OBJECTIVE: Cognitive fluctuations (CFs) occur commonly in dementia of all types. While it is generally accepted that CFs can affect the clinical rating of dementia severity and neuropsychological performance, little is known about their impact on patients' activities of daily living (ADLs) and quality of life (QOL). Our study aims to explore the impact of CFs on ADLs and QOL among institutionalized patients with dementia. METHODS: The present study examined the nature and frequency of CFs in 55 institutionalized dementia patients...

With an increasing focus on biomarkers in dementia research, illustrating the role of neuropsychological assessment in detecting mild cognitive impairment (MCI) and Alzheimer's dementia (AD) is important. This systematic review and meta-analysis, conducted in accordance with PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) standards, summarizes the sensitivity and specificity of memory measures in individuals with MCI and AD. Both meta-analytic and qualitative examination of AD versus healthy control (HC) studies (n = 47) revealed generally high sensitivity and specificity (≥ 80% for AD comparisons) for measures of immediate (sensitivity = 87%, specificity = 88%) and delayed memory (sensitivity = 89%, specificity = 89%), especially those involving word-list recall...

BACKGROUND: It has been suggested that men and women with Alzheimer's disease (AD) at comparable levels of global cognitive impairment perform differently on neuropsychological measures. Such differences may have practical implications for designing cognitive interventions that address symptoms of dementia. METHODS: We compared men (n = 86) and women (n = 96) with AD on tests of immediate and delayed prose memory, verbal fluency, semantic fluency, semantic memory, and confrontation naming...

OBJECTIVES: Cross-sectional and longitudinal evidence from largely non-Hispanic White cohorts suggests that positive psychosocial factors, particularly self-efficacy and social support, may protect against late-life cognitive decline. Identifying potentially protective factors in racial/ethnic minority elders is of high importance due to their increased risk of Alzheimer's disease. The overall goal of this study was to characterize cross-sectional associations between positive psychosocial factors and cognitive domains among Black, Hispanic, and White older adults...

BACKGROUND: Mild cognitive impairment in Parkinson's disease (PD-MCI) is a common clinical condition. Understanding its pathology and clinical features is important for early intervention before the onset of dementia. In the past, variable definitions and differences in neuropsychological batteries generated divergent results of the affected cognitive patterns. MAIN BODY: The introduction of PD-MCI criteria by the Movement Disorders Society (MDS) Task Force provides a more uniform system for defining and measuring PD-MCI and may improve the validity of future research...

Vascular cognitive impairment and dementia (VCID) is a major public health concern because of the increased incidence of vascular disease in the aging population and the impact of vascular disease on Alzheimer's disease. VCID is a heterogeneous group of diseases for which there are no proven treatments. Biomarkers can be used to select more homogeneous populations. Small vessel disease is the most prevalent form of VCID and is the optimal form for treatment trials because there is a progressive course with characteristic pathological changes...

OBJECTIVES: Slow gait has been shown to be a good predictor of declining cognitive function in healthy older adults. Motoric cognitive risk (MCR) syndrome is a new construct incorporating slow gait and subjective cognitive complaints in individuals without dementia who have preserved activities of daily living. This analysis investigated the prevalence of MCR and factors associated with MCR in a nationally representative population. In addition, cross-sectional associations between MCR and cognitive domains, an relationship yet to be fully elucidated in literature, was investigated...

Until now, hypometabolic patterns and their correlations with neuropsychological performance have not been assessed as a function of the various presentations of sporadic early-onset Alzheimer's disease (EOAD). Here, we processed and analyzed the patients' metabolic maps at the vertex and voxel levels by using a nonparametric, permutation method that also regressed out the effects of cortical thickness and gray matter volume, respectively. The hypometabolism patterns in several areas of the brain were significantly correlated with the clinical manifestations...

Orientation to time, date, and place is commonly utilized in clinical settings to aid in diagnosis, staging, and monitoring of Alzheimer's disease (AD). This study aimed to identify the cerebral metabolic correlates of orientation in patients with AD, and the degree to which regions associated with orientation overlap with memory-related structures. Eighty-five patients with a diagnosis of probable AD underwent fluorodeoxyglucose positron emission tomography (FDG-PET) and neuropsychological testing. Orientation items from the Dementia Rating Scale and recognition performance from the Consortium to Establish a Registry for AD (CERAD) Word List Learning test were correlated with cerebral glucose metabolism...
