Is there support groups for spouses of dementia patients [View all]

We don't have a definitive diagnosis yet, but the neurologist who saw my husband today said "there is something going on".
I have been dealing with this issue for a few years. He gets scammed by phone and email scams, 30 grand lost over the last 5 years.
I have taken over our finances as much as I can. When I have to leave the house, I put his phone on do not disturb and make him promise to stay off the computer

I'm a strong woman but sometimes a little support would help.
