Aim: The present study aimed to: (i) examine the reliability and validity of the Dementia Assessment Sheet for Community-based Integrated Care System 21-items for classifying patients to the appropriate categories for glycemic targets in older patients; and (ii) develop a short version of the tool and examine its reliability and validity.
Methods: A total of 410 older individuals were recruited for this multicenter cross-sectional study. We classified them into three categories used for determining the glycemic target in older patients in Japan based on cognitive functions and activities of daily living. Exploratory factor analyses were used to select the eight items of the shorter version. The reliability and validity of the assessment tools were assessed using Cronbach's alpha coefficients and receiver operating characteristic analyses, respectively.
Results: The Dementia Assessment Sheet for Community-based Integrated Care System 21-items had three latent factors: cognitive function, instrumental activities of daily living and basic activities of daily living. The Dementia Assessment Sheet for Community-based Integrated Care System 8-items was developed based on each factor load quantity and was confirmed to have a strong correlation with the original version (r = 0.965, P < 0.001). Both tools significantly discriminated older adults belonging to category I from those belonging to category II or III, and category III from category I or II.
Conclusions: Both tools had sufficient internal consistency and validity to classify older patients into the categories for determining the glycemic target in this population based on cognitive and daily functions. Geriatr Gerontol Int 2018; 18: 1458-1462.

Rationale And Objectives: Alzheimer's disease (AD) is the most common pathogenesis of dementia, and mild cognitive impairment (MCI) is considered as the intermediate stage from normal elderly to AD. Early detection of MCI is an essential step for the timely intervention of AD to slow the progression of this disease. Different form previous studies in the whole-brain spontaneous activities, this research aimed to explore the low-frequency amplitude spectrum activities of patients with MCI within the default mode network (DMN), which has been involved in the process of maintaining normal cognitive function.

Background: Delirium is associated with patient prognosis after transcatheter aortic valve implantation (TAVI). However, the prognostic impact of subsyndromal delirium, described as an intermediate stage between delirium and normal cognition, is uncertain. The present study aimed to investigate the prognostic impact of delirium severity in patients undergoing TAVI.

Supplementation with NAD+ precursors, such as nicotinamide riboside (NR), offers a potential therapeutic avenue against neurodegenerative pathologies in aging, Alzheimer's disease, and related dementias. A crossover, double-blind, randomized placebo (PBO) controlled trial was conducted to test the safety and efficacy of 8 weeks' active treatment with NR (1 g/day) on cognition and plasma AD biomarkers in older adults with subjective cognitive decline and mild cognitive impairment.

Introduction: This study aimed to clarify the relationship between anxiety about the possibility of developing dementia (dementia onset anxiety) and subjective memory impairment in frail older individuals who require long-term care and are experiencing declining cognitive function.
Methods: This study included 30 frail older individuals requiring long-term care who completed the Everyday Memory Checklist (EMC), which was simultaneously performed by an occupational therapist (OT). Individuals were divided into two groups: with and without anxiety about dementia onset.

Brain serotonin dysregulation is associated with dementia and neuropsychiatric symptomology. However, the prognostic utility of circulating serotonin levels in detecting features of prodromal dementia including functional decline, cognitive impairment, mild behavioural impairment and brain atrophy remains unclear. In this prospective study of memory clinic subjects followed-up for ≤5 years, dementia-free subjects, classified as having no cognitive impairment or cognitive impairment, no dementia at baseline, underwent annual neuropsychological assessments including Montreal Cognitive Assessment, Global Cognition scores and Clinical Dementia Rating Scale Global Scores (where a ≥ 0.
