Periodic Paralysis, myotonia, channelopathy and ME

[Jonathan Edwards]

I just assumed it’s cataplexy. Want to move but can’t. Just wait until you can. Tends to be all of me though.

That would be intriguing since we have been discussing the relation of ME/CFS to narcolepsy.
The odd thing is that cataplexy is usually brought on by pleasant surprise (not by nasty surprise). It seems to be triggered by some very specific events associated with emotion signalling, maybe insula or amygdala or something. But perhaps there is a variant that isn't that has some link to ME/CFS.

That makes it sound as if a CNS event triggered by chronic pharmacological issues led on to an ME/CFS course rather than being a feature of the ME/CFS that followed?

If ME/CFS involves synaptic control somewhere around the hypothalamus, as various things might suggest, then it wouldn't be too surprising that if could be set in motion by other CNS problems as much as cytokines or lymphocytes from infection I guess.

Well, that's another point in favour of my theory that my alcoholism was a factor in my developing MECFS.

Although I had a clear infectious trigger at least for my definite onset, and my prodromal onset (or whatever) happened during a winter when I was going to a lot of pubs and parties, and I'm sure I remember having a bug or two.

Hopefully if the CNS event trigger is the really a factor we will still be able to break the signalling cycle via the immune part of the loop.

Mine's a bit cataplexy-like, but the trigger's different: mostly rest or cold, but high carb loads can also do it.

It only affects my limbs and a small patch under my chin, everything else is fine. I used to be unable to move for about 30 to 40 minutes. The last episode was the morning Tony Blair was elected in 1997; since then it's only been partial, so I can move my limbs but not control them very well. If I try to walk I stagger as if I'm drunk.

It's never been a frequent occurrence, and I only get it now when I'm particularly well. At those times I'm more likely to go out in the cold for long enough to affect my muscles, or collapse for a rest after doing sustained activity.

The first episode coincided with getting ill, but also with menarche (unusually late at 17).

I have never been able to move a small patch under my chin.
I guess this is something else.

Same - especially with no obvious preceding infection. In my own case - and, to be clear, only in my own case -, I've always been pretty certain that this is all fundamentally my fault.

I've always been pretty certain that this is all fundamentally my fault.

I sometimes feel this way too. But I don't think it's a good way to look at things really.
