Spring is on its way. It’s a time of renewal, blossoming trees, and apparently stroke. In this study, stroke risk was highest in March, April and May, regardless of people’s known risk factors. Now, I hate to be a cynic, but a lot of these types of studies sound so bogus. You can take any random collection of events, and they can by happenstance fall into some sort of pattern. Presto – you have a “trend.” The key to there being any validity to the study centers on the idea that blood pressure may vary with climate.
