Right side paralysis. This further?

My mother had an anxiety attack which caused right side paralysis. She was unable to lift her hand and breathe properly. We took her to emergency care where we were advised that this is a severe attack and thermolization injection is required but there was chance of bleeding/side effects due to that, her CT scan,ecg,bp was normal.she was able to speak and able to walk(with support) and lift her leg as well.we went against the advise and the only medication taken was ecosprin. After a while she was able to lift her hand as well and got her discharged. She's doing better as of now(able to lift hand, though not as easily as the other one).should she continue with this medication? What precautions/diet can be followed to prevent this further? Will physiotherapy help. The only reason we didn't go for medical advice is because there was no proof or guarantee of it working and prevent side effects.
