My husband’s PCP recommended the testing, therefore my husband was very willing. At the neuropsychologist’s office, I came in the room, but sat back out of sight and didn’t make a peep. The neuropsychologist was very warm and kind, presented the test items as something fun, spoke the instructions clearly, and moved on when test items “stumped” him. It was a very good experience.

You asked about adjustments made to daily life- I taped little signs around- on the fridge-“Be sure to close the door”, on the faucets- “Be sure to turn off “, on the back door- “Don’t leave- plumber coming”. I found paid help for the lawn care, snow removal, and small household repairs. He was happy to give that up! I bought a clock on Amazon with the day of the week, date, time, general time of day (morning, afternoon, evening).
I had been doing the finances, I set up the online app for his credit card to notify me of any usage over $1.00. He got into online shopping, often ordering duplicates or nutritional supplements to be delivered monthly. I hid the checkbook after I walked in on him getting ready to write a $250 check to a scammer he had allowed to take over his computer. The guy (with a heavy accent) claimed to be calling from Microsoft and needed that check to clear the PC of “viruses”. I told him his mother would be ashamed of him trying to steal from a senior.
It was kind of like a constant monitoring as best I could. He was happy to have me take over driving, but very unwilling to have me do his medications.
