In a recent review article published in the magazine Brain behavior and immunity integrativeResearchers investigated studies on human participants and animal models to evaluate a fermented food that is rich in probiotics, cognitive function, neurodegeneration and oxidative stress. They concluded that Kefir shows promise as a potential complementary treatment for Alzheimer’s disease, which offers neuroprotective benefits because of the anti -inflammatory and antioxidant properties. However, standardized formulations and large -scale clinical studies are needed to validate the therapeutic potential for human patients.

Monitoring and treatment of Alzheimer’s disease

Alzheimer’s disease makes a leading contribution to the global burden of dementia, good for about 60% of the cases, which leads to cognitive decline and memory loss. By 2050, the prevalence is expected to rise to 150 million as the population continues to age. Symptoms of this disease are confusion, language problems and memory loss, which ultimately seriously influence behavior and condition, which leads to loss of independence.

There is currently no cure for this condition and current treatments are mainly focused on managing symptoms. However, emerging approaches are aimed at reducing the accumulation of tau proteins and beta-amyloid plaques, of which researchers have shown to facilitate the disease by the atrophy and damage to brain cells by chronic inflammation linked to microglial overactivation. In addition, dys regulation in insulin signaling and oxidative stress is involved in the progression of the disease, which strengthens the need for multi-oriented treatment strategies. Diagnostic progress has also enabled doctors to detect early risk factors by checking biomarkers in cerebrospinal liquid and blood, causing the focus to prevent prevention.

Lifestyle adjustments and the risk of Alzheimer’s

Although some cases are inherited, most cases of Alzheimer’s are sporadically and influenced by aging, lifestyle and medical conditions such as obesity, diabetes and hypertension. Research suggests that managing these risk factors can prevent more than 30% of the cases. Gut Health also plays a role, because an imbalance in intestinal bacteria can activate inflammation via routes such as the TLR4/MyD88/NLRP3 -SigneringCascade and cognitive decline.

Lifestyle changes, in particular diet, have been identified as a useful way to reduce risk factors. Fermented foods are rich in probiotics, which are being investigated because of their potential to strengthen the cognitive function in people with Alzheimer’s. Such foods contain favorable connections that can reduce neuro inflammation and oxidative stress, both important factors in the progression of the disease.

Probiotics stand out because it has a rich composition of microbes and nutrients, which in addition to probiotics contain minerals, vitamins and proteins. However, its microbial composition can vary considerably, depending on the production methods, so that comparisons between studies are complicated. Standardizing these formulations will be crucial for guaranteeing reproducibility in future clinical applications. Recent research suggests that Kefir can support the health of the brain by reducing oxidative damage and inflammation and modifying insulin signaling routes, such as the PI3K/AKT/GSK-3β/MTOR axis, which plays a key role in neuronal survival and synaptic plasticity. In this review, researchers systematically identified and assessed studies on the effects of Kefir on Alzheimer’s disease.

This figure illustrates the role of intestinal dysbiosis in neuro inflammation and the pathophysiology of Alzheimer’s disease. Dysbiotic intestinal microbiota activates inflammatory routes, leading to increased oxidative stress. This in turn causes microglial activation in the central nervous system. Activated microglia then stimulate astrocytes, resulting in the disruption of the blood-brain barrier (BBB), which continues the microglial activation in a vicious circle. BBB compromise and microglial activation contribute to the formation and deposit of beta-amyloid plaques and neurofibrillary tangles, by hyperphosphoryling of tau protein, which promote neuronal apoptosis, synaptic dysfunction and disease progression.

Limited proof of human studies

Researchers identified seven relevant studies from five medical databases, including only one human participants. In this study, 13 patients with Alzheimer’s disease received Kefir supplementation; The analysis showed that their oxidative stress and inflammatory markers decreased, while their motor skills, cognitive functioning and memory improved. In particular, patients showed an improvement of 28% in MMSE scores (MMSE) scores (MMSE) and approximately 66% and 62% improvements in immediate and late memory tests respectively. Another study that was cited in the assessment (Agahi et al., 2018), however, found no cognitive benefits in severe Alzheimer’s patients, which emphasizes the need for further research into dosing, microbial composition and stage-specific effects of kefir supplementation.

It regulates the immune system by promoting tolerance for non-pathogenic stimuli and competing with pathogens. The microbiota influences the intestinal brain axis due to bidirectional nerve communication and blood flow transport of bacterial metabolites, toxins and fragments that influence brain function and inflammation. It helps with metabolism by producing fatty acids with short chains, converting bile acids and synthesizing digestive enzymes, while contributing to the production of vitamin production. A healthy microbiota maintains the intestinal barrier, which prevents harmful bacterial by -products from translocation to the bloodstream and protecting systemic and neurological health (Leblanc et al., 2013).

Lessons of rodent and flight models

Of the remaining studies, four rodent participants, namely mice, albino rats and Wistar rats, include. These studies were aimed at changing brain tissue, neuro inflammation and cognitive function. A research article showed that Kefir changed the intestinal microbiome, reducing brain inflammation through TLR4 -Pathway modulation and improving cognitive function. In addition, Kefir supplementation was associated with reduced beta-amyloid accumulation, hippocampal neuron conservation and improved learning capacity in rodent models.

Another study showed that combining stem cell therapy with kefir effectively protects against oxidative stress and neuro inflammation. Rodents treated with pioglitazone, an anti-diabetical medicine and kefir showed reduced neuronal damage and memory, while Simvastatin (a lipid-lowering medication) and Kefir jointly reduced neuro inflammation and oxidative stress.

Two studies investigated the effects of kefir on amyloid structure and neurodegeneration using flight models. One discovered that Kefir is decreasing motor function and antioxidant activity increased and at the same time is decreasing amyloid accumulation, while the other showed that Kefir reduced the brain damage and at the same time improved motor skills and survival. In addition, biochemical analyzes in these models confirmed reductions in oxidative stress markers and improvements in neuronal survival.

Conclusions

Although symptom management is the primary approach in the current treatment of Alzheimer’s, often used drugs do not stop the progression of the disease, despite improving cognitive results. Diet approaches are increasingly considered to reduce the risk of developing the disease, with Kefir taking the focus because of the wealth in bioactive connections.

The integration of lifestyle and diet interventions with pharmacological treatments is necessary, in particular because Alzheimer’s is a complex disorder that is influenced by various factors. While Kefir shows promise in animal models and a single study involving human participants, its effects can depend on the composition and dosage of the microbial voltages. Clinical examinations and longitudinal studies are needed to assess the long -term effects of these and other probiotics, which generates evidence about its interactions with other measures to prevent cognitive decreases.

An extensive understanding of its efficacy and safety, including optimum doses and standardized formulations, is also needed to gauge its usefulness in therapeutic and clinical contexts. In addition, researchers emphasize that Kefir’s therapeutic potential is influenced by variations in microbial content and fermentation conditions, so that further standardization efforts are required for clinical implementation. Although a cure for Alzheimer’s disease does not remain available, emerging research offers promising strategies for improved screening, monitoring, prevention and management.
