We found that cerebral aneurysm rupture most frequently occurs in winter and spring, and less frequently — in summer. The highest number of ruptured cerebral aneurysms happens in the morning, between 8 am and 12 pm. The data regarding meteorological factors' effect on the risk of cerebral aneurysm rupture are conflicting. However, it should be noted that changes in barometric pressure and falling temperature are associated with the risk of aneurysmal subarachnoid hemorrhage.</p></abstract><trans-abstract xml:lang="ru"><p>Представлен обзор современной литературы о влиянии сезонных, метеорологических и циркадных факторов на риск разрыва церебральных аневризм. Выявлено, что наиболее часто разрыв церебральных аневризм случается в зимнее и весеннее время года, наиболее редко — летом. Максимальное количество случаев аневризматического субарахноидального кровоизлияния происходит утром, между 8 и 12 ч. Данные по влиянию метеорологических факторов на риск разрыва церебральных аневризм противоречивы, при этом можно отметить, что колебания атмосферного давления и снижение температуры воздуха сопряжены с риском аневризматического субарахноидального кровоизлияния.</p></trans-abstract><kwd-group xml:lang="en"><kwd>subarachnoid hemorrhage</kwd><kwd>aneurysm</kwd><kwd>risk factors</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>субарахноидальное кровоизлияние</kwd><kwd>аневризма</kwd><kwd>факторы риска</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Inagawa T., Takechi A., Yahara K. et al.
