Inter-method and anatomical correlates of episodic memory tests in the Alzheimer's Disease spectrum.

Episodic memory impairments have been described as initial clinical findings in the Alzheimer's Disease (AD) spectrum, which could be associated with the presence of early hippocampal dysfunction. However, correlates between performances in neuropsychological tests and hippocampal volumes in AD were inconclusive in the literature. Divergent methods to assess episodic memory have been depicted as a major source of heterogeneity across studies.

Neuropsychological and neurophysiological characterization of mild cognitive impairment and Alzheimer's disease in Down syndrome.

Down syndrome (DS) has been considered a unique model for the investigation of Alzheimer's disease (AD) but intermediate stages in the continuum are poorly defined. Considering this, we investigated the neurophysiological (i.e., magnetoencephalography [MEG]) and neuropsychological patterns of mild cognitive impairment (MCI) and AD in middle-aged adults with DS. The sample was composed of four groups: Control-DS (n = 14, mean age 44.64 ± 3.30 years), MCI-DS (n = 14, 51.64 ± 3.95 years), AD-DS (n = 13,...

The Role of Free and Cued Selective Reminding Test in Predicting 18FFlorbetaben PET Results in Mild Cognitive Impairment and Mild Dementia.

Free and Cued Selective Reminding Test (FCSRT) is a reliable cognitive marker for Alzheimer's disease (AD), and the identification of neuropsychological tests sensitive to the early signs of AD pathology is crucial both in research and clinical practice.

Atypical Repetition in Daily Conversation on Different Days for Detecting Alzheimer Disease: Evaluation of Phone-Call Data From Regular Monitoring Service.

Identifying signs of Alzheimer disease (AD) through longitudinal and passive monitoring techniques has become increasingly important. Previous studies have succeeded in quantifying language dysfunctions and identifying AD from speech data collected during neuropsychological tests. However, whether and how we can quantify language dysfunction in daily conversation remains unexplored.

Eye Movements in Neuropsychological Tasks.

This chapter reviews how recording and analysis of eye movements have been applied to understanding cognitive functioning in patients with neurological disease. Measures derived from the performance of instructed eye movement tests such as the anti-saccade and memory-guided saccade tasks have been shown to be associated with cognitive test performance and the early stages of neurodegenerative disorders including Alzheimer's and Parkinson's disease. Other researchers have taken an ecological approach and rec...

Neurocognitive Assessment and Retinal Thickness Alterations in Alzheimer Disease: Is There a Correlation?

The relation of retinal thickness to neuropsychological indexes of cognitive impairment in patients with Alzheimer disease (AD) remains an area of investigation. The scope of this investigation was to compare volume and thickness changes of neuronal retinal layers in subjects with AD with those of age-matched healthy controls and to estimate the relation between cognitive functioning evaluated by neuropsychological assessment and thickness changes of the retina.

Alzheimer's/Vascular Spectrum Dementia: Classification in Addition to Diagnosis.

Alzheimer's disease (AD) and vascular dementia (VaD) are the two most common types of dementia. Although the combination of these disorders, called 'mixed' dementia, is recognized, the prevailing clinical and research perspective continues to consider AD and VaD as independent disorders. A review of recent neuropathological and neuropsychological literature reveals that these two disorders frequently co-occur and so-called 'pure' AD or VaD is comparatively rare. In addition, recent research shows that vascu...

Interaction between APOE4 and herpes simplex virus type 1 in Alzheimer's disease.

Numerous results suggest the implication of infectious agents in the onset of Alzheimer's disease (AD).

Three-year changes of cortical F-FDG in amnestic vs. non-amnestic sporadic early-onset Alzheimer's disease.

To examine and compare longitudinal changes of cortical glucose metabolism in amnestic and non-amnestic sporadic forms of early-onset Alzheimer's disease and assess potential associations with neuropsychological performance over a 3-year period time.

Complexity in neuropsychological assessments of cognitive impairment: A network analysis approach.

In a neuropsychological assessment, each test aims at measuring a single cognitive function. However, test performance depends on an interconnected system of cognitive functions and individual characteristics. For a better understanding of cognitive deficits, it is fundamental to recognize this complexity and study the relationships between test performances. This study aims to evaluate complexity in neuropsychological assessment through network analysis (NA) in 165 healthy older adults, 191 patients with A...

miR-16-5p and miR-19b-3p prevent amyloid β-induced injury by targeting BACE1 in SH-SY5Y cells.

