Testosterone supplementation has increased in recent years for both treatment of hypogonadism and recreational use. Strokes in young adults have similarly increased with a larger proportion of patients in this age group having a stroke due to early onset of cardiovascular risk factors or unrelated to conventional risks. Hormonal treatments are associated with increased stroke risk amongst women, with some studies indicating an increase in stroke risk as high as 40% when compared to non-users. However, less is known about male sex hormones and risks associated with increased stroke. Limited data evaluates the relationship between testosterone supplementation and stroke in young adults. In this review, we analyze the literature and plausible underlying pathophysiological mechanisms associated with increased risks in patients using exogenous testosterone. Furthermore, we highlight the gaps in research about safety and long-term effects on young patients. [ABSTRACT FROM AUTHOR]

Background and purpose: The weight of outcome predictors in acute ischemic stroke (AIS) patients older than 60 years is not necessarily mirrored in the younger population, posing the question of whether outcome determinants specific for the latter might vary. Very few data are available on predictors of outcome in young AIS patients receiving endovascular treatment (EVT). Methods: We analyzed data for patients aged between 16 and 55 years from the Italian Registry of Endovascular Treatment in Acute Stroke. We divided our population into patients <45 years old and patients aged between 45 and 55 years. After testing the differences between groups in terms of 90‐day modified Rankin Scale (mRS) 0–2, mortality, and symptomatic intracranial hemorrhage, we looked for predictors of poor outcome (mRS 3–6), death, and symptomatic intracerebral hemorrhage in the two groups. Results: A total of 438 patients younger than 45 years and 817 aged 45–55 years were included; 284 (34.8%) patients aged 45–55 years and 112 (25.6%) patients younger than 45 years old showed poor 90‐day functional outcome (p = 0.001). Predictors of poor outcome in the older group were baseline National Institutes of Health Stroke Scale (NIHSS; p < 0.001), diabetes (p = 0.027), poor collateral status (p = 0.036), and groin puncture‐to‐recanalization time (p = 0.010), whereas Thrombolysis in Cerebral Infarction (TICI) 2b–3 had an inverse association (p < 0.001). Predictors of poor outcome in patients younger than 45 years were baseline NIHSS (p < 0.001) and groin puncture‐to‐recanalization time (p = 0.015), whereas an inverse association was found for baseline Alberta Stroke Program Early CT Score (p = 0.010) and TICI 2b–3 (p < 0.001). Conclusions: Approximately one third of young adults treated with EVT do not reach a good functional outcome. Fast and successful recanalization, rather than common risk factors, has a major role in determining clinical outcome. [ABSTRACT FROM AUTHOR]

Background and purpose: Incidence of ischemic stroke in young adults has been steadily increasing over the past 20 years. One hypothesis to explain this phenomenon is the increase in the use of illicit drugs, including cannabis. However, the mechanisms and the clinical presentation of ischemic stroke associated with cannabis use are unclear. The objective of this study was to describe the phenotype of ischemic stroke in cannabis users compared to nonusers among a population of young adults with a first‐ever ischemic stroke. Methods: Patients aged 18–54 years consecutively hospitalized in a university department of neurology for a first‐ever ischemic stroke from January 2017 to July 2021 were included. Drug use over the past year was assessed by a semistructured interview, and the stroke phenotype was described using the ASCOD classification. Results: A total of 691 patients, including 78 of 691 (11.3%) cannabis users, were included. Cannabis use was independently associated with potential A1 (odds ratio [OR] = 3.30, 95% confidence interval [CI] = 1.45–7.5, p = 0.004) and uncertain A2 (OR = 13.1, 95% CI = 2.89–59.4, p < 0.001) atherosclerotic cause of stroke after adjustment for vascular risk factors including tobacco and other drug use. Moreover, the association of atherosclerosis and cannabis use was significant for frequent (OR = 3.13, 95% CI = 1.07–8.6, p = 0.030) and daily cannabis use (OR = 4.43, 95% CI = 1.40–13.4, p = 0.008), but not for occasional use. Conclusions: We found a significant, independent, and graded association of cannabis use with the atherosclerotic stroke phenotype. [ABSTRACT FROM AUTHOR]

The article presents a case report of a patient with cardioembolic ischemic stroke (IS), which was the first clinical manifestation of congenital atrial septal defect (ASD), asymptomatic until adulthood. The issues of anatomical classification, restructuring of intracardiac hemodynamics depending on the size and localization of ASD, its role in the development of IS are discussed. The diagnostic algorithm in patients with IS caused by paradoxical embolism is described, the current possibilities of ASD treatment and prevention of related disorders of cerebral circulation are discussed.

Background: The inflammatory response plays an important role in ischemic stroke, and the incidence of stroke in young adults has increased rapidly in recent years. The C-reactive protein-to-albumin ratio (CAR) is a new index that reflects the overall inflammatory status of patients with major diseases; however, no studies have reported the relationship between CAR and young stroke. Methods: The participants' baseline characteristics and laboratory examination results, including CAR, were obtained at admission. The modified Rankin Scale (mRS) scores at the 30-day and 90-day follow-ups were obtained from all patients. All the participants included in the study were classified into four groups according to CAR quartiles (Q1-Q4). Logistic regression was used to analyze the relationship between different CAR levels and adverse outcomes (mRS 3-6 and mRS 2-6). We also plotted receiver operating characteristic curves of CAR for adverse clinical outcomes and calculated the area under the curve and cutoff values. Results: A total of 630 patients with young stroke were enrolled in the study. In the multivariate logistic regression model, at the 30-day follow-up, the Q3 and Q4 (significantly increased CAR) groups showed an elevated risk of mRS score of 2-6 (odds ratio [OR]: 2.94; 95% confidence interval [CI]: 1.40-6.16, p < 0.01; OR: 4.01; 95% CI: 1.88-8.91, p < 0.01). At the 90-day follow-up, the Q3 and Q4 groups still showed an elevated risk of an mRS score of 2-6 (Q3, OR: 2.76; 95% CI: 1.30-5.86, p < 0.01; Q4, OR: 2.63; 95% CI: 1.22-5.65, p < 0.01). Results: A total of 630 patients with young stroke were enrolled in the study. In the multivariate logistic regression model, at the 30-day follow-up, the Q3 and Q4 (significantly increased CAR) groups showed an elevated risk of mRS score of 2-6 (odds ratio [OR]: 2.94; 95% confidence interval [CI]: 1.40-6.16, p < 0.01; OR: 4.01; 95% CI: 1.88-8.91, p < 0.01). At the 90-day follow-up, the Q3 and Q4 groups still showed an elevated risk of an mRS score of 2-6 (Q3, OR: 2.76; 95% CI: 1.30-5.86, p < 0.01; Q4, OR: 2.63; 95% CI: 1.22-5.65, p < 0.01).

