INTRODUCTION: Kidney transplantation is beneficial in improving cognitive abilities in patients with chronic kidney disease; however, there is still uncertainty concerning which cognitive domains benefit and to what extent. AIM: In the present study, cognitive functioning of renal transplant recipients was compared to normative data. Sociodemographic and clinical parameters that were associated with low cognitive performance were identified. DESIGN: A total of 109 renal transplant recipients (63% men) participated in the study, with a mean age of 51...

Non-valvular atrial fibrillation (NVAF) increases the risk of stroke by three- to five-fold, especially in elderly patients, creating a huge burden on medical system as well as a negative impact on patients lives. Balancing efficacy and bleeding risk is a challenge when considering anticoagulation therapy in elderly patients, because of their frequent high risk of both stroke and bleeding. Real world data reveal the underuse of anticoagulation in the elderly, especially due to physicians' fear of bleeding, often neglecting the thromboembolic risk...

Objective Post-stroke cognitive impairment often afflicts stroke survivors and is a major obstacle both for cognitive and physical rehabilitation. Stroke risk scores ["Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, Stroke" (CHADS2) and "CHADS2 + creatinine clearance <60 mL/min" (R2CHADS2)] are used to assess the future risk of cardioembolic stroke in patients with atrial fibrillation (AF). However, congestive heart failure, hypertension, aging, diabetes mellitus, stroke, and renal dysfunction are also risk factors for cognitive impairment...

BACKGROUND: Recent studies in children have reported associations of urinary cadmium (U-Cd), used as biomarker of Cd body burden, with renal dysfunction, retarded growth and impaired cognitive development in children. Little is known, however, about factors influencing U-Cd in children and likely to act as confounders. METHODS: In a cross-sectional study involving 249 schoolchildren (mean age, 5.72 years; 138 boys), we measured the urine concentrations of cadmium, zinc, lead, albumin, alpha1-microglobulin (A1M), retinol-binding protein, β2-microglobulin and club cell protein (CC16)...

Chronic kidney disease (CKD) is a significant global health concern with limited treatment options. Oxidative stress and inflammatory responses have been implicated in the pathology of CKD. Patients with CKD are frequently affected with neurological complications that affect both the central and peripheral nervous system. Identification of effective treatment strategies are of much clinical value in the therapy of CKD. Tangeretin, a plant-derived flavonoid has been described to retain extensive pharmacological properties...

BACKGROUND AND PURPOSE: Type 2 diabetes mellitus (T2DM) is associated with diseases of the brain, kidney, and vasculature. However, the relationship between T2DM, chronic kidney disease, brain alterations, and cognitive function after stroke is unknown. We aimed to evaluate the inter-relationship between T2DM, impaired renal function, brain pathology on imaging, and cognitive decline in a longitudinal poststroke cohort. METHODS: The TABASCO (Tel Aviv brain acute stroke cohort) is a prospective cohort of stroke/transient ischemic attack survivors...

Patients suffering from cognitive decline such as mild cognitive impairment or neurodegenerative disorders including Alzheimer's dementia, vascular dementia, frontotemporal dementia, and Lewy body dementia are often accompanied by symptoms like psychosis, depression, agitation, and apathy. Aging increases not only the prevalence of dementia but also the development of kidney disorders, which had emerged as possible risk factor of cognitive impairment and dementia. However, a contribution of renal dysfunction to psychosis associated with cognitive decline remains to be investigated...

BACKGROUND: Grape and blueberry extracts are known to protect against age-related cognitive decline. However, beneficial effects achieved by mixing grape and blueberry extracts have yet to be evaluated in dogs, or their bioavailability assessed. Of concern to us were cases of acute renal failure in dogs, after their ingestion of grapes or raisins. The European Pet Food Industry Federation (2013) considers only the grape or raisin itself to be potentially dangerous; grape-seed extracts per-se, are not considered to be a threat...

Over the past decade, the prevalence of chronic kidney disease (CKD) has reached epidemic proportions. The search for novel pharmacological treatment for CKD has become an area of intensive clinical research. l-Carnitine, considered as the "gatekeeper" responsible for admitting long chain fatty acids into cell mitochondria. l-Carnitine synthesis and turnover are regulated mainly by the kidney and its levels inversely correlate with serum creatinine of normal subjects and CKD patients. Previous studies showed that l-carnitine administration to elderly people is improving and preserving cognitive function...

BACKGROUND: Impaired renal function and proteinuria have been associated with cognitive impairment and dementia. Chronic kidney disease is considered to be an independent risk factor for Lewy body spectrum disorders (LBD). However, few studies have mentioned an association between proteinuria and cognition in LBD. We investigated the relationship between proteinuria and cognitive dysfunction in patients with Parkinson's disease (PD) and dementia with Lewy bodies (DLB). METHODS: Among 186 patients with LBD, 53 had PD-normal cognition (PD-NC), 76 had PD-mild cognitive impairment (PD-MCI), 43 had PD-dementia (PDD) and 14 had DLB...

Impaired renal function is regarded as a risk factor for vascular disease, and is associated with an increasing pulse wave velocity. Both renal dysfunction and arterial stiffness are associated with cognitive impairment and dementia. However, there have been few studies that have evaluated the relationship between albuminuria and arterial stiffness and Alzheimer's disease (AD). We investigated renal dysfunction and arterial stiffness in AD, as compared to normal controls, patients with subjective memory impairment (SMI), and patients with mild cognitive impairment (MCI)...

BACKGROUND: Renal disease has been associated with greater risk of dementia and greater cognitive impairment. However, the relationship of lower renal function with long-term decline in specific domains of cognitive function remains unclear among community-dwelling, non-demented individuals. METHODS: Stroke- and dementia-free participants (n = 2,116) were enrolled in the Baltimore Longitudinal Study of Aging, a community-based, prospective, longitudinal study. Renal function was estimated by the inverse of serum creatinine adjusted for age, sex and race and (in sensitivity analyses) estimated glomerular filtration rate (eGFR) using the MDRD formula...
