Abstract
BACKGROUND AND PURPOSE To understand the association of sex-specific race and ethnicity on the short-term outcomes of initial and recurrent ischemic stroke events. METHODS Using the Paul Coverdell National Acute Stroke Program from 2016-2020, we examined 426,062 ischemic stroke admissions from 629 hospitals limited to non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic patients. We performed multivariate logistic regression analyses to assess the combined effects of sex-specific race and ethnicity on short-term outcomes for acute ischemic stroke patients presenting with initial or recurrent stroke events. Outcomes assessed include rates of in-hospital death, discharge to home, and symptomatic intracranial hemorrhage (sICH) after reperfusion treatment. RESULTS Among studied patients, the likelihood of developing sICH after reperfusion treatment for initial ischemic stroke was not significantly different. The likelihood of experiencing in-hospital death among patients presenting with initial stroke was notably higher among NHW males (AOR 1.59 [95 % CI 1.46, 1.73]), NHW females (AOR 1.34 [95 % CI 1.23, 1.45]), and Hispanic males (AOR 1.57 [95 % CI 1.36, 1.81]) when compared to NHB females. Hispanic females were more likely to be discharged home when compared to NHB females after initial stroke event (AOR 1.32 [95 % CI 1.23, 1.41]). NHB males (AOR 0.90 [95 % CI 0.87, 0.94]) and NHW females (AOR 0.89 [95 % CI 0.86, 0.92]) were less likely to be discharged to home. All groups with recurrent ischemic strokes experienced higher likelihood of in-hospital death when compared to NHB females with the highest likelihood among NHW males (AOR 2.13 [95 % CI 1.87, 2.43]). Hispanic females had a higher likelihood of discharging home when compared to NHB females hospitalized for recurrent ischemic stroke, while NHB males and NHW females with recurrent ischemic stroke hospitalizations were less likely to discharge home. CONCLUSIONS Sex-specific race and ethnic disparities remain for short-term outcomes in both initial and recurrent ischemic stroke hospitalizations. Further studies are needed to address disparities among recurrent ischemic stroke hospitalizations.

Ann Indian Acad Neurol 2024; 27:165-171. [PMID: 38751933 PMCID: PMC11093158 DOI: 10.4103/aian.aian_1091_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 03/01/2024] [Accepted: 03/03/2024] [Indexed: 05/18/2024] Open
Abstract
Background Only a small percentage of patients with acute stroke are currently eligible for thrombolysis, partly due to severe delays in hospital arrival. We had previously conducted the first regional study to assess the factors delaying acute stroke care in India. The present study aims to understand and describe in depth the variables associated with prehospital delay among patients admitted with an acute ischemic stroke. Methods Data were prospectively collected by conducting an in-depth interview of 470 acute ischemic stroke patients and their bystanders, aged above 18 years, presenting to the Department of Emergency Medicine, Jubilee Mission Medical College and Research Institute, Thrissur. Patients who arrived within 4.5 h of symptom onset were considered as "early arrival" and those who arrived after 4.5 h were considered as "delayed arrival." Univariate and multivariate analyses were undertaken to determine associations between variables of interest and delays to hospital presentation. Results Of the 470 patients who met the inclusion criteria, 73 patients reached within 4.5 h (15.5%), whereas 397 patients arrived after 4.5 h. The mean age of acute stroke patients who reached within 4.5 h was 63 ± 13.7 years, whereas the mean age of those who reached after 4.5 h was 63 ± 12.1 years. Binary logistic regression performed to quantify the associations of prehospital factors showed an increased risk of prehospital delay among individuals with lack of awareness (odds ratio [OR] = 5.16 [3.040-8.757], P < 0.001), followed by those for whom a vehicle was not available at the site of event (OR = 3.745 [1.864-7.522], P < 0.001). Within the predefined socioeconomic strata, compared to lower class, upper middle class had less risk (OR = 0.135 [0.018-1.035], P = 0.054), whereas the distance from first medical contact to emergency department contributed moderate risk (OR = 1.071 [1.028-1.116], P < 0.001) for prehospital delay. Conclusions Health promotion techniques that increase public knowledge about the early signs of stroke, transferring patients directly to hospitals with thrombolysis capabilities, and making ambulance services more widely available are appropriate measures to reduce prehospital delay.

Sex Differences in Functional Outcomes Following Endovascular Treatment for Acute Ischemic Stroke. Can J Neurol Sci 2023; 50:174-181.

