Insights into therapeutic approaches for the treatment of neurodegenerative diseases targeting metabolic syndrome

Due to the significant energy requirements of nerve cells, glucose is rapidly oxidized to generate ATP and works in conjunction with mitochondria in metabolic pathways, resulting in a combinatorial impact. The purpose of this review is to show how glucose metabolism disorder invariably disrupts the normal functioning of neurons, a phenomenon commonly observed in neurodegenerative diseases. Interventions in these systems may alleviate the degenerative load on neurons. Research on the concepts of metabolic adaptability during disease progression has become a key focus. The majority of the existing treatments are effective in mitigating some clinical symptoms, but they are unsuccessful in preventing neurodegeneration. Hence, there is an urgent need for breakthrough and highly effective therapies for neurodegenerative diseases. Here, we summarise the interactions that various neurodegenerative diseases have with abnormalities in insulin signalling, lipid metabolism, glucose control, and mitochondrial bioenergetics. These factors have a crucial role in brain activity and cognition, and also significantly contribute to neuronal degeneration in pathological conditions. In this article, we have discussed the latest and most promising treatment methods, ranging from molecular advancements to clinical trials, that aim at improving the stability of neurons.
