Studying Effects of Weather Parameters on Acute Stroke: Considering the Contribution of “Risk Factors” and “Triggering Factors” Together

A recently published article in the Journal of Stroke and Cerebrovascular Diseases regarding the effect of season and atmospheric temperature variation in acute stroke by Gomes et al has drawn our attention. The authors studied the variation in the incidence of stroke hospitalizations across seasons and with short-term temperature change in a tropical setting by examining 651 consecutive stroke events occurred during the period of August 1, 2005, through July 31, 2006. The study illustrated that sudden declines in the minimum temperature over the 5-10 days before the event were associated with a 20%-30% higher incidence of stroke. However, the role of conventional risk factors for stroke such as hypertension, diabetes, etc., was not considered in this study, although all the analyses were appropriately carried out stratified by sex, age (
