Incidence of ischemic stroke and transient ischemic attack in young adults is rising. However, etiology remains unknown in 30–40% of these patients when current classification systems designed for the elderly are used. Our aim was to identify risk factors according to a pediatric approach, which might lead to both better identification of risk factors and provide a stepping stone for the understanding of disease mechanism, particularly in patients currently classified as “unknown etiology”. Risk factors of 656 young stroke patients (aged 18–50) of the FUTURE study were categorized according to the “International Pediatric Stroke Study” (IPSS), with stratification on gender, age and stroke of “unknown etiology”. Categorization of risk factors into ≥1 IPSS category was possible in 94% of young stroke patients. Chronic systemic conditions were more present in patients aged <35 compared to patients ≥35 (32.6% vs. 15.6%, p < 0.05). Among 226 patients classified as “stroke of unknown etiology” using TOAST, we found risk factors in 199 patients (88%) with the IPSS approach. We identified multiple risk factors linked to other mechanisms of stroke in the young than in the elderly . This can be a valuable starting point to develop an etiologic classification system specifically designed for young stroke patients.

IntroductionWorldwide, 2 million patients aged 18–50 years suffer a stroke each year, and this number is increasing. Knowledge about global distribution of risk factors and aetiologies, and information about prognosis and optimal secondary prevention in young stroke patients are limited. This limits evidence-based treatment and hampers the provision of appropriate information regarding the causes of stroke, risk factors and prognosis of young stroke patients.Methods and analysisThe Global Outcome Assessment Life-long after stroke in young adults (GOAL) initiative aims to perform a global individual patient data meta-analysis with existing data from young stroke cohorts worldwide. All patients aged 18–50 years with ischaemic stroke or intracerebral haemorrhage will be included. Outcomes will be the distribution of stroke aetiology and (vascular) risk factors, functional outcome after stroke, risk of recurrent vascular events and death and finally the use of secondary prevention. Subgroup analyses will be made based on age, gender, aetiology, ethnicity and climate of residence.Ethics and disseminationEthical approval for the GOAL study has already been obtained from the Medical Review Ethics Committee region Arnhem-Nijmegen. Additionally and when necessary, approval will also be obtained from national or local institutional review boards in the participating centres. When needed, a standardised data transfer agreement will be provided for participating centres. We plan dissemination of our results in peer-reviewed international scientific journals and through conference presentations. We expect that the results of this unique study will lead to better understanding of worldwide differences in risk factors, causes and outcome of young stroke patients.

Abstract Background Etiologies of acute ischemic stroke in young adults are heterogeneous. Middle cerebral artery (MCA) stenosis is a common finding in Asians which may be an important cause of stroke in young adults. However, studies of stroke in young Asian populations are rare. Our study was to investigate the prevalence and outcome of young stroke patients with MCA stenosis in Chinese populations. Methods Young patients with MCA territory infarction between January 2013 and September 2018 were retrospectively recruited. Subjects were defined as stenosis group (MCA stenosis ≥50%) and no-stenosis group (MCA stenosis<50% or no stenosis) by their MCA stenosis. For patients in stenosis group, they were categorized as uni-MCA stenosis subgroup and multiple stenosis subgroup. Demographic data, risk factors, imaging feature and complications were compared between groups. Prevalence of MCA stenosis and risk factor score (score ≥ 2 or 3) in different age groups were investigated. Modified Rankin Scale (mRS) was used for evaluating functional outcome at discharge (unfavorable outcome: 3–6). Binary logistic regression was performed to determine independent risk factors of unfavorable outcome. Results Two hundred forty-nine young stroke patients were included in our study and 110 (44.2%) patients were defined as stenosis group. 55 (50%) patients were categorized as uni-MCA stenosis subgroup and 55 (50%) were multiple stenosis subgroup. The most common traditional vascular risk factors included hypertension, hyperlipemia, smoking, hyperhomocysteinemia and alcohol consumption. Prevalence of risk factor score ≥ 2 or 3 increased with age, but not incidence of MCA stenosis. By TOAST classification, the most common etiologies were large-artery atherosclerosis (41.0%) and small vessel disease (33.7%). Compared with no-stenosis group, patients in stenosis group were more likely to have large territorial infarct, develop complications and have unfavorable outcome. No significant difference was found between patients in uni-MCA stenosis and multiple stenosis subgroups except history of stroke/TIA, risk factor score ≥ 3 and silent infarct. By logistic regression, hypertension (OR = 3.561; 95%CI, 1.494 to 8.492; p = 0.004), NIHSS scores at admission (OR = 1.438; 95%CI, 1.276 to 1.620; p = 0,000) and infarct size (p = 0.015) independently predicted unfavorable outcome. Conclusions Forty-four point two percent young Chinese adults with MCA territory infarction had MCA stenosis. Prevalence of MCA stenosis did not increase with age. Patients with MCA stenosis had worse clinical outcome, however, only hypertension, NIHSS scores at admission and infarct size were independent predictors.

