Purpose: The three variants of primary progressive aphasia (PPA) differ in clinical presentation, underlying brain pathology, and clinical course, which stresses the need for early differentiation. However, brief cognitive tests that validly distinguish between all PPA variants are lacking. The Sydney Language Battery (SYDBAT) is a promising…

Background: The CAMDEX-DS is an instrument to diagnose Alzheimer's disease (AD) in Down syndrome consisting of an informant interview and a cognitive test battery (CAMCOG-DS). Measurement properties of the German CAMDEX-DS were investigated. Method: Fifty-five adults with Down syndrome (19-58 years) participated in this observational study.…

This case study describes an art therapy intervention with a client diagnosed with Alzheimer's disease who was coping with grief. The course of fifteen sessions included three phases: body awareness, grief emotions, and grief acceptance. The positive changes parallel ways that art therapy can benefit older adults by promoting communication,…

Misconceptions or inaccurate ideas about Alzheimer's disease (AD) can be found in college students from health-related careers. Refutation texts explicitly introduce inaccurate information, refute it, and introduce alternative, more accurate information. This study examined the role of refutation texts in revising misconceptions about AD in…

Alzheimer's Disease (AD), the most common cause of dementia, is an incurable neurological disease with an unknown cause. Since AD is not only social and health challenge but also an economic and fiscal burden and its prevalence is expected to grow exponentially as world population gets older, in 2012 the World Health Organization (WHO) and…

A set of common-acting iron-responsive 5'untranslated region (5'UTR) motifs can fold into RNA stem loops that appear significant to the biology of cognitive declines of Parkinson's disease dementia (PDD), Lewy body dementia (LDD), and Alzheimer's disease (AD). Neurodegenerative diseases exhibit perturbations of iron homeostasis in defined brain…

Adults with Down syndrome (DS) experience high risk for Alzheimer's disease (AD), but there is variability in the timing of transition from a cognitively stable state to prodromal AD and dementia. The present study examined the association between a modifiable lifestyle factor, employment complexity, and cognitive decline across two time points in…

Case studies are helpful teaching tools that can bring scientific concepts to life. Here, we present a case study related to protein-ligand interactions, amino acids, protein structure, and protein modification. While protein-ligand interaction is a foundational concept within Biochemistry, there are few available case studies that focus on this…

Adults with Down syndrome are at high risk for Alzheimer's disease (AD), with most individuals developing clinical dementia by their late 60s. This increased risk for AD has been attributed, at least in part, to triplication and overexpression of the gene for amyloid precursor protein (APP) on chromosome 21, leading to elevated levels of amyloid…

We have implemented at the University of Málaga (Spain) a new course-based undergraduate research experience (CURE) to involve undergraduate students of Science in a real-world scientific problem. Within the topic "Let's find acetylcholinesterase inhibitors as new drug candidates for the treatment of Alzheimer's", students have been…

Largely inspired from clinical concepts like brain reserve, cognitive reserve, and neural compensation, here we review data showing how neural circuits reorganize in presymptomatic and early symptomatic hAPP mice to maintain memory intact. By informing on molecular alterations and compensatory adaptations which take place in the brain before mice…

Individual differences in cognitive decline during normal aging and Alzheimer's disease (AD) are common, but the molecular mechanisms underlying these distinct outcomes are not fully understood. We utilized a combination of genetic, molecular, and behavioral data from a mouse population designed to model human variation in cognitive outcomes to…

Equating of psychometric scales and tests is frequently required and conducted in educational, behavioral, and clinical research. Construct comparability or equivalence between measuring instruments is a necessary condition for making decisions about linking and equating resulting scores. This article is concerned with a widely applicable method…

Alzheimer's disease (AD) is a threat to the individual and marital integrity of couples as the relationship is called upon to evolve into a caregiver-patient one. In Quebec (Canada), there are currently very few services offered in which these couples can participate together as a couple. In a qualitative multi-case study, five couples had the…

Alzheimer's disease is a progressive neurodegenerative disorder characterized by amyloid plaques, synapse dysfunction, and memory loss. The production and accumulation of A[beta] peptides, a major component of the amyloid plaques, is sensitive to many genetic and environmental factors. Recently, research has focused on the role of oxidative stress…
