It is accepted that a lumbar puncture (LP) and cerebrospinal fluid (CSF) biomarker analysis support the routine diagnostic work-up for the differential diagnosis of dementia due to Alzheimer's disease (AD) within certain patient cohorts1. These tests, which measure CSF protein concentrations of amyloid-β42 (Aβ42), total tau (t-tau) and phospho tau (p-tau), were recently validated, accredited and made available clinically for the first time in Ireland. A working group, comprising Irish clinical and scientific researchers, met to review a) the validation results; b) international consensus opinions, and c) research and clinical evidence as to the clinical utility of CSF biomarker analysis for AD dementia diagnosis...

OBJECTIVE: Elevated blood pressure is a significant public health concern, particularly given its association with cardiovascular disease risk, including stroke. Caring for a loved one with Alzheimer's disease has been associated with physical health morbidity, including higher blood pressure. Engagement in adaptive coping strategies may help prevent blood pressure elevation in this population. This 5-year longitudinal study examined whether greater participation in pleasant leisure activities was associated with reduced blood pressure in caregivers...

PURPOSE: To suppress partial volume effect (PVE) in brain PET, there have been many algorithms proposed. However, each methodology has different property due to its assumption and algorithms. Our aim of this study was to investigate the difference among partial volume correction (PVC) method for tau and amyloid PET study. METHODS: We investigated two of the most commonly used PVC methods, Müller-Gärtner (MG) and geometric transfer matrix (GTM) and also other three methods for clinical tau and amyloid PET imaging...

BACKGROUND: Alzheimer's disease (AD) has high a prevalence rate, high medical costs, and care difficulties, and has become a serious social and economic problem in our aging society. So far, there has not been a reliable and objective diagnostic criteria for AD found. In recent years, there have been many domestic and foreign studies on the biological markers of cerebrospinal fluid in the patients with AD, and high levels of the T-tau, P-tau found in cerebrospinal fluid (CSF) is at this point an indisputable fact...

Background and Objectives: Historically, research, practice, and policy on Alzheimer's family care has been largely focused on dyadic relationships and the experience of burden and stress, often failing to capture the complex caring dynamics as they unfold over time. This study sought to develop a more nuanced understanding of how people with Alzheimer's disease (AD) and their families are affected by the disease and how they respond to the challenges AD poses. Research Design and Methods: Using constructivist grounded theory, the study explored the experiences of living with AD for native Spanish families residing in Navarra...

Katie L Stewart, Sheena E Radford
Aggregation of the amyloid-β (Aβ) peptide is strongly correlated with Alzheimer's disease (AD). Recent research has improved our understanding of the kinetics of amyloid fibril assembly and revealed new details regarding different stages in plaque formation. Presently, interest is turning toward studying this process in a holistic context, focusing on cellular components which interact with the Aβ peptide at various junctures during aggregation, from monomer to cross-β amyloid fibrils. However, even in isolation, a multitude of factors including protein purity, pH, salt content, and agitation affect Aβ fibril formation and deposition, often producing complicated and conflicting results...

This work describes a novel approach to produce an antibody-like biomimetic material. It includes preparing composite imprinted material never presented before, with highly conductive support nanostructures and assembling a high conductivity polymeric layer at low temperature. Overall, such highly conductive material may enhance the final features of electrically-based devices. Acetylcholine (ACh) was selected as target analyte, a neurotransmitter of importance in Alzheimer's disease. Potentiometric transduction was preferred, allowing quick responses and future adaptation to point-of-care requirements...

Lithium has been marketed in the United States of America since the 1970s as a treatment for bipolar disorder. More recently, studies have shown that lithium can improve cognitive decline associated with Alzheimer's disease (AD). However, the current United States Food and Drug Administration-approved lithium pharmaceutics (carbonate and citrate chemical forms) have a narrow therapeutic window and unstable pharmacokinetics that, without careful monitoring, can cause serious adverse effects. Here, we investigated the safety profile, pharmacokinetics, and therapeutic efficacy of LISPRO (ionic co-crystal of lithium salicylate and l-proline), lithium salicylate, and lithium carbonate (Li2CO3)...

AIMS: Alzheimer's disease (AD), a progressive development dementia, is increasingly impacting patients' living conditions worldwide. Despite medical care and funding support, there are still no highly individualized drugs and practical strategies for clinical prevention and treatment. Developmentally regulated brain protein (abbreviated as Drebrin or Dbn, also known as Dbn1 in mouse) exists in neurons, especially in dendrites, and is an actin-binding protein that modulates synaptic morphology and long-term memory...

Given the sheer number of drugs (over 20!) available for treatment of seizures, epilepsy can be considered one of the most successful areas in pharmaceutical development and especially for neuroscience. However, despite the large number of drug treatment options available for managing patients with epilepsy, there remains considerable unmet need. For example, the overall impact on seizure control has not been substantial with approximately 30% of patients remaining refractory or their seizures not adequately controlled...

In France, few studies have examined home care when it comes to ageing support and even fewer have considered alcohol misuse in this context. The studies also show that being old and having alcohol use disorders are two unfavourable conditions for receiving help, whereas for the Alzheimer's disease, there is a clear need for optimal care. In this article, we study professional home caregiver's perceptions of their job along with their difficulties and satisfactions in supporting older people with Alzheimer's disease or alcohol misuse...

BACKGROUND: Mild cognitive impairment (MCI) often represents the clinical manifestation of cognitive deterioration preceding Alzheimer's disease (AD). Currently, there are no reliable approaches for an objective evaluation of the risk of developing AD in MCI patients. OBJECTIVE: The aim of this study was to verify whether the Framingham cardiovascular risk profile (FCRP) could be useful to identify patients at the highest risk of conversion from MCI to AD. METHODS: Patients with amnestic MCI (aMCI) were carefully investigated to assess their vascular risk profile...

In rodents, fragmented and low levels of maternal care have been implicated in age-related cognitive decline and the incidence and progression of Alzheimer's pathology. In contrast, enhancing early postnatal maternal care has been associated with improved cognitive function later in life. Here we examined whether early postnatal handling of mouse pups from postnatal days 2-9 enhanced maternal care and whether this affected cognition and Alzheimer pathology at 5 and 11months of age in the APPswe/PS1dE9 mouse model for Alzheimer's disease...

BACKGROUND AND PURPOSE: Arterial spin-labeling MR imaging has been recently developed as a noninvasive technique with magnetically labeled arterial blood water as an endogenous contrast medium for the evaluation of CBF. Our aim was to compare arterial spin-labeling MR imaging and SPECT in the visual assessment of CBF in patients with Alzheimer disease. MATERIALS AND METHODS: In 33 patients with Alzheimer disease or mild cognitive impairment due to Alzheimer disease, CBF images were obtained by using both arterial spin-labeling-MR imaging with a postlabeling delay of 1...
