  • Temporal Trends of Stroke Epidemiology in Southern Sweden : A Population-Based Study on Stroke Incidence and Early Case-Fatality
  • 2018
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 0251-5350 .- 1423-0208. ; 50:3-4, s. 174-182
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Up-to-date epidemiological stroke studies are important for healthcare planning and evaluating prevention strategies. This population-based study investigates temporal trends in stroke incidence and case-fatality in southern Sweden. Methods: First-ever stroke cases in the local catchment area of Skåne University Hospital in Lund, Sweden, between March, 2015 and February, 2016, were included from several sources, including 2 prospective hospital-based registers, retrospective screening of primary care visits, and autopsy registers. Stroke incidence and 28-day case-fatality rates were compared with data from this area obtained through similar methodology between March, 2001 and February, 2002. Results: Altogether, 456 and 413 first-ever stroke patients were identified during the earlier and later time periods respectively. The age- and sex-standardized stroke incidence rates decreased from 246 (95% CI 224–270) to 165 (95% CI 149–182) per 100,000 people. However, incidence remained unaltered among those <65 years. Early case-fatality decreased from 14 to 11% (p = 0.165). ­Conclusion: First-ever stroke incidence in southern Sweden has decreased to 33% since the beginning of this millennium. Incidence rates have decreased among the elderly but remain unchanged among younger age groups. Our findings warrant further studies on trends in risk factor profiles and effects of prevention strategies, and heightened focus on stroke in the young.

  • Validation of Diagnoses of Transient Ischemic Attack in the Swedish Stroke Register (Riksstroke) TIA-Module
  • 2015
  • Ingår i: Neuroepidemiology. - : S. Karger. - 0251-5350 .- 1423-0208. ; 45:1, s. 40-43
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: In 2010, the Swedish Stroke Register (Riksstroke; RS) established a module for transient ischemic attacks (RS-TIA). We report a diagnostic validation study of patients included in RS-TIA.Methods: During the first year, 7,825 patients were registered at 59 out of 74 Swedish hospitals. A time-based TIA definition was applied. A sample of 180 patients (30 patients each from 6 hospitals), with a similar distribution of age and sex as in RS-TIA, was prepared. Two independent observers assessed medical records for quality of documentation and assigned a diagnosis of likely, possible, unlikely TIA or ischennic stroke, according to pre-specified criteria.Results:The 2 observers agreed in 77% of cases that the event was a likely or possible TIA, in 3% that the event was an ischemic stroke, and in 2% that the event was an unlikely TIA. The observers disagreed in 8% of patients on TIA vs. ischennic stroke, and in 11% on a vascular vs. non-vascular cause. Quality of documentation was fair.Conclusions: There was interobserver agreement on diagnosis of TIA in the majority of patients included in RS-TIA. Diagnostic accuracy may be further improved by more systematic documentation of symptoms and signs.

  • Diverging Trends in the Incidence of Spontaneous Intracerebral Hemorrhage in Sweden 2010-2019 : An Observational Study from the Swedish Stroke Register (Riksstroke)
  • 2023
  • Ingår i: Neuroepidemiology. - 0251-5350. ; 57:6, s. 367-376
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Although ischemic stroke incidence has decreased in Sweden over the past decade, trends in spontaneous intracerebral hemorrhage (ICH) incidence are less well delineated. In this time period, there has been a dramatic increase in use of oral anticoagulants (OAC). The aim of our study was to investigate incidence trends in spontaneous first-ever ICH in Sweden between 2010 and 2019, with a focus on non-OAC-associated and OAC-associated ICH. Methods: We included patients (≥18 years) with first-ever ICH registered in the hospital-based Swedish Stroke Register (Riksstroke) 2010-2019. Data were stratified by non-OAC and OAC ICH and analyzed for 2010-2012, 2013-2016, and 2017-2019. Incidence rates are shown as crude and age-specific per 100,000 person-years. Results: Between 2010 and 2019, 22,289 patients with first-ever ICH were registered; 18,325 (82.2%) patients with non-OAC ICH and 3,964 (17.8%) patients with OAC ICH. Annual crude incidence (per 100,000) of all first-ever ICH decreased by 10% from 29.5 (95% CI 28.8-30.3) to 26.7 (95% CI 26.0-27.3) between 2010-2012 and 2017-2019. The crude incidence rate of non-OAC ICH decreased by 20% from 25.7 (95% CI 25.0-26.3) to 20.7 (95% CI 20.1-21.2), whereas OAC ICH increased by 56% from 3.86 (95% CI 3.61-4.12) to 6.01 (95% CI 5.70-6.32). The proportion of OAC ICH of all first-ever ICH increased between 2010-2012 and 2017-2019 from 13.1% to 22.5% (p < 0.001). Proportional changes were largest in the age group ≥85 years with a decrease in non-OAC ICH by 32% from 155 (95% CI 146-164) to 106 (95% CI 98.6-113) and an increase in OAC ICH by 155% from 25.7 (95% CI 22.1-29.4) to 65.5 (95% CI 59.9-71.2). Conclusion: Incidence of first-ever ICH in Sweden decreased by 10% between 2010 and 2019. We found diverging trends with a 20% decrease in non-OAC-associated ICH and a 56% increase in OAC-associated ICH. Further research on ICH epidemiology, analyzing non-OAC and OAC-associated ICH separately, is needed to follow up these diverging trends including underlying risk factors.

