Changes in regional and global cortical thickness and age- and gender dependence of these measures on a large MS cohort that is a part of a multi-center clinical trial were investigated. Changes in regional cortical thicknesses were larger in the left hemisphere compared to the right. Males showed stronger age dependent cortical thickness than females. Strongest reductions in the thickness were observed in the entorhinal cortex and temporal poles in MS, the structures implicated in several neurodegenerative diseases. Weaker age dependent changes in both global and regional cortical thicknesses were observed in MS patients compared to controls.
