Histopathological Examination of a Symptomatic Carotid Web: A Case Report

Carotid webs cause ischemic stroke in young people and are associated with a high rate of stroke recurrence. Histopathological examination is crucial for clarifying the pathogenesis and mechanisms underlying the occurrence of carotid webs, although the mechanisms generally remain unclear. Here, we report a case of a symptomatic carotid web in a woman in her 50s who had a medical history of two ischemic strokes. She was diagnosed with a right carotid web and underwent carotid endarterectomy 18 days after the second stroke. Histopathological examination clearly revealed several phases of intimal hyperplasia. Furthermore, a thrombus attached to the carotid web showed invasion by fibroblasts and capillaries, and organization had begun. We presume that after the appearance of the carotid web, the thrombus formed by stagnant flow and became organized, causing the carotid web to grow and change in shape.

Mechanical thrombectomy in young patients with large vessel occlusion-related ischemic stroke: Data from the Italian Registry of Endovascular Treatment in Acute Stroke

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.

Young stroke patient with patent foramen ovale and intracranial stenosis-a case report

The prevalence of patent foramen ovale is approximately 20% in the global population. In patients under the age of 55 years, it has been proven as a cause of acute ischemic embolic stroke of otherwise undetermined source. We present a case of a 25-year-old patient who experienced an acute stroke of dominant hemisphere due to internal carotid artery occlusion.The patient underwent mechanical thrombectomy, followed by acute intracranial stenting due to persistent subocclusion of internal carotid artery. Further diagnostic investigations revealed a significant patent foramen ovale. During subsequent follow-up periods, the patient encountered multiple transient ischemic attacks despite receiving antithrombotic therapy. The indicated angiography examination revealed in-stent stenosis and thrombosis, which were resolved after optimal medical treatment. Following patent foramen ovale closure, the patient remained free from further neurological events during the subsequent two-year follow-up periods. This case emphasizes the necessity of comprehensive diagnostic evaluations in young individuals with stroke and underscores the importance of prudent slection of medical therapies.

Risk Factors, Incidence, and Outcome of Stroke: A Retrospective Cross-Sectional Hospital-Based Study Comparing Young Adults and Elderly

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.

Stroke phenotype in cannabis users among young adults with ischemic stroke

INTRODUCTION

Incidence of ischemic stroke in young adults has been steadily increasing over the last 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 non-users among a population of young adults with a first-ever ischemic stroke.

METHODS

Patients aged 18 to 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 semi-structured interview and the stroke phenotype was described using the ASCOD classification.

RESULTS

A total of 691 patients, including 78/691 (11.3%) cannabis users were included. Cannabis use was independentely associated with potential A1 (OR = 3.30, 95% 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, IC 95% [1.07-8.6], p = 0.030), and daily cannabis use (OR = 4.43, IC 95% [1.40-13.4], p = 0.008), but not for occasional use.

CONCLUSION

We found a significant, independent and graded association of cannabis use with the atherosclerotic stroke phenotype.

Association between the C-reactive protein to albumin ratio and adverse clinical prognosis in patients with young stroke

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).

CONCLUSION

A significantly increased CAR was independently associated with an increased risk of adverse outcomes in young patients with stroke.

Trends of stroke hospitalisation and fatality rates in young vs. elderly people in Poland during 2010-2019 decade

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.

Depression and Anxiety after Stroke in Young Adult Filipinos

BACKGROUND AND OBJECTIVES

Young adult patients may suffer from poststroke depression (PSD) and anxiety. Few studies have evaluated these important psychiatric conditions that may lead to adverse outcomes in young adults. We aimed to determine the prevalence of PSD and anxiety as well as to identify their predictors in a population of young Filipino adults (18-49 years old).

METHODS

We performed a cross-sectional epidemiologic study in the largest tertiary hospital in the Philippines. The study involved the administration of a structured survey tool and review of medical records. The Hospital Anxiety and Depression Score - Pilipino version (HADS-P) was used to screen for anxiety and depression. Multivariable logistic regression analysis was performed to determine significant socio-economic and clinical risk factors of PSD and anxiety.

