Elevation of blood triglycerides, primarily as triglyceride-rich lipoproteins (TGRL), has been linked to cerebrovascular inflammation, vascular dementia, and Alzheimer's disease (AD). Brain microvascular endothelial cells and astrocytes, two cell components of the neurovascular unit, participate in controlling blood-brain barrier (BBB) permeability and regulating neurovascular unit homeostasis. Our studies showed that infusion of high physiological concentrations of TGRL lipolysis products (TGRL + lipoprotein lipase) activate and injure brain endothelial cells and transiently increases the BBB transfer coefficient (Ki=permeability x surface area/volume) in vivo...

BACKGROUND: A substantial literature has reported that stress negatively impacts on cognitive processes. As dementia caregiving can be stressful, it has been hypothesized that the challenges of dementia care may increase caregivers' own vulnerability to cognitive decline. Prefrontal processes are thought to be most vulnerable to stress; however, few studies have examined whether greater caregiver stress predicts poorer executive dysfunction, and no previous research has considered potential moderators of this relationship...

AIM: The present study was designed to investigate the potential of Cyclosporine (CsA) and Tacrolimus, the inhibitors of calcineurin (CaN) in cognitive deficits of mice. METHODS: Streptozotocin [STZ, 3mg/kg, injected intracerebroventricular (i.c.v.)] was used to induce memory deficits in NIH mice, while aged mice separately taken served as a natural model of dementia. Morris water maze (MWM) test was employed to evaluate learning and memory of the animals. A battery of biochemical and histopathological studies was also performed...

Alzheimer's disease (AD) is a severe, chronic and progressive neurodegenerative disease associated with memory and cognition impairment ultimately leading to death. It is the commonest reason of dementia in elderly populations mostly affecting beyond the age of 65. The pathogenesis is indicated by accumulation of the amyloid-beta (Aβ) plaques and neurofibrillary tangles (NFT) in brain tissues and hyperphosphorylation of tau protein in neurons. The main cause is considered to be the formation of reactive oxygen species (ROS) due to oxidative stress...

AIM: The objectives of this study were to illuminate how family members of persons with dementia describe their own experiences, before and after placing the relative in a nursing home. Background In the western world and with a growing population of older people, the number of persons with dementia increase. Family members often become carers in their own homes creating stressful and exhausting situation that eventually leads to re-locating the person to a 6 nursing home. This may lead to troubled conscience among family members...

Alzheimer's disease (AD) and behavioral variant of Frontotemporal Dementia (bvFTD) are characterized respectively by atrophy in the medial temporal lobe with memory loss and prefrontal and anterior temporal degeneration with dysexecutive syndrome. In this study, we hypothesized that specific gait patterns are induced by either frontal or temporal degeneration. To test this hypothesis, we studied the gait pattern in bvFTD (23) and AD (22) patients in single and dual task ("motor" and "cognitive") conditions...

Vascular dementia (VaD) is the second leading type of dementia after Alzheimer's disease plaguing the aging population. Acupuncture has served as alternative and complementary medicine in the world for a long time and its use for VaD is based on a large body of preclinical and clinical researches. The mechanisms that underlie the protective effects of acupuncture are slowly beginning to be understood. Acupuncture influences multiple aspects of the pathological process of VaD. It improves cognitive function through protecting cerebral neurons from oxidative stress, apoptosis, and neuroinflammation, regulating glucose metabolism and neurotransmitters...

The pathogenesis of Alzheimer's disease (AD) is well documented to involve mitochondrial dysfunction which causes subsequent oxidative stress and energy metabolic failure in hippocampus. Methylene blue (MB) has been implicated to be neuroprotective in a variety of neurodegenerative diseases by restoring mitochondrial function. The present work was to examine if MB was able to improve streptozotocin (STZ)-induced Alzheimer's type dementia in a rat model by attenuating mitochondrial dysfunction-derived oxidative stress and ATP synthesis decline...

An unknown number of mentally ill elders in the U.S. receive care in assisted living [AL], along with persons facing physical or cognitive challenges. While dementia is familiar in AL, our data indicate that neither staff nor residents are prepared to work or live with the mentally ill. Challenges are created for professionals, since these residents bring diverse needs. Daily inter-resident interactions are also disrupted or stressful. Qualitative data describe the impacts on quality of resident life as well as care and management dilemmas identified within five assisted living settings having varying presence of mental illness among residents...

OBJECTIVE: Inappropriate sexual behaviors (ISBs) represent challenging and stressful manifestations of dementia and are highly burdening for patients, families, and healthcare providers. Nevertheless, ISBs have so far attracted limited clinical and scientific interest compared with other neuropsychiatric symptoms occurring in dementing illnesses. The authors aimed to systematically investigate the prevalence and characteristics of ISBs in a population of patients with dementia attending a memory clinic...

