Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is characterized by white matter hyperintensities (WMH) that contribute to executive dysfunction and increased risk of Alzheimer's disease. Cognitive reserve (CR) is the brain's ability to maintain cognitive performance despite pathology. Resting-state functional connectivity ( ...

Introduction: It is unknown whether progressive resistance training (PRT) improves cognitive function in adults with cerebral small vessel disease and mild cognitive impairment (i.e., subcortical vascular cognitive impairment [SVCI]). Methods: We conducted a 12-month randomized trial comparing P ...

Background: Hearing loss is one of the largest potentially modifiable risk factors for dementia and is linked with poor cognitive-motor dual-task performance (e.g., walking while performing a cognitive task). Hearing loss is more prevalent and severe in males, whereas dementia is more prevalent i ...

Background: Common consequences of a stroke include impaired motor and cognitive function, with both being linked to increased falls and frailty. Intra-individual variability (IIV) of cognitive performance, which refers to the within-person trial-to-trial variation in reaction time during cognitive tasks, may be a useful predictor for falls in older adult ...

Background: Cognitive and motor deficits have been found to be important markers of Mild Cognitive Impairment (MCI), a pre-dementia risk state. Recently, aerobic exercise (AE) and cognitive training (CT) interventions significantly improved cognitive and motor function in older adults with MCI. R ...

Background: In recent years, many studies have investigated the effects of non-pharmacological interventions (e.g. physical and cognitive training) on cognition in patients with mild cognitive impairment. The SYNERGIC trial showed that combining physical exercise and cognitive training leads to g ...

Background: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causative agent of COVID-19 and has infected >700 million persons worldwide. Individuals infected with SARS-CoV-2 are at risk for cognitive decline and at higher risk of dementia compared with those diagnosed with oth ...

Background: Physical activity is associated with higher myelin content in older individuals with cerebral small vessel disease (CSVD), a condition marked by demyelination. However, potential mechanisms underlying these associations remain understudied. High-density lipoprotein (HDL) is involved i ...

Background: Mild Cognitive Impairment (MCI) may be associated with the presence of the apolipoprotein E4 allele (APOE4), a genetic factor linked to accelerated cognitive decline. The SYNERGIC trial demonstrated that physical exercise (PE) involving aerobic and resistance training improves global ...

Background: Older adults with mild cognitive impairment (MCI) have a higher risk of gait impairments and falls; yet, the effects of multimodal interventions, including combinations of exercises with cognitive training, on improving their mobility remain unclear. Objectives: To investigate the sy ...

Introduction: The 24-hour activity cycle (24-HAC) includes physical activity (PA), sedentary behavior (SB), and sleep. The 24-HAC composition and brain health relationship in adults with mild cognitive impairment (MCI) remains underexplored. We examined associations between 24-HAC composition and gray matter (GM) volume. Methods: Cross-sectional study in ...
