I read somewhere that even if you get steroids during an attack it doesn't do anything but make the symptoms clear up faster and doesn't prevent further damage. Is that true?
If I remember correctly, corticosteroids such as prednisone induce white blood cells to undergo apoptosis, i.e., programmed cell death. Thus, by causing a majority of a patient's white cells to die off, the inflammatory damage induced by those white cells should cease thereby shortening an attack. What I don't specifically know is if there might be a neurodegenerative process that is triggered by the inflammatory cascade which continues even though the inflammation has ceased.
