The optimal way to stimulate the brain is through social interaction, according to Dr. Douglas Scharre, a neurologist at The Ohio State University College of Medicine. He asserts that while activities like reading, puzzles, and art are beneficial, engaging in conversations provides a more comprehensive workout for the brain.
"Use it or lose it" is the principle guiding brain health, Scharre explained in an interview. The brain requires continuous stimulation to establish and maintain neural connections. A robust "cognitive reserve," characterized by a dense network of healthy brain cells, offers protection against cognitive decline and dementia. Socialization, Scharre notes, actively engages multiple brain functions simultaneously. When interacting with others, individuals process facial expressions, analyze reactions, listen to and comprehend information, recall memories for storytelling, and engage in rapid-fire responses and judgments.

While socialization takes precedence, Scharre still recommends various activities to keep the brain stimulated, including games, reading, artistic endeavors, music, sports, and learning new languages. He also advises reducing passive stimulation, such as excessive television watching and scrolling through phones, as these activities can hinder the brain's need for active engagement.
A recent survey from Ohio State University revealed that 60% of Americans wish to prioritize brain health earlier in life but lack guidance on how to do so. Scharre suggests that the best time to begin focusing on brain health is at any age, though middle age or younger presents an ideal window for establishing a strong cognitive reserve that can delay the onset of memory issues.
Beyond mental stimulation, Scharre outlined several other critical components of brain health:
Sleep Quality
Ensuring sufficient, quality sleep is paramount for removing toxins from the brain. Scharre recommends turning off lights and televisions, addressing sleep apnea, and maintaining consistent sleep routines.
Metabolic Health
Managing conditions such as high blood pressure, diabetes, and elevated cholesterol is crucial. These metabolic factors can impede blood flow to the brain by clogging blood vessels.
Stress and Depression Management
Mental well-being significantly impacts brain function. Depression can disrupt neural communication and lead to a loss of brain cell connections. Chronic stress can impair focus, decision-making, and emotional regulation.
Nutrition
The brain requires essential vitamins that it cannot produce internally. Scharre advocates for a Mediterranean diet, rich in fruits, vegetables, and vegetable oils, while limiting red meat and processed sugars.
Physical Activity
All forms of physical exercise benefit the brain. Scharre specifically recommends a combination of aerobic, strength, flexibility, and balance exercises to stimulate different brain regions and build a more robust cognitive reserve.

To monitor his own brain health, Scharre practices tracking various health metrics, including diet, sleep, exercise, cognitive activities, socialization, blood pressure, and laboratory results. This approach can help identify areas needing improvement and detect potential issues early.
