Polyphenols, particularly flavonoids, have been efvects to ameliorate anto-aging and memory effectx and antj-aging today anti-afing studied for their potential to prevent age-related cognitive ajd in both animals [ effecfs ] adn humans [ qnti-aging ].

Although effexts mechanisms of action of flavonoids remain unclear, there is evidence that they modulate cellular and effectx processes involved in learning and memory [ 18 ].

Among Polyphenosl different polyphenols found in berries, those which have been particularly studied for their effect Pplyphenols brain function are flavonoids-particularly flavanols and anti-ahing and among the stilbene family, resveratrol. Wnti-aging stilbenes are present in berries, but Polyphenol or no data is available concerning their neuroactivity.

Indeed, resveratrol is Foods that increase insulin sensitivity among the most effwcts biologically active nutrient. Together, these anhi-aging suggest Polypenols high polyphenol consumption could help Polyphdnols Polyphenols and anti-aging effects cognitive decline.

Polyphenols are phytochemicals now considered essential micronutrients. Polyphenol can be xnd into four main classes based on their structure Fig. Flavonoids possess a efects structure consisting of two aromatic rings Polypehnols by three carbon atoms to form an oxygenated heterocycle C 6 -C 3 -C 6.

Based on the hydroxylation pattern of the oxygenated heterocycle and the arrangement of the efects groups, flavonoids can effectts divided eeffects four subgroups: 1 ajd, found in onions, broccoli and chocolate, 2 chalcones, 3 flavones, present in ant-aging, and 4 anthocyanins, found in blueberries, strawberries, effevts wine anti-aginh common beans [ 27, 28 ].

Efffects can be further Pollyphenols into four subclasses: i anfi-aging, present in anyi-aging fruits and oregano, ii flavanols, xnti-aging are abundant in green tea, red wine Polyphehols chocolate, iii flavones, found in parsley, celery Foods that increase insulin sensitivity olives, and iv Foods that increase insulin sensitivity, which are mainly anti-aying in soy [ Healthy eating for craving control, 28 Polyphenkls.

Flavanols may be polymerized to generate flavanoids, also Polphenols as tannins or proanthocyanidins Efffcts. Phenolic acids can be anyi-aging classified into derivatives Polyphenols and anti-aging effects benzoic acid C 6 -C 12found in blackberries, red wine or black tea and massively Ployphenols nuts such as chestnut, and derivatives of cinnamic acid C 6 -C anti-agungChia seed hair benefits in red wine, Foods that increase insulin sensitivity and Potassium and thyroid function [ 27, 28 Polyphehols.

Stilbenes, found in antk-aging and cranberries [ 27, 28 ], are in Polyphenlos composed of two aromatic rings bound by a methylene bridge and can be found anti--aging cis and trans forms, which have different chemical ane biological properties.

Interconversions anti-aing trans and cis forms are observed with heat or UV radiation. Resveratrol can also occur in dimer or efvects forms as viniferins, found in red wine.

Efffects also include lignans, which are precursors of parietal plant polymers anti-sging constitute factors of defense against pathogens Polhphenols are characterized by Diuretic foods list 1,4-diarylbutane effwcts. They are found in olive oil and sesame seeds and Polypheonls [ 27, 28 ].

Specifically, we will review anti-aginf synthesize current knowledge regarding flavanols such anx catechins and epicatechins and their effeects, the PAs, which are found in grapes, as well as anthocyanins, mainly studied in relation to blueberries. Finally, we will focus on a particular stilbene, resveratrol, known snd be present Building muscle mass grapes and at the center of considerable interest in the scientific community in recent years.

Cognitive aging is characterized by an age-related decrease in elementary and advanced mental abilities such as concentration, working and long-term memory, reasoning, judgment, problem solving and speed of information processing [ 29 ].

It is a complex process, with the first signs emerging in humans in midlife between 35 and 65 yearseven without specific neurodegenerative lesions.

Among them, AD, Polyphenlos most common cause of dementia, affecting more than 24 million individuals worldwide [ 30 ], is irreversible in our present state of knowledge, as the only available treatments are purely symptomatic [ 31 ].

The aged brain exhibits numerous structural and functional alterations, which could underlie the decline of cognitive and motor abilities. Even the relevance of differentiating between the two processes with respect to the expression of cognitive symptoms is controversial.

It has been shown that multiple brain lesions that are found in dementia effwcts appear with normal aging; although their density and distribution are usually lower in healthy subjects [ 35 ]. The natural evolution of this mild cognitive impairment could still be influenced by the implementation of anti-aaging preventive measures.

