Concerns that the prevalence of other chronic conditions (including cardiovascular conditions) may be common in people newly diagnosed with multiple sclerosis (MS) were further confirmed in a subsequent study of 140,020 people (23,382 with MS) and a matched control group of 116,638. This study was published on  in the online issue of Neurology, the medical journal of the American Academy of Neurology. While the scope of this study does not appear to include chronic cerebro spinal vascular insufficiency (CCSVI) it does ring important warning bells. Separate research identifies up to 80% of the MS population as having CCSVI related comorbidities - adding even greater weight to concerns about underlying cardiovascular disease.
