Any advise on lifestyle habits after a tia (transient ischemic attack)?

Ask your doc: The key to lifestyle changes may have to do with the underlying medical condition that may have caused increased risk for tia. Monitoring and treating blood pressure if it is high or diabetes is important. Healthy diet and exercise are important but before starting diet and exercise program it is wise to consult with doctor - avoid bad things like too much alcohol, and avoid cigarettes.

Healthy lifestyle: General recommendation is to control blood pressure, cholesterol levels, glucose levels (if diabetic), adhere to a healthy diet (mediterranean is great!), quit smoking and be physically active (at least 30 minutes per day 3 times a week).