The aim of this study is to show the subtype, risk factors and predictors of poor outcomes in young ischemic stroke patients. Materials and Methods: It is a prospective study where only young onset ischemic stroke patients are analyzed. 8% of total ischemic stroke sufferers were young adults; more prevalent in female (57.1%), with risk factors of smoking (47.6%) subtype cardio embolic (42.9%) was common. High NIHSS score was related to new event and correlation to mortality. Three month follow up showed MRS 2.86 ± 1.02. 57.1% of cases had significant disability (defined as MRS ≥ 3). There was a positive correlation of the cardio embolic subtype and the unclassified subtype to all three forms of poor outcomes, along with a positive correlation of the large artery atherothrombotic subtype to new events Recurrence of events (new stroke, sudden increase in symptoms and new TIAs) was observed in 14.3 %. Death was reported in 9.5% of cases.   Etiological diagnosis can be reached in majority of cases if an aggressive approach is maintained. This small scale study has provided an overview of the distribution of subtypes, risk factors and poor outcomes and their predictors. Cardiac diseases (esp. valvular disease) need to be taken more seriously to prevent cardio embolic strokes, while addressing other traditional risk factors to prevent the atherothrombotic subtypes.

Background: In about 30% of young stroke patients, no cause can be identified. In elderly patients, kidney dysfunction has been suggested as a contributing risk factor for mortality as well as stroke. There are hypotheses that novel non-traditional risk factors, like chronic inflammation and oxidative stress, are involved in chronic kidney disease, affecting the cerebral microvasculature that would in turn lead to stroke. Our objective is to investigate the influence of kidney dysfunction on long-term mortality and incident vascular events after stroke in young adults aged 18 through 50 and if this relationship would be independent of other cardiovascular risk factors. Methods: We prospectively included 460 young stroke patients with an ischemic stroke or transient ischemic attack admitted to our department between January 1, 1980 and November 1, 2010. Follow-up was done between 2014 and 2015. Estimated glomerular filtration rate (eGFR) was calculated from baseline creatinine levels and was divided in 3 subgroups: eGFR <60, 60-120 and >120 ml/min/1.73 m2. Cox proportional hazard models were used to determine the effect of kidney dysfunction on mortality and incident vascular events, adjusting for cardiovascular risk factors. Results: An eGFR <60 (HR 4.6; 95% CI 2.6-8.2) was associated with an increased risk of death and an increased risk of incident stroke (HR 4.1; 95% CI 1.9-9.0) independent of cardiovascular risk factors, but it was not associated with other vascular events. The point estimate for the 15-year cumulative mortality was 70% (95% CI 46-94) for patients with a low eGFR, 24% (95% CI 18-30) for patients with a normal eGFR and 30% (95% CI 12-48) for patients with a high eGFR. The point estimate for the 15-year cumulative risk of incident stroke was 45% (95% CI 16-74) for patients with a low eGFR, 13% (95% CI 9-17) for patients with a normal eGFR and 8% (95% CI 0-18) for patients with a high eGFR. Conclusions: Kidney dysfunction is related to long-term mortality and stroke recurrence, but not to incident cardiovascular disease, on average 11 years after young stroke. This warrants a more intensive follow-up of young stroke patients with signs of kidney dysfunction in the early phase. In addition, the clear association between kidney dysfunction and incident stroke seen in our young stroke population might be a first step in the recognition of kidney dysfunction as a new risk factor for the development of stroke at young age. Also, it can lead to new insights in the etiological differences between cardiovascular and cerebrovascular disease.