  • Epidemiology of First and Recurrent Ischemic Stroke in Sweden 2010-2019 : A Riksstroke Study
  • 2023
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 0251-5350 .- 1423-0208. ; 56:6, s. 433-442
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Ischemic stroke incidence appears to have decreased during the last decades, but most studies focus on the first-ever events and epidemiological data on recurrent stroke are scarce. The aim of our study was to investigate trends in incidence, risk factors, and medication in patients with first-ever and recurrent ischemic stroke between 2010 and 2019 in Sweden. Methods: We included patients (≥18 years old) with ischemic stroke registered in the hospital-based Swedish Stroke Register (Riksstroke) 2010-2019. The coverage of Riksstroke was consistently high (about 90%) during this period. Data were stratified by first-ever and recurrent ischemic stroke in three different time periods (2010-2012, 2013-2016, and 2017-2019) and shown as crude and age-specific incidence rates per 100,000 person-years. Statistics Sweden provided census data on the Swedish population in different age groups. Results: During the study period, 201,316 cases of ischemic stroke were registered in Riksstroke, including 153,865 (76.4%) cases of first-ever ischemic stroke and 46,248 (23.0%) cases of recurrent ischemic stroke (0.6% of cases unclassified). The crude incidence of first-ever ischemic stroke decreased by 17% from 216 (95% CI 214-218) to 179 (95% CI 177-181) between 2010-2012 and 2017-2019, whereas recurrent ischemic stroke decreased by 33% from 72 (95% CI 71-73) to 48 (95% CI 47-49). Between these time periods, diminishing ischemic stroke incidence was seen in all age groups with highest decline noted in those aged 75-84 years (928 [95% CI 914-943] to 698 [95% CI 686-709];-25% in first-ever ischemic stroke and 361 [95% CI 351-370] to 219 [95% CI 213-226];-39% in recurrent ischemic stroke) and ≥85 years (1,674 [95% CI 1,645-1,703] to 1,295 [95% CI 1,270-1,320];-23% in first-ever ischemic stroke and 683 [95% CI 664-702] to 423 [95% CI 409-437];-38% in recurrent ischemic stroke). Treatment with anticoagulants in patients with atrial fibrillation and lipid-lowering drugs increased considerably in patients with first-ever and recurrent ischemic stroke both at admission and discharge during the study period. Conclusion: Whereas both first-ever and recurrent ischemic stroke rates declined in Sweden between 2010 and 2019, the proportional decline was almost double for recurrent ischemic stroke than for first-ever ischemic stroke and most pronounced in the elderly. Increased use of secondary preventive drugs, in particular anticoagulants in atrial fibrillation, appears to have contributed, but further studies on precise causes for the decline in recurrent ischemic stroke are needed.

