Regional hyperperfusion in older adults with objectively-defined subtle cognitive decline [PDF]

open access: yesJournal of Cerebral Blood Flow and Metabolism, 2021
Although cerebral blood flow (CBF) alterations are associated with Alzheimer’s disease (AD), CBF patterns across prodromal stages of AD remain unclear. Therefore, we investigated patterns of regional CBF in 162 Alzheimer’s Disease Neuroimaging Initiative participants characterized as cognitively unimpaired (CU; n = 80), objectively-defined subtle ...

Meaningful cognitive decline is uncommon in virally suppressed HIV, but sustained impairment, subtle decline and abnormal cognitive aging are notResearch in context

open access: yesEClinicalMedicine, 2023
Summary: Background: High antiretroviral therapy (ART) coverage and viral suppression among people with HIV (PWH) in Australia provide a unique context to study individual cognitive trajectories, cognitive aging and factors associated with longitudinal ...

Using Neuropsychological Process Scores to Identify Subtle Cognitive Decline and Predict Progression to Mild Cognitive Impairment [PDF]

open access: yesJournal of Alzheimer's Disease, 2018
Background: We previously operationally-defined subtle cognitive decline (SCD) in preclinical Alzheimer’s disease (AD) using total scores on neuropsychological (NP) tests. NP process scores (i.e., provide information about how a total NP score was achieved) may be a useful tool for identifying early cognitive ...

Elevated plasma neurofilament light predicts a faster rate of cognitive decline over 5 years in participants with objectively‐defined subtle cognitive decline and MCI [PDF]

open access: yesAlzheimer's and Dementia, 2021
AbstractIntroductionNeurofilament light (NFL) reflects neuroaxonal damage and is implicated in mild cognitive impairment (MCI) and Alzheimer's disease (AD). Little is known about NFL in pre‐MCI stages, such as in individuals with objectively‐defined subtle cognitive decline (Obj‐SCD).MethodsTwo hundred ninety‐four participants from the Alzheimer's ...

Personality-Related Determinants of Subtle Cognitive Decline in Old Age: A Population-Based Study [PDF]

open access: yesDementia and Geriatric Cognitive Disorders Extra, 2016
Background/Aims: Recent studies of cases with mild cognitive impairment (MCI) suggested that besides Alzheimer disease (AD)-related biomarkers, some personality dimensions are associated with progression to AD.

Using the Montreal cognitive assessment to identify individuals with subtle cognitive decline. [PDF]

open access: yesNeuropsychology, 2022
Dementia is a devastating neurological disease that may be better managed if diagnosed earlier when subclinical neurodegenerative changes are already present, including subtle cognitive decline and mild cognitive impairment. In this study, we used item-level performance on the Montreal Cognitive Assessment (MoCA) to identify individuals with subtle ...

Cognitive Heterogeneity and Risk of Progression in Data-Driven Subtle Cognitive Decline Phenotypes. [PDF]

open access: yesJ Alzheimers Dis, 2022
Background: There is increasing recognition of cognitive and pathological heterogeneity in early-stage Alzheimer’s disease and other dementias. Data-driven approaches have demonstrated cognitive heterogeneity in those with mild cognitive impairment (MCI), but few studies have examined this heterogeneity and its association with progression to MCI ...

Analysis of the relationship between blood pressure variability and subtle cognitive decline in older adults. [PDF]

open access: yesWorld J Psychiatry, 2023
BACKGROUND Blood pressure variability (BPV) has been shown to be related to mild cognitive impairment and Alzheimer's disease in a number of studies. However, the relationship between BPV and subtle cognitive decline (SCD) has received minimal attention in this field of research to date and has rarely been reported. AIM To
