OBJECTIVE: To assess the relative contributions of white matter (WM) and gray matter (GM) volume loss to spinal cord atrophy in multiple sclerosis (MS). DESIGN: Postmortem study of transverse sections obtained from 5 levels of the spinal cord, with measurement of the cross-sectional GM and WM areas. SETTING: Department of Neuropathology, University of Nottingham, Nottingham, England. PATIENTS: Fifty-five MS cases and 33 controls. MAIN OUTCOME MEASURES: Size of the WM and GM areas. RESULTS: The WM area was significantly reduced in MS cases in the upper but not the lower cord levels. The GM area was not significantly different between MS and control cases. CONCLUSION: Spinal cord atrophy in MS is due to WM rather than GM volume loss.
