摘要

Hippocampal neurogenesis is a pivotal process for cognitive adaptability, memory consolidation, and the regulation of emotions, all of which exhibit a decline as individual’s age and contribute to the onset of neurodegenerative and mood disorders. The disruption of neurogenesis adversely affects these cognitive functions, establishing a connection between memory impairments and emotional disturbances, including anxiety and depression. Recent empirical studies underscore the promising effects of creatine and L-arginine supplementation, in conjunction with physical exercise, in enhancing hippocampal neuroplasticity and fostering neurogenesis. Creatine, recognized for its critical involvement in energy metabolism, plays a supportive role in neuronal integrity and cognitive performance, while L-arginine enhances nitric oxide-mediated neurovascular coupling and trophic support, and physical exercise activates neurogenic pathways and elevates mood. This review delineates the intricate interactions among hippocampal neurogenesis, cognitive flexibility, memory, and emotional functionality in the context of aging-related pathologies. This discourse examines the potential synergistic effects of creatine, L-arginine, and physical exercise in combating age-associated cognitive and emotional deterioration by influencing neurogenic and metabolic processes within the hippocampal region. While previous literature has scrutinized these interventions in isolation, no research to date has amalgamated their collective mechanistic impacts on hippocampal neurogenesis. This review distinctly integrates bioenergetic and neurotrophic pathways to furnish a coherent viewpoint on the interplay between exercise and creatine in the context of cognitive aging. Grasping these interrelations yields novel insights into therapeutic modalities designed to enhance cerebral resilience and psychological well-being among the elderly population. This comprehensive framework presents promising opportunities for the prevention and management of cognitive deficits and mood disturbances via lifestyle modifications and nutritional strategies.