Introduction. Since the turn of the century, epidemiological studies have shown an increase in stroke hospitalisation rates among young adults in contrast to a decline in rates seen among the older population. The aim of the present study was to investigate the trends of stroke hospitalisation rates and case fatality ratios (CFR) over the decade starting in 2010 in different age groups of the Polish population. Material and methods. The patients were identified on the basis of the Polish National Health Fund that gathers all the data of the Hospital Discharge Registry as well as the National Cause of Death Registry of patients with stroke who were hospitalised between 2010 and 2019 and who were diagnosed according to the International Classification of Diseases — Tenth Revision (ICD-10) with haemorrhagic stroke (HS; codes I61* and I62*) and ischaemic stroke (IS; codes I63*). Results. From a total nationwide cohort of 799,132 stroke patients (86.2% with IS and 13.8% with HS) treated between 2010 and 2019, a group of 22,329 patients (2.79%) aged 18–44 years was selected, among whom 69.6% had IS and 30.4% had HS. We documented a statistically significant increase in the IS hospitalisation rate in young adults alongside a decrease of this rate in those aged > 64. Among young adults with IS, the highest increase (p = 0.001) was observed for those aged 35–44 in 2019 (up to 39.2), and was significant each year starting from 2017 (2017–2019: p < 0.01). In the case of HS, the annual number of patients did not change significantly. In 2019 (compared to 2010), a decrease in 30-day, 90-day and 1-year CFR was noted in all age groups of patients with IS and HS. Stroke aetiology of IS was diagnosed in 60% of patients. More than 40% of patients with IS were discharged with the diagnosis of stroke of unspecified cause. Conclusions. In the case of IS, opposite trends of hospitalisation rates in younger and older age groups were documented, with the highest increase of IS in patients aged 35–44. A decline in CFR was observed for both IS and HS in all age groups. [ABSTRACT FROM AUTHOR]

Background: Migraine with aura (MWA) is a risk factor for stroke, but the mechanisms underlying this association remain unclear. Our aim was to assess the association between MWA and cerebral small-vessel disease (CSVD) ischemic stroke after adjustment for vascular risk factors in a population of young patients hospitalized for a first-ever ischemic stroke., Methods: Patients aged 18-54 years consecutively hospitalized for a first-ever acute ischemic stroke at the neurovascular unit of our university hospital between January 2017 and July 2021 were included in this retrospective cohort study. CSVD lesions were assessed and classified according to ASCOD (Atherosclerosis, Small-Vessel Disease, Cardiac pathology, Others causes, Dissection) classification criteria., Results: In total, 646 patients were included (median (SD) age, 44.03 (9.01) years; 61.8% male) including 115 patients with MWA and 110 patients with migraine without aura (MWoA). Grade S1, potentially causal, CSVD lesions were significantly less frequent in patients with MWA (odds ratio (OR) = 0.35, 95% cofdence interval (CI)  =  0.13-0.95, p  = 0.048) compared to non-migraine patients in univariate analysis. Logistic regression adjusting for vascular risk factors showed no significant association of CSVD of any grade (S1, S2 or S3 vs. S0) with migraine: OR = 0.78, 95% CI = 0.48-1.28, p  = 0.34; MWoA: OR = 0.81, 95% CI = 0.42-1.47, p  = 0.51; and MWA: OR = 0.84, 95% CI = 0.43-1.56, p  = 0.60, as well as no association of grade S1 CSVD lesions with migraine: OR = 0.91, 95% CI = 0.40-1.92, p  = 0.81; MWoA: OR = 1.11, 95% CI = 0.42-2.64, p  = 0.81; and MWA: OR = 0.72, 95% CI = 0.20-1.98, p  = 0.56., Conclusions: In a retrospective study including almost 650 young adults hospitalized for a first ischemic stroke, MWA was not associated with CSVD cause of stroke after adjustment for vascular risk factors., Competing Interests: Declaration of conflicting interestsCG reports speaker fees from Novartis, Teva, Lilly, Pfizer, Abbvie, Lundbeck and Orkyn.FC, GG, FL, MM and VL declare that they have no conflicts of interest.

Stroke survivors develop late complications after stroke (LCAS) that impair return to pre-stroke responsibilities. Optimal strategies for detection have not been developed. We assessed differences in LCAS symptom detection among young stroke survivors undergoing active surveillance versus usual care. This was a retrospective cohort study including patients age 18–50 with ischemic stroke, transient ischemic attack, or intracerebral hemorrhage evaluated in a Stroke Clinic between 1/1/2016–12/31/2017 with at least one outpatient evaluation during the first year after stroke. "Active surveillance" involved a semi-structured interview to elicit LCAS symptoms including headache, seizures, lethargy, mood disorders, cognitive impairment, central pain, insomnia, spasticity, dystonia, and orthostasis. "Usual care" did not involve the interview. Rates of LCAS symptom detection were assessed at 0–3 months and 3–12 months. One hundred twenty-one stroke survivors were included, of which 37% (45) underwent active surveillance. There were no differences in baseline characteristics except hospitalization location. Patients undergoing active surveillance were more likely to have at least one LCAS symptom detected (77% vs 49% at 0–3 months, p = 0.02; 81% vs. 54% at 3–12 months, p = 0.008). Active surveillance was more likely to detect symptoms of non-motor LCAS. There were no differences for motor LCAS. Active surveillance leads to higher rates of early symptom detection of non-motor LCAS in young stroke survivors. Young stroke survivors frequently have late complications after stroke (LCAS) that impair return to pre-stroke responsibilities. Active surveillance for LCAS symptoms with a semi-structured interview increases detection of non-motor late complications. A bundled approach to screening for LCAS symptoms is pragmatic as a majority of young stroke survivors have at least one symptom but no single symptom is present in all stroke survivors.

