- Background: Cardiovascular diseases are leading causes of death and patients with dementia are often affected by them. Objective: Investigate associations of cardiovascular diseases with different dementia disorders and determine their impact on mortality. Methods: This study included 29,630 patients from the Swedish Dementia Registry (mean age 79 years, 59% women) diagnosed with Alzheimer's disease (AD), mixed dementia, vascular dementia, dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD), frontotemporal dementia (FTD), or unspecified dementia. Records of cardiovascular diseases come from the Swedish National Patient Register. Multinomial logistic regression and cox proportional hazard models were applied. Results: Compared to AD, we found a higher burden of all cardiovascular diseases in mixed and vascular dementia. Cerebrovascular diseases were more associated with DLB than with AD. Diabetes mellitus was less associated with PDD and DLB than with AD. Ischemic heart disease was less associated with PDD and FTD than AD. All cardiovascular diseases predicted death in patients with AD, mixed, and vascular dementia. Only ischemic heart disease significantly predicted death in DLB patients (HR = 1.72; 95% CI = 1.16-2.55). In PDD patients, heart failure and diabetes mellitus were associated with a higher risk of death (HR = 3.06; 95% CI = 1.74-5.41 and HR = 3.44; 95% CI = 1.31-9.03). In FTD patients, ischemic heart disease and atrial fibrillation or flutter significantly predicted death (HR = 2.11; 95% CI = 1.08-4.14 and HR= 3.15; 95% CI = 1.60-6.22, respectively). Conclusion: Our study highlights differences in the occurrence and prognostic significance of cardiovascular diseases in several dementia disorders. This has implications for the care and treatment of the different dementia disorders.

- Introduction: Administration of several cardiovascular drugs has an effect on dementia. We aimed to investigate whether there are differences in the use of cardiovascular medication between different dementia disorders. Methods: We obtained information about dementia patients from the Swedish Dementia Registry. Patients were diagnosed with one of these dementia disorders: Alzheimer's disease (n = 8,139), mixed dementia (n = 5,203), vascular dementia (n = 4,982), Lewy body dementia (n = 605), frontotemporal dementia (n = 409) and Parkinson's disease dementia (n = 405). Multivariate logistic regression analysis was performed to investigate the association between use of cardiovascular medication and dementia disorders, after adjustment for age, gender, living alone, cognitive status and total number of drugs (a proxy for overall co-morbidity). Results: Seventy percent of all the dementia patients used cardiovascular medication. Use of cardiovascular drugs is common in patients with vascular and mixed dementia. Male gender, higher age, slightly better cognitive status and living with another person was associated with use of cardiovascular medication. Conclusions: Cardiovascular medication is used extensively across dementia disorders and particularly in vascular and mixed dementia. Future research should investigate the tolerability and effectiveness of these drugs in the different dementia disorders.

- AimsHeart failure (HF) and dementia frequently coexist, but little is known about their types, relationships to each other and prognosis. The aims were to (i) describe patients with HF and dementia, assess (ii) the proportion of specific dementia disorders in types of HF based on ejection fraction and (iii) the prognostic role of types of HF and dementia disorders. Methods and resultsThe Swedish Heart Failure Registry (RiksSvikt) and The Swedish Dementia Registry (SveDem) were record-linked. Associations between dementia disorders and HF types were assessed with multinomial logistic regression and survival was investigated with Kaplan-Meier analysis and multivariable Cox regression. We studied 775 patients found in both registries (55% men, mean age 82years). Ejection fraction was preserved in 38% of patients, reduced in 34%, and missing in 28%. The proportions of dementia disorders were similar across HF types. Vascular dementia was the most common dementia disorder (36%), followed by other dementias (28%), mixed dementia (20%), and Alzheimer disease (16%). Over a mean follow-up of 1.5years, 76% of patients survived 1year. We observed no significant differences in survival with regard to HF type (P=0.2) or dementia disorder (P=0.5). After adjustment for baseline covariates, neither HF types nor dementia disorders were independently associated with survival. ConclusionsHeart failure with preserved ejection fraction was the most common HF type and vascular dementia was the most common dementia disorder. The proportions of dementia disorders were similar across HF types. Neither HF types nor specific dementia disorders were associated with survival.

