Abstract
Regional brain volumes have been compared at initial MRI scans and their change over time in 152 medicated and previously unmedicated male and female patients (age range, 5-18 years) with attention-deficit/hyperactivity disorder (ADHD) and 139 age- and sex-matched healthy controls.
Highlights
Vitamin A levels were measured in the cerebrospinal fluid of a total of 78 patients having idiopathic intracranial hypertension (IIH;n=20), elevated pressure of other causes (E-ICP;n=19), and normal pressure (N-ICP;n=39), in a study at the University of Utah, Salt Lake City, UT
Serum retinolbinding protein (RBP) and retinol are elevated in some patients with IIH (Jacobson DM, Berg R, Wall M, et al Neurology 1999;53:1114-1118)

Summary
Vitamin A levels were measured in the cerebrospinal fluid of a total of 78 patients having idiopathic intracranial hypertension (IIH;n=20), elevated pressure of other causes (E-ICP;n=19), and normal pressure (N-ICP;n=39), in a study at the University of Utah, Salt Lake City, UT. Higher CSF vitamin A levels found in some patients with IIH were significantly correlated (p=0.036) when compared with control E-ICP and IIH patients. Some patients with idiopathic intracranial hypertension have significantly higher levels of vitamin A in the CSF than patients with normal pressure or those with increased pressure due to other causes.