RESULTS

114 young adult stroke patients were included. The prevalence of depression was 20.2% while that of anxiety was 34.2%. Significant predictors of PSD were the presence of anxiety (OR 1.84; CI 1.05-3.22), lower mRS scores (mRS 3-5 OR 5.52; 95% CI 1.09-8.03) and diabetes (OR 2.09; 95% CI 1.67-6.26). Meanwhile, significant predictors of poststroke anxiety included depression (OR 7.5; 95% CI 5.02-21.94) and dependency (Barthel Index scores 95-100; OR 0.94; 95% CI 0.89-0.99). Relationship status, educational attainment, stroke subtype and location were not found to be significant predictors of PSD and anxiety.

CONCLUSION

A significant proportion of young adults suffered from depression and anxiety after stroke. Clinicians should be aware of these psychiatric conditions that influence outcomes and quality of life of young adults with stroke.

Neurosyphilis presenting with a large vessel occlusion: A case report

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.

Ischemic Stroke in a Young Man: Unraveling the Domain of Myeloproliferative Disorders

Ischemic stroke is a rare phenomenon in young adults. A complete workup for hypercoagulable and myeloproliferative disorders is a cornerstone of evaluation. Essential thrombocytosis is a chronic myeloproliferative disorder that primarily involves platelets. It may remain undiagnosed in patients and subsequently present in the form of ischemic stroke. The management of this disorder is complex and often involves cytoreduction therapies. The initiation of these drugs in such patients may lead to unnecessary adverse effects and complications. This case report is an attempt to highlight an underappreciated cause of stroke when assessing young individuals.

Detection of symptoms of late complications after stroke in young survivors with active surveillance versus usual care

PURPOSE

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

Active surveillance leads to higher rates of early symptom detection of non-motor LCAS in young stroke survivors.Implications for rehabilitationYoung 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.

Temporal Trends in Pregnancy-Associated Stroke and Its Outcomes Among Women With Hypertensive Disorders of Pregnancy

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.

Misdiagnosis of acute ischemic stroke in young patients

Misdiagnosis is a challenging risk in young patients with ischemic stroke that leads to delayed recognition, prevents thrombolytic therapy and increases morbidity and mortality. To assess the frequency and reasons for misdiagnosis of ischemic stroke in young adults in the emergency department, we retrospectively evaluated 101 consecutive patients. The diagnosis required both the presence of an ischemic lesion in diffusion-weighted MRI as well as neurological symptoms. Twenty-three individuals were misdiagnosed (15 females, mean age 43 years [range 26-55 years]). The most common diagnostic errors included headache/neck pain n = 11 (48%) and peripheral vertigo n = 4 (17.3%), and the most common missed etiology was arterial dissection (AD) n = 15 (65.2%). The initial diagnosis was made by emergency physicians in 22 persons. The group with misdiagnosis had a significantly higher frequency of AD at 15 vs. 8 (p < 0.01), posterior territory involvement at 12 vs. 6 (p < 0.01), and female predominance. Misdiagnosis occurred in a third of young patients with an ischemic stroke and was more frequent in those with arterial dissection involving the posterior circulation and presenting with non-specific symptoms.

Occupational Physical Activity in Young Adults and Stroke: Was It Due to My Job?

The association of physical activity and stroke among working young adults and vice versa has increasingly empathized in recent years. Lack of physical activity, along with many other modifiable risk factors, such as hypertension, obesity, atherosclerosis, and diabetes, contributes through vascular dysfunction to the development of adverse cerebrovascular events in the future and has always been a topic of interest in the fields of neurology and stroke rehabilitation. We wrote this review article to elaborate on this relationship in detail. This article suggests that the physical activity role in stroke development and the rehabilitation process has a diverse role, where individuals with low physically active occupations are prone to develop a stroke more readily in comparison with other workers who have a moderate amount of physical activity in their jobs; however, less mobility appeared to be harmful too soon after stroke. In addition, we elucidate the effects of physical activity on sympathetic activity and remodeling of vascular response. Alterations in the neuroendocrine system include several factors. This includes harmful changes caused by increasing levels of epinephrine and norepinephrine. These changes are seen with stress-induced cerebrovascular injury and are often elevated in post-stroke patients. In contrast, post-stroke patients engaged in physical activity may prevent these harmful neurotrophic factors by reducing the elevated levels of epinephrine and norepinephrine. However, we need more studies in the near future to further explore this association process. Therefore, we recommend more research to explore the relationship of occupation-related factors and adverse stroke outcomes.

