Association of the body mass index with idiopathic intracranial hypertension

Abstract:

Objective: To evaluate the relation between idiopathic intracranial hypertension and the body mass index (BMI). Methods: We reviewed medical records of all adult patients whit idiopathic intracranial hypertension seen between 2006 and 2011 at "Hermanos Ameijeiras" Hospital. We used diagnostic modified Dandy criteria. The patients were divided in groups based on BMI and compared demographic data, symptoms, CSF opening pressure and number of lumbar punctures. Results: We included 36 patients (29, women, mean age 34.2 ± 8.1 years). Sixty-one percent of patients were obese, 25% had overweight and 14% had a normal BMI. CSF opening pressure was higher in obese patients (34.3 ± 3.8), compared with overweight patients (30.6 ± 7.6) and those with normal BMI (291 ± 9.0) (p < 0.0001). Conclusion: Young women were more affected. Obese patients showed a higher CSF opening pressure on lumbar puncture, compared with overweigh and lean individuals.
