EFFETTO DEGLI ESTRATTI DI PAPAYA FERMENTATA SULLO STRESS OSSIDATIVO IN PAZIENTI CON MALATTIA DI ALZHEIMER

2013

Brain tissue is particularly susceptible to oxidative damage, which has been associated with pathological findings of Alzheimer's disease (AD), such as amyloid plaques and protein fibrils. Oxidative stress alterations, including increased production of reactive oxygen metabolites, decline of antioxidant systems, and decreased efficiency in repairing molecules, have been linked to the development of AD. Postmortem studies on brain tissue from AD patients have shown several oxidative damage markers, such as increased lipid peroxidation, oxidative damage of proteins, glyco-oxidation, and reduction of antioxidant systems. We studied 40 patients referred to our Geriatric Unit (age 78,2 ± 1,1 yea…

Biomarkers clinici, biologici, cognitivi e comportamentali per la malattia di Alzheimer ed il Mild Cognitive Impairment: dati di popolazione dello Za…

Nel 2015, quasi 47 milioni di persone in tutto il mondo sono state colpite da demenza, e si prevede che i valori raggiungeranno 75 milioni entro il 2030 e 131 milioni entro il 2050, con il maggiore aumento previsto nei paesi a basso e medio reddito. Nonostante gli enormi costi dell'assistenza medica e sociale per i pazienti affetti da AD dipendano dalla gravità della malattia, i dati sulla prevalenza della demenza sulla base della gravità o dello stadio sono carenti soprattutto nei contesti rurali e con basso livello di istruzione. L'obiettivo principale di questo studio è di valutare l'interazione tra fattori di rischio legati alla fragilità, le performance cognitive e i sintomi comportame…

Cognitive Frailty: An Update

2021

This review article provides an update of the empirical research on cognitive fragility conducted in the last four years. The studies retrieved were classified in four different categories. The first category includes articles relating cognitive frailty to cognitive reserve and which continue to highlight the importance of educational level. The second category includes recent research on cognitive fragility biomarkers, involving neuroimaging, metabolism and, in a novel way, microbiota. The third category includes research on how cognitive frailty is related to motor development and physical functioning, exploring e.g. the use of technology to study motor markers of cognitive frailty. Final…

Mild cognitive decline. A position statement of the Cognitive Decline Group of the European Innovation Partnership for Active and Healthy Ageing (EIP…

2016

Introduction: Mild cognitive impairment (MCI) is a term used to describe a level of decline in cognition which is seen as an intermediate stage between normal ageing and dementia, and which many consider to be a prodromal stage of neurodegeneration that may become dementia. That is, it is perceived as a high risk level of cognitive change. The increasing burden of dementia in our society, but also our increasing understanding of its risk factors and potential interventions, require diligent management of MCI in order to find strategies that produce effective prevention of dementia. Aim: To update knowledge regarding mild cognitive impairment, and to bring together and appraise evidence abou…

The Effect of Adherence to the Mediterranean Diet on Late-Life Cognitive Disorders: A Systematic Review

2020

Objectives: Although some results are conflicting, numerous investigations have demonstrated that the Mediterranean Diet (MedDiet) has positive effects on brain health. This review intends to provide an update on the scientific evidence regarding the effects of adherence to the MedDiet on late-life cognitive disorders. Design: A systematic review was performed. The PubMed and Scopus databases were searched for longitudinal studies and randomized controlled trials (RCTs) published between the databases’ inceptions and May 4, 2020. PRISMA guidelines were followed; the quality of the studies was assessed using version 2 of the Cochrane risk-of-bias tool for the RCTs and the Newcastle-Ottawa Sc…

Dietary Approaches and Supplements in the Prevention of Cognitive Decline and Alzheimer';s Disease

2016

Age-associated cognitive decline and dementia are conditions in which there is deterioration in memory, thinking, and behavior, with profound effects on the ability to perform everyday activities and well-being. Even if dementia mainly affects older persons, it is not a normal part of aging. Alzheimer's disease accounts for 60-75% of dementia cases. The number of persons affected will increase in the next decades in parallel with aging of the world population. Hence, unless some approach is found to reduce age-related deterioration of cognitive functions, health care costs will continue to rise exponentially. There is a wealth of epidemiological evidence supporting a relationship between di…

The relationship between Polypharmacy and Trajectories of Cognitive Decline in People with Dementia: a large representative cohort study

2019

Polypharmacy, defined through the number of medications prescribed, has been linked to a range of adverse health outcomes in people with dementia. It is however unclear whether a numerical threshold of concurrently prescribed drugs is a suitable predictor for cognitive decline. We aimed to test associations between polypharmacy and both short-term (six months) and long-term (three years) cognitive trajectories in patients with incident dementia. Using data from a large mental health and dementia care database in South London, a cohort of 12,148 patients (mean age = 80.7 years, 61.1% female, mean MMSE = 18.6) clinically diagnosed with dementia was identified. We determined the number of medi…

Blood pressure and LDL-cholesterol targets for prevention of recurrent strokes and cognitive decline in the hypertensive patient : design of the Euro…

2014

BACKGROUND AND OBJECTIVES:: The SBP values to be achieved by antihypertensive therapy in order to maximize reduction of cardiovascular outcomes are unknown; neither is it clear whether in patients with a previous cardiovascular event, the optimal values are lower than in the low-to-moderate risk hypertensive patients, or a more cautious blood pressure (BP) reduction should be obtained. Because of the uncertainty whether 'the lower the better' or the 'J-curve' hypothesis is correct, the European Society of Hypertension and the Chinese Hypertension League have promoted a randomized trial comparing antihypertensive treatment strategies aiming at three different SBP targets in hypertensive pati…

Pain is not associated with cognitive decline in older adults: A four-year longitudinal study.

2018

The finding of a potential association between pain and cognitive decline is limited to a few cross-sectional studies with relatively samples. We therefore aimed to investigate whether the presence and severity of pain at baseline could predict a decline in cognitive function over four years of follow-up in the English Longitudinal Study of Ageing. At baseline, participants with no dementia who were “often troubled by pain” were considered to have pain. Pain severity was categorized as mild, moderate, or severe. Cognitive function was explored through verbal fluency (assessed by asking how many different animals the participants could name in 60 s), memory (sum of immediate and delayed verb…

Blood pressure and low-density lipoprotein-cholesterol lowering for prevention of strokes and cognitive decline: a review of available trial evidence.

2014

BACKGROUND AND OBJECTIVES:: It is well established by a large number of randomized controlled trials that lowering blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) by drugs are powerful means to reduce stroke incidence, but the optimal BP and LDL-C levels to be achieved are largely uncertain. Concerning BP targets, two hypotheses are being confronted: first, the lower the BP, the better the treatment outcome, and second, the hypothesis that too low BP values are accompanied by a lower benefit and even higher risk. It is also unknown whether BP lowering and LDL-C lowering have additive beneficial effects for the primary and secondary prevention of stroke, and whether these…