Abstract
BACKGROUND Sex disparities have been reported across many aspects of acute ischemic stroke (AIS) care; however, there is a relative paucity of research examining sex differences in outcomes following endovascular treatment (EVT). Some studies report worse functional independence for females following EVT. Few, if any of these studies account for differences in age, baseline function, and comorbidity burden. This retrospective cohort study aimed to assess for sex differences in functional outcomes following EVT by comparing 90-day modified Rankin Scale (mRS) of males and females while controlling for baseline function and comorbidity burden. METHODS Baseline demographic and clinical data, and stroke severity were compared for 230 consecutive patients undergoing EVT for AIS between October 2014 and July 2019 at a tertiary stroke centre in Toronto, Canada. Effect of sex on likelihood of functional independence post-EVT was assessed using regression analysis with and without correction for age, baseline mRS, and Charlson Comorbidity Index (CCI). RESULTS Females undergoing EVT for AIS were older (75 ± 13 vs. 66 ± 15, p < 0.0001), with worse clinical and functional baselines. Unadjusted, males were more functionally independent (90-day mRS < 3) [OR = 1.831, 95%CI 1.082-3.098]. After controlling for age, baseline mRS and CCI, there was no difference between groups [OR 1.21, 95%CI 0.61-2.37]. CONCLUSIONS This study provides evidence that prior findings of sex disparities in function after EVT may be accounted for by differences in age, baseline clinical status and functional independence between males and females when a comprehensive measure of comorbidity burden is utilized.

Abstract
INTRODUCTION Systematic reviews and meta-analyses have synthetized the existing knowledge on sex-differences for the risk of stroke, the most recent ones highlighting an increased risk of stroke for women. However, whether there are sex differences in post stroke treatment in real world setting is not known. We therefore conducted a systematic review on this subject. MATERIAL AND METHODS All observational studies on sex-differences in poststroke drug use published until 20/04/2021 were identified from PubMed and Scopus. Articles were selected and assessed by two independent readers; a third resolved disagreements. Data extraction was performed using a standardized form; articles quality was assessed using the STROBE guidelines. The study is registered on PROSPERO: CRD42021250256. RESULTS Of the 604 identified articles, 33 were included. Most were published before 2015 and presented methodological limitations. These limitations differentially affected studies with statistically significant and non-significant results, questioning the reliability of conflicting results. The exploration of sex-differences in drug use varied between therapeutic classes (articles focusing on thrombolytics: 25; antithrombotics: 23; on antihypertensive: 13; lipid-lowering drugs: 9). After stroke, women were found less likely to be prescribed antithrombotics in 48% of the articles investigating this class, and lipid-lowering drugs in 56%. Thirty-one percent of the studies concerning antihypertensive drugs reported the opposite. DISCUSSION/CONCLUSION In women, a lack of use of antithrombotics and lipid-lowering drugs after stroke seem to emerge from this review. Conflicting results regarding sex-differences might relate to methodological limitations in studies with no statistical differences, and advocate for the conduct of newer and more comprehensive research.

Abstract
BACKGROUND In 2015, endovascular therapy (EVT) for large vessel occlusions became standard of care for acute ischemic stroke. Lower utilization of IV alteplase has been reported in women, but whether sex differences in EVT use in the United States exists has not been established. METHODS We identified all acute ischemic stroke discharges from Get With The Guidelines-Stroke hospitals between 2012 and 2019 who were potentially eligible for EVT, based on National Institutes of Health Stroke Scale score ≥6 and arrival <6 hours, according to 2018 American Heart Association/ASA guidelines. Multivariable regression analyses were used to determine the association between sex and EVT utilization, and outcomes (including mortality, discharge home, functional status) after EVT. Separate analyses were conducted for the 2 time periods: 2012 to 2014, and 2015 to 2019. RESULTS Of 302 965 patients potentially eligible for EVT, 42 422 (14%) received EVT. Before 2015, EVT treatment rates were 5.3% in women and 6.6% in men. From 2015 to 2019, treatment rates increased in both sexes to 16.7% in women and 18.5% in men. The adjusted odds ratio for EVT in women compared with men was 0.93 (95% CI, 0.87-0.99) before 2015, and 0.98 (95% CI, 0.96-1.01) after 2015. There were no significant sex differences in outcomes except that after 2015, women were less able to ambulate at discharge (adjusted odds ratio, 0.95 [95% CI, 0.95-0.99]) and had lower in-hospital mortality (adjusted odds ratio, 0.93 [95% CI, 0.88-0.99]). CONCLUSIONS EVT utilization has increased dramatically in both women and men since EVT approval in 2015. Following statistical adjustment, women were less likely to receive EVT initially, but after 2015, women were as likely as men to receive EVT. After EVT, women were more likely to be disabled at discharge but less likely to experience in-hospital death compared with men.

