Silent stroke

my mum has been feeling lightheaded and odd. Doctors sent her for a CT scan. Just had results today- there is small scarring which indicates she has had a silent stroke previously. She's on beta blockers and has been prescribed aspirin. I can't help but worry? 

Hi Kate, you are bound to worry, but,more importantly, you know what has happened. Medication should keep your mum stable. She might need to rest more and you need to make sure she doesn't overdo things.
