Is a subacute lacunar infarct serious, I have a brain tumour which Is now terminal, and 2 months again I had a right sided stroke which I managed to get back to normal after about a month,with feeling and movement normal but with slight imbalance problems occasionally. Had MRI which showed the lacuna infarct, is this due to the tumour and what are the chances of it happening again, what symptoms would I get? I'm 51. Thankyou. Is there any preventative measures to take.
