Unraveling the Interplay Between Metabolism and Neurodevelopment in Health and Disease

Neurodevelopment is a multifaceted and tightly regulated process essential for the formation, maturation, and functional specialization of the nervous system. It spans critical stages, including cellular proliferation, differentiation, migration, synaptogenesis, and synaptic pruning, which collectively establish the foundation for cognitive, behavioral, and emotional functions. Metabolism serves as a cornerstone for neurodevelopment, providing the energy and substrates necessary for biosynthesis, signaling, and cellular activities.

Key metabolic pathways, including glycolysis, lipid metabolism, and amino acid metabolism, support processes such as cell proliferation, myelination, and neurotransmitter synthesis. Crucial signaling pathways, such as insulin, mTOR, and AMPK, further regulate neuronal growth, synaptic plasticity, and energy homeostasis. Dysregulation of these metabolic processes is linked to a spectrum of neurodevelopmental disorders, including autism spectrum disorders (ASDs), intellectual disabilities, and epilepsy.

This review investigates the intricate interplay between metabolic processes and neurodevelopment, elucidating the molecular mechanisms that govern brain development and the pathogenesis of neurodevelopmental disorders. Additionally, it highlights potential avenues for the development of innovative strategies aimed at enhancing brain health and function.