Abstract
Neurovascular units (NVUs) are basic functional units in the central nervous system and include neurons, astrocytes and vascular compartments. Ischemic stroke triggers not only neuronal damage, but also dissonance of intercellular crosstalk within the NVU. Stroke is sexually dimorphic, but the sex-associated differences involved in stroke-induced neurovascular dysfunction are studied in a limited extend. Preclinical studies have found that in rodent models of stroke, females have less neuronal loss, stronger repairing potential of astrocytes and more stable vascular conjunction; these properties are highly related to the cerebroprotective effects of female hormones. However, in humans, these research findings may be applicable only to premenopausal stroke patients. Women who have had a stroke usually have poorer outcomes compared to men, and because stoke is age-related, hormone replacement therapy for postmenopausal women may exacerbate stroke symptoms, which contradicts the findings of most preclinical studies. This stark contrast between clinical and laboratory findings suggests that understanding of neurovascular differences between the sexes is limited. Actually, apart from gonadal hormones, differences in neuroinflammation as well as genetics and epigenetics promote the sexual dimorphism of NVU functions. In this review, we summarize the confirmed sex-associated differences in NVUs during ischemic stroke and the possible contributing mechanisms. We also describe the gap between clinical and preclinical studies in terms of sexual dimorphism.

Abstract
Ischemic stroke is a devastating health problem, affecting approximately 800,000 patients in the US every year, making it the leading cause of combined death and disability in the country. Stroke has historically been thought of as predominantly impacting men, however it is becoming increasingly clear that stroke affects women to a greater degree than men. Indeed, women have worse outcomes compared to men following ischemic stroke. Recent clinical advances have shown great promise in acute stroke therapy, with the use of mechanical endovascular thrombectomy (with and without recombinant tissue plasminogen activator; rtPA) greatly improving outcomes. This observation makes it clear that removal of clots and reperfusion, either mechanically or pharmacologically, is critical for improving outcomes of patients following acute ischemic stroke. Despite these promising advances, long-term neurological sequelae persist in the post-stroke population. This review focuses on mechanisms of thrombosis (clot formation) as it pertains to stroke and important sex differences in thrombosis and responses to treatment. Finally, we describe recent data related to new therapeutic approaches to thrombolysis, with a particular focus on von Willebrand Factor (vWF).

Abstract
BACKGROUND AND OBJECTIVES In patients with ischemic stroke (IS), IV alteplase (tissue plasminogen activator [tPA]) and endovascular thrombectomy (EVT) reduce long-term disability, but their utilization has not been fully optimized. Prior research has also demonstrated disparities in the use of tPA and EVT specific to sex, race/ethnicity, socioeconomic status, and geographic location. We sought to determine the utilization of tPA and EVT in the United States from 2016-2018 and if disparities in utilization persist. METHODS This is a retrospective, longitudinal analysis of the 2016-2018 National Inpatient Sample. We included adult patients who had a primary discharge diagnosis of IS. The primary study outcomes were the proportions who received tPA or EVT. We fit a multivariate logistic regression model to our outcomes in the full cohort and also in the subset of patients who had an available baseline National Institutes of Health Stroke Scale (NIHSS) score. RESULTS The full cohort after weighting included 1,439,295 patients with IS. The proportion who received tPA increased from 8.8% in 2016 to 10.2% in 2018 (p < 0.001) and who had EVT from 2.8% in 2016 to 4.9% in 2018 (p < 0.001). Comparing Black to White patients, the odds ratio (OR) of receiving tPA was 0.82 (95% confidence interval [CI] 0.79-0.86) and for having EVT was 0.75 (95% CI 0.70-0.81). Comparing patients with a median income in their zip code of ≤$37,999 to >$64,000, the OR of receiving tPA was 0.81 (95% CI 0.78-0.85) and for having EVT was 0.84 (95% CI 0.77-0.91). Comparing patients living in a rural area to a large metro area, the OR of receiving tPA was 0.48 (95% CI 0.44-0.52) and for having EVT was 0.92 (95% CI 0.81-1.05). These associations were largely maintained after adjustment for NIHSS, although the effect size changed for many of them. Contrary to prior reports with older datasets, sex was not consistently associated with tPA or EVT. DISCUSSION Utilization of tPA and EVT for IS in the United States increased from 2016 to 2018. There are racial, socioeconomic, and geographic disparities in the accessibility of tPA and EVT for patients with IS, with important public health implications that require further study.

