Alzheimer's disease (AD) is a major subtype of neurodegenerative dementia caused by long-term interactions and accumulation multiple adverse factors, accompanied dysregulation numerous intracellular signaling molecular pathways in the brain. At cellular levels, neuronal milieu AD brain exhibits metabolic abnormalities, compromised bioenergetics, impaired lipid metabolism, reduced overall capacity, which lead to abnormal neural network activity neuroplasticity, thus accelerating formation extracellular senile plaques neurofibrillary tangles. The current absence effective pharmacological therapies for points urgent need investigate benefits non-pharmacological approaches such as physical exercise. Despite evidence that regular can improve dysfunction state, inhibit different pathophysiological associated with AD, influence pathological process exert protective effect, there no clear consensus on specific biological mechanisms underlying advantages Here, we review how exercise improves crucial processes disorders including glucose Aβ metabolism transport, iron tau pathology. How states health also presented. A better knowledge neurophysiological contribute development novel drugs improvement interventions.

Abstract Synaptic abnormalities are a cardinal feature of Alzheimer’s disease (AD) that known to arise as the progresses. A growing body evidence suggests pathological alterations neuronal circuits and synapses may provide mechanistic link between amyloid β (Aβ) tau pathology thus serve an obligatory relay cognitive impairment in AD. Brain-derived neurotrophic factors (BDNFs) play important role maintaining synaptic plasticity learning memory. Considering AD disorder, BDNF has attracted increasing attention potential diagnostic biomarker therapeutical molecule for Although depletion been linked with Aβ accumulation, phosphorylation, neuroinflammation apoptosis, exact mechanisms underlying effect impaired signaling on still unknown.

Multiple factors combined are currently recognized as contributors to cognitive decline. The main independent risk factor for impairment and dementia is advanced age followed by other determinants such genetic, socioeconomic, environmental factors, including nutrition physical activity. In the next decades, a rise in cases expected due largely aging of world population. There no hitherto effective pharmaceutical therapies treat age-associated dementia, which underscores crucial role prevention. A relationship among diet, activity, lifestyle with function has been intensively studied mounting evidence supporting these development decline chief cause disability globally. Several dietary patterns, foods, nutrients have investigated this regard, some encouraging disappointing results. This review presents current effects components, supplements, sleep social engagement on prevention or delay onset age-related dementia.

Abstract Alzheimer’s disease (AD) is a chronic neurodegenerative disease, with the characteristics of neurofibrillary tangle (NFT) and senile plaque (SP) formation. Although great progresses have been made in clinical trials based on relevant hypotheses, these studies are also accompanied by emergence toxic side effects, it an urgent task to explore underlying mechanisms for benefits prevent treat AD. Herein, animal experiments few trials, neuroinflammation AD characterized long-term activation pro-inflammatory microglia NOD-, LRR- pyrin domain-containing protein 3 (NLRP3) inflammasomes. Damaged signals from periphery within brain continuously activate microglia, thus resulting constant source inflammatory responses. The response exacerbates endoplasmic reticulum oxidative stress which triggers microglia-dependent immune responses, ultimately leading occurrence deterioration In this review, we systematically summarized sorted out that exercise ameliorates directly indirectly regulating central nervous system promoting hippocampal neurogenesis provide new direction exploring activity

Alzheimer’s disease (AD) is a progressive neurodegenerative in the elderly with dementia, memory loss, and severe cognitive impairment that imposes high medical costs on individuals. The causes of AD include increased deposition amyloid beta (Aβ) phosphorylated tau, age, mitochondrial defects, neuroinflammation, decreased synaptic connections, nerve growth factors (NGF). While animals moderate-intensity exercise restores hippocampal amygdala through levels p-AKT, p-TrkB, p-PKC Aβ, tau phosphorylation, precursor proteins (APP) AD. Aerobic (with an intensity 50–75% VO2 max) prevents volume reduction, spatial learning reduction increasing flexibility.
