OBJECTIVE Vitamin D (VD) deficiency is an independent risk factor for cognitive impairment (CI) in the general population, but VD status in peritoneal dialysis (PD) patients has not been investigated. In this study, we aimed to investigate the relationship between serum VD levels and global and specific cognitive functions in PD patients. DESIGN AND SETTING Cross-sectional study, simultaneous...

This study examines the association between sodium intake and its interaction with physical activity on cognitive function over 3 years in older adults residing in Québec, Canada. We analyzed a subgroup from the NuAge cohort (aged 67-84 years) with nutrient intake data, including sodium, from a food frequency questionnaire administered at baseline. Baseline physical activity was assessed using ...

Neurones in visual cortex are known to show increasing response latency with decreasing stimulus contrast [1-5,7,9]. Neurophysiological recordings from neurones in inferior temporal cortex (IT) and the superior temporal sulcus (STS), show that the increment in response latency with decreasing stimulus contrast is considerably greater in higher visual areas than that seen in primary visual corte...

Introduction Cognitive decline is common and increases mortality risk in hemodialysis patients. Intradialytic interventions like cognitive training (CT) and exercise training (ET) may preserve cognitive function. Methods We conducted a pilot randomized controlled trial of 20 hemodialysis patients to study the impact of 3 months of intradialytic CT (tablet-based brain games) (n = 7), ET (foot ...

Background Amyloid pathology, vascular disease and hippocampal atrophy are associated with cognitive trajectories in older adults. However, there is almost no prior evidence on how these pathologies influence cognition the oldest-old. Method We included 216 individuals from The 90+ Study, a longitudinal study of aging dementia people aged 90 years older, who had 18F-florbetapir PET MRI imaging....

BACKGROUND Obesity impairs cognition and health-related quality of life (HRQOL) in older adults; however, the appropriate treatment of obese older adults remains controversial. OBJECTIVE The objective was to determine the independent and combined effects of weight loss and exercise on cognition, mood, and HRQOL in obese older adults. DESIGN One hundred seven frail, obese older adults were r...

OBJECTIVES To examine the natural course of depressive symptoms in patients with probable Alzheimer's disease (AD), specifically, the temporal relationship between depressive symptoms, function, and cognitive status. DESIGN Multicenter cohort study with follow-up of up to 14 years. SETTING Patients from the two Multicenter Study of Predictors of Disease Course in Alzheimer's Disease (Predic...