Abstract
BACKGROUND Previous research has revealed sex-related differences in outcomes for people admitted to hospitals for ischemic stroke. We aimed to analyse the incidence, use of invasive procedures and in-hospital outcomes of ischemic stroke in Spain (2016-2018) using the Spanish National Hospital Discharge Database. We sought sex-related differences in incidence and in-hospital outcomes over time. METHODS We estimated the incidence of ischemic stroke in men and women. We analysed comorbidities (Charlson's comorbidity index, cardiovascular risk factors, alcohol abuse and atrial fibrillation), procedures (mechanical ventilation, endovascular thrombectomy and thrombolytic therapy) and outcomes. We matched each woman with a man with identical age, type of ischemic stroke and year of hospitalisation. We built Poisson regression models to obtain adjusted incidence rate ratios (IRRs). We tested in-hospital mortality (IHM) with logistic regression analyses. RESULTS Ischemic stroke was coded in 172 255 patients aged ≥35 years (92 524 men 53.7%). Men showed higher incidence rates (216.9 vs. 172.3/105 ; P < .001; IRR = 1.57 (95% CI:1.55-1.59) than women. After matching, the use of endovascular thrombectomy (5.1% vs. 4.0%; P < .001) and thrombolytic therapy (7.6% vs. 6.8%; P < .001) was higher among women. IHM was significantly higher in women than in matched men (11.2% vs. 10.4%; P < .001). Women had a lower IHM than matched men when endovascular thrombectomy (9.4% vs. 12.1%; P = .001) or thrombolytic therapy (6.7% vs. 8.3%; P = .003) was coded. Patients of both sexes admitted for ischemic stroke who received thrombolytic therapy had lower IHM (OR = 0.76; 95% CI:0.68-0.85 among men; and OR = 0.58; 95% CI:0.52-0.64 among women), but endovascular thrombectomy was associated with a lower IHM only among women (OR = 0.58; 95% CI:0.51-0.66). After multivariable adjusting, women admitted to the hospital for ischemic stroke had a significantly higher IHM than men (OR = 1.16; 95% CI:1.12-1.21). CONCLUSION Men had higher incidence rates of ischemic stroke than women. Women more often underwent thrombolytic therapy and endovascular thrombectomy but had a higher IHM.

Abstract
Males and females possess distinct biological differences that manifest in diverse risk profiles for acute and chronic diseases. A well-documented example of this is ischemic stroke. It has been demonstrated that older females have greater prevalence of, and worse outcome after, ischemic stroke than do males and younger females. Loss of estrogen after menopause is heavily implicated as a contributing factor for this phenomenon; however, there is mounting evidence to suggest that certain risk factors tend to occur more often in older females, such as hypertension and atrial fibrillation, while others more adversely affect females than they do males, such as diabetes and smoking. Sex-specific risk factors, such as oral contraceptive use and menopause, could also contribute to the discrepancy in stroke prevalence and outcome. Additionally, there is evidence to suggest that females tend to present with more nontraditional symptoms of acute stroke than do males, making it more difficult for clinicians to correctly identify the occurrence of a stroke, which may delay the administration of thrombolytic intervention. Finally, certain sociodemographic factors, such as the fact that females were more likely to live alone prior to stroke, may contribute to poorer recovery in females. This review will explore the various co-morbidities and sociodemographic factors that contribute to the greater prevalence of and poorer outcome after stroke in older females and will highlight the critical need for considering sex as a predisposing biological variable in stroke studies.

Abstract
Sex dimorphisms are important factors that influence the outcomes after ischemic stroke, which include basic health status, cerebrovascular anatomy, hormone levels, and unique factors such as pregnancy and menopause. It is widely recognized that male and female respond differently to stroke. Women aged 45–74 years old showed a lower risk of stroke incidence compared to age-matched man. This kind of protection is lost with aging. Hence, there is increasing requirement to get a more comprehensive understanding of sex-based factors to stroke on stroke incidence, symptoms, and treatments. This review focuses on sex-specific mechanisms in response to stroke based on experimental studies and highlights recent findings in clinical studies including sex-differential evaluation and outcomes of stroke. Sex-based personalized medicine should be promising in stroke therapies.