Increasing Incidence of Hospitalization for Stroke and Transient Ischemic Attack in Young Adults: A Registry-Based Study

Background

Studies 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 Results

From 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.

Conclusions

The 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.

Long-term depressive symptoms and anxiety after transient ischaemic attack or ischaemic stroke in young adults

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.

Familial aggregation of stroke amongst young patients in Lund Stroke Register

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.

Depression, anxiety, and cognitive functioning after intracerebral hemorrhage

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 (MoCA). 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 MoCA 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.

Intracerebral hemorrhage at young age: long-term prognosis

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.

Incidence, risk factors, etiology, severity and short-term outcome of non-traumatic intracerebral hemorrhage in young adults

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.

Synthetic cannabis and acute ischemic stroke

An association between marijuana use and stroke has been previously reported. However, the health risks of newer synthetic cannabinoid compounds are less well known. We describe 2 cases that introduce a previously unreported association between synthetic cannabis use and ischemic stroke in young adults. A 22-year-old woman presented with dysarthria, left hemiplegia, and left hemianesthesia within hours of first use of synthetic cannabis. She was healthy and without identified stroke risk factors other than oral contraceptive use and a patent foramen ovale without venous thromboses. A 26-year-old woman presented with nonfluent aphasia, left facial droop, and left hemianesthesia approximately 12 hours after first use of synthetic cannabis. Her other stroke risk factors included migraine with aura, oral contraceptive use, smoking, and a family history of superficial thrombophlebitis. Both women were found to have acute, large-territory infarctions of the right middle cerebral artery. Our 2 cases had risk factors for ischemic stroke but were otherwise young and healthy and the onset of their deficits occurred within hours after first-time exposure to synthetic cannabis. Synthetic cannabis use is an important consideration in the investigation of stroke in young adults.

Etiology of first-ever ischaemic stroke in European young adults: the 15 cities young stroke study

BACKGROUND AND PURPOSE

Risk factors for IS in young adults differ between genders and evolve with age, but data on the age- and gender-specific differences by stroke etiology are scare. These features were compared based on individual patient data from 15 European stroke centers.

METHODS

Stroke etiology was reported in detail for 3331 patients aged 15-49 years with first-ever IS according to Trial of Org in Acute Stroke Treatment (TOAST) criteria: large-artery atherosclerosis (LAA), cardioembolism (CE), small-vessel occlusion (SVO), other determined etiology, or undetermined etiology. CE was categorized into low- and high-risk sources. Other determined group was divided into dissection and other non-dissection causes. Comparisons were done using logistic regression, adjusting for age, gender, and center heterogeneity.

RESULTS

Etiology remained undetermined in 39.6%. Other determined etiology was found in 21.6%, CE in 17.3%, SVO in 12.2%, and LAA in 9.3%. Other determined etiology was more common in females and younger patients, with cervical artery dissection being the single most common etiology (12.8%). CE was more common in younger patients. Within CE, the most frequent high-risk sources were atrial fibrillation/flutter (15.1%) and cardiomyopathy (11.5%). LAA, high-risk sources of CE, and SVO were more common in males. LAA and SVO showed an increasing frequency with age. No significant etiologic distribution differences were found amongst southern, central, or northern Europe.

CONCLUSIONS

The etiology of IS in young adults has clear gender-specific patterns that change with age. A notable portion of these patients remains without an evident stroke mechanism according to TOAST criteria.

