BACKGROUND: The known link between auditory perception and cognition is often overlooked when testing for cognition. PURPOSE: To evaluate auditory perception in a group of older adults diagnosed with mild cognitive impairment (MCI). RESEARCH DESIGN: A cross-sectional study of auditory perception. STUDY SAMPLE: Adults with MCI and adults with no documented cognitive issues and matched hearing sensitivity and age. DATA COLLECTION: Auditory perception was evaluated in both groups, assessing for hearing sensitivity, speech in babble (SinB), and temporal resolution...

Alzheimer's disease and related dementias (ADRD) can cause sleep and behavioral problems that are problematic for ADRD patients and their family caregivers. Light therapy has shown promise as a nonpharmacological treatment, and preliminary studies demonstrate that timed light exposure can consolidate and improve nighttime sleep efficiency, increase daytime wakefulness and reduce evening agitation without the adverse effects of pharmacological solutions. Compliance with light treatment and the accurate measurement of light exposures during treatment, however, have presented barriers for the adoption of light therapy for ADRD...

A long history of diabetes mellitus and increasing age are associated with the onset of diabetic neuropathy, a painful and highly disabling complication with a prevalence peaking at 50% among elderly diabetic patients. Acetyl-L-carnitine (ALC) is a molecule derived from the acetylation of carnitine in the mitochondria that has an essential role in energy production. It has recently been proposed as a therapy to improve the symptoms of diabetic neuropathy. ALC is widely distributed in mammalian tissues, including the brain, blood-brain barrier, brain neurons, and astrocytes...

Although harboring the apolipoprotein E4 (APOE4) allele is a well known risk factor in Alzheimer's disease (AD), the mechanism by which it contributes to disease risk remains elusive. To investigate the role of proteolysis of apoE4 as a potential mechanism, we designed and characterized a site-directed cleavage antibody directed at position D151 of the mature form of apoE4 and E3. Characterization of this antibody indicated a high specificity for detecting synthesized recombinant proteins corresponding to the amino acid sequences 1-151 of apoE3 and E4 that would generate the 17 kDa (p17) fragment...

Neuroinflammatory changes have been demonstrated to be an important feature of Alzheimer's disease (AD), however; the exact role of neuroinflammation and its progression during disease is still not well understood. One of the main drivers of the neuroinflammatory process is microglial cells. Positron Emission Tomography allows for the quantification of microglial activation by labelling the Translocator Protein 18kDa (TSPO), which becomes overexpressed upon activation of microglial cells. Several radioligands have been designed to target TSPO and have been studied in-vivo in AD populations...

Animal-assisted therapy sessions have been set up in a protected unit for patients with a dementia-related syndrome. The aim is to measure the effects of animal-assisted therapy on behavioural disorders in daily life and care. The results obtained provided some interesting areas to explore and recommendations with a view to optimising the implementation of such a system.

A study was carried out to look into the effectiveness of play and the ways it can be used in the treatment of Alzheimer's disease. An intervention founded on the principal of a recreational setting, taking into account the choice of objects, the layout of the space and the role of the professional, could present itself as a form of therapeutic mediation adapted to this pathology. This study shows that play helps to reduce the behavioural problems of residents with Alzheimer's disease, and boosted their wellbeing and quality of life...

The terms 'dementia' and 'demented' are frequently used to refer to people with neurodegenerative diseases, such as Alzheimer's disease. Based on the cross-analysis of some observational data (historical, linguistic, legal and medical), it is possible to highlight the risks and the issues related to the terminological choices for patients and health professionals.

We identified the novel PSEN1 pathogenic mutation M84V in 3 patients belonging to a large kindred affected by autosomal dominant Alzheimer's disease (AD). The clinical phenotype was characterized by early onset dementia in 14 affected subjects over 3 generations. Detailed clinical, imaging and genetic assessment was performed. We highlighted the presence of unusual symptoms such as frontal executive syndrome, psychosis and spastic paraparesis in these patients. Spastic paraparesis has been reported in other PSEN1 mutations in adjacent codons, suggesting that the position of the genetic defect may affect the clinical expression, although this phenotype can occur in mutations throughout the whole PSEN1 gene...

