Fearing Spring: The most common time for a relapse

I have to admit, I am growing a little anxious. Fearful even. Spring is here.

Spring is the most common time for an MS relapse, and so far I am 2 for 2: I went downhill in late September and October 2013 (culminating in my rather impressive first relapse), and in late October 2014 (resulting in my second relapse).

There is no definitive reason behind this, although (as so many things related to MS) it may be related to Vitamin D. Vitamin D levels are naturally lower after living through the winter – less sunny – months. The data back this up: winter is the least common time for an MS relapse, as Vitamin D levels are still adequate after being bolstered in the summer months. And then of course there is the relationship between MS and geography – the incidence of MS increases the further away people live from the Equator.

Research into how Vitamin D is related to MS – whether it is onset of the disease, the time between MS relapses, genetic absorption factors and ideal supplement levels – continues. I was in the Vitamin D PreVANZ trial throughout 2014, until my second relapse meant I was no longer eligible.

In the meantime as the MS community waits for results, I am taking an awful lot of Vitamin D and hoping for the best.
