Hello Claudia,
Welcome to the NeuroTalk Support Groups.
I'm sorry you have to wait so long to see your Neurologist. Perhaps you could go back to see your GP in the meantime to ask specific questions you may have. Otherwise you're going to worry so much and that is understandable.
I pulled up an article regarding incidental ischaemic changes on MRI and was surprised that it seems to be quite a common finding. There is also a graph showing age related incidental findings.

You could try a forum search for keywords. I used term - ischaemic - but there seem to be more posts using the other spelling of ischemia without the a.

It seems way too long for you to not have a doctor explain the findings to you. If I was in your situation, I would ask my GP. Waiting until January would be very difficult.
take care there.
