Background: Dynamic cerebral autoregulation (dCA) remains intact in both ageing and dementia, but studies of neurovascular coupling (NVC) have produced mixed findings. Objective: We investigated the effects of task-activation on dCA in healthy older adults (HOA), and patients with mild cognitive impairment (MCI) and Alzheimer’s Disease (AD). Methods: Resting and task-activated data from thirty HOA, twenty-two MCI, an Read More

Background: Alzheimer's disease (AD) is a chronic neurodegenerative disease that has been characterized by progressive development of long onset early disease with complicated etiology and may cause memory loss, cognitive impairment, and behavioral changes. Physical exercise may play a preventive role in AD. In the present study, we investigated the impact of longer-term physical exercise on the finger tapping of A Read More

Background: Alzheimer’s Disease (AD) is still a great global challenge and agents with various mechanisms represent a promising therapeutic opportunity. Theracurmin, a very highly absorbable curcumin formulation, was shown to improve memory and attention in non-demented people. Objective: The aim of the study was to investigate the effect of Theracurmin on disease course in elderly patients with mild cognitive im Read More

Objective: The objective of this study is to examine the association of olfactory function and genetic predisposition of Alzheimer’s disease (AD) with cognitive performance in adults. Methods: A total of 2049 Chinese adults from Rugao Longevity and Ageing Study (RuLAS, n=1460, mean age 78 years) and Central China Cohort (CCC, n=589, mean age 48 years) were included in this study. A standard interview-based survey, clinic Read More

Background: Blink rate (BR) is considered a marker of dopaminergic activity in humans. BR is increased in patients with Mild Cognitive Impairment (MCI), but no study has yet investigated whether BR changes with the progression of cognitive decline from MCI to Alzheimer’s disease (AD) and whether BR abnormalities are present in subjects with Subjective Cognitive Decline (SCD). Objective: The aim of our study was to assess Read More

Background: The aim of this study was to establish the validity and reliability of the Computerized Brief Cognitive Screening Test (CBCog) for early detection of cognitive impairment. Methods: One hundred and sixty participants, including community-dwelling and out-patient volunteers (both men and women) aged ≥ 65 years, were enrolled in the cross section study. All participants were screened using the CBCog and Mini-Me Read More

Background: Although clusterin-a protein involved in lipid metabolism, amyloid beta clearance, and myelination-has been linked to gray matter atrophy within samples of older adults at risk for Alzheimer’s disease, research exploring associations with white matter (WM) micro- and macro- structural markers are largely limited. Objective: The current study explored associations between serum clusterin protein levels and W Read More

Introduction: This study aimed to build the supervised learning model to predict the state of cognitive impairment, Alzheimer’s Disease (AD) and cognitive domains including memory, language, action, and visuospatial based on Digital Clock Drawing Test (dCDT) precisely. Methods: 207 normal controls, 242 Mild Cognitive Impairment (MCI) patients, 87 dementia patients, including 53 AD patients, were selected from Shanghai To Read More

Background: The development of cholinergic deficit is considered an early sign of a number of pathological conditions, including Alzheimer’s disease. Cholinergic dysfunction underlies cognitive decline associated with both normal aging and Alzheimer’s disease. Objective: Here, we studied a possible mechanism of functional impairment of cholinergic neurons using an olfactory bulbectomy model. Methods: Male mice were s Read More
