Recent clinical evidence suggests that central insulin resistance acts as a fundamental driver in several neurodegenerative and psychiatric conditions. While clinicians traditionally link metabolic abnormalities to the periphery, impaired insulin signaling within the brain contributes significantly to cognitive decline. Consequently, understanding this shared pathophysiological mechanism offers a new frontier for therapeutic intervention.
In the brain, insulin regulates glucose uptake, synaptic plasticity, and neuronal survival. However, central insulin resistance triggers a cascade of neurobiological vulnerability. This process promotes neuroinflammation and impairs the stability of neuronal networks. Furthermore, it alters brain energy metabolism, which leads to mitochondrial dysfunction. Researchers find these changes across a spectrum of disorders, including Alzheimer’s disease and epilepsy. Therefore, metabolic dysfunction compromises the brain’s flexibility and accelerates disease progression.
Addressing metabolic dysfunction through personalized nutritional interventions shows significant promise. For instance, dietary patterns such as the ketogenic diet provide an alternative fuel source for the brain. Specifically, ketones bypass the impaired glucose pathways associated with central insulin resistance. In addition, energy restriction and intermittent fasting can partially restore insulin sensitivity. Recent studies indicate that these lifestyle changes improve cognitive outcomes and behavioral stability. Thus, clinicians should consider metabolic phenotyping as a powerful tool for adjunctive management.
Peripheral resistance affects muscle and liver glucose uptake, but central resistance disrupts neurotransmitter signaling, neuroplasticity, and the brain's inflammatory response directly.
Emerging studies suggest that ketosis provides an alternative energy source that bypasses impaired glucose transport, which effectively restores brain energy levels and metabolic flexibility.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
