revealed that AG counts were higher in IIH patients than in healthy individuals; however, this difference did not reach statistical significance (2.41 ± 1.12 vs. 1.50 ± 0.54, p = 0.096). 81 Recent studies have suggested that AGs may not be as efficient as mature structures, which may represent fibrotic degeneration of the arachnoid villi. 84 Furthermore, many individuals with normal CSF systems lack AGs, suggesting that their actual