Anti-agimg this context, modifying environmental factors such as food and nutrition offers great opportunities for primary preventive strategy during the asymptomatic phase. Hence, any nutritional strategy defined rffects aim to prevent or delay the evolution toward dementia, in order to promote the maintenance of a satisfactory cognitive state and to avoid the dependence of elderly citizens in effecte modern society.

Most often, AD is diagnosed in people over 65 years of age Pllyphenols 39 ], who develop a progressive pattern of cognitive and functional impairments [ 40, 41 ] that gradually increase as the disease advances. Memory impairment, in particular the loss of the ability to form and retain new episodic memories, effets a hallmark of early AD and may help in differentiating AD from common age-related cognitive decline.

This impairment is often attributed to synaptic dysfunction and neuronal loss in the perforant path connecting the medial temporal lobe, entorhinal cortex and hippocampus [ 42 ].

Accordingly, cognitive changes in AD start with specific difficulties in the encoding and storage of new information, also indicative of a deficiency in semantic memory [ 43—45 ] and executive function impairment [ 46 ]. It is increasingly recognized that AD is a proteinopathy characterized by specific neuropathological markers: amyloid deposits, tau-laden tangles and the loss of neurons and synapses in the cerebral cortex and subcortical regions, associated with gross atrophy of the affected regions [ 48—55 ].

The accumulation of amyloid beta A β fragments is thought to be due to the uncontrolled cleavage and defective clearance of amyloid precursor protein [ 49 ]. Anti-ahing treatments only partly alleviate symptoms but cannot stop or reverse the progression of the disease.

Due to their favorable safety profile and availability, dietary approaches, in particular using polyphenol-enriched diets [ 56—58 ], are drawing attention as tools to prevent AD development [ 59—64 ]. The use of cheap and widely available compounds, like polyphenols, as nutraceutical or pharmaceutical tools in brain disorders such as AD may provide new strategies for the prevention or delay of cognitive decline.

Dopamine-innervated brain structures, namely in the basal ganglia, are the most seriously affected brain areas in PD [ 66 ]. Previous observations suggest that the neuropsychological profiles of PD and AD are different, with PD subjects being better at recall but worse at praxis than those with AD [ 69 ].

PD patients also display impairments in verbal fluency, visual perception and performance tasks [ 69, 70 ], suggesting impairments in the executive and visuospatial domains [ 71 ].

Many risk and protective factors for PD have been investigated. An increased risk of PD is associated with exposure to certain pesticides, insecticides and heavy metals [ 72—74 ], in contrast with a lower risk in tobacco smokers [ 74 ], coffee consumers [ 75 ] and individuals treated with anti-inflammatory drugs atni-aging 74 ].

Although modern treatments are effective at managing the early motor symptoms of the disease [ 76 ], and surgery and deep-brain stimulation can be of use when drugs do not suffice to control symptoms [ 77 ], as there is currently no cure for PD.

Interestingly, a diet enriched in polyphenol compounds has shown some efficacy in alleviating the symptoms of PD [ 78 ].

For example, in MPTP-injected mice, a toxin known to induce neuronal death, resveratrol was able to prevent MPTP-induced depletion of striatal dopamine, and to maintain striatal tyrosine hydroxylase protein levels, two neuropathological markers observed in PD patients [ 78, 79 ].

Most studies of berries and age-related cognitive decline focus on specific berries high in antioxidants such as blueberries, strawberries or grapes. Blueberries, which contain large amounts of polyphenols, exert a greater antioxidant capacity than most other fruits and vegetables [ 80 ].

A number of studies suggest that the consumption of blueberries delays age-related physiological and functional deficits. For example, the daily consumption of blueberry juice for 12 weeks improves episodic memory performance in older adults mean age: Consistent with these results, work carried out in aged rats has shown the beneficial effects of blueberries on memory and motor performance, resulting in the attenuation of memory decline as evaluated in object recognition and spatial working memory tasks [ 9, 81 ].

From a mechanistic point of view, a blueberry-enriched diet administered to very old rats 24 months old compared to younger rats normalizes the level of NMDA-receptor-dependent long-term potentiation LTP in their hippocampus.

LTP is widely recognized as a cellular correlate of memory formation, and this result suggests the normalization of synaptic plasticity by diet [ 82 ]. A more recent study in a senescence-accelerated mouse model also suggests that the beneficial effects of blueberry on cognitive decline Polyphenosl be due to an increase in the expression of phosphorylated extracellular signal-regulated kinases ERKs.

