I read your question carefully and I understand your concern. Vertigo is a symptom, unfortunately it doesn t say much about what the doctors thought to have been the cause. It would also have been useful to know some more details about your age, weight, lifestyle, prior medical history, family medical history to evaluate the likelihood of it being a stroke. Whether I can exclude with certainty for it to have been a transient ischemic attack, a subtype of stroke....no I can not do it with certainty. But I can say that if you are a young person, without any other medical condition, a stroke is little likely to be the cause of your vertigo episode, other causes such as inner ear issues are much more probable. Wishing you good health
