Enhancing cognition: The power of neuroplasticity

Abstract

Cognitive enhancement and neuroplasticity are interconnected terms. Neuroplasticity is an intrinsic brain capability that enables it to adapt and learn throughout life. It involves significant reorganization of neural circuits which is evident not only during normal human development but also occurs following early injury. As aging exerts a detrimental effect on various bodily systems, the extent of neuroplasticity also declines considerably. Recent evidences emphasize that cognitive enhancement can lead to positive neuroplastic changes. Moreover, neuroplastic mechanisms can be harnessed for therapeutic purposes in clinical populations in an effective manner. This approach can also pave a way for cognitive reserve and healthy aging, facilitating the protection against age-associated cognitive impairment and development of neurodegenerative disorders. However, there is an urgent need for more rigorous scientific methods to assess the effectiveness of these interventions, which is crucial for progressing in this area. In this review we aim to illuminate the promising potential of plastic processes in the nervous system. The integrated approach, combining neuromodulatory techniques such as brain stimulation with cognitive enhancement methods, is intriguing and could offer a new avenue for enhancing cognitive functions. Overall, this paper lays the groundwork for further exploration and emphasizes the importance of developing effective interventions that leverage the brain's capacity for change. Future research must refine the methodologies used to measure outcomes, ensure generalization and practical applicability, and develop strategies for implementation in real-world settings. This will ultimately enhance our understanding of how to optimize cognitive health throughout the lifespan.
