@Mummyoflittledragon I just wanted to join you in saying that brain fog is an overlooked and under researched symptom of a few chronic illnesses (I have one too). Its one of the most distressing symptoms for me.
I’m writing this out in here though initially was going to put it in a private message. But actually, though it’s a diversion from the point thread (sorry Op!), maybe others will read and it might be useful in some way...
I totally get you MummyOfLittleDragon, I have a first in my chosen degree subject and spent over a decade near the top of my profession... yet I cannot remember nouns to write a shopping list.
Brain fog comes and goes, and so often put down to tiredness or some other subjective experience that we should just push through and stop complaining about.
I wish someone would do some proper research on it, as I suspect the results would be startling.
I have my own anecdotal evidence that indicates for me, that research on the symptoms and defining how characteristics of ‘brain fog’ would be really interesting:
I applied for a governmental job a few years ago, when first diagnosed with my illness.
The application process included an IQ test that I should have aced, but I really, really, struggled with.
So I used a practice site recommended many times over a 4 week period and it was then I got to see exactly what brain fog did to me:
When I was experiencing brain fog I consistently scored 30-35% on each practice test I did. No matter how much effort I put in. No matter how much coffee I drank / energy drinks / pep talks I gave myself or breathing exercises etc. I simply couldn’t push my way through it. Even when I felt that maybe this time I was beat the fog, I still failed the test.
When I stopped, rested and pounced on a moment when the fog had lifted, I consistently scored 88-93%.
I never scored in between. It was either one or the other, no matter how I tried to jog the results.
That’s what brain fog does.
That’s it’s power.
It’s not being a bit tired but being able to shake it off.
And although I still do catch myself trying to push on through it, if at all possible, I stop, rest and then accomplish the task in a fraction of the time later... it’s just horrifying that something can block you from being able to function like you, and that really, you have so little control over it.
