@dh524 - Absolutely! It is so bad that I have abandoned reading instructions that are more than 3 steps and/or point and click. I was having an unusually bad day on the Corona Coaster - unable to name objects , etc. during my "LC" plumonary rehab appt. last week. I tried to explain the brain fog to the pulmonology physical therapist but she still looked puzzled after my attempt. You hit the nail on the head with your explanation! I am going to use that one.
