It represents an intermediate stage between normal aging and dementia, and a crucial opportunity for intervention prior to extensive cognitive decline. Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, has shown promise in enhancing global cognition in MCI. Current evidence suggests that tDCS provides short-term cognitive benefits, particularly in memory and attention, with moderate effects observed in processing speed. However, its impact on executive function and language remains inconsistent, highlighting variability in individual responses and study methodologies. While long-term efficacy remains uncertain due to limited longitudinal research and short follow-up periods, safety concerns, especially with self-administered tDCS such as in home-based tDCS, underscore the need for proper training and device innovation. Despite this, tDCS is a promising, portable tool for cognitive enhancement in MCI, with potential to delay progression to dementia. Addressing challenges such as optimizing stimulation protocols, accounting for individual neuroanatomical variability, and establishing long-term effectiveness will be essential for its broader clinical adoption. Future research should focus on standardizing methodologies, incorporating biomarkers to predict treatment response, and conducting large-scale, longitudinal studies to refine its therapeutic application.</p>","PeriodicalId":94372,"journal":{"name":"Chonnam medical journal","volume":"61 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11821984/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143434889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, low levels of ROS constitute important redox-signaling molecules in various pathways that maintain cellular homeostasis and regulate key transcription factors. As a result, ROS can affect various cellular processes, such as apoptosis, migration, differentiation, and proliferation. ROS can act as signaling molecules, controlling various normal physiological activities at the cellular level.

Metformin notably decreased the incidence of T2DM by 31% and it exerts its effects through various signaling pathways. Databases searched included PubMed, Google Scholar, and Scopus from 2000 to 2024. One of the primary mechanisms involves AMPK activation which causes reduced lipogenesis and improved fatty acid oxidation in the liver and muscles. Key molecules affected by metformin include acetyl-CoA carboxylase (ACC) and sterol regulatory element-binding protein 1c (SREBP-1c), both involved in lipid synthesis regulation. Aerobic exercise has also emerged as a crucial component in managing T2DM due to its improved effects on hyperglycemia and insulin sensitivity. Key signaling pathways affected in T2DM include the PI3K/Akt, AMP-activated protein kinase (AMPK), and MAPK/ERK pathways which play essential roles in regulating glucose homeostasis, glycogenesis, and insulin secretion. When comparing the mechanisms and efficacy of aerobic exercise and metformin, it becomes evident that aerobic exercise primarily enhances physical fitness and metabolic function, while metformin exerts its effects through biochemical pathways involving AMPK activation. Aerobic exercise and metformin are effective for managing T2DM, though they operate through different mechanisms. Regular aerobic exercise improves insulin sensitivity, enhances cardiovascular health, and promotes weight loss, while metformin primarily decreases hepatic gluconeogenesis and enhances insulin secretion. Understanding the intricate signaling pathways affected by metformin and aerobic exercise provides valuable insights into its mechanisms of action and clinical implications for treating diabetic patients effectively.</p>","PeriodicalId":94372,"journal":{"name":"Chonnam medical journal","volume":"61 1","pages":"9-18"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11821983/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143434822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
