Idiopathic Intracranial Hypertension (Pseudotumor Cerebri): Descriptive Epidemiology, Clinical Features, and Visual Outcome in Parma, Italy, 1990 to 1999

Abstract

The incidence rate found in this study is lower than the incidence reported in previous US and Libyan studies. A significant difference in overweight distribution is observed comparing percentage of body weight between US and Parma populations. As overweight and obesity are important factors contributing to IIH development, it is possible that their low percentage in the Parma population may, at least partially, explain the low IIH incidence observed.
