MS risk factors: the top 6

Before day 2 commences, a quick word on a wonderful symposium on Multiple Sclerosis (MS).

MS epidemiologists and researchers dissected the topic Causes/Triggers of MS. Speakers were David Hafler, Alberto Aschiero, Lisa Barcellos and Larry Steinman. And the top 6 are

  • Genetics
  • Tobacco smoking

 

smoking

  • Vitamin D deficiency

  • EBV infection
  • Overweight in early age
  • High salt intake

I suggested to David we should only be looking for correlation rather than causation (an idea I picked up from a great book Big Data).


He strongly disagreed! He believes genome wide association studies (GAS) have confirmed the cause for MS. I think the search for a definite cause is probably futile but we define cause flexibly. Alberto made the point that even if all the known risk factors were eliminated, MS will still be very prevalent
