Can someone help me find resources for the state of Ohio for my mom who is on Medicare?

There was a lot of mental abuse in my childhood, so I can only be around her for a very short period of time before the anxiety takes over. She was diagnosed with dementia about 5 years ago, had been doing pretty well up until recently. I at first thought maybe it was just her age (76), but it's happening often, and there are other things as well. The fire department has been to her apartment I think 4 or 5 times to turn her smoke alarms off (the apartment building she lives in requires the F.D. come to turn the smoke alarms off when they have been on), The last time was because she forgot she had put ice cube trays on a skillet and set the skillet in the oven. That evening she was gonna cook a pizza, and and melted the ice cube trays all over one side of the oven and filled her apartment with smoke. Now, I just moved up here to Ohio from Alabama - She knows my husband and I are in need of a vehicle , and she has one, (we are waiting on a settlement from an accident we were in) and she being manipulative about using the car. She has been SO manipulative my ENTIRE freaking life. She used to threaten she would commit suicide to me if she didn't get her way... I mean who the crap does this??? I suffer from Rheumatoid Arthritis and fibromyalgia. That's a lot in itself. Any stress causes me such sickness. But it's no point in trying to talk to her.Im so confused as to what to do- but I want to get her more help than what she gets now (housekeeper 2times every 2 weeks)