Large vessel occlusion-acute ischemic stroke (LVO-AIS) is infrequent in young adults and exhibits distinct stroke mechanisms compared to older adults. This study sought to evaluate the impact of varying stroke etiologies on treatment-related outcomes in young adults with LVO-AIS, an aspect that remains unclear. This retrospective cohort study included patients aged 18-50 presenting with AIS from January 2017 to December 2021 within our multi-center stroke network. Patients with LVO on CTA/MRA at presentation were included. We assessed demographics, stroke etiology (TOAST classification), and treatment-related outcomes. Based on intervention received, patients were divided into 5 groups [IV-thrombolysis (IVT) only, Mechanical Thrombectomy (MT) only, IVT+MT, no treatment, unsuccessful MT]. Among 1210 AIS patients, 220 with LVO were included. The median age was 42 (36, 46). 75 (34.1 %) patients underwent successful MT (46.7 % received IVT+MT). 26 (11.8 %) received IVT only, 110 (50 %) received neither intervention, and 9 (4.1 %) underwent unsuccessful MT. Per TOAST, 17.4 % had large artery atherosclerosis (LAA), 19.2 % cardio-embolism, 28.6 % stroke of other etiology, and 34.7 % had undetermined etiology. Favorable thrombectomy outcomes (TICI 2b/2c/3) were observed in 87.2 %. Discharge NIH Stroke Scale (NIHSS) scores improved for patients with IVT+MT in all TOAST categories except LAA. Young adults with LVO-AIS had good outcomes irrespective of stroke etiology, except LAA, which was associated with a higher discharge NIHSS. Moreover, 50 % of young adults in our study received no intervention, a quarter of those owing to delayed presentation. Further studies are needed to identify barriers in seeking acute treatment in young adults with LVO-AIS. [ABSTRACT FROM AUTHOR]

Young adults with stroke have distinct professional and social roles making them vulnerable to symptoms of post-stroke depression (PSD) and post-stroke anxiety (PSA). Prior reviews have examined the prevalence of anxiety and depression in stroke populations. However, there are a lack of studies that have focused on these conditions in young adults. We performed a systematic review and meta-analysis of observational studies that reported on symptoms of PSD, PSA and comorbid PSD/PSA in young adults aged 18 to 55 years of age. MEDLINE, EMBASE, SCOPUS and PsycINFO were searched for studies reporting the prevalence of symptoms of PSD and/or PSA in young adults with stroke from inception until June 23, 2023. We included studies that evaluated depression and/or anxiety symptoms with screening tools or interviews following ischemic or hemorrhagic stroke. Validated methods were employed to evaluate risk of bias. 4748 patients from twenty eligible studies were included. Among them, 2420 were also evaluated for symptoms of PSA while 847 participants were evaluated for both PSD and PSA symptoms. Sixteen studies were included in the random effects meta-analysis for PSD symptoms, with a pooled prevalence of 31 % (95 % CI 24–38 %). Pooled PSA symptom prevalence was 39 % (95 % CI 30–48 %) and comorbid PSD with PSA symptom prevalence was 25 % (95 % CI 12–39 %). Varying definitions of 'young adult', combinations of stroke subtypes, and methods to assess PSD and PSA contributed to high heterogeneity amongst studies. We identified high heterogeneity in studies investigating the prevalence of symptoms of PSD and PSA in young adults, emphasizing the importance of standardized approaches in future research to gain insight into the outcomes and prognosis of PSD and PSA symptoms following stroke in young adults. Larger longitudinal epidemiological studies as well as studies on tailored interventions are required to address the mental health needs of this important population. None. [ABSTRACT FROM AUTHOR]

We describe a case of a 36-year-old man who presented with stroke in the right paramedian pons in the pontine perforator territory, manifesting as intermittent headache, slurred speech, left-sided weakness, and paresthesia. This case highlights the diagnostic challenge in identifying neurosyphilis as a cause of stroke in young individuals. Clinicians should maintain vigilance for this uncommon etiology through conducting a detailed history and investigation in susceptible patients with key risk factors. Once the diagnosis was confirmed in our case, a multidisciplinary approach was used for management with neurologists, infectious disease specialists, and the neurointerventional team. Our patient ultimately underwent successful therapy with mechanical thrombectomy for basilar artery thrombosis from meningovascular syphilis.

Introduction: Migraine is a risk factor for ischemic stroke, but the mechanisms of stroke associated with migraine are debated. The aim of this study was to investigate the association between migraine and large artery atherosclerosis (LAA) in young adults with ischemic stroke. Methods: Patients aged between 18 and 54 years consecutively treated for first acute ischemic stroke in a university hospital stroke unit between January 2017 and December 2019 were included in this cross‐sectional study. Migraine status was systematically assessed by the same headache specialist. Stenotic and nonstenotic LAA of extracranial and intracranial cerebral arteries were evaluated and graded using the ASCOD (atherosclerosis, small‐vessel disease, cardiac pathology, other causes, dissection) criteria. We adjusted the association between migraine and LAA for traditional risk factors. Results: A total of 415 patients were included (mean age [standard deviation], 43.9 [8.7] years; 258/415 [62.2%] men). Migraine with aura (MWA) was diagnosed in 76 patients, and migraine without aura (MWoA) in 68 patients. Patients with migraine had fewer traditional cardiovascular risk factors. Stenotic LAA (10/144 [6.9%] vs. 42/271 [15.5%]; p < 0.001) and LAA of any grade (35/144 [24.3%] vs. 138/271 [50.9%]; p < 0.001) were significantly less frequent in patients with migraine than in patients without migraine, respectively. Multivariable analysis adjusting for age, sex, overweight, tobacco use, hypertension, diabetes, and hyperlipidemia showed a negative association between migraine and LAA of any grade (odds ratio [OR] = 0.44, 95% confidence interval [CI: 0.254–0.78], p = 0.005). This negative association was found for both MWoA (OR = 0.42, 95% CI [0.204–0.88], p = 0.020) and MWA (OR = 0.47, 95% CI [0.228–0.96], p = 0.037) compared to no migraine. Conclusion: In this study of young adults with ischemic stroke, migraine had a negative association with LAA. This negative association was independent of traditional vascular risk factors and was found for both MWA and MWoA. [ABSTRACT FROM AUTHOR]

We report a case of a 53-year-old woman admitted to the emergency department with left hemiplegia, tinnitus and palpitations. A cerebral and cervical computed tomography angiography revealed an acute large ischemic stroke on the right Sylvian territory, which was related to a dissection of the right internal carotid. Moreover, a left internal carotid pseudo-aneurysm was observed.These two injuries were presumably imputable to a bilateral Eagle Syndrome.Indeed, the temporal styloid processes were measured at 31mm on both sides.To support our hypothesis of a stylocarotid impingement, a cervical CTA with hyperflexion (45°) of the neck was performed. It clearly revealed the bilateral impingement between the styloid processes and internal carotids.It seems important to know that Eagle syndrome may lead to disabling diseases or even death as well as an ischemic stroke. The vascular impingement with bilateral vascular injuries was never described.To our knowledge, our “neck flexion cervical CTA” to reveal the stylocarotid impingement has never been described before. This approach could lead to a new investigation technique, to better identify this underestimated pathology in the medical doctors community.

