Role of bioclimate conditions on cerebral aneurysm rupture in Brittany region

Abstract : Aneurysmal subarachnoid hemorrhage (SAH) is a sudden event responsible of significant morbidity and mortality. Several studies suggest a role of climate in SAH occurrence. The aim of this study is to determine the impact of climate parameters and moon cycle on SAH occurrence in Brittany. All adult patients hospitalized for SAH, between 2011 and 2012, were included. The meteorological variables, changes in these variables, the moon phase and the tidal coefficient were compared between days with and without SAH. The minimum temperature was significantly lower on days with SAH (7.7°C vs 8.3°C, p = 0,039) and temperature drop between two days was significantly higher for days with SAH (8.6°C vs 7 , 9°C, p = 0,0095). If the temperature dropped to 8°C or more between 2 days, the SAH risk increased by 35%. There was no effect of other variables. Low temperatures and the temperature drop are associated with SAH occurrence.
