I don't know much about this particular type of issue, but FWIW one of my professors in graduate school (Genetics), a brilliant, charming, and charismatic man, could not even find his way from his office of 20 years to the lecture hall next door without following someone else. I think his wife had to drive him around, as this was about 20 years ago so of course pre-GPS. I didn't know him that well so don't know if he had the other problems you describe, but I think you're in good company. Best of luck finding help.
