What would indicate I have a form of dementia?

I’m no expert but my vote is stress. It’s real and it’s no joke.

As for “is it Alzheimer’s?”, I heard a professor explain it like this:

If you can’t remember where you put your keys, that’s forgetting.

If you can’t remember what keys are for, that’s Alzheimer’s.

Its probably stress and some anxiety. Are you Executor? Is probate completed? If not, not sure how they can sue? Were they left out of the Will? Or didn't get what they think they were due. Funny, maybe ur brother is entitled to something but we are not obligated to leave grandchildren anything.

I so hate that Wills are allowed to be contested. Wills are made for a reason. So the deceased wishes are carried out. If a child is left out, they are left out. But I do think a reason should be stated. "I leave my house to my daughter who has cared for me for 6 years. This is not to be contested".

If you are on Medicare you can set up your free annual wellness exam and have the anxiety discussion with your doctor. They might ask if you want to take the memory test but I wouldn't until after you've dealt with your stress, so that the test results aren't skewed from it.

Likely this is anxiety.
Time to see your doctor, right?

If you are executor of your mom's will I can't see how YOU can be sued.
Rathe, this would be a contest of a will, which is their right. DO LET THEM KNOW that your MOM's assets are what pay your attorney costs, so any money may go to attorney's, but that is what it is.
It is very unlikely that ANY contest of a will can win.

However, you are unlikely to be able to sell mom's house, so get a rental agency to handle its rental and go back home. You may need medical supervision, but it is EXCEPTIONALLY unlikely, as much as anxiety disorder can mimic dementia (lost stuff and forgetfulness especially) that this is dementia.

Have you hired your own lawyer to help you through this lawsuit? You need help with the stress of being sued long before having dementia is considered. I wish you peace in the storm

Pattycake, you have been under so much stress,
6 years is a long darn time, it could even be a form of PTSD from years of caregiving and not taking care of yourself.
And now on top of it you are dealing with family bs.
Of course your stressed.
And you lost your mom
Id be more concerned if you were thinking normal.
Get some counseling and breathe.
