New flashing-light test may be able to determine multiple sclerosis drug success

Written by Kimberley Ndungu (Future Science Group)

In a study published in the Proceedings of the National Academy of Science, a team of researchers from the University of Wisconsin–Madison (WI, USA) discovered that changes in the speed of electrical signals across the optic nerves may reflect recovery from myelin loss in multiple sclerosis (MS). For many MS patients, symptoms – such as numbness, weakness and vision problems – come and go, due to them developing a relapsing–remitting disease. Further, with time, patients develop progressive MS, which damages axons by eating away at the myelin. “There are many treatments for people with relapsing–remitting disease which are quite successful...
