Abstract Context Resveratrol (RV), a natural compound found in grapes, berries, and peanuts, has been extensively studied for its potential treating Alzheimer’s disease (AD). RV shown promise inhibiting the formation of beta-amyloid plaques (Aβ) neurofibrillary tangles (NFTs), protecting against neuronal damage oxidative stress, reducing inflammation, promoting neuroprotection, improving function blood–brain barrier (BBB). However, conflicting results have reported, necessitating comprehensive umbrella review systematic reviews to provide an unbiased conclusion on therapeutic effectiveness AD. Objective The objective this study was systematically synthesize evaluate meta-analysis investigating role AD using data from both human animal studies.

Dementia is a growing public health concern, with an estimated prevalence of 57 million adults worldwide. Alzheimer’s disease (AD) accounts for 60–80% the cases. Clinical trials testing potential drugs and neuroprotective agents have proven futile, currently approved only provide symptomatic benefits. Emerging epidemiological clinical studies suggest that lifestyle changes, including diet physical activity, offer alternative therapeutic route slowing preventing cognitive decline dementia. Age single most common risk factor dementia, it associated cellular bioenergetics metabolic processes. Therefore, nutrient-rich critical optimal brain health. Furthermore, type 2 diabetes (T2D) AD, diets reduce T2D may confer neuroprotection. Foods predominant in Mediterranean, MIND, DASH diets, fruits, leafy green vegetables, fish, nuts, olive oil, prevent or slow decline. The mechanisms by which these nutrients promote health, however, are not yet completely understood.

Published: Aug. 10, 2024

This narrative review synthesizes current evidence regarding anti-inflammatory dietary patterns and their potential benefits for individuals with mental disorders neurodegenerative diseases. Chronic low-grade inflammation is increasingly recognized as a key factor in the etiology progression of these conditions. The examines neuroprotective properties components food groups, focusing on whole foods rather than specific nutrients or supplements. Key showing include fruits vegetables (especially berries leafy greens), grains, legumes, fatty fish rich omega-3, nuts (particularly walnuts), olive oil, fermented foods. These are generally antioxidants, fiber, bioactive compounds that may help modulate inflammation, support gut health, promote neuroprotection. Conversely, ultra-processed foods, red meat, sugary beverages be harmful. Based this evidence, we designed Brain Anti-Inflammatory Nutrition (BrAIN) diet. mechanisms diet modulation microbiota gut-brain axis, regulation inflammatory pathways, reduction oxidative stress, promotion neuroplasticity.

Factors Affecting Resilience and Prevention of Alzheimer's Disease and Related Dementias

Annals of Neurology, Journal Year: 2024, Volume and Issue: 96(4), P. 633 - 649

Published: Aug. 17, 2024

Alzheimer's disease (AD) is a devastating, age‐associated neurodegenerative disorder and the most common cause of dementia. The clinical continuum AD spans from preclinical to subjective cognitive decline, mild impairment, dementia stages (mild, moderate, severe). Neuropathologically, defined by accumulation amyloid β (Aβ) into extracellular plaques in brain parenchyma cerebral vasculature, abnormally phosphorylated tau that accumulates intraneuronally forming neurofibrillary tangles (NFTs). Development treatment approaches prevent or even reduce decline because has been slow compared other major causes death. Recently, United States Food Drug Administration gave full approval 2 different Aβ‐targeting monoclonal antibodies. However, this breakthrough modifying approach only applies limited subset patients there are stringent eligibility criteria. Furthermore, these do not progression disease, AD‐related pathologies, such as NFTs, directly targeted. A non‐mutually exclusive alternative address lifestyle interventions can help risk dementias (ADRD). It estimated addressing modifiable factors could potentially delay up 40% AD/ADRD cases.

Abstract Alzheimer's disease (AD) is a degenerative characterized by progressive cognitive dysfunction. The strong link between nutrition and the occurrence progression of AD pathology has been well documented. Poor nutritional status accelerates progress potentially aggravating amyloid beta (Aβ) tau deposition, exacerbating oxidative stress response, modulating microbiota–gut–brain axis, disrupting blood–brain barrier function. advanced stage tends to lead malnutrition due impairments, sensory dysfunctions, brain atrophy, behavioral psychological symptoms dementia (BPSD). This, in turn, produces vicious cycle AD.

The two major determining factors for Alzheimer's disease (AD) are genetics and lifestyle. Alleles of the apolipoprotein E (APOE) gene play important roles in development late-onset AD, with APOEɛ4 increasing risk, APOEɛ3 being neutral, APOEɛ2 reducing risk. Several modifiable lifestyle have been studied terms how they can modify risk AD. Among these dietary pattern, nutritional supplements such as omega-3 fatty acids, B vitamins, physical exercise, obesity, vitamin D.