IntroductionMigraine with aura (MWA) has been associated with cryptogenic ischemic stroke (CIS) after adjustment for the presence of a patent foramen ovale (PFO) assessed by a transcranial Doppler. This study aimed at evaluating the association of MWA with causal PFO assessed by Transesophageal echocardiography (TEE) in CIS.MethodsPatients aged 18–54 years consecutively treated for first acute ischemic stroke in a university hospital stroke unit, between January 2017 and December 2019, were included in this cross-sectional study. Associations between migraine subtypes and PFO were tested for all PFO, possibly causal PFO (PFO with large shunt and/or atrial septal aneurysm [ASA]), and the probably causal PFO subset (large shunt and/or ASA, plus risk of paradoxical embolism [RoPE] score ≥ 7). We adjusted the association between migraine subtypes and possibly causal PFO, which included the probably causal subset for age, sex, large artery atherosclerosis, and small vessel disease.ResultsA total of two hundred and two patients with CIS were included, of whom 42/202 (20%) had MWA, 32/202 (15%) had migraine without aura, and 128/202 (63%) had no migraine. MWA was associated with possibly causal PFO (OR = 4.0, 95%CI [1.78–9.3], P < 0.001) and with probably causal PFO (OR = 5.4, 95%CI [2.37–13], P < 0.001). In a multinomial logistic regression analysis, MWA remained associated with possibly causal PFO (OR = 3.24, 95% CI [1.45–7.2], P = 0.004).ConclusionIn a young adult population with CIS, MWA was strongly associated with possibly causal PFO, i.e., with a large shunt or combined with an interatrial septal aneurysm.

Background: Incidence of cryptogenic ischemic stroke (CIS) in young adults is increasing. Early left atrial (LA) myopathy might be 1 of the underlying mechanisms, but this has only been scarcely explored., Objectives: The purpose of this study was to assess the association between increased LA stiffness and CIS in young adults., Methods: In the multicenter SECRETO (Searching for Explanations for Cryptogenic Stroke in the Young: Revealing the Etiology, Triggers, and Outcome) study, LA function was analyzed by speckle tracking echocardiography in 150 CIS patients (aged 18-49 years) and 150 age- and sex-matched controls. Minimum and maximum LA volumes, LA reservoir and contractile strain were measured. LA stiffness was calculated by the ratio: mitral peak E-wave velocity divided by mitral annular e' velocity (E/e')/LA reservoir strain and considered increased if ≥0.22. Increased LA volumes, LA stiffness, and/or reduced LA strain indicated LA myopathy. Logistic regression was used to determine the relation between LA stiffness and CIS and the clinical variables associated with LA stiffness., Results: Increased LA stiffness was found in 36% of patients and in 18% of controls ( P  < 0.001). Increased LA stiffness was associated with a 2.4-fold (95% CI: 1.1-5.3) higher risk of CIS after adjustment for age, sex, comorbidities, and echocardiographic confounders ( P  = 0.03). In patients, obesity, pre-CIS antihypertensive treatment, older age, and lower LA contractile strain were all related to increased LA stiffness (all P  < 0.05)., Conclusions: LA myopathy with increased LA stiffness and impaired LA mechanics more than doubles the risk of CIS in patients under the age of 50 years. This provides new insights into the link between LA dysfunction and CIS at young ages.

TRANSLATIONAL OUTLOOK: Patients with premature LA disease may benefit from early intervention, like antithrombotic therapy. This should be further investigated in clinical studies addressing preventive and therapeutic interventions in young patients at high risk of ischemic stroke., (© 2024 The Authors.)

Background Stroke is a serious complication of hypertensive disorders of pregnancy (HDP), with potentially severe and long‐term sequelae. However, the temporal trends, predictors, and outcomes of stroke in women with HDP at delivery remain unknown. Methods and Results All HDP delivery hospitalizations with or without stroke event (ischemic, hemorrhagic, or unspecified) between 2004 and 2014 in the United States National Inpatient Sample were analyzed to examine incidence, predictors, and prognostic impact of stroke. Of 4 240 284 HDP delivery hospitalizations, 3391 (0.08%) women had stroke. While the prevalence of HDP increased over time, incident stroke rates decreased from 10 to 6 per 10 000 HDP delivery hospitalizations between 2004 and 2014. Women with stroke were increasingly multimorbid, with some risk factors being more strongly associated with ischemic strokes, including congenital heart disease, peripheral vascular disease, dyslipidemia, and sickle cell disease. Delivery complications were also associated with stroke, including cesarean section (odds ratio [OR], 1.58; 95% CI, 1.33–1.86), postpartum hemorrhage (OR, 1.91; 95% CI, 1.33–1.86), and maternal mortality (OR, 99.78; 95% CI, 59.15–168.31), independently of potential confounders. Women with stroke had longer hospital stays (median, 6 versus 3 days), higher hospital charges (median, $14 655 versus $4762), and a higher proportion of nonroutine discharge locations (38% versus 4%). Conclusions The incidence of stroke in women with HDP has declined over time. While a relatively rare event, identification of women at highest risk of ischemic or hemorrhagic stroke on admission for delivery is important to reduce long‐term sequelae.

Long-term consequences of cervical artery dissection (CeAD), a major cause of ischemic stroke in young people, have been poorly investigated. The Italian Project on Stroke at Young Age - Cervical Artery Dissection (IPSYS CeAD) project is a multicenter, hospital-based, consecutively recruiting, observational, cohort study aimed to address clinically important questions about long-term outcome of CeAD patients, which are not covered by other large-scale registries. Patients with radiologically diagnosed CeAD were consecutively included in the registry. Baseline demographic and clinical variables, as well as information on risk factors, were systematically collected for each eligible patient. Follow-up evaluations were conducted between 3 and 6 months after the initial event (t1) and then annually (t2 at 1 year, t3 at 2 years , and so on), in order to assess outcome events (long-term recurrent CeAD, any fatal/nonfatal ischemic stroke, transient ischemic attack (TIA), or other arterial thrombotic event, and death from any cause). Between 2000 and 2019, data from 1530 patients (age at diagnosis, 47.2 ± 11.5 years; women, 660 [43.1%]) have been collected at 39 Italian neurological centers. Dissection involved a single vessel in 1308 (85.5%) cases and caused brain ischemia in 1303 (85.1%) (190 TIA/1113 ischemic stroke). Longitudinal data are available for 1414 (92.4%) patients (median follow-up time in patients who did not experience recurrent events, 36.0 months [25th to 75th percentile, 63.0]). The collaborative IPSYS CeAD effort will provide novel information on the long-term outcome of CeAD patients. This could allow for tailored treatment approaches based on patients' individual characteristics. [ABSTRACT FROM AUTHOR]

