What happens in multiple sclerosis?
MS is an illness in which there are periodic flare-ups of inflammation as well as degeneration of nerve fibres that contribute to disability. Inflammation is experienced as relapses and can be seen on an MRI. Neurodegeneration is a more subtle process that damages tissue in the brain and spinal cord.
These two processes of inflammation and neurodegeneration during the life-long course of MS are explained in a slide/audio presentation by Dr. Mark Freedman from the MS clinic in Ottawa, Canada.
