Subcortical ischemic vascular dementia (SIVD) caused by chronic cerebral hypoperfusion exhibits progressive white matter and cognitive impairments. However, its pathogenetic mechanisms are poorly understood. We investigated the role of interleukin-1β (IL-1β) and its receptor IL-1 receptor type 1 (IL-1R1) in an experimental SIVD model generated via right unilateral common carotid arteries occlusion (rUCCAO) in mice. We found that IL-1β expression was elevated in the corpus callosum at the early stages after rUCCAO...

Abnormal reductions in cortical cerebral blood flow (CBF) have been identified in subcortical vascular cognitive impairment (SVCI). However, little is known about the pattern of CBF reduction in relation with the degree of cognitive impairment. CBF measured with three-dimensional (3D) Arterial Spin Labeling (ASL) perfusion magnetic resonance imaging (MRI) helps detect functional changes in subjects with SVCI. We aimed to compare CBF maps in subcortical ischemic vascular disease (SIVD) subjects with and without cognitive impairment and to detect the relationship of the regions of CBF reduction in the brain with the degree of cognitive impairment according to the z-score...

BACKGROUND: Vascular dementia is the second most common cause of dementia affecting over seven million people worldwide, yet there are no licensed treatments. There is an urgent need for a clinical trial in this patient group. Subcortical ischaemic vascular dementia is the most common variant of vascular dementia. This randomised trial will investigate whether use of calcium channel blockade with amlodipine, a commonly used agent, can provide the first evidence-based pharmacological treatment for subcortical ischaemic vascular dementia...

Water disinfection plays a crucial role in water safety but it is also a matter of concern as the use of disinfectants promotes the formation of disinfection by-products (DBPs). Haloacetic acids (HAAs) are one of the major classes of DBPs since they are frequently found in treated water, are ubiquitous, pervasive and have high water solubility, so a great concern emerged about their formation, occurrence and toxicity. Exposure to HAAs is influenced by consumption patterns and diet of individuals thus their bioavailability is an important parameter to the overall toxicity...

Senecavirus A (SV-A), formerly, Seneca Valley virus (SVV), has been detected in swine with vesicular lesions and is thought to be associated with swine idiopathic vesicular disease (SIVD), a vesicular disease syndrome that lacks a defined causative agent. The clinical presentation of SIVD resembles that of other more contagious and economically devastating vesicular diseases, such as foot-and-mouth disease (FMD), swine vesicular disease (SVD), and vesicular stomatitis (VS), that typically require immediate rule out diagnostics to lift restrictions on animal quarantine, movement, and trade...

Rats subjected to bilateral common carotid arteries (CCAs) occlusion or 2-vessel occlusion (2VO) have been used as animal models of subcortical ischemic vascular dementia (SIVD). However, these models possess an inherent limitation in that cerebral blood flow (CBF) drops sharply and substantially after ligation of CCAs without vascular risk factors and causative small vessel changes. We previously reported a novel rat model of 2-vessel gradual occlusion (2VGO) in which ameroid constrictors (ACs) were placed bilaterally in the CCAs of Wistar-Kyoto rats...

BACKGROUND: Body composition measurements provide important information about physical fitness and nutritional status. People with severe intellectual and visual disabilities (SIVD) have an increased risk for altered body composition. Bioelectrical impedance analysis (BIA) has been evidenced as a reliable and non-invasive method to asses body composition in healthy persons and various patient populations; however, currently, there is no feasible method available to determine body composition in people with SIVD...

Subcortical ischemic vascular dementia (SIVD) caused by chronic cerebral hypoperfusion develops with progressive white matter and cognitive impairments, yet no effective therapy is available. We investigated the temporal effects of minocycline on an experimental SIVD exerted by right unilateral common carotid arteries occlusion (rUCCAO). Minocycline treated at the early stage (day 0-3), but not the late stage after rUCCAO (day 4-32) alleviated the white matter and cognitive impairments, and promoted remyelination...

Subcortical ischemic vascular dementia (SIVD) is a main subgroup of vascular dementia related to cerebral small vessel disease. Risk factors for SIVD include hypertension, ageing, and diabetes mellitus, but the specific contribution of each factor to the development of cerebral small vessel disease remains obscure. This is mainly because SIVD in the elderly might be affected by many factors related to the ageing process. Hereditary cerebral small vessel diseases, including cerebral autosomal-dominant or autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL or CARASIL) and cerebral amyloid angiopathy, are affected by different pathomechanisms, but these diseases indicate a clear a role of the cerebral small vessel on subcortical dementia...

BACKGROUND: Glutamatergic deficits are well-established neurochemical findings in Alzheimer's disease (AD) and are thought to underlie both cognitive and behavioral symptoms of the disease. However, it is unclear whether subcortical ischemic vascular dementia (SIVD) and mixed SIVD/AD (MixD) manifest similar changes in the glutamatergic system. OBJECTIVE: To measure the immunoreactivities of NMDA receptor GluN1, GluN2A, and GluN2B subunits in SIVD and MixD. METHODS: Postmortem neocortical tissues from a cohort of well-characterized, longitudinally followed-up patients with SIVD and MixD, together with age-matched controls, were processed for immunoblotting with GluN subunit-specific antibodies...

Resting-state functional magnetic resonance imaging (RS-fMRI) allowed researchers to detect intrinsic brain activity during rest and has been considered an analytical tool for evaluation of dementia. Previously, subcortical ischemic vascular disease (SIVD) has been found decreased amplitude low-frequency fluctuations (ALFF) in a widely frequency range (0.01-0.08Hz) in the bilateral precuneus and increased ALFF values in the bilateral anterior cingulate cortex (ACC), left insula and hippocampus, which showed significant correlations with the cognitive performance...

The N-methyl-d-aspartate glutamate receptor (NMDA-R) plays a central role in learning and memory and has therefore a potential role in the pathophysiology of neuropsychiatric disorders. Recently, we detected NMDA-R autoantibodies in aged healthy volunteers without neuropsychiatric disorders. Since studies showing the involvement of NMDA-R antibodies in mild cognitive impairment and different forms of dementia are rare, we examined NMDA-R antibodies (Abs) in serum of 46 patients with Alzheimer's disease (AD), 26 patients with subcortical ischemic vascular dementia (SIVD), 18 patients with frontotemporal dementia (FTD), 11 patients with Lewy body disease (LBD) and 33 patients with mild cognitive impairment (MCI) and in 21 healthy aged, gender-matched volunteers...
