“…18-20 A case-crossover study showed a difference in seasonal variation between the sexes, with a higher risk of ischemic stroke in hotter seasons only in men. 21 These discordant results may be caused by the heterogeneity of subtypes of ischemic stroke. Because most studies on this theme had community-based designs, the analysis by detailed subtype, quantitative evaluation of neurological severity and functional outcome, and analysis of the hospital care process were often insuf-tion of emboligenic diseases principally using ECG monitoring in the stroke units, Holter monitoring, transthoracic echocardiography, and transesophageal echocardiography.…”

“…8,9 Ischemic stroke is one of the most prevalent causes for hospitalization and mortality in the Western world. 10,11 Risk factors include medical conditions (hypertension, diabetes mellitus, dyslipidemia, atrial fibrillation, sleep apnea, and others), lifestyle (smoking, physical activity), 12,13 and environmental factors (air temperature and air pollution [14][15][16][17][18] ). Ramadan associated changes such as poor drug therapy compliance; reduced glycemic control, and dehydration may temporarily contribute to stroke risk, yet such an increased stroke risk during Ramadan has not been reported.…”

BackgroundPrevious studies have not shown any significant effect on stroke incidence during Ramadan. We aimed to investigate the association between ischemic stroke incident hospitalizations and Ramadan, accounting for seasonality and temperature.Methods and ResultsThis retrospective cohort study included all patients admitted with acute ischemic stroke to Soroka University Medical Center from June 2012 to June 2016. We obtained daily mean temperatures and relative humidity rates from 2 monitoring stations in South Israel. We analyzed the association between stroke incidence and Ramadan month, adjusting for weekly temperature and seasonality using Poisson regression models. We compared the first versus the last Ramadan fortnight. We performed an effect specificity analysis by assessing stroke incidence in the non‐Bedouin population. We identified 4727 cases of ischemic stroke, 564 cases of which were Bedouin Arabs. Fifty‐one cases occurred during Ramadan. Ramadan was significantly associated with an increased risk for ischemic stroke (RR 1.48; 95% confidence interval, 1.04–2.09), mainly during the first fortnight (RR 1.73, 95% confidence interval, 1.13–2.66) when compared with non‐Ramadan periods. Mean weekly temperatures and the summer season were not associated with stroke incidence among Bedouin Arabs (RR 0.98; 95% confidence interval, 0.82–1.18 and RR 0.77; confidence interval 0.56–1.06 accordingly). Such association was not observed in the non‐Bedouin population.ConclusionThe Ramadan month, particularly in its first 2 weeks, is an independent and ethnicity specific risk factor for ischemic stroke hospitalizations among the Bedouin Arab fasting population.

“…Thirteen studies reported increasing risks for hospitalizations for stroke with higher ambient temperatures 29, 36, 44,46,50,56,e65-71 . Maximum temperatures were 12.9°C in one study 29 , 20-27°C in 5 studies 36,44,e65,69,70 , and >30°C in 5 studies 47,50,56,e66,71 . Temperatures were unspecified in two studies e67, 68 .…”

BackgroundClimate change, including global warming, is expected to cause poorer global health and a rise in the number of environmental refugees. As neurological disorders account for a major share of worldwide morbidity and mortality, climate change and global warming are also destined to alter neurological practice; however, to what extent and by which mechanisms is unknown. We aimed to collect the available information on the effects of ambient temperatures and human migration on the epidemiological and clinical manifestations of major neurological disorders.MethodsWe searched PubMed and Scopus from January 1, 2000 to November 30, 2020 for human studies published in English addressing the influence of ambient temperatures and human migration on Alzheimer’s and non-Alzheimer’s dementia, epilepsy, headache and migraine, multiple sclerosis, Parkinson’s disease, stroke, and tick-borne encephalitis (as a model disease for neuroinfections). The protocol was pre-registered at PROSPERO (2020 CRD42020147543).Results101 studies met inclusion criteria, but we were unable to identify a single study addressing how global warming and human migration will change neurological practice. Still, extracted data suggested multiple ways by which these aspects might alter neurological morbidity and mortality in the future.ConclusionSignificant heterogeneity exists across studies with respect to methodology, outcome measures, control of confounders and study design, but there is enough evidence to suggest climate change will affect the neurological practice of all major neurological disorders. Adequately designed studies to address this issue are urgently needed, which will require concerted efforts from the neurological community.