Older people are particularly exposed to stressful events, known to activate the hypothalamus-pituitary-adrenal axis resulting in increased cortisol levels. High cortisol has been associated with deleterious effects on cognition. We hypothesized that stressful life events could increase cortisol secretion leading to cognitive impairment. A cross-sectional analysis was conducted using data from Colaus/PsyColaus, a longitudinal population-based study among Lausanne residents. Salivary cortisol samples were obtained from 796 nondemented subjects aged at least 65...

Listening to music may be thought of as noninvasive and nonpharmacological, but music should be considered a drug therapy. Music exposure has measurable neurobiological effects that are linked to systems regulating reward, motivation, and pleasure; stress and arousal; and immunity. Functional neuroimaging and lesion studies demonstrate that music-evoked emotions are associated with modulation of linked limbic and paralimbic brain regions. Some of these regions are involved in reward, motivation, and pleasure, and there are additional projections to brain structures regulating autonomic, emotional, and cognitive function...

PURPOSE: Most health outcome measures for chronic diseases do not incorporate specific health goals of patients and caregivers. To elicit patient-centered goals for dementia care, we conducted a qualitative study using focus groups of people with early-stage dementia and dementia caregivers. METHODS: We conducted 5 focus groups with 43 participants (7 with early-stage dementia and 36 caregivers); 15 participants were Spanish-speaking. Verbatim transcriptions were independently analyzed line-by-line by two coders using both deductive and inductive approaches...

As the physiological impact of chronic stress is difficult to study in humans, naturalistic stressors are invaluable sources of information in this area. This review systematically evaluates the research literature examining biomarkers of chronic stress, including neurocognition, in informal dementia caregivers. We identified 151 papers for inclusion in the final review, including papers examining differences between caregivers and controls as well as interventions aimed at counteracting the biological burden of chronic caregiving stress...

Chronic cerebral hypoperfusion (CCH) has been recognized as an important cause of both vascular dementia and Alzheimer's disease (AD), the two most prominent neurodegenerative diseases causing memory impairment in the elderly. However, an effective therapy for CCH-induced memory impairment has not yet been established. Grape seed polyphenol extract (GSPE) has powerful antioxidant properties and protects neurons and glia during ischemic injury, but its potential use in the prevention of CCH-induced memory impairment has not yet been investigated...

As individuals live longer with HIV, this "graying of the HIV epidemic" has introduced a new set of challenges including a growing number of age and inflammation-related diseases such as cardiovascular disease, type II diabetes, cancer, and dementia. The biological underpinnings of these complex and co-morbid diseases are not fully understood and become very difficult to disentangle in the context of HIV and aging. In the current review we examine the contributions and interactions of HIV, stress, and cognitive impairment and query the extent to which inflammation is the linchpin in these dynamic interactions...

Since 1978, two systematic evidence-based reviews of the available data on religiosity and mental health in the field of psychiatry have been done. More than 70 % found a relationship between level of religious/spiritual involvement and less mental disorder (positive), some found mixed results (positive and negative), and only about 5 % reported more mental disorder (negative), as was originally suggested by Sigmund Freud. There is good evidence that religious involvement is correlated with better mental health in the areas of depression, substance abuse, and suicide; some evidence in stress-related disorders and dementia; insufficient evidence in bipolar disorder and schizophrenia, and no data in many other mental disorders...

Alzheimer's disease (AD) is the major cause of dementia and no preventive or effective treatment has been established to date. The etiology of AD is poorly understood, but genetic and environmental factors seem to play a role in its onset and progression. In particular, factors affecting the one-carbon metabolism (OCM) are thought to be important and elevated homocysteine (Hcy) levels, indicating impaired OCM, have been associated with AD. We aimed at evaluating the role of polymorphisms of key OCM enzymes in the etiology of AD, particularly when intakes of relevant B-vitamins are inadequate...

Nonsense-mediated RNA decay (NMD) selectively degrades mutated and aberrantly processed transcripts that contain premature termination codons (PTC). Cellular NMD activity is typically assessed using exogenous PTC-containing reporters. We overcame some inherently problematic aspects of assaying endogenous targets and developed a broadly applicable strategy to reliably and easily monitor changes in cellular NMD activity. Our new method was genetically validated for distinguishing NMD regulation from transcriptional control and alternative splicing regulation, and unexpectedly disclosed different sensitivity of NMD targets to NMD inhibition...