Alzheimer's disease is the most common neurodegenerative disease, characterized by accumulation of amyloid β peptides. MicroRNAs have been identified as significant regulators and therapeutic targets of Alzheimer's disease. However, the roles of miR-16-5p and miR-19b-3p and their mechanisms in Alzheimer's disease progression remain largely unknown.

Cerebrospinal fluid amyloid levels are associated with delayed memory retention in cognitively normal biomarker-negative older adults.

Alzheimer's disease is defined by abnormal levels of amyloid and tau biomarkers. Even cognitively normal older adults with clinically relevant amyloid and tau levels perform worse on memory tests. However, it is unclear if the relationship between biomarker level and memory extends below clinical thresholds. We hypothesized that even subclinical biomarker levels are associated with memory when measured with neuropsychological tests designed to detect dysfunction in preclinical disease states. In a group of ...

Case study of an Iranian-American neuropsychological assessment in the surgical setting: role of language and tests.

There is a growing need to conduct a neuropsychological assessment with bilingual Middle Eastern populations, particularly those who speak the Persian language (Farsi). Although validated neuropsychological and language tests have emerged in Iran, there remains a shortage of appropriate psychometric tests in the U.S. that have been validated for use with the Iranian-American population. This often leads to an assortment of using U.S. tests in English, U.S. tests translated into Farsi, and Iranian tests in F...

A pilot study of exenatide actions in Alzheimer's disease.

Strong preclinical evidence suggests that exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist used for treating type 2 diabetes, is neuroprotective and disease- modifying in Alzheimer's disease (AD).

"Like He's a Kid": Relationality, Family Caregiving, and Alzheimer's Disease.

Spousal caregivers draw upon understandings of shifting relationality to maintain a familial understanding of their spouse with Alzheimer's disease. Working through what it means to think of an adult with Alzheimer's disease "like a child," I trace how spouses negotiate their shifting relationships across the course of Alzheimer's. While regarding adults as childlike can be perceived as dehumanizing infantilization, for families living with Alzheimer's disease, conceiving of one's spouse as like a child can...

Cognitive Decline and Alzheimer's Disease in Old Age: A Sex-Specific "Cytokinome Signature".

Elevated peripheral levels of different cytokines and chemokines in subjects with Alzheimer's disease (AD), as compared with healthy controls (HC), have emphasized the role of inflammation in such a disease. Considering the cross-talking between the central nervous system and the periphery, the inflammatory analytes may provide utility as biomarkers to identify AD at earlier stages.

Real-world evidence in Alzheimer's disease: The ROADMAP Data Cube.

The ROADMAP project aimed to provide an integrated overview of European real-world data on Alzheimer's disease (AD) across the disease spectrum.

Low-Frequency Repetitive Transcranial Magnetic Stimulation of the Right Dorsolateral Prefrontal Cortex Enhances Recognition Memory in Alzheimer's Disease.

Balance and Mobility Performance Along the Alzheimer's Disease Spectrum.

Balance impairments are common in patients with Alzheimer's disease (AD) dementia.

Changes in visual function and retinal structure in the progression of Alzheimer's disease.

Alzheimer's Disease (AD) can cause degeneration in the retina and optic nerve either directly, as a result of amyloid beta deposits, or secondarily, as a result of the degradation of the visual cortex. These effects raise the possibility that tracking ophthalmologic changes in the retina can be used to assess neurodegeneration in AD. This study aimed to detect retinal changes and associated functional changes in three groups of patients consisting of AD patients with mild disease, AD patients with moderate ...

Genome-wide association analysis of dementia and its clinical endophenotypes reveal novel loci associated with Alzheimer's disease and three causality networks: The GR@ACE project.

Large variability among Alzheimer's disease (AD) cases might impact genetic discoveries and complicate dissection of underlying biological pathways.

Interferons: a molecular switch between damage and repair in ageing and Alzheimer's disease.

Alzheimer's disease was first described over 100 years ago, yet it remains incurable and affects 44 million people worldwide. Traditionally, research has largely focused on the amyloid cascade hypothesis, but interest in the importance of inflammation in the progression of the disease has recently been increasing. Interferons, a large family of cytokines that trigger the immune system, are believed to play a crucial role in the pathology of Alzheimer's disease. This review focuses on how interferons affect ...

Association between alcohol consumption and Alzheimer's disease: A Mendelian randomization study.

Observational studies have suggested that light-to-moderate alcohol consumption decreases the risk of Alzheimer's disease, but it is unclear if this association is causal.

Adverse Vascular Risk Relates to Cerebrospinal Fluid Biomarker Evidence of Axonal Injury in the Presence of Alzheimer's Disease Pathology.
