A series of studies unequivocally show a true absence of autoimmune disease aggregation in MS patients and their families.

Cancer Risk Is Reduced in Multiple Sclerosis

November 19, 2012

The overall decreased cancer prevalence in patients with MS warrants further study and may represent an effect of increased immune surveillance in this autoimmune disease.

Venous Thromboembolism and Multiple Sclerosis

October 19, 2012

Venous thromboembolism is twice as likely to develop in patients with multiple sclerosis than in controls. Although the absolute risk of VTE is low in MS patients, thromboprophylaxis may need to be considered.

Smoking and Multiple Sclerosis

October 18, 2012

Meta-analyses of all available data have shown that smoking is associated with a 50% increased risk of MS.

Multiple Sclerosis and Epstein-Barr Virus: Is there a Connection?

September 24, 2012

Although genetics risk explains the familial clustering of MS, it cannot fully explain the geographic distribution of MS and the changes in risk that occur with migration. Infections have been suggested as a possible explanation. The most convincing candidate for involvement in MS is the Epstein-Barr virus.

The Importance of Bone Health in Multiple Sclerosis

September 12, 2012

Even at disease onset, patients with MS have significantly lower bone mineral density than healthy controls. Close attention needs to be paid to the bone health of these patients.
