Hi @mrgnflynn and welcome to the community. Sorry to hear of your mom’s stroke.
Stroke can affect someones behaviour & personality and I have copied in a Stroke Association leaflet for you to have a read off which may help a little bit.
It’s difficult if your mom won’t engage with rehab etc butit may be that 1 month in is just too soon for her to do so. She is probably scared & not sure what is going on. The first 6 months the brain tries to rewire itself & needs plenty of rest. But on the positive side people often improve over time and things start to settle. She may never get back to how she was previously but if she tries to engage in recovery she should make some improvements. It is a long journey though & given the severity of her stroke you need to be prepared for that.
Is it possible to find some innovative ways to so “rehab” with her. Make it more like an everyday thing rather than something specific she has to do.
Has anyone told her about her behaviour? Told her it is unacceptable? Sometimes you need to be very blunt with them.
I don’t know if these links will help but aggressive behaviour has been discussed before on the forum.