Objectives. Reports on young patients with ischemic stroke from Eastern Europe have been scarce. This study aimed to assess risk factors and etiology of first-ever and recurrent stroke among young Estonian patients. Methods. We performed a retrospective study of consecutive ischemic stroke patients aged 18–54 years who were treated in our two hospitals from 2003 to 2012. Results. We identified 741 patients with first-ever stroke and 96 patients with recurrent stroke. Among first-time patients, men predominated in all age groups. The prevalence of well-documented risk factors in first-time stroke patients was 83% and in the recurrent group 91%. The most frequent risk factors were hypertension (53%), dyslipidemia (46%), and smoking (35%). Recurrent stroke patients had fewer less well-documented risk factors compared to first-time stroke patients (19.8 versus 30.0%, P=0.036). Atrial fibrillation was the most common cause of cardioembolic strokes (48%) and large-artery atherosclerosis (LAA) was the cause in 8% among those aged <35 years. Compared to first-time strokes, recurrent ones were more frequently caused by LAA (14.3 versus 24.0%, P=0.01) and less often by other definite etiology (8.5 versus 1.0%, P=0.01). Conclusions. The prevalence of vascular risk factors among Estonian young stroke patients is high. Premature atherosclerosis is a cause in a substantial part of very young stroke patients.

Background: Stroke is an important cause of disability among adults and is one of the leading causes of death worldwide. Strokes in young adults can have a significant impact on the affected individuals, their families and societies in general as the affected patients are in the economically productive period of their lives.This study was aimed to find out the demographic profile and explore the associated risk factors of the first-ever ischemic stroke of young adults.Methods: This retrospective study reviewed the records of 64 patients, age 18-49 years, ischemic stroke patients consecutively admitted in the Neurology department, BIRDEM General Hospital during the period January 2016 to June 2017. Study variables included hematological and biochemistry investigations and radiological and imaging findings. Stroke sub-typing was done following to TOAST criteria. Data of follow-up data at 3 month were also included. Data were expressed as number (percent) and managed by SPSS for Windows Version 15.Results: Of the 634 patients diagnosed as acute ischemic stroke 64 (9.90%) were in the 18-49 (yr) age range and the majority (55.4%) were male. Stroke was more common (47 out of 54) among the 31-49 years category as compare with the <30 years category. Stroke patients presented with diabetes mellitus(87.03%),arterial hypertension (44.4%), dyslipidemia (23.5%) and cigarette smoking (31.48%). Family history of stroke was present in 33.5% cases. Ten (6.51%) patients showed hypercoagualable state.Small vessel occlusion (SVO) found in 48.40% cases followed by large artery atherosclerosis (21.86%).Patients with SVO stroke presented with lacunar syndromes and lesions in Basal ganglia(12.1%),Thalamus(6.6%), Subcortical region (0.9%),Internal capsule (20.0%)and brain stem(11.3%). Thrombolysis was not done in any of patients. Most of the patients were on an anti-platelet treatment and majority (85.4%) receiving aspirin alone. Strokes left 48(75.5%)patients with moderate to moderately severe disability on discharge from the hospital.Mortality was lower (6.3%) and had good recovery 35 (54.6%).Conclusion: Ischemic stroke in the young adults accounted for 9.90% of the hospital admission with stroke. Those suffered from ischemic stroke had presence of modifiable risk factors. Predominance of SVO among them not only indicated stroke etiology but also predicted good short term prognosis.Birdem Med J 2018; 8(2): 138-144