  • Atlas of the Global Burden of Stroke (1990-2013): The GBD 2013 Study
  • 2015
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 1423-0208 .- 0251-5350. ; 45:3, s. 230-236
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: World mapping is an important tool to visualize stroke burden and its trends in various regions and countries. Objectives: To show geographic patterns of incidence, prevalence, mortality, disability-adjusted life years (DALYs) and years lived with disability (YLDs) and their trends for ischemic stroke and hemorrhagic stroke in the world for 1990-2013. Methodology: Stroke incidence, prevalence, mortality, DALYs and YLDs were estimated following the general approach of the Global Burden of Disease (GBD) 2010 with several important improvements in methods. Data were updated for mortality (through April 2014) and stroke incidence, prevalence, case fatality and severity through 2013. Death was estimated using an ensemble modeling approach. A new software package, DisMod-MR 2.0, was used as part of a custom modeling process to estimate YLDs. All rates were age-standardized to new GBD estimates of global population. All estimates have been computed with 95% uncertainty intervals. Results: Age-standardized incidence, mortality, prevalence and DALYs/YLDs declined over the period from 1990 to 2013. However, the absolute number of people affected by stroke has substantially increased across all countries in the world over the same time period, suggesting that the global stroke burden continues to increase. There were significant geographical (country and regional) differences in stroke burden in the world, with the majority of the burden borne by low- and middle-income countries. Conclusions: Global burden of stroke has continued to increase in spite of dramatic declines in age-standardized incidence, prevalence, mortality rates and disability. Population growth and aging have played an important role in the observed increase in stroke burden.

  • Update on the Global Burden of Ischemic and Hemorrhagic Stroke in 1990-2013: The GBD 2013 Study
  • 2015
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 1423-0208 .- 0251-5350. ; 45:3, s. 161-176
  • Tidskriftsartikel (refereegranskat)abstract
    • <b><i>Background:</i></b> Global stroke epidemiology is changing rapidly. Although age-standardized rates of stroke mortality have decreased worldwide in the past 2 decades, the absolute numbers of people who have a stroke every year, and live with the consequences of stroke or die from their stroke, are increasing. Regular updates on the current level of stroke burden are important for advancing our knowledge on stroke epidemiology and facilitate organization and planning of evidence-based stroke care. <b><i>Objectives:</i></b> This study aims to estimate incidence, prevalence, mortality, disability-adjusted life years (DALYs) and years lived with disability (YLDs) and their trends for ischemic stroke (IS) and hemorrhagic stroke (HS) for 188 countries from 1990 to 2013. <b><i>Methodology:</i></b> Stroke incidence, prevalence, mortality, DALYs and YLDs were estimated using all available data on mortality and stroke incidence, prevalence and excess mortality. Statistical models and country-level covariate data were employed, and all rates were age-standardized to a global population. All estimates were produced with 95% uncertainty intervals (UIs). <b><i>Results:</i></b> In 2013, there were globally almost 25.7 million stroke survivors (71% with IS), 6.5 million deaths from stroke (51% died from IS), 113 million DALYs due to stroke (58% due to IS) and 10.3 million new strokes (67% IS). Over the 1990-2013 period, there was a significant increase in the absolute number of DALYs due to IS, and of deaths from IS and HS, survivors and incident events for both IS and HS. The preponderance of the burden of stroke continued to reside in developing countries, comprising 75.2% of deaths from stroke and 81.0% of stroke-related DALYs. Globally, the proportional contribution of stroke-related DALYs and deaths due to stroke compared to all diseases increased from 1990 (3.54% (95% UI 3.11-4.00) and 9.66% (95% UI 8.47-10.70), respectively) to 2013 (4.62% (95% UI 4.01-5.30) and 11.75% (95% UI 10.45-13.31), respectively), but there was a diverging trend in developed and developing countries with a significant increase in DALYs and deaths in developing countries, and no measurable change in the proportional contribution of DALYs and deaths from stroke in developed countries. <b><i>Conclusion:</i></b> Global stroke burden continues to increase globally. More efficient stroke prevention and management strategies are urgently needed to halt and eventually reverse the stroke pandemic, while universal access to organized stroke services should be a priority.

