Should we visit every time my LO in MC calls and is scared?

Before rushing over there: Your mom should, first, call the memory center and inquire about how her sister is doing that day.

She should also tell her sister: I am coming over on x day, or tomorrow, etc. She ids catering to her and in turn, she’s twisting your mom into knots. This dementia disease is a marathon not a sprint. Your mom cannot continue multiple trips to the MC every day indefinitely. Plus her sister needs to develop routine on her daily schedule - which will reduce her anxiety

She should only answer her sister’s calls once or twice a day. Or call her sister first at a time convenient for her. She doesn’t not have to answer every phone call. That just encourages her sister to call more often. The MC WILL call your mom if your mom is actually needed.

If your aunt still has her own cell phone, it needs to disappear for a few days. Maybe it needs ‘repaired’ or some messages reviewed, etc. if you’d mom keeps it for a few days, her sister may forget she even has a phone. Again - the MC will call your mom if she is needed.

Finally -anxiety medication is needed here. Talk therapy won’t help because her sister won’t remember coping techniques between sessions.