Abstract
INTRODUCTION Sex-based medicine, which can be defined as the process of understanding the inherent differences in disease pathophysiology and response to medications that exist between the sexes, seems like a necessary step in the movement towards personalized medicine. While there are strict guidelines for weight-based dosage of pediatric medications, similar guidelines do not exist for the treatment of adults, despite prominent biologic differences between the sexes. The lack of individualization is of particular importance in the treatment of adult patients in the emergency department (ED), because it can determine the trajectory of a patient's stay at the hospital. OBJECTIVES This review was conducted to better understand the need for and possible benefits of altering drug dosing guidelines for different categories of medications in the ED. PubMed, SCOPUS, and Google Scholar were queried using a combination of the keywords "gender differences," "sex differences," "treatment," and "emergency". Abstracts, unpublished data, and duplicate articles were excluded. DISCUSSION In considering some of the most common causes of ED visits, the majority of diseases demonstrate differences in morbidity and mortality between female and male patients, despite similar treatment regimens. These differences can be attributed to variations in drug pharmacodynamics and pharmacokinetics, which may be affected by sex-based biologic variations in body mass index and body composition, and physiologic variations such as hormonal changes, menstruation, pregnancy, and lactation. Regardless of the mechanism of these differences, there is overwhelming evidence that universal drug dosing results in suboptimal outcomes for both male and female patients. CONCLUSIONS Female sex is a risk factor for clinically significant adverse drug reactions, which range from cutaneous reactions to major bleeding, and can have long-standing implications on patient outcomes. However, future studies are needed to understand the exact pathophysiology of these sex differences, after controlling for potential confounding factors such as demographic differences and provider bias in treatment.

Abstract
Background and Purpose- To date, there is still uncertainty about age and sex differences in access to stroke unit treatment and use of intravenous thrombolysis (IVT), while age and sex differences have not been investigated for the new treatment option of mechanical thrombectomy (MT). We, therefore, undertook a complete nationwide analysis of all hospitalized ischemic stroke patients in Germany from 2013 to 2017. Methods- We used the nationwide administrative database of the German Federal Statistical Office and investigated access to stroke unit treatment, IVT, MT, and in-hospital mortality. Patients were subdivided into 6 predefined age groups (20-44, 45-59, 60-69, 70-79, 80-89, and >90 years). Pooled overall and age group estimates were calculated using the random-effects model. To evaluate potential sex disparities, we estimated odds ratios (ORs) with 95% CIs. Results- A total of 1 112 570 patients were hospitalized for first or recurrent ischemic stroke from 2013 to 2017. Overall, stroke unit treatment increased significantly from 66.8% in 2013 to 73.5% in 2017, as did IVT (from 12.4% to 15.9%) and MT (from 2.4% to 5.8%; all P<0.001). Although the difference became smaller over time, patients ≥80 years of age still received significantly less often treatments. Men of all age groups had a significantly higher probability receiving stroke unit treatment (OR, 1.11; 95% CI, 1.09-1.12) and lower in-hospital mortality (OR, 0.91; 95% CI, 0.89-0.93). No disparity was observed in the use of IVT (OR, 1.00; 95% CI, 0.98-1.01), while women of all ages were treated more often with MT (OR, 1.26; 95% CI, 1.22-1.30). Conclusions- Access to stroke unit treatment has to be increased in both older patients and women of all ages. While there was no sex difference in IVT use, it is important to further investigate the significantly higher frequency of MT in women with ischemic stroke irrespective of age.

Abstract
Despite the immeasurable burden on patients and families, no effective therapies to protect the CNS after an acute injury are available yet. Furthermore, the underlying mechanisms that promote neuronal death and functional deficits after injury remain to be poorly understood. The prevalence, age of onset, pathophysiology, and symptomatology of many CNS insults differ significantly between males and females. In the case of stroke, younger males tend to show a higher risk than younger females, while this trend reverses with age. Accumulating evidence from preclinical studies have shown that sex hormones play a crucial role in providing neuroprotection following ischemic stroke and other acute CNS injuries. Estrogen, in particular, exerts a neuroprotective effect by modulating the immune responses after injury. In addition, there exists a sexual dimorphism in cell death pathways between males and females that are independent of hormones. Meanwhile, recent studies suggest that microRNAs are critically involved in the sex-specific mechanisms of cell death. This review discusses the current knowledge on the contribution of sex and age to outcome after stroke. Implication of the interplay between these two factors on other CNS injuries (spinal cord injury and traumatic brain injury) from the experimental evidence were also discussed.