Fabry disease (FD) is a treatable X-linked lysosomal storage disorder caused by GLA gene variants leading to alpha-galactosidase A deficiency. FD is a rare cause of stroke, and it is still controversial whether in stroke patients FD should be searched from the beginning or at the end of the diagnostic workup (in cryptogenic strokes). Fabry-Stroke Italian Registry is a prospective, multicentric screening involving 33 stroke units. FD was sought by measuring α-galactosidase A activity (males) and by genetic tests (males with reduced enzyme activity and females) in patients aged 18–60 years hospitalized for TIA, ischemic stroke, or intracerebral hemorrhage. We diagnosed FD in patients with 1) already known pathogenic GLA variants; 2) novel GLA variants if additional clinical, laboratory, or family-derived criteria were present. Out of 1906 patients, we found a GLA variant in 15 (0.79%; 95%CI 0.44–1.29) with a certain FD diagnosis in 3 (0.16%; 95%CI 0.03–0.46) patients, none of whom had hemorrhage. We identified 1 novel pathogenic GLA variant. Ischemic stroke etiologies in carriers of GLA variants were: cardioaortic embolism (33%), small artery occlusion (27%), other causes (20%), and undetermined (20%). Mild severity, recurrence, previous TIA, acroparesthesias, hearing loss, and small artery occlusion were predictors of GLA variant. In this large multicenter cohort the frequency of FD and GLA variants was consistent with previous reports. Limiting the screening for GLA variants to patients with cryptogenic stroke may miss up to 80% of diagnoses. Some easily recognizable clinical features could help select patients for FD screening. [Display omitted] • GLA variants are identified in 0.9% of Italian adults with TIA/ischemic strokes. • Screening for Fabry disease should be widened to all stroke pathogenesis. • Mild recurrent strokes and small vessel occlusion may hide a GLA variant. • Acroparesthesias and hearing loss in a stroke patient should suggest GLA variants.

Background and purpose: Neurofilament light chain (NfL) is a marker of neuroaxonal damage. We aimed to study associations between serum NfL (sNfL) concentrations at different time points after ischemic stroke and outcomes. Methods: We prospectively included ischemic stroke cases (n = 595, mean age 59 years, 64% males) and assessed outcomes by both the modified Rankin Scale (mRS) and the NIH stroke scale (NIHSS) at 3 months and by mRS at 2 years. In a subsample, long-term (7-year) outcomes were also assessed by both mRS and NIHSS. We used the ultrasensitive single-molecule array assay to measure sNfL in the acute phase (range 1–14, median 4 days), after 3 months and 7 years in cases and once in controls (n = 595). Results: Acute-phase sNfL increased by the time to blood-draw and highest concentrations were observed at 3 months post-stroke. High sNfL associated to stroke severity and poor outcomes, and both associations were strongest for 3-month sNfL. After adjusting for age, previous stroke, stroke severity, and day of blood draw, 3-month sNfL was significantly associated to both outcomes at all time points (p < 0.01 throughout). For all main etiological subtypes, both acute phase and 3-month sNfL were significantly higher than in controls, but the dynamics of sNfL differed by stroke subtype. Conclusions: The results from this study inform on sNfL in ischemic stroke and subtypes over time, and show that sNfL predicts short- and long-term neurological and functional outcomes. Our findings suggest a potential utility of sNfL in ischemic stroke outcome prediction. [ABSTRACT FROM AUTHOR]

Objective: Whether migraine modifies after spontaneous cervical artery dissection (sCeAD) more than after other stroke etiologic subtypes has never been adequately investigated.Methods: In the setting of the Italian Project on Stroke in Young Adults (IPSYS), we compared the course of migraine before and after acute brain infarct in a group of migraine patients with sCeAD and a group of migraine patients whose ischemia was due to a cause other than CeAD (non-CeAD IS), matched by sex, age (± 3 years), and migraine subtype.We applied linear mixed models to evaluate pre-event vs post-event changes and differences between sCeAD and non-CeAD IS patients.Results: Eighty-seven patients per group (migraine without aura/migraine with aura, 67/20) qualified for the analysis. After the acute event, migraine headaches disappeared in 14.0% of CeAD patients vs 0.0% of non-CeAD IS patients (p ≤ 0.001). Migraine frequency (patients suffering at least 1 attack, from 93.1 to 80.5%, p = 0.001), pain intensity (from 6.7 ± 1.7 to 4.6 ± 2.6 in a 0 to 10 pain scale, p ≤ 0.001), and use of acute anti-migraine medications (patients taking at least 1 preparation, from 81.6 to 64.4%, p = 0.007) also improved significantly after CeAD as opposed to that observed after non-CeAD IS.Conclusion: The spontaneous improvement of migraine after sCeAD reinforces the hypothesis of a pathogenic link between the two conditions.

Herpes simplex virus 2 (HSV-2) is a very rare cause of central nervous system (CNS) infections. We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-2 DNA was identified by PCR, with a positive viral load in favor of active replication. No other viral or microbiological infections were identified. MRI angiography confirmed a vasculitic process involving the left carotid artery, and a HSV-2 vasculitis diagnosis was assumed. The patient started acyclovir with improvement of clinical features and imaging abnormalities. In the HIV-infected patient, stroke is a multifactorial common cause of morbidity. The physician should take into account a broad differential diagnosis including rare causes and atypical presentations of common etiologies, including HSV-1 and HSV-2 CNS infection.

Background: The role of nonobstructive (<50% stenosis) carotid atherosclerosis (NOCA) in young adults with ischemic stroke is not well understood. In the present study, we investigated the prevalence and the ultrasonic characteristics of NOCA in a consecutive series of young adults with cryptogenic stroke (CS).Methods: Patients aged 18-54, consecutively treated in a tertiary hospital for first-ever CS (defined as an ischemic stroke without ASCOD (A: atherosclerosis; S: small-vessel disease; C: cardiac pathology; O: other causes) grade 1 potential cause) in the carotid artery territory, were prospectively enrolled. NOCA was assessed using carotid duplex ultrasonography.Results: Of 148 patients with first-ever ischemic stroke, 70 had CS, including 44 patients with carotid CS. NOCA was found in 22 of 44 (50%) patients. All but 1 plaque were echolucent. NOCA was bilateral in 15 patients and unilateral in 7 patients. All unilateral plaques were on the symptomatic side (P = .02). Plaque thickness, plaque length, and plaque volume were greater on the symptomatic side than on the asymptomatic side (P = .001, P < .001, and P < .001, respectively). Discrimination between the symptomatic and the asymptomatic side using any of these plaque metrics was good with areas under the curve (95% confidence interval) of .82 (.69-0.95), .85 (.74-0.96), and .87 (.75-0.99) for plaque thickness, plaque length, and plaque volume, respectively.Conclusions: NOCA is frequent in young adults with CS. Measurement of the plaque burden with carotid duplex may help to identify symptomatic NOCA. [ABSTRACT FROM AUTHOR]