  • Accuracy and Sensitivity of Parkinsonian Disorder Diagnoses in Two Swedish National Health Registers
  • 2012
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 1423-0208 .- 0251-5350. ; 38:3, s. 186-193
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Swedish population-based national health registers are widely used data sources in epidemiological research. Register-based diagnoses of Parkinson's disease have not been validated against clinical information. Methods: Parkinson's disease (PD) and other parkinsonian disorder diagnoses were ascertained in two registers, i.e. the National Patient Register (NPR) and the Cause of Death Register (CDR). Diagnoses were validated in terms of accuracy (positive predictive value) and sensitivity against data from a population-based study of PD in 1998-2004 that screened more than 35,000 persons and identified 194 cases of parkinsonian disorders including 132 PD cases (the gold standard for the purposes of this study). Results: Accuracy for any parkinsonian disorder diagnoses was 88.0% in the NPR and 94.4% in the CDR. Accuracy of PD diagnoses was 70.8% in the NPR and 66.7% in the CDR. Misclassification between differential parkinsonian diagnoses was common. The accuracy of PD diagnoses in the NPR improved to 83.0% by restricting the definition to primary diagnoses only. The sensitivity of PD diagnoses in the NPR and CDR combined was 83.1%, with a mean time to detection of 6.9 years. Conclusions: Population-based national health registers are valid data sources in epidemiological studies of PD or parkinsonian disorder etiology but are less suitable in studies of incidence or prevalence.

  • Incidence of Aphasia in Ischemic Stroke
  • 2022
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 0251-5350 .- 1423-0208. ; 56:3, s. 174-182
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: A decrease in ischemic stroke (IS) incidence has been observed in high income countries during the last decades. Whether this has influenced the occurrence of aphasia in IS is uncertain. We therefore examined the incidence rate and potentially related determinants of aphasia in IS. Methods: We prospectively examined consecutive patients admitted to hospital with first-ever acute IS between March 1, 2017, and February 28, 2018, as part of the Lund Stroke Register (LSR) Study, comprising patients from the uptake area of Skåne University Hospital, Lund, Sweden. Patients were assessed with National Institutes of Health Stroke Scale (NIHSS) at stroke onset. Presence of aphasia was evaluated with NIHSS item 9 (language). We registered IS subtypes and risk factors. To investigate possible temporal changes in aphasia incidence, we made comparisons with corresponding LSR data from 2005 to 2006. Incidence rates were calculated and adjusted to the European Standard Population (ESP) and to the Swedish population. Results: Among 308 included IS patients, 30% presented with aphasia (n = 91; 95% CI: 25-35), a proportion of aphasia in IS that was similar to 2005-2006. The incidence rate of aphasia was 31 per 100,000 person-years adjusted to the ESP (95% CI: 25-38 per 100,000 person-years) corresponding to a significant decrease of 30% between 2005-2006 and 2017-2018. The decrease was significantly more pronounced in men. The initial severity of aphasia remained unchanged, with the majority of patients having severe to global aphasia. No significant differences between vascular stroke risk factors were noted among stroke patients with or without aphasia. Conclusion: Even though the overall IS incidence rate has decreased during the first decades of the 21st century, the proportion of IS patients with aphasia at stroke onset remains stable at 30%. Aphasia continues to be an important symptom that needs to be considered in stroke care and rehabilitation.

  • Occurrence of Depression in Families with Frontotemporal Dementia: A Family History Study.
  • 2009
  • Ingår i: Neuroepidemiology. - : S. Karger AG. - 1423-0208 .- 0251-5350. ; 33:2, s. 124-130
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: There are clinical similarities between frontotemporal dementia (FTD) and depression. The aim is to study co-aggregation of depression in families with FTD, indicating the existence of common aetiological factors. Methods: The study included 74 index patients with FTD and their 540 first-degree relatives above the age of 15 years. Occurrence of depression was studied at 3 different levels. Results: The incidence of depression in first-degree relatives of FTD patients was not higher than that of a general population. Occurrence of depression was not higher in families where parents had FTD compared to families with parents having no indications of FTD. Individuals with FTD had not suffered from depression to a greater extent than those without FTD. Conclusions: The hypothesis of a common aetiological factor of FTD and depression was not supported.
