The age of patients presenting with complex arrhythmias is increasing. Frailty is a multifaceted syndrome characterized by an increased vulnerability to stressors and a decreased ability to maintain homeostasis. The prevalence of frailty is associated with age. The aims of this European Heart Rhythm Association (EHRA) EP Wire survey were to evaluate the proportion of patients with frailty and its influence on the clinical management of arrhythmias. A total of 41 centres-members of the EHRA Electrophysiology Research Network-in 14 European countries completed the web-based questionnaire in June 2017...

BACKGROUND: Cerebral microinfarcts (CMIs) are small ischemic lesions that are a common neuropathological finding in patients with stroke or dementia. CMIs in the cortex can now be detected in vivo on 3 Tesla MRI. OBJECTIVE: To determine the occurrence of CMIs and associated clinical features in patients with possible vascular cognitive impairment (VCI). METHOD: 182 memory-clinic patients (mean age 71.4±10.6, 55% male) with vascular injury on brain MRI (i...

BACKGROUND: Digital Clock Drawing Test (dCDT) technology enables the examination of detailed neurocognitive behavior as behavior unfolds in in real time; a capability that cannot be obtained using a traditional pen and paper testing format. OBJECTIVE: Parameters obtained from the dCDT were used to investigate neurocognitive constructs related to higher-order neurocognitive decision-making and information processing speed. The current research sought to determine the effect of age as related to combined motor and non-motor components of drawing, and higher-order, decision-making latencies...

Stroke patients have an elevated risk of developing long-term cognitive disorders or dementia. The latter is often associated with atrophy of the medial temporal lobe. However, it is not clear whether hippocampal and entorhinal cortex atrophy is the sole predictor of long-term post-stroke dementia. We hypothesized that hippocampal deformation (rather than atrophy) is a predictive marker of long-term post-stroke dementia on a rat model and tested this hypothesis in a prospective cohort of stroke patients.Male Wistar rats were subjected to transient middle cerebral artery occlusion and assessed 6 months later...

Thyroid hormone (TH) is crucial during neurodevelopment, but high levels of TH have been linked to neurodegenerative disorders. No data on the association of thyroid function with brain imaging in the general population are available. We therefore investigated the association of thyroid-stimulating hormone and free thyroxine (FT4) with magnetic resonance imaging (MRI)-derived total intracranial volume, brain tissue volumes, and diffusion tensor imaging measures of white matter microstructure in 4683 dementia- and stroke-free participants (mean age 60...

Background -Increased risk of dementia after myocardial infarction (MI) may be mediated by shared risk factors (e.g., atherosclerosis) and post-MI stroke. We examined risk of dementia in 1-year survivors of MI. Methods -Using Danish medical registries, we conducted a nationwide population-based cohort study of all patients with first-time MI and a sex-, birth year-, and calendar year-matched general population comparison cohort without MI (1980-2012). Cox regression analysis was used to compute 1-35 year adjusted hazard ratios (aHRs) for dementia, controlled for matching factors and adjusted for comorbidities and socioeconomic status...

OBJECTIVE: Anosognosia, or impaired illness awareness, is a common feature of Alzheimer's disease (AD) and less so of mild cognitive impairment (MCI). Importantly, anosognosia negatively influences clinical outcomes for patients and their caregivers and may predict the conversion from MCI to AD. This study aimed to examine (1) the relationship between brain glucose metabolism as measured by fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) and anosognosia in patients with MCI and AD and (2) the predictive utility of anosognosia in patients with MCI for later conversion to AD, even when controlling for other factors, including gender, education, apolipoprotein E ε4 carrier status, dementia severity, and cognitive dysfunction...

BACKGROUND: Most data on the clinical epidemiology of atrial fibrillation (AF) comes from Western populations, and data for Asians are limited. We investigated the lifetime risk and projected number of AF among Asians. The annual risks of adverse events amongst AF patients, time trends and the risks compared to non-AF patients were analyzed. METHODS: From year 2000 to 2011, 289,559 patients aged ≥ 20 years experienced new-onset AF in Taiwan. The incidence, prevalence and lifetime risk of AF were calculated...

Cerebral amyloid angiopathy is diagnosed in stroke units after lobar intracerebral hemorrhage. CAA can also be diagnosed in memory clinics when patients are referred for cognitive impairment assessment, and may be a reason for admission to emergency or neurology departments because of rapidly progressive cognitive or neurological decline, or a transient focal neurological episode. CAA may even be observed in older community-dwelling individuals. Neuropsychological impairment in CAA has been described over the past 20 years...

BACKGROUND: An increasing amount of evidence suggests an association between epilepsy and multiple somatic and psychiatric conditions, which is more significant than in the general population. Furthermore, a bidirectional association has been established between epilepsy and several conditions, notably depression and suicide, cerebrovascular disease, stroke, dementia and migraine, which is best explained by the presence of common underlying mechanisms and risk factors. Gaining knowledge about these common mechanisms can provide insight into new therapeutic targets, screening and preventive measures...

Butylphthalide, a component extracted from seeds of Chinese celery, is an effective neuroprotective agent used for the treatment of ischemic stroke and dementia. Diabetes may cause central nervous system damage, and diabetes is closely associated with dementia. The aim of the present study was to investigate the effects of butylphthalide on cognitive impairment in a streptozotocin‑induced diabetic rat model, and the underlying mechanisms of action. A total of 30 healthy male Sprague Dawley rats were randomly divided into the following 2 groups: Normal control (NC; n=10) and diabetes model (DM) groups (n=20)...

OBJECTIVES/HYPOTHESIS: Aspiration of gastric refluxate is one of the most commonly observed complications among long-term nasogastric tube (NGT) fed patients. The upper esophageal sphincter (UES) pressure barrier is the main defense mechanism against pharyngeal reflux of gastric contents. Our objective was to investigate the efficacy and safety of the UES assist device (UES-AD) in preventing gastric reflux through the UES in long-term NGT-fed patients. STUDY DESIGN: Self-Controlled Case series...

Palliative medicine is a specialty that focuses on improving the quality of life for patients with serious or advanced medical conditions, and it is appropriate at any stage of disease, including at the time of diagnosis. Neurologic conditions tend to have high symptom burdens, variable disease courses, and poor prognoses that affect not only patients but also their families and caregivers. Patients with a variety of neurologic conditions such as Parkinson disease, dementia, amyotrophic lateral sclerosis, brain tumors, stroke, and acute neurologic illnesses have substantial unmet needs that can be addressed through a combination of primary and specialty palliative care...

The brain is highly susceptible to injury caused by hypertension because the increased blood pressure causes artery remodeling that can limit cerebral perfusion. Mineralocorticoid receptor (MR) antagonism prevents hypertensive cerebral artery remodeling, but the vascular cell types involved have not been defined. In the periphery, the endothelial MR mediates hypertension-induced vascular injury, but cerebral and peripheral arteries are anatomically distinct; thus, these findings cannot be extrapolated to the brain...

Increasing evidence suggests that vascular risk factors contribute to neurodegeneration, cognitive impairment and dementia. While there is considerable overlap between features of vascular cognitive impairment and dementia (VCID) and Alzheimer's disease (AD), it appears that cerebral hypoperfusion is the common underlying pathophysiological mechanism which is a major contributor to cognitive decline and degenerative processes leading to dementia. Sustained cerebral hypoperfusion is suggested to be the cause of white matter attenuation, a key feature common to both AD and dementia associated with cerebral small vessel disease (SVD)...