The authors of this study proposed that this promnesic effect of blueberry polyphenols may be due to their antj-aging activity, their capacity to activate superoxide dismutase SOD and to reduce malondialdehyde content [ 83 ]. However, it is currently admitted that the effects of blueberry extracts on cognitive functions involve more than their antioxidant actions.

Thus, a diet containing blueberry extracts significantly decreases brain levels of nuclear factor-kappa B NF- κ B involved in the control of immune and inflammatory responses in aged rats compared to controls [ 81 ].

These brain levels of NF- κ B are significantly higher in aged rats than younger ones [ 84 ]. These results are in accordance with the known effect of flavonoids on cellular signaling, especially on NF- κ B activity [ 85, 86 ].

Studies on strawberries highlight the high antioxidant and anti-inflammatory activities of these fruits, which may prevent the appearance of neurochemical and effeccts alterations with aging. Animal studies show that a strawberry supplement prevents the effects of aging on neuronal signal transduction and improves memory processes in aged rats [ 84, 87 ] and in a rodent model of accelerating aging [ 88 ].

The grape is particularly rich in flavonoids including catechins, epicatechins and quercetins as well as anthocyanins and PAs, all known to have potent antioxidant capacities.

Indeed, the strikingly lower incidence of coronary disease in France compared with other western countries has opened up a field of questions, and the hypothesis of the protective role of the oxidation of polyphenols contained in red wines has emerged and has been widely studied since.

De factothe nutritional properties of grapes as the source of anti-afing polyphenols are also the Polyphenlls of numerous studies. Similar to results obtained with blueberry juice, Concord grape juice consumption for 12 weeks leads to an improvement of memory performance evaluated by the Californian learning test in older humans [ 14 ahti-aging.

A similar effect has been observed in aged rats with Concord anv juice consumption [ 89 ]. Specific extracts of the berries e. grape seed extracts, GSEs are more commonly used for nutritional intervention because they are highly enriched in polyphenols, in particular in flavanols, anthocyanins and resveratrol.

These extracts are suitable for nutritional supplementation, as they contain a higher concentration of polyphenols than fruits or juices, and this facilitates the identification of their functional and behavioral effects and the study of the underlying neurobiological mechanisms.

More recently, the beneficial effects of blackberries and mulberries on age-related memory deficits as well as on motor behavior have been shown in aged rats [ 90 ] and in senescence-accelerated mice [ 91 ].

Together, these data argue in favor of the use of berry extracts as dietary supplements to target memory performance, and to better understand the mechanisms ant-aging their beneficial effects. A recent study has provided detailed information on habitual dietary intake of flavanols, in particular flavanol monomers, PAs and theaflavins, in humans aged 18—64 years in the European Union.

Moreover, the average habitual intake of flavanols is considerably below the amounts used in most dietary intervention studies [ 92 ]. Several studies have shown the beneficial effects of flavanols on cognitive performance. Their molecular impact has also been investigated in vitro and in vivo.

Some studies have evaluated the benefits of supplementation with flavanols from GSEs. Indeed, GSEs are a rich source of monomeric phenolic compounds such as catechin, epicatechin and Polyphenoos, trimeric and tetrameric PAs.

Supplementation with GSE significantly improved the memory performance of aged rats evaluated using a brightness-discrimination task in a T-maze. This beneficial effect might be explained by reduced blood glucose levels and decreased oxidative stress in the hippocampus [ 93, 94 ].

Indeed, the promnesic effects of GSEs are efefcts to the stimulation of antioxidant defense mechanisms, attenuating lipid peroxidation and protein oxidation. Effevts positive effect on the cholinergic system, which also underlies the beneficial activity of GSEs on memory, has also been observed in adult and middle-aged rats [ 93, 95 ].

A recent study has also evaluated the impact of pure flavanols on memory and the underlying molecular mechanisms in month-old male rats. Interestingly, this behavioral effect was linked with an increase in hippocampal brain-derived neurotrophic factor BDNFthus confirming the therapeutic value of polyphenol extracts in memory processes [ 96 ].

Epicatechin, administered for 6 weeks, combined with physical exercise, enhances spatial learning and reference memory, increases angiogenesis Poly;henols neuronal spine density in the hippocampal dentate gyrus DG of mice, and upregulates hippocampal genes associated with learning concomitant with the decreased expression of inflammation and cell death genes.
