Should I call a welfare check on a schizophrenic family member?

My 64 year old mom has severe mental health issues and has been institutionalized multiple times (Baker Acted). She has every symptom of Schizophrenia, but doesn’t have any official diagnosis.

We usually call once every week or so, but the last 2 months she’s gotten increasingly convinced that I’m not really her son. I’ve called her a few times the last 2 weeks now and haven’t had any response (call or text). About a week ago she had a request come through my email to reset her gmail password, so as of a week ago she was alright. I’m tempted to call in a welfare check, but the last time I did she got aggressive towards the police and almost got in trouble. Do I risk it again, or just assume she’s cut contact from me? I also didn’t realize her location was shared with me on her phone, so maybe I wait a day or 2 to see if it moves around?
