Post-stroke dementia (PSD) or post-stroke cognitive impairment (PSCI) may affect up to one third of stroke survivors. Various definitions of PSCI and PSD have been described. We propose PSD as a label for any dementia following stroke in temporal relation. Various tools are available to screen and assess cognition, with few PSD-specific instruments. Choice will depend on purpose of assessment, with differing instruments needed for brief screening (e.g., Montreal Cognitive Assessment) or diagnostic formulation (e...

OBJECTIVES: Cognitive frailty, a condition describing the simultaneous presence of physical frailty and mild cognitive impairment, has been recently defined by an international consensus group. We estimated the predictive role of a "reversible" cognitive frailty model on incident dementia, its subtypes, and all-cause mortality in nondemented older individuals. We verified if vascular risk factors or depressive symptoms could modify this predictive role. DESIGN: Longitudinal population-based study with 3...

BACKGROUND: Cerebral small vessel disease (SVD) is the common cause of cognitive decline in the old population. MRI can be used to clarify its mechanisms. However, the surrogate markers of MRI for early cognitive impairment in SVD remain uncertain to date. We investigated the cognitive impacts of cerebral microbleeds (CMBs), diffusion tensor imaging (DTI), and brain volumetric measurements in a cohort of post-stroke non-dementia SVD patients. METHODS: Fifty five non-dementia SVD patients were consecutively recruited and categorized into two groups as no cognitive impairment (NCI) (n = 23) or vascular mild cognitive impairment (VaMCI) (n = 32)...

BACKGROUND: Neuropsychiatric symptoms are common manifestations of Alzheimer's disease (AD). A number of studies have targeted psychosis, i.e., hallucinations and delusions in AD, but few have assessed agitation/aggression in AD. OBJECTIVE: To investigate the risk factors and pathological substrates associated with presence [A(+)] and absence [A(-)] of agitation/aggression (A) in autopsy-confirmed AD. METHODS: Data was collected from the UDS data as of 2015 on the NACC database...

Alzheimer's disease (AD), the most common form of dementia, is a progressive disorder manifested by gradual memory loss and subsequent impairment in mental and behavioral functions. Though the primary risk factor for AD is advancing age, other factors such as diabetes mellitus, hyperlipidemia, obesity, vascular factors and depression play a role in its pathogenesis. The human gastrointestinal tract has a diverse commensal microbial population, which has bidirectional interactions with the human host that are symbiotic in health, and in addition to nutrition, digestion, plays major roles in inflammation and immunity...

INTRODUCTION: Dementia is a heterogeneous neurodegenerative disease, whose etiology results from a complex interplay between environmental and genetic factors. METHODS: We searched PubMed to identify meta-analyses of observational studies that examined associations between nongenetic factors and dementia. We estimated the summary effect size using random-effects and fixed-effects model, the 95% CI, and the 95% prediction interval. We assessed the between-study heterogeneity (I-square), evidence of small-study effects, and excess significance...

BACKGROUND/AIMS: Behavioral and psychological symptoms of dementia (BPSDs) negatively impact the prognosis of dementia patients and increase caregiver distress. The aims of this study were to clarify the differences of trajectories of 12 kinds of BPSDs by disease severity in four major dementias and to develop charts showing the frequency, severity, and associated caregiver distress (ACD) of BPSDs using the data of a Japan multicenter study (J-BIRD). METHODS: We gathered Neuropsychiatric Inventory (NPI) data of patients with Alzheimer's disease (AD; n = 1091), dementia with Lewy bodies (DLB; n = 249), vascular dementia (VaD; n = 156), and frontotemporal lobar degeneration (FTLD; n = 102) collected during a 5-year period up to July 31, 2013 in seven centers for dementia in Japan...

Late-onset depression (LOD) is defined as depression manifesting for the first time in later life. Up to now, there has been no exact definition of the lower age limit for LOD. Psychopathological symptoms of LOD do not fundamentally differ from depression in other phases of life; however, cognitive deficits are typically more pronounced. The LOD is associated with an increased risk of developing dementia. Imaging studies show reduction in gray matter volume and white matter lesions caused by vascular diseases...

