The fundamental dependence of optimal brain function—including memory, focus, and executive control—on the stable and efficient metabolic processes occurring within the central nervous system and the periphery. This foundation is critically supported by consistent glucose regulation, mitochondrial health, and the appropriate utilization of key macronutrients. Disruption of this foundation leads directly to cognitive impairment and neurodegeneration.
Origin
This term is a synthesis of endocrinology, which governs metabolism, and cognitive neuroscience, which studies brain function. It emphasizes the clinical understanding that the brain is a highly metabolically demanding organ, with its performance inextricably linked to systemic energy balance. The concept underpins therapeutic strategies that address cognitive decline via metabolic correction.
Mechanism
The foundation is built upon efficient glucose transport across the blood-brain barrier and robust mitochondrial ATP production within neurons and glial cells. Hormones such as insulin and thyroid hormones are key modulators of this process. When metabolic flexibility is compromised, for instance through insulin resistance, neurons suffer from energy deficit and increased oxidative stress, directly impairing synaptic function and leading to cognitive dysfunction.
