Brain fog/ cognitive dysfunction

Merged thread
How would you describe your brain fog to others?

For me, it feels like both information overload and my mind being empty at the same time. It sounds weird, because they're two opposites, but that's how it feels to me. Like my mind is both over-full but empty.

 

Difficulty thinking. Thinking requires more effort, is slower, is interrupted frequently by losing attention. Sometimes formulating clear thoughts is not possible (this particular problem is I suspect what is really meant with "brain fog"). The effort of thinking becomes painful over time.

 

Tumbleweed - without the tumbleweed.

(of course there are 'degrees' within that - there are more than several types of brainfog - but they all, broadly speaking, have roughly the same effect on thought as being smacked in the head by a train. I speak from experience, having been smacked in the head, by a train, whilst crossing some tracks, after which I was more mentally functional than I am with brain fog - but the stunning is very similar)
