How do I know if my Mom is mentally stable?

You need to get her to her doctor asap, could be a urinary tract infection !

Im sorry. I'm in the same boat. I'm fairly sure dementia is setting in but he's getting mean about seeing a doctor about it. Says anything and everything to hurt me and throw me off track. I feel like I'm the one loosing it some days. Hang in there. No one can push our buttons like our parents can.
