Your brain can be trained, much like your muscles - a neurologist explains how to boost your brain health

Your brain can be trained, much like your muscles, and a neurologist explains how to boost brain health. The core idea is that challenging the brain over time strengthens connections, while repeating the same tasks yields diminishing returns. Electroencephalograms, or EEGs, show that learning a new skill reorganizes brain rhythms and enhances coordination across neural networks. Neuroplasticity persists into adulthood, with research showing that the brain can form new connections when exposed to novelty and deliberate practice. Engaging in genuinely new activities—such as learning a language, dancing, or practicing a musical instrument—can increase brain volume and connectivity. But the brain also needs recovery; sustained effort without rest can blunt gains and raise the risk of mental fatigue. The takeaway is that novelty pushes the brain to pay attention, learn, and solve problems in unfamiliar contexts. Balanced challenges and rest, not constant strain, promote lasting cognitive benefits and everyday clarity. In daily life, varying routines and deliberately introducing new experiences may help protect against cognitive aging.
