Neuroplasticity is the brain’s power to rewire itself and make new connections in response to learning and stimulation. It’s this ever-changing process in the brain tissue that keeps you sharp—preserving memories and storing knowledge as you age—while fending off neurodegeneration, a condition that can lead to diseases such as Parkinson’s and Alzheimer’s. “Challenging your brain to learn something new—such as a foreign language or a musical instrument or even solving a riddle—has been shown, both in healthy individuals and patients dealing with mild cognitive impairment, to improve brain structures and neuroplasticity.”
