This paper explores neuroplasticity in adults, focusing on scientific evidence that shows the adult brain can continue to change and adapt. It explains how neuroplasticity supports learning and cognitive function and may help protect against certain diseases. The paper also examines strategies to enhance neuroplasticity, while reviewing studies with negative results, thus offering a balanced perspective. In addition, the roles of social engagement and stress are discussed to show how the environment factors influence neuroplasticity. Finally, it reviews the modern advances as well as the current limitations in our understanding of the topic.
