I just read that during times of inflammation, the blood brain barrier becomes more permeable, which makes avoiding inflammation all the more important in helping to keep MS symptoms at bay.
I enjoyed this article about things that cause inflammation:
http://www.womentowomen.com/inflammation/causes.aspx, a recommended read if you are serious about lessening your inflammation. Also more specific diet suggestions for reduce inflammation: http://www.womentowomen.com/inflammation/naturalantiinflammatories.aspx
Just a quick overview:
Diet is huge, too much insulin causes inflammation, so low carb diets are helpful.
A proper balance of omega-3 and omega-6 oils is crucial.
Avoiding food sensitivities helps.
Intestinal inflammation (which more of us have than we realize have) can be helped by probiotics.
Stress increases cortisol levels which affects insulin and increases inflammation.
Hormonal imbalances can also affect it. This article only mentioned menopause, but I am still interested in learn how hormonal changes in pregnancy and menstruation could affect inflammation.
Environmental toxins can contribute.
Panic attacks or being severely frightened (dream or other wise) causes the blood vessels to dilate. Could a vein malformation and fright cause more blood to be refluxed? Probably.
