Can stuttering lead to brain fogginess?

Can stuttering lead to brain fogginess? I’ve had a stutter since second grade I’m 27 now and a lot of times when I’m in conversations, I will have brain blocks on common words that are small, mostly elementary level and I can say the word in the same sentence but later down the line will not remember what the word is. I’m curious on if this is because of my stutter or if this is maybe something else.
