He will blame me when he is not able to find things that he has misplaced or lost.... and it seems to be harder for him to understand instructions, and he is slightly starting to call things by a different name than what they are. He works part time, when he gets home he complains about all the other workers and is very frustrated. I’m starting to worry....
Doctor's didn't know until 2014 that it was FTD Frontotemporal Dementia.

Sadly, 75% of people 75 years old or older have some form of dementia. If it is Alzheimer's disease, there are medications that will help boost the neurochemical processes if started early. They do not work forever and not on permanently damaged nerve pathways in the brain.
Whether he has dementia or not, now is a good time to establish permanent routines. The routines help to alleviate a lot of the stress in forgetfulness. Also try establishing permanent "homes" for items in the house to make it easier to find anything. You might want to streamline or downsize the amount of belongings or items that are on display to make it easier to "find" things too.
Good luck with your husband.
Both of those tests didn't reveal much, but sure enough she has dementia
and underlying mental issues.
My father is older, but it was when he started to get stumped looking for a word, or substituting an incorrect word (Can I get a glass of lightbulb?) that we realized something was going on.
We discovered he was having TIAs (mini strokes). As JoAnn29 suggested, a complete physical is appropriate - and soon. High blood pressure and high cholesterol can lead to strokes. These screenings and those for some aneurysms are all covered by Medicare.
As Tetertottering suggested, you need to spend your quality time now.
Maybe the job is aggravating another condition or just stressing him out. It could be time to quit.
As we age we do start to forget some things. I just tell myself that our brain at our age, all the filing cabinets in the brain are full, thus it just takes longer to find the information we want.... and if something is misfiled in our brain, it may take a couple days to retrieve it :) Usually I will remember at midnight !!
Every year our primary doctor gives us a battery of tests, and one test is a memory test. Is that something your doctor does? If not, ask for it.
