about other symptoms. In this study, we evaluated the patients' perspective on the burden of IIH.MethodsFor this cross-sectional study, we developed an online survey for patients with IIH containing standardized evaluations of headache (HIT-6), sleep (PROMIS Sleep Disturbance Scale) and depression (MDI) in relation to BMI, lumbar puncture opening pressure (LP OP) and treatment.ResultsBetween December 2019 and February 2020, 306 patients completed the survey. 285 (93 %) were female, mean age was 36.6 years (± 10.8), mean BMI 34.2 (± 7.3) and mean LP OP at diagnosis was 37.8 cmH2O (± 9.5). 219 (72 %) of the participants were obese (BMI ≥ 30); 251 (82 %) reported severe impacting headaches, 140 (46 %) were suffering from sleep disturbances and 169 (56 %) from depression. Higher MDI scores correlated with higher BMI and increased sleep disturbances. Patients with a normalized LP opening pressure reported less headaches, less sleep disturbances and less depression than those with a constantly elevated opening pressure.ConclusionsIn addition to headaches and visual disturbances, sleep disturbances and depression are frequent symptoms in IIH and contribute to the patients' burden. Structured questionnaires can help to identify IIH patients' needs and can lead to personalized and better treatment.
