addlebrain
Muddled thinking person
An addlebrain is a person whose thinking is muddled or confused—someone who can't seem to get their thoughts straight.
The word treats the brain as something that has gone bad, like an addled egg.
It's mildly insulting but often affectionate: Don't mind him, the old addlebrain forgot his glasses again.