Abstract
With the greater availability of treatments for acute ischaemic stroke, including advances in endovascular therapy, personalised assessment of patients before treatment is more important than ever. Women have a higher lifetime risk of stroke; therefore, reducing potential sex differences in the acute stroke setting is crucial for the provision of equitable and fast treatment. Evidence indicates sex differences in prevalence and types of non-traditional stroke symptoms or signs, prevalence of stroke mimics, and door-to-imaging times, but no substantial differences in use of emergency medical services, stroke knowledge, eligibility for or access to thrombolysis or thrombectomy, or outcomes after either therapy. Women presenting with stroke mimics or non-traditional stroke symptoms can be misdiagnosed, which can lead to inappropriate triage, and acute treatment delays. It is essential for health-care providers to recognise possible sex differences in stroke symptoms, signs, and mimics. Future studies focused on confounders that affect treatment and outcomes, such as age and pre-stroke function, are also needed.

Abstract
OBJECTIVE To explore a 5-year comparison of disparities in intravenous t-PA (IV t-PA) use among acute ischemic stroke (AIS) patients based on race, gender, age, ethnic origin, hospital status, and geographic location. METHODS We extracted patients' demographic information and hospital characteristics for 2010 and 2014 from the New York Statewide Planning and Research Cooperative System (SPARCS). We compared disparities in IV t-PA use among AIS patients in 2010 to that in 2014 to estimate temporal trends. Multiple logistic regression was performed to compare disparities based on demographic variables, hospital designation, and geographic location. RESULTS Overall, there was approximately a 2% increase in IV t-PA from 2010 to 2014. Blacks were 15% less likely to receive IV t-PA compared to Whites in 2014, but in 2010, there was no difference. Patients aged 62-73 had lower odds of receiving IV t-PA than age group ≤61 in both 2010 and 2014. Designated stroke centers in the Lower New York State region were associated with reduced odds of IV t-PA use in 2010 while those located in the Upper New York State region were associated with increased odds of IV t-PA use in both 2010 and 2014, compared to their respective nondesignated counterparts. Gender, ethnic origin, and insurance status were not associated with IV t-PA utilization in both 2010 and 2014. CONCLUSION Overall IV t-PA utilization among AIS patients increased between 2010 and 2014. However, there are evident disparities in IV t-PA use based on patient's race, age, hospital geography, and stroke designation status.

Abstract
CONTEXT Lack of early stroke recognition and delays in seeking emergency care by persons experiencing a stroke severely limit acute treatment options. Sparse and sometimes conflicting evidence suggests sex differences in care-seeking behaviors in stroke, stroke knowledge, perceptions of stroke symptoms, and the importance of physical location at the time of stroke and of having a witnessed stroke. OBJECTIVE To explore specific sex-based differences in stroke presentation and associated care-seeking behaviors. DESIGN Descriptive study based on a convenience sample of 60 patients with stroke admitted to an academic medical center in Northern California. MAIN OUTCOME MEASURES Impact of the patient's sex on 1) time to presentation (early [≤ 4.5 hours] vs late [> 4.5 hours]); 2) perception of symptoms and clinical signs; 3) stroke knowledge and decision making; 4) physical location at the time of stroke; and 5) bystander presence and assistance with decision making. RESULTS There was a discrepancy between how patients perceive symptoms and their medical findings on physical examination. Although most patients had at least one sign or symptom associated with nationally used stroke recognition acronyms, both sexes delayed care because they did not perceive their symptoms as urgent. Early-presenting men were more likely to have a higher stroke severity score at admission, receive alteplase, arrive by Emergency Medical Services, and have a witnessed stroke. Both early- and late-presenting women reported more nonfocal symptoms than did men. CONCLUSION This study suggests that there are sex-based differences in symptom perception and care-seeking behavior in acute ischemic stroke.

Abstract
Biologic sex influences many variables that are important to brain health in general, and to stroke or cerebral ischemia in particular, such as general health status, cerebrovascular anatomy and function, unique risk factors such as pregnancy and preeclampsia, symptomatology, and therapeutic response. A more complete understanding of the scale and depth of sexual dimorphism in the brain and the role of more general sex-based factors is crucial to reducing the burden of stroke in women and men. This focused review highlights recent findings in stroke, including sex differences in epidemiology, risk factor reduction, comparative use of stroke therapeutics in both sexes, the importance of frailty in women, and the biologic basis for sex differences in stroke. Such findings show tremendous promise for the future of personalized medicine in stroke prevention and treatment.
