On Monday Italian researchers said a faulty immune reaction may be responsible for the development of epilepsy. The researchers used mice and found that seizures are linked to brain changes, which made immune cells stick inside its blood vessels.

Genzyme and Bayer have reported Phase II study results demonstrating the potential of alemtuzumab in treatment-naive MS patients. Although the product's efficacy is now established, two recently initiated Phase III trials will reveal whether alemtuzumab should be used as an early treatment or if safety issues will restrict it to patients who continue to relapse on currently approved MS therapies. Results from the final three-year analysis of the 334-patient CAMMS223 study showed that...
