Objective: To assess cortical gray matter (GM) changes in MS and establish their relevance to clinical disability and to inflammatory changes of white matter (WM) in patients with the relapsing-remitting (RR) and primary progressive (PP) forms of the disease. Methods: Conventional MRI examinations were obtained in patients with definite MS who had either the RR or the PP form of the disease. An automated analysis tool was used with conventional T1-weighted MR images to obtain total and cortical brain volumes normalized for head size. Total brain lesion load was estimated on conventional proton density and T2-weighted MR images. The relationship between volumetric MR measures and scores of clinical disability was assessed. Results: Normalized cortical volumes (NCV) were lower for both RR and PP MS patients than for normal control subjects (p <0.001) but were similar between the two patient groups (p > 0.5). NCV decreases in both patients groups were detected even in those patients with short disease duration (