- Objectives: We aimed to (1) study factors that determine the use of invasive procedures in the management of acute myocardial infarction (AMI) in patients with dementia and (2) determine whether the use of invasive procedures was associated with their better survival. Design: Cohort study based on patients registered in the Swedish Dementia Registry (SveDem), 20072012. Median follow-up time was 228 days. Setting: Patients diagnosed with dementia in specialist memory clinics and primary care units in Sweden. Participants: A total of 525 patients with dementia who suffered AMI (mean age 89 years, 54% women). Measurements: Information on AMI and use of invasive procedures (coronary angiography and percutaneous coronary intervention) was obtained from Swedish national health registers. Binary logistic regression was applied to study associations of patients characteristics with the use of invasive procedures; odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Survival was analyzed with Kaplan-Meier curves; log-rank test was used to compare survival of patients who received an invasive procedure versus those who did not receive it. Cox regression was applied to study association of the invasive procedures with all-cause mortality; hazard ratios (HRs) with 95% CIs were calculated. Results: One hundred ten patients (21%) with dementia received an invasive procedure in the management of AMI. After multivariate adjustment, lower age and higher global cognitive status were associated with the use of invasive procedures. The invasively managed patients survived longer (P = .001). The use of invasive procedures was associated with a lower risk of all-cause mortality, adjusting for type of AMI and dementia disorder, age, gender, registration unit, history of AMI and comorbidity score (HR 0.35, 95% CI 0.21-0.59), or total number of drugs (HR 0.34, 95% CI 0.20-0.58). Conclusion: Age and cognitive status determine the use of invasive procedures in patients with dementia. This study suggests that the invasive management of AMI has a benefit for survival of patients with dementia. (C) 2016 AMDA - The Society for Post-Acute and Long-Term Care Medicine.

- Background and objective. The number of elderly persons in society is increasing, placing additional demands on the public health system. Extensive use of drugs is common in the elderly, and in patients with dementia this further increases their vulnerability. Since 1998 the municipality of Kalmar, Sweden, has worked with a dementia management programme that focuses on early intervention in order to identify the patient's help needs at an early stage. An important part of the programme aims at optimizing pharmacological treatment. The objective of the present study is to evaluate whether the dementia programme had a secondary effect on the use of psychotropic medication in the elderly population in general. Design and setting. A retrospective, drug utilization study analysing the use of selected drug categories by the elderly (75 years and older) in the Kalmar municipality compared with the whole of Sweden. Results and conclusions. The results suggest that the dementia programme contributed to an improvement in psychotropic drug use in the elderly as a secondary effect. Furthermore, the implementation of this programme did not require allocation of extra funding.

- OBJECTIVE We aimed to investigate the differences in clinical characteristics and pharmacological treatment associated with the presence of diabetes in a large cohort of patients with dementia.RESEARCH DESIGN AND METHODS A cross-sectional registry-based study was conducted using data from the Swedish Dementia Registry (SveDem). Data on dementia diagnosis, dementia type, and demographic determinants were extracted from SveDem. Data from the Swedish Patient Register and Prescribed Drug Register were combined for the diagnosis of diabetes. Data on antidiabetic, dementia, cardiovascular, and psychotropic medications were extracted from the Swedish Prescribed Drug Register. Logistic regression was used to determine whether the variables were associated with diabetes after adjustment for confounders. In total, 29,630 patients were included in the study, and 4,881 (16.5%) of them received a diagnosis of diabetes.RESULTS In the fully adjusted model, diabetes was associated with lower age at dementia diagnosis (odds ratio [OR] 0.97 [99% CI 0.97-0.98]), male sex (1.41 [1.27-1.55]), vascular dementia (1.17 [1.01-1.36]), and mixed dementia (1.21 [1.06-1.39]). Dementia with Lewy bodies (0.64 [0.44-0.94]), Parkinson disease dementia (0.46 [0.28-0.75]), and treatment with antidepressants (0.85 [0.77-0.95]) were less common among patients with diabetes. Patients with diabetes who had Alzheimer disease obtained significantly less treatment with cholinesterase inhibitors (0.78 [0.63-0.95]) and memantine (0.68 [0.54-0.85]).CONCLUSIONS Patients with diabetes were younger at dementia diagnosis and obtained less dementia medication for Alzheimer disease, suggesting less optimal dementia treatment. Future research should evaluate survival and differences in metabolic profile in patients with diabetes and different dementia disorders.

- Background: The societal costs of Alzheimer's Disease (AD) are enormous and pose a great challenge for the health and social care in any society. It is of vital importance to develop and identify cost effective treatment. The aim of the study was to present a hypothetical economic model of Disease Modifying Treatment (DMT) in AD. Methods: A 20 year Markov cohort model of DMT was constructed, based on Swedish care conditions. States and progression were defined according to the Mini Mental State Examination (MMSE). Epidemiological studies of incidence of dementia, prevalence and costs of Mild Cognitive Impairment (MCI) and AD as well as conversion studies of MCI and demographic statistics were used as inputs in the model. Results: Total costs were 113,797 million SEK for patients treated with DMT vs 88,562 million SEK for untreated patients. The corresponding gained QALYs were 529,945 and 450,307 respectively, giving an incremental cost effectiveness ratio of 293,002 SEK/QALY in the base option. Survival in the model was 8.72 years with DMT and 7.77 years for untreated. With an assumed Willingness to pay (WTP) of 600,000 SEK (about 86,200 US$ and 62,000 €) per gained QALY, the model indicated cost effectiveness with DMT. The sensitivity analysis implied no cost savings with DMT, but most options indicated cost effectiveness vs. the chosen WTP. Conclusion: The main reasons for the higher costs with DMT were the costs of DMT itself and the prolonged survival with DMT. Even if costs increase with DMT, the model indicates cost effectiveness.