Cerebral infarction in a case of Parry-Romberg syndrome

Our objective is to report a rare coexistence of Parry-Romberg disease and ischemic stroke. Here, we report the case of a 34-year-old woman with Parry-Romberg syndrome who developed cerebral infarction. This patient developed sudden left-sided weakness and was admitted to our hospital. Magnetic resonance imaging revealed acute cerebral infarction in the posterior limb of the right internal capsule. The patient had been diagnosed with Parry-Romberg syndrome at the age of 12, and she had a history of migraine without aura. Transesophageal echocardiography revealed a patent foramen ovale, but no atrial septal aneurysm or deep vein thrombosis was observed in the lower extremities. She was treated with 200 mg of aspirin and 10 mg of atorvastatin. Her symptoms gradually improved, and she was discharged 10 days after admission. Parry-Romberg syndrome is a rare disease of progressive hemifacial atrophy with unknown etiology. The potential risk factors for ischemic stroke in Parry-Romberg syndrome include ipsilateral cerebrovascular abnormality or migraine. In addition, patent foramen ovale was identified as a concomitant risk factor in our case.

Long-term cognitive impairment after first-ever ischemic stroke in young adults

BACKGROUND AND PURPOSE

Up to 14% of all ischemic strokes occur in young adults (<50 years). Poststroke cognitive performance is a decisive determinant of their quality of life. However, virtually no studies report on cognition after young stroke, especially not on the long term. This long-term perspective is important because young patients have a long life expectancy during which they start forming a family, have an active social life, and make decisive career moves. We aimed to evaluate the long-term cognitive outcome.

METHODS

All consecutive patients between January 1, 1980, and November 1, 2010, with a first-ever young ischemic stroke were recruited for cognitive assessment, using a matched stroke-free population as a reference. Composite Z scores for 7 cognitive domains were calculated and the ANCOVA model was used (Bonferroni correction). A below average performance was defined as >1.0 SD below the age-adjusted mean of the controls and cognitive impairment as >1.5 SD.

RESULTS

Two hundred seventy-seven patients and 146 matched controls completed cognitive assessment (mean follow-up, 11.0 years, SD, 8.2; age, 50.9 years, SD, 10.3). Long-term cognitive outcome after an ischemic stroke was worse in most cognitive domains compared with a nonstroke population. Up to 50% of the patients had a below average performance or cognitive impairment. Deficits in processing speed, working memory, and attention were most common.

CONCLUSIONS

Even 11 years after ischemic stroke in young adults, a substantial proportion of patients must cope with permanent cognitive deficits. These results have implications for information given to patients and rehabilitation services.

Trends in substance abuse preceding stroke among young adults: a population-based study

BACKGROUND AND PURPOSE

Approximately 5% of strokes occur in adults aged 18 to 44 years. Substance abuse is a prevalent risk factor for stroke in young adults. We sought to identify trends in substance abuse detection among stroke patients.

METHODS

Using a population-based design, we sought to identify all patients aged 18 to 54 years experiencing a stroke (ischemic or hemorrhagic) in the Greater Cincinnati and Northern Kentucky Study region during 1993 to 1994, 1999, and 2005. Demographic and clinical characteristics and substance use data were obtained retrospectively from chart review and adjudicated by physicians.

RESULTS

The number of young patients identified with a stroke increased from 1993 to 1994 (297) to 2005 (501). Blacks (61% vs 51%; P<0.02) and men (61% vs 47%; P<0.002) reported substance abuse (current smoking, alcohol, or illegal drug use) more frequently than did whites and women. Overall use of substances increased across study periods, 45% in 1993 versus 62% in 2005 (P=0.003). The trend was significant for illegal drug use (3.8% in 1993 vs 19.8% in 2005) and ever smoking (49% in 1993 vs 66% in 2005). Documentation of both cocaine and marijuana use increased over time. In 2005, half of young adults with a stroke were current smokers, and 1 in 5 abused illegal drugs.

CONCLUSIONS

Substance abuse is common in young adults experiencing a stroke. The observed increase in substance abuse is contributing to the increased incidence of stroke in young adults. Patients aged younger than 55 years who experience a stroke should be routinely screened and counseled regarding substance abuse.
