Alzheimer's disease (AD) is one of the most common forms of dementia, which cannot be cured at the moment. Therefore, researchers also look for the alternative approaches to its treatment. It is suggested that changes in human gut microbiome mediated by exercise could influence the development and progression of AD and a new term "muscle-gut-brain axis" is introduced. There is much evidence to support this assumption. The gut microbiology is closely related to a wide range of diseases of the nervous system and therefore any negative qualitative and quantitative changes in the composition of the gut microbiota can potentially contribute to the pathophysiology of AD. Research shows that the treatment of intestinal dysbiosis with probiotics/synbiotics/eubiotics can prevent or alleviate the symptoms of these chronic neurological diseases. Studies also point to the positive effects of movement on the health of seniors. A positive correlation can be found between cognitive functions and physical stress, both in the elderly and in AD patients. Even short-term interventions with a relatively low frequency seem to produce positive results, while physical activities can be performed by using relatively simple and cost-effective means. In addition, physical activity can significantly modulate gut microbiome. Thus, it can be concluded that physical activity in humans seems to correlate with gut microbiome, which can prevent the incidence and development of AD.
