My 67 year old husband was determined by his neuro last spring as being "borderline" for cognitive impairment of an unknown specific kind. His follow up is in a few weeks. Earlier this week I sent her a letter detailing his history, personality, recent losses and suspicious behaviors as I cannot say these things in front of my husband. In the letter, I asked her to please consider or rule out ADD, Depression and HF Autism when she meets with us next month. He already thinks I am "trying to have him committed" even though it was his PCP who first voiced concern and referred him to a neuro. Today, more than a few things sparked grave concern on my part concerning my husband's cognitive health, including when we stopped for lunch at a restaurant while doing errands and he forgot to turn the car off. We were heading into the restaurant when I heard a noise from the car...and it was the engine running!! Even before...and after...this incident, he seemed to have several "episodes" of cognitive problems that concerned me. It was like this happened overnight. He would have issues and episodes that concerned me in the past but usually not so many in one day. Can a change for the worse happen seemingly overnight?? I have decided that, if he has one more day like this, I will try to get him into the neuro asap, as she told me to do at the first appointment. Of course, he is in total denial. After the car incident he said, "I bet you think I am totally off my rocker now."