Background and Purpose: Ovarian hyperstimulation syndrome (OHSS) is a serious complication that occurs after the ovarian-induction treatment. Acute cerebrovascular accident is one of the most dangerous manifestations of the syndrome. However, the characteristics of stroke resulting from OHSS have so far not been well summarised in any study. Methods: We reported 2 cases of acute cerebrovascular accidents secondary to OHSS. And then we performed a literature search for reports on this type of stroke, and summarised their characteristics. Results: Thirty-six published cases of this type of stroke were reviewed. Thirty two out of 36 (88.9%) of the women were 35 years old or younger. Stroke in 28 out of 36 (77.8%) of these cases was caused by arterial thrombosis. In 17 out of 28 cases, the involved cerebral vascular branches were mainly middle cerebral artery (MCA) and internal carotid artery (ICA). The acute cerebrovascular accidents happened 7 and 9.25 days after embryo transplantation or 8 and 8.33 days after last human chorionic gonadotropin treatment respectively. The prognosis of patients was relatively good after anticoagulation and some supportive treatments. Conclusion: The MCA and ICA are easily involved in stroke resulting from OHSS. The young age may be a risk factor for developing stroke secondary to OHSS. Once thromboembolism develops, administering appropriate therapy is crucial. [ABSTRACT FROM AUTHOR]

A noticeable increase of up to 40% in the incidence of stroke among young population over the past decade has been noted. This study aimed to investigate the incidence, risk factors, and outcomes of stroke and its subtypes in young adults compared to older population. A retrospective study of patients which included patients with confirmed diagnosis of stroke based on the International Classification of Diseases 10th Revision (ICD-10) classification between the years 2018 and 2020 was conducted. The results indicated that patients less than 45 years of age had a higher incidence of hemorrhagic stroke as compared to the other age groups (p=0.011). Hypertension leading to hemorrhagic stroke was higher in patients less than 45 years of age as compared to other groups (18 years {19.4%} versus 33 years {7.5%}, p=0.001). Hypertension was noted to be the leading risk factor for stroke among the younger population., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Moosa et al.)

BackgroundStudies have reported increasing incidence of ischemic stroke in adults younger than 50 to 55 years. Information on temporal trends of other stroke subtypes and transient ischemic attack (TIA) is sparse. The aim of this study was to investigate temporal trends of the incidence of hospitalizations for TIA and stroke including sex‐ and subtype‐specific trends in young adults aged 15 to 30 years. Methods and ResultsFrom the Danish National Patient Register, we identified all cases of first‐ever stroke and TIA (age 15–30 years) in Denmark, who were hospitalized during the study period of 1994 to 2012. Incidence rates and estimated annual percentage changes (EAPCs) were estimated by using Poisson regression. During the study period, 4156 cases of first‐ever hospitalization for stroke/TIA were identified. The age‐standardized incidence rates of hospitalizations for stroke increased significantly (EAPC 1.83% [95% CI 1.11–2.55%]) from 11.97/100 000 person‐years (PY) in 1994 to 16.77/100 000 PY in 2012. TIA hospitalizations increased from 1.93/100 000 PY in 1994 to 5.81/100 000 PY in 2012 and after 2006 more markedly in men than in women (EAPC 16.61% [95% CI 10.45–23.12%]). The incidence of hospitalizations for ischemic stroke was markedly lower among men, but increased significantly from 2006 (EAPC 14.60% [95% CI 6.22–23.63%]). The incidences of hospitalizations for intracerebral hemorrhage and subarachnoid hemorrhage remained stable during the study period. ConclusionsThe incidence rates of first‐time hospitalizations for ischemic stroke and TIA in young Danish adults have increased substantially since the mid 1990s. The increase was particularly prominent in the most recent years.

Introduction: We aimed to investigate the prevalence of cognitive impairment in the subacute phase after transient ischemic attack (TIA) and ischemic stroke (IS), factors associated with a vascular cognitive disorder, and the prevalence of subjective cognitive complaints and their relation with objective cognitive performance., Patients and Methods: In this multicenter prospective cohort study, we recruited patients with first-ever TIA and IS, aged 18-49 years, between 2013 and 2021 for cognitive assessment up to 6 months after index event. We calculated composite Z-scores for seven cognitive domains. We defined cognitive impairment as a composite Z-score < -1.5. We defined major vascular cognitive disorder as a Z-score < -2.0 in one or more cognitive domains., Results: Fifty three TIA and 545 IS patients completed cognitive assessment with mean time to assessment of 89.7 (SD 40.7) days. The median NIHSS at admission was 3 (interquartile range, 1-5). Cognitive impairment was common in five domains (up to 37%), with similar proportion in TIA and IS patients. Patients with major vascular cognitive disorder had a lower education level, higher NIHSS scores and more frequent lesions in the left frontotemporal lobe than without vascular cognitive disorder ( p  < 0.05 FDR-corrected). Subjective memory and executive cognitive complaints were present in about two-thirds of the patients, but were weakly associated with objective cognitive performance (β: -0.32 and -0.21, respectively)., Discussion and Conclusion: In the subacute phase after TIA or stroke in young adults, cognitive impairment and subjective cognitive complaints are prevalent, but they are weakly associated with each other., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: AT is a junior staff member of the Dutch Heart Foundation (grant number 2016T044).

Background and purpose Few studies exist on long-term post-stroke depressive symptoms and anxiety in young adults, although these young patients have a particular interest in their long-term prognosis, given their usually long life expectancy and being in the midst of an active social, working and family life. The aims of this study were to investigate the prevalence of depressive symptoms and anxiety and their association with clinical and demographic variables and with functional outcome after stroke in young adults. Methods and results Long-term prevalence of depressive symptoms and anxiety was calculated in 511 patients with a transient ischaemic attack or ischaemic stroke, aged 18-50 years, using the Hospital Anxiety and Depression scale, compared with 147 controls. Functional outcome was assessed with the modified Rankin Score ( mRS) and the Instrumental Activities of Daily Living scale ( IADL). 16.8% of patients had depressive symptoms and 23.0% had anxiety, versus 6.1% ( P = 0.001) and 12.2% ( P < 0.001) in controls. In ischaemic stroke patients, depressive symptoms and anxiety were associated with poor functional outcome ( mRS > 2 or IADL < 8). Conclusion Even a decade after stroke at young age, depressive symptoms and anxiety were prevalent and associated with poor functional outcome. Therefore, even in the long term, treating physicians should be aware of the long-term presence of these symptoms as their recognition may be the first step in improving long-term functional independence.

