Vascular dementia (VaD), the second most common cause of cognitive impairment in the population, is a disease that results from reduction in regional cerebral blood flow and involves oxidative stress and inflammation. Co-ultramicronized PEALut (co-ultra PEALut) is a new compound with beneficial effects, which include anti-inflammatory and antioxidant properties. Recently, co-ultraPEALut has been shown to exhibit neuroprotective effects in models of Parkinson's disease, cerebral ischemia and Alzheimer's disease...

BACKGROUND: Oxidative stress is thought to be a key player in the pathogenesis of neurodegenerative dementia, including Alzheimer's disease (AD). It has been assumed that oxidative stress contributes to the ß-amyloid deposition in cerebral blood vessels. METHODS: In order to prove this hypothesis, we examined the effect of oxidative stress on the processing of amyloid precursor protein (APP) in primary endothelial cells (EC) derived from cerebral cortical tissue of transgenic Tg2576 mice...

The current absence of a disease-modifying treatment for Alzheimer's disease (AD) and vascular cognitive impairment and dementia (VCID) highlights the necessity for investigating the benefits of non-pharmacological approaches such as physical exercise (PE). Although evidence exists to support an association between regular PE and higher scores on cognitive function tests, and a slower rate of cognitive decline, there is no clear consensus on the underlying molecular mechanisms of the advantages of PE. This review seeks to summarize the positive effects of PE in human and animal studies while highlighting the vascular link between these benefits...

Older adults with dementia have higher rates of institutionalization than those without dementia. Desire to institutionalization (DTI) is an important factor influencing the actual institutionalization but is less well studied. This cross-sectional study examines the DTI with the scale of same name developed by Morycz, in 1985, in a sample of 50 caregivers of patients with dementia in a tertiary clinical care setting in a developing country. Caregiver burden associated with personal strain (by factor analyzed Zarit Burden Interview scale), and stress perceived out of caregiving (by Perceived Stress Scale) predicted higher DTI...

Health and social care research on stress in dementia has predominantly considered the stress experienced by family and professional carers. Focus on the person with dementia has frequently laid emphasis on the impact of stress-related behaviour on others and how such behaviour might be 'managed'. This paper describes a qualitative study which gives voice to people with dementia on the subject of stress and responds to the need for a better understanding of stress as it is experienced by people with dementia themselves...

Stimulation as well as inhibition of GABAB (Gamma amino butyric acid) receptors has been reported to show beneficial effects in Alzheimer's disease (AD). Experimental evidences suggest that the use of GABAergic agents could influence learning and memory. The present study was designed to investigate the possible role of GABAB receptors in streptozotocin (STZ)-induced behavioral and biochemical abnormalities in rats. Herein STZ was infused (3mg/kg) bilaterally on alternate days (day 1 and day 3) to produce experimental dementia in rats...

Wandering away from home or facilities is dangerous for patients with dementia and stressful for families and caregivers when those who go missing cannot be located. Up to 60% of Alzheimer's disease patients wander, and up to 50% of those who are not found within 24 hours face serious injury or death. Currently, no effective drug therapies exist to abate wandering, which has multiple causes, but emerging technologies offer a promise of comfort in being able to easily locate a missing loved one. As of 2012, 41 states had enacted Silver Alert programs that broadcast information about missing, vulnerable adults...

Dementia is a chronic or progressive syndrome, characterized by impaired cognitive capacity beyond what could be considered a consequence of normal aging. It affects the memory, thinking process, orientation, comprehension, calculation, learning ability, language, and judgment; although awareness is usually unaffected. Alzheimer's disease (AD) is the most common form of dementia; symptoms include memory loss, difficulty solving problems, disorientation in time and space, among others. The disease was first described in 1906 at a conference in Tubingen, Germany by Alois Alzheimer...

The repressor element 1-silencing transcription (REST) factor is a key regulator of the aging brain's stress response. It is reduced in conditions of stress and Alzheimer's disease (AD), which suggests that increasing REST may be neuroprotective. REST can be measured peripherally in blood plasma. Our study aimed to (1) examine plasma REST levels in relation to clinical and biological markers of neurodegeneration and (2) alter plasma REST levels through a stress-reduction intervention-mindfulness training. In study 1, REST levels were compared across the following four well-characterized groups: healthy elderly (n=65), mild cognitive impairment who remained stable (stable MCI, n=36), MCI who later converted to dementia (converter MCI, n=29) and AD (n=65) from the AddNeuroMed cohort...

The long-term care of cognitively impaired patients with concomitant behavioral problems brings great stress and burdens to family caregivers. The present article describes a family caregiver with multiple chronic diseases who concurrently shouldered primary care responsibilities for her husband, a patient with mild cognitive impairment, problematic behaviors, and medication non-adherence issues. The period of care was between September 23rd and December 29th, 2015. Data on physiological, psychological, and social burdens were collected based on a stress process model for family caregiving...

BACKGROUND: Sirtuins (SIRTs) are NAD(+) dependent lysine deacetylases which are conserved from bacteria to humans and have been associated with longevity and lifespan extension. SIRT1, the best studied mammalian SIRT is involved in many physiological and pathological processes and changes in SIRT1 have been implicated in neurodegenerative disorders, with SIRT1 having a suggested protective role in Parkinson's disease. In this study, we determined the effect of SIRT1 on cell survival and α-synuclein aggregate formation in SH-SY5Y cells following oxidative stress...

Endo-ventricular thrombosis represents a possible clinical complication of stress(takotsubo)-cardiomyopathy (SC). Depressed ventricular systolic ventricular function, localized left ventricular (LV) dyskinesis, but also an increased pro-thrombotic state induced by catecholamine surge may facilitate the occurrence of endovascular thrombosis in SC. SC, however, may also present as right ventricular (RV) dysfunction or even as biventricular ballooning. Ventricular thrombosis may therefore theoretically occur in either ventricles or both...

Alzheimer's disease (AD) is rarely addressed in the context of aging even though there is an overlap in pathology. We previously used a phenotypic screening platform based upon old age-associated brain toxicities to identify the flavonol fisetin as a potential therapeutic for AD and other age-related neurodegenerative diseases. Based on earlier results with fisetin in transgenic AD mice, we hypothesized that fisetin would be effective against brain aging and cognitive dysfunction in rapidly aging SAMP8 mice, a model for sporadic AD and dementia...
