Hello, Its a little difficult to piece together all the information in your question due to the language constraints. But let me allay some of your fears. I guess you mean TIAs when you write TSI? Im sure your headaches can be controlled once the cause is ascertained in the Stroke Clinic. Dont worry too much about your memory problems right now as it can be evaluated later when your current problems are taken care of. Many a times when we are stressed and not paying attention at what we are doing memory seems much worse than what it actually is. The Vision problem needs closer evaluation and im sure at the stroke clinic they will be able to give you appropriate explanations for all your complaints. Meanwhile Clopidogrel should help you.Probably you might need statins and other medications. Also please know that you should be able to return to work gradually and what we usually see in practise is people who are strong willed and calm make quicker recovery than others.Take Care. Hope this helps