Background. Transcranial magnetic stimulation (TMS) highlighted functional changes in dementia, whereas there are few data in patients with vascular cognitive impairment-no dementia (VCI-ND). Similarly, little is known about the neurophysiological impact of vascular depression (VD) on deterioration of cognitive functions. We test whether depression might affect not only cognition but also specific cortical circuits in subcortical vascular disease. Methods. Sixteen VCI-ND and 11 VD patients, age-matched with 15 controls, underwent a clinical-cognitive, neuroimaging, and TMS assessment...

BACKGROUND AND AIMS: There is increasing evidence linking arterial (mainly aortic) stiffness and type 2 diabetes, a risk factor for arterial stiffness, to cognitive impairment and dementia. However, data on carotid stiffness, which may be especially relevant for cognitive performance, are scarce, and few studies have addressed the interplay between arterial stiffness, type 2 diabetes, and cognitive performance. METHODS: We studied individuals with (n = 197) and without (n = 528) type 2 diabetes, who completed a neuropsychological test battery and underwent applanation tonometry and vascular ultrasound to evaluate aortic (i...

Stroke is the second leading cause of death in the world. Stroke occurs when blood flow stops, and that stoppage results in reduced oxygen supply to neurons in the brain. The occurrence of stroke increases with age, but anyone at any age can suffer from stroke. Recent research has implicated multiple cellular changes in stroke patients, including oxidative stress and mitochondrial dysfunction, inflammatory responses, and changes in mRNA and proteins. Recent research has also revealed that stroke is associated with modifiable and non-modifiable risk factors...

Carotid stiffening is considered an important element in the pathogenesis of cerebrovascular diseases. These include stroke as well as vascular dementia and depression. However, results of individual studies evaluating the association between carotid stiffening and incident stroke have been inconsistent. Therefore, we have conducted a systematic review and meta-analysis, showing that carotid stiffening is associated with incident stroke independently of cardiovascular risk factors and aortic stiffness. In addition, carotid stiffening improved stroke risk prediction beyond the Framingham stroke risk factors and aortic stiffness...

Reduction of protein phosphatase-2A (PP2A) activity is a common clinical feature of Alzheimer's disease and vascular dementia. In this study, we observed that chronic brain hypoperfusion induced by bilateral common carotid artery occlusion of rats led to PP2A inactivation based on the increase in tyrosine-307 phosphorylation and leucine-309 demethylation of PP2AC and the depression in PP2ABα. Knockdown of miR-195 using overexpression of its antisense molecule oligonucleotide (pre-AMO-miR-195) delivered by a lentivirus (lenti-pre-AMO-miR-195) increased tyrosine-307 phosphorylation and decreased both PP2ABα expression and leucine-309 methylation; these effects were prevented by the overexpression of miR-195 using lenti-pre-miR-195 and controlled by an increase in methylesterase (PME-1) and a decrease in leucine carboxyl methyltransferase-1...

BACKGROUND: Neuropsychiatric symptoms of subcortical vascular dementia (SVaD) are mainly associated with damage to frontal-subcortical circuits and may be similar to symptoms of behavioral variant frontotemporal dementia (bvFTD). The aim of this study was to determine whether the neuropsychiatric manifestations of the Pittsburgh compound B (PiB)-negative SVaD and bvFTD groups differ. METHODS: We compared the Caregiver-Administered Neuropsychiatry Inventory (CGA-NPI) between 48 patients with PiB(-) SVaD and 31 patients with bvFTD...

Poststroke fatigue (PSF) is frequent and affects patients' quality of life. Medication use was hypothesized as being responsible for PSF. Our objective was to evaluate potential relationships between 6-month PSF and medication use at discharge and 6 months after an ischemic stroke. This study is part of STROKDEM, an ongoing longitudinal cohort study, whose main aim is to determine predictors of poststroke dementia. Patients were included within 72 hours after an ischemic stroke and followed up with standardized evaluations...

BACKGROUND: Behavioural and psychological symptoms of dementia are very common. They represent a main cause of burden and distress in caregivers and can lead to early institutionalization of patients. We aimed to find the most specific behavioural and psychological symptoms of dementia that can strongly affect the caregivers' burden. METHODS: Twenty-seven patients and their caregivers were enrolled in this study. All of the patients were affected by Alzheimer's, vascular, or frontotemporal dementia and were evaluated with the Neuropsychiatric Inventory and Mini-Mental State Examination...
