Hi! I am a 46 yr old Asian man, who has a history of High Blood Pressure, abnormal EKG w/Left Ventricular Atrophy, Diabetes which has since been treated with weight loss, so no insulin and no pills, a thyroid condition, and depression/bi-polar disorder. A few years ago, I was working driving a bus and suddenly I could not remember a thing. I had no idea where I was or who I was, why I was driving a bus or where I was going and why. This last for about 10 seconds and then gradually I seemed to regain my senses and the panic subsided and I just as suddenly it seems I remembered everything. This has only happened once, but it has troubled me ever since. Can someone tell me if perhaps I had a stroke or mini or silent heart attack? If I did, since this happened about 2 1/2 years ago, is there any point in getting tested for this? Is there even a way to tell if I ever had a stroke? Any advice would be helpful.