To analyze the association of stroke etiological subtypes with severity and outcomes at 3 and 12 months in patients ≤50 years. Observational study of patients admitted to a stroke unit (2007-2013). Variables: demographic data, vascular risk factors, comorbidities, severity on admission (NIHSS), and good functional outcome (mRS ≤ 1) at 3 and 12 months. We used multivariate analyses to evaluate the influence of stroke etiology on severity and outcomes. We included 214 patients, 58.3 % men, mean age 41.4 years. General linear models showed all etiologies were more severe than lacunar strokes (P < 0.05). Atherothrombotic strokes showed greater severity than those of undetermined and uncommon etiology, whereas cardioembolic strokes were more severe than cryptogenic. Taking into account specific etiologies, atherothrombotic strokes ( B = 5.860; 95 % CI 2.979-8.751), cervical artery dissection (CAD) [ B = 7.485; 95 % confidence interval (CI) 4.734-10.237], and atrial fibrillation (AF) strokes ( B = 5.773; 95 % CI 2.704-8.132) were more severe than other etiologies. Logistic regression models showed that strokes of uncommon etiology, especially those not related to CAD, had a lower probability of good outcome at 3 months [odds ratio (OR) = 0.197; CI 95 % 0.044-0.873], whereas atherothrombotic strokes were associated with this probability at 12 months (OR = 0.187; 95 % CI 0.037-0.951; P = 0.007). In patients ≤50 years of age, strokes of atherothrombotic, cardioembolic (particularly those due to AF), and uncommon etiology had a greater severity than the rest. Furthermore, strokes of uncommon etiology, especially those different from CAD, decreased the probability of a good outcome at 3 months, as did atherothrombotic strokes at 1 year.

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 nontraditional 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/1.73m 2 . 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. [ABSTRACT FROM AUTHOR]

Due to their young age young stroke survivors have to cope with a dramatic impact on their life for the decades to come. We investigated the sex-specific very long-term functional outcome after transient ischemic attack (TIA) and ischemic stroke (IS) in adults aged 18-50 years. This study is part of a cohort study among 619 first-ever young ischemic stroke patients, admitted to our department between January 1, 1980 and November 1, 2010. Functional outcome was assessed during follow-up in 2009-2011 and in 2014-2015 with the modified Rankin Scale (mRS) and instrumental Activities of Daily Living scale (iADL). Risk factors for a poor functional outcome (mRS > 2 and iADL < 8) were calculated by logistic regression analysis. After a mean follow-up of 13.9 (SD 8.2) years, 24.5 % of TIA patients and 44.7 % of IS patients had a poor functional outcome (mRS > 2). When assessing the survivors, 15.2 % of TIA patients and 22.9 % of IS patients had a poor outcome as assessed by iADL. The strongest baseline predictors of poor outcome were female sex (OR 2.7, 95 % CI 1.5-5.0) and baseline NIHSS (OR 1.1, 95 % CI 1.1-1.2 per point increase). In conclusion, 14 years after an ischemic cerebrovascular event in young adults, one out of five IS survivors and one out of ten TIA survivors is still dependent in daily life, with a two to threefold higher risk of a poor outcome in women. This includes a period of life, during which important decisions regarding work and family life have to be made. [ABSTRACT FROM AUTHOR]

Background and purpose: The known monogenic forms of stroke are rare. The aim of this study was to analyze pedigrees of young stroke patients regarding possible monogenic cerebrovascular disease and to evaluate the possibility of genetic stroke in these families. This may contribute to a better understanding of disease mechanism in stroke. Methods: Lund Stroke Register includes consecutive patients with first-ever stroke from a defined geographical area in southern Sweden. Early-onset (≤55 years) stroke patients were systematically screened with regard to family history (FHx), and families with stroke aggregation were compiled. Participants provided information in a questionnaire on occurrence of stroke or transient ischaemic attack (TIA) in their families. Information on cardiovascular risk factors (VRFs) and clinical stroke subtype was collected. FHx for stroke was considered positive when the patient reported either ≥1 first-degree relative with stroke/TIA, or no first-degree relative but ≥3 second- or third-degree relatives with stroke/TIA in a distribution compatible with monogenic inheritance. Results: Of 4103 stroke patients registered, 426 (10%) had first-ever stroke at ≤55 years and 338 (79%) of these answered the questionnaire. Of them, 159 (47%) reported a positive FHx. Twenty-eight (18%) of the probands with positive FHx had no known VRFs. Thirty-two families with ≥4 members with stroke were identified. In all these larger families the affected individuals with stroke were present in more than one generation. Conclusion: Aggregation of stroke in families of early-onset stroke patients is not uncommon. Genetic factors with impact on stroke risk, including monogenic causes, need to be evaluated in future stroke studies. [ABSTRACT FROM AUTHOR]

Ischaemic stroke (IS) in young adults has been increasingly recognized as a serious health condition. Stroke aetiology is different in young adults than in the older population. This study aimed to investigate aetiology and risk factors, and to search for predictors of outcome and recurrence in young IS patients. We conducted a prospective multicentre study of consecutive IS patients aged 16-55 years. Baseline demographic data, risk factors, stroke aetiology including systematic genetic screening for Fabry disease and severity were assessed and related to functional neurological outcome (modified Rankin Scale, mRS), case fatality, employment status, place of residence, and recurrent cerebrovascular events at 3 months. In 624 IS patients (60 % men), median age was 46 (IQR 39-51) years and median NIHSS on admission 3 (IQR 1-8). Modifiable vascular risk factors were found in 73 %. Stroke aetiology was mostly cardioembolism (32 %) and of other defined origin (24 %), including cervicocerebral artery dissection (17 %). Fabry disease was diagnosed in 2 patients (0.3 %). Aetiology remained unknown in 20 %. Outcome at 3 months was favourable (mRS 0-1) in 61 % and fatal in 2.9 %. Stroke severity ( p < 0.001) and diabetes mellitus ( p = 0.023) predicted unfavourable outcome. Stroke recurrence rate at 3 months was 2.7 %. Previous stroke or TIA predicted recurrent cerebrovascular events ( p = 0.012). In conclusion, most young adults with IS had modifiable vascular risk factors, emphasizing the importance of prevention strategies. Outcome was unfavourable in more than a third of patients and was associated with initial stroke severity and diabetes mellitus. Previous cerebrovascular events predicted recurrent ones.

