Keep Sharp

You can affect your brain's thinking and memory far more than you realize or appreciate, and the vast majority of people haven't even begun to try.

You can affect your brain's thinking and memory far more than you realize or appreciate, and the vast majority of people haven't even begun to try. Neuroplasticity defies aging. The human brain remains plastic throughout life, capable of rewiring itself in response to experiences and generating new brain cells under the right circumstances. This challenges the old belief that cognitive decline is inevitable with age. Research shows that healthy older adults can generate just as many new brain cells as younger people, particularly in the hippocampus - the brain's memory center. Cognitive reserve builds resilience. Through education, work, and stimulating activities, we can build cognitive reserve - a backup system that helps the brain improvise and find alternative routes when faced with challenges. This reserve acts as a buffer against cognitive decline and can even help counteract the effects of other risk factors. People with greater cognitive reserve are more likely to stave off degenerative brain changes associated with dementia or other brain diseases. Key factors in building cognitive reserve: Higher education levels Occupational achievements Engagement in leisure activities Learning new skills Socializing and maintaining strong relationships

Every day of your life, you can make your brain better, faster, fitter, and, yes, sharper. Physical activity boosts brainpower. Exercise is the single most important thing one can do to enhance brain function and resiliency to disease. It improves digestion, metabolism, body tone, strength, and bone density while also turning on "smart genes," supporting emotional stability, and staving off depression and dementia. Even a single hour of exercise can make you smarter by some measures through its effects on the brain. Movement prevents brain atrophy. Regular physical activity promotes good sleep, helps achieve and maintain ideal weight, and reduces the risk of cognitive decline. Studies show that people with high blood sugar - whether diabetic or not - have a faster rate of cognitive decline than those with normal blood sugar. Exercise helps manage blood sugar levels, thereby protecting brain health. Additionally, exercise increases the production of brain-derived neurotrophic factor (BDNF), a protein that helps protect and strengthen neural connections while spurring new brain cell growth. Benefits of exercise on brain health: Improves memory and thinking skills Reduces risk of cognitive decline by up to 50% Increases brain volume in areas critical for memory Enhances mood and reduces stress Improves sleep quality Boosts production of new brain cells
