Association of aneurysmatic subarachnoid hemorrhage rate with environmental changes or emotional bursts

INTRODUCTION: In the present letter we share the results of an analysis of more than 140,000 non traumatic arterial subarachnoid hemorrhages whereas the majority of them is expected to be after aneurysm rupture, in which we investigate a possible correlation of climatic changes and emotional bursts as correlating factors for such a rupture. METHODS: We obtained the daily number of SAH from 2006 to 2018 for males and females from the German National statistics agency. The ICD codes provided to us were I60.1-I60.7, which are SAHs originating from intracranial arteries and excluding traumatic SAH and other not specified SAH. RESULTS: An increase of mean SAH per day could be seen in winter compared to summer and family events seemed to have a protective effect against aneurysmal SAH. Additionally 6.55 more women per day suffer an SAH compared to men. CONCLUSION: There is a statistical significant higher risk of aneurysm ruptures in winter and in females, and a statistical lower number in Mother’s day.
