The Science of Brain Health

Your brain is remarkably adaptable. Through a process called neuroplasticity, it can form new connections, strengthen existing ones, and even generate new neurons throughout your entire life.

Key Pillars of Brain Health

Research has identified several modifiable factors that significantly impact cognitive function and dementia risk:

Physical Activity

Regular exercise is one of the most powerful interventions for brain health. It increases blood flow to the brain, promotes the release of brain-derived neurotrophic factor (BDNF), and supports the growth of new brain cells in the hippocampus.

Sleep Quality

During sleep, your brain clears toxic proteins and consolidates memories. Poor sleep is increasingly recognized as a risk factor for cognitive decline and Alzheimer's disease.

Cognitive Engagement

Mental stimulation through learning new skills, reading, puzzles, and social interaction helps build cognitive reserve—a buffer that can delay the onset of dementia symptoms.

Nutrition

A Mediterranean-style diet rich in vegetables, fruits, whole grains, fish, and healthy fats has been consistently associated with better cognitive outcomes.

Taking Action

The good news is that it's never too late to start protecting your brain. Even small changes in lifestyle can have meaningful effects on cognitive health over time.
