The recent discovery that bone homeostasis is directly regulated by the brain led us to hypothesize that it may be impaired by MS pathology. As cognitive impairment (CI) is a well-documented correlate of MS-related brain pathology, we tested the hypothesis that it is associated with reduced BMD.<\/jats:p>\n                  <jats:p>Objective: We aimed to determine if CI is associated with reduced BMD in patients with MS.<\/jats:p>\n                  <jats:p>Methods: We retrospectively studied the medical records of 56 patients with MS, \u226450 years old, with Expanded Disability Status Scale score \u22644.5 and with dual X-ray absorptiometry (DEXA) BMD measurement within 1 year of neuropsychological testing with a standard battery (MACFIMS).<\/jats:p>\n                  <jats:p>\n                    Results: In total, 23 (41.1%) MS patients had osteopenia or osteoporosis.