In the present study, a novel mutation in exon 7 of presenilin 1 (Leu232Pro) was discovered in a Korean patient with early-onset Alzheimer's disease, who represented memory decline at 37 years of age, followed by impairment in spatial activity and concentrations and personality changes. Imaging analyses with magnetic resonance scan showed diffuse atrophy in the frontoparietal regions. Targeted next generation sequencing and Sanger sequencing identified a heterozygous T to C transition at position 695 (c.695T>C) of in presenilin 1 gene (PSEN1), resulting in a novel missense mutation at codon 232 from leucine to proline (L232P)...

BACKGROUND: Gender differences regarding psychiatric ill-health are well known in the general population. However, not much research is done on people with intellectual disability, and especially not among older people with intellectual disability. METHODS: People with intellectual disability aged 55+ years in 2012 in Sweden were identified through a register containing information on those receiving support and service for this type of disability. The cohort comprised 3609 women and 4327 men with mean age 65 and 64 years, respectively...

BACKGROUND: Comfort may be an appropriate goal in advanced dementia. Longitudinal studies on physician decision-making and discomfort assessed by direct observation are rare, and intravenous rehydration therapy is controversial. METHODS: To assess treatment decisions and discomfort in patients with advanced dementia and pneumonia and to compare by intravenous rehydration therapy, we used data from the observational multicenter Italian End of Life Observatory-Prospective Study On DEmentia patients Care...

BACKGROUND: Dementia is a worldwide health concern, which leads to loss of autonomy. To date no curative treatment is available so focus on modifiable risk factors is of particular interest. Hypertension, particularly midlife high blood pressure, has been associated with an increased risk for cognitive decline and dementia including vascular dementia (Vad) and Alzheimer Disease (AD). In this context, antihypertensive treatments might have a preventive effect. OBJECTIVES: To examine the relationship between antihypertensive therapy and cognitive decline or dementia...

Alzheimer's disease (AD) is the most common form of neurodegenerative dementia in the aged brain. Even though its etiology is unknown, factors such as neuroinflammation, mitochondrial dysfunction, formation of reactive oxygen species (ROS), and impaired insulin signaling may play a role. We used a sporadic AD model in rats generated by intracerebroventricular-streptozotocin (i.c.v.-STZ) injection to test the therapeutic effect of gold nanoparticles (GNPs). We tested the null hypothesis that there would be no difference between the STZ+GNPs group and the STZ group in the analyzed markers...

BACKGROUND: The most common cause of dementia is Alzheimer's disease. The major manifestation of the disease is the cognitive impairment which appears at the onset of the disease. In addition to the cognitive impairment there are behavioral dysfunctions such as apathy, anxiety, depression and sleep disturbances. The treatment for the manifestations of Alzheimer is currently pharmacological and behavioral. One of the newest behavioral treatments for Alzheimer is the multi-sensory treatment using the Snoezelen room...

Conditions that cause cognitive impairment and behavioural and personality changes, such as Alzheimer's disease (AD) and related dementia, have global impact across cultures. However, the experience of dementia care can vary between individuals, families, formal caregivers, and social groups from various cultures. Self-reported measures, caregiving stress models, and conceptual theories have been developed to address the physical, financial, psychological, and social factors associated with the experience of dementia care...

There is growing support that cerebrovascular reactivity (CVR) in response to a vasodilatory challenge, also defined as the cerebrovascular reserve, is reduced in Alzheimer's disease dementia. However, this is less clear in patients with mild cognitive impairment (MCI). The current standard analysis may not reflect subtle abnormalities in CVR. In this study, we aimed to investigate vasodilatory-induced changes in the topology of the cerebral blood flow correlation (CBFcorr) network to study possible network-related CVR abnormalities in MCI...