- Background: Patients with dementia might have higher risk for hemorrhagic complications with anticoagulant therapy prescribed for atrial fibrillation (AF).Objective: This study assesses the risks and benefits of warfarin, antiplatelets, and no treatment in patients with dementia and AF.Methods: Of 49,792 patients registered in the Swedish Dementia Registry 2007-2014, 8,096 (16%) had a previous diagnosis of AF. Cox proportional hazards models were used to calculate the risk for ischemic stroke (IS), nontraumatic intracranial hemorrhage, any-cause hemorrhage, and death.Results: Out of the 8,096 dementia patients with AF, 2,143 (26%) received warfarin treatment, 2,975 (37%) antiplatelet treatment, and 2,978 (37%) had no antithrombotic treatment at the time of dementia diagnosis. Patients on warfarin had fewer IS than those without treatment (5.2% versus 8.7%; p < 0.001) with no differences compared to antiplatelets. In adjusted analyses, warfarin was associated with a lower risk for IS (HR 0.76, CI 0.59-0.98), while antiplatelets were associated with increased risk (HR 1.25, CI 1.01-1.54) compared to no treatment. For any-cause hemorrhage, there was a higher risk with warfarin (HR 1.28, CI 1.03-1.59) compared to antiplatelets. Warfarin and antiplatelets were associated with a lower risk for death compared to no treatment.Conclusions: Warfarin treatment in Swedish patients with dementia is associated with lower risk of IS and mortality, and a small increase in any-cause hemorrhage. This study supports the use of warfarin in appropriate cases in patients with dementia. The low percentage of patients on warfarin treatment indicates that further gains in stroke prevention are possible.

- BACKGROUND: Previous studies have shown that patients with dementia receive less testing and treatment for stroke.OBJECTIVES: Our aim was to investigate hospital management of acute ischemic stroke in patients with and without dementia.METHODS: Retrospective analysis of prospectively collected data 2010-2014 from the Swedish national dementia registry (SveDem) and the Swedish national stroke registry (Riksstroke). Patients with dementia who suffered an acute ischemic stroke (AIS) (n = 1,356) were compared with matched non-dementia AIS patients (n = 6,755). Outcomes included length of stay in a stroke unit, total length of hospitalization, and utilization of diagnostic tests and assessments.RESULTS: The median age at stroke onset was 83 years. While patients with dementia were equally likely to be directly admitted to a stroke unit as their non-dementia counterparts, their stroke unit and total hospitalization length were shorter (10.5 versus 11.2 days and 11.6 versus 13.5, respectively, p < 0.001). Dementia patients were less likely to receive carotid ultrasound (OR 0.36, 95% CI [0.30-0.42]) or undergo assessments by the interdisciplinary team members (physiotherapists, speech therapists, occupational therapists; p < 0.05 for all adjusted models). However, a similar proportion of patients received CT imaging (97.4% versus 98.6%, p = 0.001) and a swallowing assessment (90.7% versus 91.8%, p = 0.218).CONCLUSIONS: Patients with dementia who suffer an ischemic stroke have equal access to direct stroke unit care compared to non-dementia patients; however, on average, their stay in a stroke unit and total hospitalization are shorter. Dementia patients are also less likely to receive specific diagnostic tests and assessments by the interdisciplinary stroke team.

- OBJECTIVE: To compare access to intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) and its outcomes in patients with and without dementia.METHODS: This was a longitudinal cohort study of the Swedish dementia and stroke registries. Patients with preexisting dementia who had AIS from 2010 to 2014 (n = 1,356) were compared with matched patients without dementia (n = 6,755). We examined access to thrombolysis and its outcomes at 3 months (death, residency, and modified Rankin Scale [mRS] score). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated with logistic and ordinal logistic regression.RESULTS: < 0.001). Unfavorable outcomes with an mRS score of 5 to 6 were doubled in patients with dementia (56.1% vs 28.1%).CONCLUSIONS: Younger patients with dementia and AIS are less likely to receive IVT. Among patients receiving thrombolysis, there are no differences in sICH or death, although patients with dementia have worse accommodation and functional outcomes at 3 months.
