The reason I think it may be useful to look at migraine when thinking about ME/CFS is that the two conditions have features in common.
- genetic correlation of rg=0.45
- similar buspirone prolactin result
- more women than men affected
- possibly a bimodal age of onset in migraine although slightly later than ME/CFS. Migraine late teens/20s and around 50. ME/CFS 16 and around 37
- trigger occurs around 12 - 24 hrs before migraine 'event' whether that is migraine headache or vertigo episode or vomiting etc. The timescale obviously fits with PEM in ME/CFS
- the triggers can accumulate until a threshold is reached and a migraine is triggered. (At least in my experience the same is true for ME/CFS. For example I can do 15 minutes of activity and be fine one day. Another day I can have slept badly and when I do 15 minutes of activity it triggers PEM)
- there are often symptoms before and after the main 'event'. (Again only my experience but I get symptoms before the main PEM 'event' happens and whilst I'm recovering from it)
- there is quite a bit of symptom overlap with sensitivity to light/sound/smell, fatigue, brain fog etc
- both have symptoms body wide but usually no abnormalities are found when looking at a specific area.
- both can be extremely debilitating leaving people lying in a darkened room unable to look at screens, tolerate audiobook/radio etc. Yet neither are usually fatal.
- usually both groups say they need to lie down
- both are fluctuating and both can have temporary remissions or permanent recovery
I seem to always be taking about migraine on here. I promise there are lots of other threads I want to respond to but writing invariably makes me crash and I find that usually someone else makes the point I want to make.
I'm not saying that migraine is the same as ME/CFS and it may well prove to be a dead end. I just feel that as there are established migraine research teams looking in similar areas it would be worth at least getting their thoughts and maybe seeing if ME/CFS could be included in some of the research.
As I have eluded to before, but I think it is worth reiterating.....
I'm currently feeling like a 10 year old in a hotel, looking for the restaurant but have accidentally wandered into a conference of very clever people who are saying things that mostly go over my head, and I'm wondering what on earth I am doing here.
