One approach is your doctors' approach of trying aspirin, and
as long as you do not have a recurrence of stroke
, to just leave you on the aspirin. If you do have a recurrence, the next step would be to add another blood thinner in addition to aspirin. This is a sensible, common sense approach that has been used for many years. The only problem with this is that if the next stroke is a large one, it could leave you with significant disability, or worse.
