Mine are quite subtle, and a lot of the time I can’t tell if it’s the MS or fatigue. The latter still caused by MS, of course, but I mean I can’t tell, sometimes, if there’s actual “damage”, or if I’m just getting too exhausted to think straight.
Sometimes I start to spell things phonetically, even when it’s not difficult words, and I am - or should be - well aware of how to spell them.
The same with reading. Sometimes I get a mental block with a common word. For example, reading “curtain” as “curTAIN”, as if it were a verb (like “retain”), and then wondering what does it mean to “curTAIN” something, and why does the sentence not make sense? Then I go: “Oh yeah, of course! It must be CURTain. Duh!”
Exactly the same with my watch. Once or twice, I’ve looked at the face, and it was as if I had no idea how to read a watch, and had never learnt to tell the time at all. Only very briefly - probably for less than a second before it all fell into place. But just for that instant, the face of the watch was completely incomprehensible to me, as if I didn’t know what one was.
Another strange thing I do is forget where the light switches are - in a house I’ve lived for over 20 years! I have more than once caught myself feeling for a light switch in a place there has never, EVER been one. It’s not even that there used to be, and I’ve momentarily forgotten. Whether I’m remembering a different house altogether (the one where I grew up?) I can’t say.