Background and Purpose Post-stroke depression ( PSD) is an important complication of stroke. We studied long-term PSD after intracerebral hemorrhage ( ICH) at young age, as well as anxiety, and cognitive functioning of the survivors. Methods We gathered clinical and imaging data of 336 young ICH patients between age 16 and 49 treated in the Helsinki University Central Hospital. After a median follow-up of 9.7 (7.0-12.0) years, we interviewed 130 survivors with structural questionnaires including Beck Depression Inventory II ( BDI- II), Hospital Anxiety and Depression Scale ( HADS), Pain Anxiety Symptoms Scale ( PASS), Brief Pain Inventory ( BPI), and Montreal Cognitive Assessment (Mo CA). Univariate and multivariate analysis was performed to identify factors associated with PSD ( BDI- II score >13). Degree of disability was measured by modified Rankin Scale score ( mRS). Results PSD was present among 30 (23.1%) and anxiety among 52 (40.0%) patients ( HADS score >6). Higher degree of disability was associated with symptoms of depression (higher BDI- II scores, P = 0.001), emotional distress (higher HADS scores, P = 0.004), and pain (higher PASS scores, P = 0.008, and higher BPI scores, P = 0.003). The only baseline factor identified to associate with PSD was hydrocephalus ( P = 0.014). Median PASS score was 9 ( IQR 0-25), median BPI score was 5 (0-23), and median Mo CA score was 26 (22-28) hinting to normal or mild cognitive dysfunction. Antidepressants were used by 9.2%. Conclusions One of four survivors of ICH at young age suffers long-term PSD. Higher degree of disability predicted occurrence of PSD. Treatment of depression appears as an unmet need in young ICH survivors. [ABSTRACT FROM AUTHOR]

Background and purpose Intracerebral hemorrhage (ICH) is a devastating disorder associated with dismal outcomes. The long-term mortality and functional outcome of ICH in young patients was studied - areas so far poorly investigated. Methods A follow-up study was performed on a cohort of patients. Clinical and imaging data on ICH patients aged 16-49 were retrospectively obtained and linked with a nationwide cause-of-death register. The modified Rankin Scale (mRS) was evaluated for 30-day survivors at a visit 9.7 (7.0-12.0) years after ICH onset. Independent factors associated with mortality and unfavorable functional outcome (mRS 2-5) were sought by multivariate analysis. Results Amongst the 268 1-month survivors, 1-year survival was 98.1% [95% confidence interval (CI) 96.2%-100%], 5-year survival 93.2% (89.3%-97.1%) and 10-year survival 88.8% (84.9%-92.7%). After adjustment for age and intraventricular hematoma extension, male sex [odds ratio (OR) 3.36, 95% CI 1.28-8.80] and diabetes (OR 2.64, 1.01-6.89) were associated with increased mortality. Unfavorable functional outcome emerged in 49%. After adjustment for confounders, age (OR 1.09 per 1 year, 95% CI 1.03-1.15), initial stroke severity (1.17 per one National Institutes of Health Stroke Scale score point, 1.08-1.27) and intraventricular hemorrhage (3.26, 1.11-9.55) were associated with unfavorable functional outcome. Conclusions Of every 10 survivors of acute phase ICH at a young age, one died within 10 years after onset, male sex and diabetes being associated with increased mortality. Half the survivors did not achieve a favorable functional outcome, which was predicted by increasing age, initial stroke severity and intraventricular hemorrhage. [ABSTRACT FROM AUTHOR]

Background Limited data exist on the associated factors and correlation of leucocyte count to outcome in young adults with first-ever ischaemic stroke. Aims Our objectives were to investigate factors associated with elevated leucocyte count and whether there is correlation between leucocyte count and short- and long-term outcomes. Methods Of our database of 1008 consecutive patients aged 15 to 49, we included those with leucocyte count measured within the first two days from stroke onset. Outcomes were three-month and long-term disability, death, and vascular events. Linear regression was used to explore baseline variables associated with leucocyte count. Logistic regression and Cox proportional models studied the association between leucocyte count and clinical outcomes. Results In our study cohort of 781 patients (61·7% males; mean age 41·4 years), mean leucocyte count was high: 8·8 ± 3·1 × 109 cells/ L (Reference range: 3·4-8·2 × 109 cells/ L). Higher leucocyte levels were associated with dyslipidaemia, smoking, peripheral arterial disease, stroke severity, and lesion size. After adjustment for age, gender, relevant risk factors, both continuous leucocyte count and the highest quartile of leucocyte count were independently associated with unfavourable three-month outcome. Regarding events in the long-term (follow-up 8·1 ± 4·2 years in survivors), no association between leucocyte count and the event risks appeared. Conclusions Among young stroke patients, high leucocyte count was a common finding. It was associated with vascular disease and its risk factors as well as severity of stroke, but it was also independently associated with unfavourable three-month outcome in these patients. There was no association with the long-term outcome.

Background and purpose Intracerebral hemorrhage ( ICH) is a common and severe form of stroke but is scarcely studied in young adults. Our aim was to study risk factors, clinical presentation and early mortality of ICH in the young and compare these features with older patients. Methods All consecutive patients aged between 16 and 49 diagnosed with a first-ever ICH at the Departments of Neurology or Neurosurgery of the Helsinki University Central Hospital between January 2000 and March 2010 ( n = 336) were analyzed retrospectively. Comparisons were performed amongst demographic subgroups and with patients over 49 years of age enrolled between January 2005 and March 2010 ( n = 921). Results In the young patients, median age was 42 years (interquartile range 34-47), 59.5% were male, and annual incidence was 4.9 (95% confidence interval 4.5-5.3) per 100 000. The most prevalent risk factors were hypertension (29.8%) and smoking (22.3%). Compared with older patients hypertensive microangiopathy was less common (25.0% vs. 34.3%, P = 0.002) and structural lesions more common (25.0% vs. 4.9%, P < 0.001) assumed etiologies of ICH. The cause remained elusive in 32.1% of all young patients and in 22.5% of those who underwent magnetic resonance imaging and any angiography ( n = 89, P = 0.023). Three-month mortality rate was lower in young patients compared with older ones (17.0% vs. 32.7%, P < 0.001). Hematoma volumes were similar across all ages ( P = 0.324) and independently predicted mortality in older patients but not in the young. Conclusions Intracerebral hemorrhage ( ICH) in the young appears less fatal and has a different spectrum of causes and factors associated with short-term mortality than for the elderly.
