1. Your brain is plastic: It can change and adapt throughout your entire life

The brain's machinery is being continuously rewired and functionally revised, substantially under your control, throughout the course of your natural life.

Neuroplasticity is lifelong. The brain's ability to change and adapt, known as neuroplasticity, doesn't stop after childhood. It continues throughout adulthood and into old age. This means that regardless of your age, you have the potential to improve your cognitive abilities, learn new skills, and recover from brain injuries or disorders.

Change is driven by experience. Your brain's structure and function are shaped by your experiences, thoughts, and actions. Every time you learn something new, practice a skill, or have a novel experience, your brain undergoes physical changes. Neurons form new connections, strengthen existing ones, or prune away unused pathways. This ongoing process of rewiring is the basis for learning, memory, and adaptation.

You have control. While some brain changes occur naturally with age, you have significant control over your brain's plasticity. By engaging in challenging mental activities, maintaining a healthy lifestyle, and staying socially active, you can promote positive brain changes and potentially counteract age-related decline.

2. Brain plasticity underlies both cognitive decline and potential improvement

Every moment of learning provides a moment of opportunity for the brain to stabilize—and reduce the disruptive power of—potentially interfering backgrounds or "noise."

Plasticity is a double-edged sword. The same mechanisms that allow for learning and improvement can also lead to cognitive decline if not properly engaged. When the brain isn't challenged or is consistently exposed to negative stimuli, it can rewire itself in ways that reinforce decline.

Cognitive decline is not inevitable. While some degree of cognitive slowing is common with age, severe decline is not an inevitable part of aging. Many of the changes associated with cognitive decline are the result of disuse or negative plasticity, rather than irreversible biological aging.

Improvement is possible at any age. Because the brain remains plastic throughout life, there's always potential for improvement. Even individuals with significant cognitive decline or brain injuries can often make substantial gains through targeted brain training and lifestyle changes.

3. Everyday activities and habits significantly impact brain health

Your brain's plasticity is the main source of the refined skills and abilities that account for your capacities at any age in life.

Daily choices matter. The activities you engage in, the foods you eat, how much you sleep, and how you manage stress all have a cumulative effect on your brain health. These daily choices can either promote positive plasticity or contribute to decline.

Cognitive challenge is crucial. Engaging in mentally stimulating activities that push you out of your comfort zone is essential for maintaining and improving cognitive function. This could include learning a new language, mastering a musical instrument, or tackling complex problems at work.

Physical exercise benefits the brain. Regular physical activity not only improves overall health but also directly benefits brain function. Exercise increases blood flow to the brain, promotes the growth of new neurons, and enhances connectivity between brain regions.

4. Negative learning habits can accelerate cognitive decline

For many older individuals, those compensatory behaviors are designed to achieve what we perceive to be a great personal goal: An easier, more trouble-free older life.

Beware of compensatory behaviors. As we age, we often develop habits to compensate for perceived declines in ability. However, these behaviors can actually accelerate cognitive decline by reducing the brain's engagement and reinforcing limitations.

Avoid excessive reliance on technology. While technology can be helpful, over-reliance on devices like GPS for navigation or calculators for basic math can lead to atrophy of important cognitive skills.

Challenge negative self-talk. Repeatedly telling yourself "I can't" or "I'm too old for that" can become a self-fulfilling prophecy. Your brain responds to these messages, potentially reinforcing decline.

5. Brain training exercises can effectively rejuvenate cognitive abilities

We have collectively demonstrated that just about every aspect of our brain-power, intelligence, or control—in normal and in psychiatrically or neurologically impaired individuals—can be improved by intense, efficient, appropriately targeted behavioral training.

Targeted training works. Scientifically designed brain training exercises can effectively improve specific cognitive abilities, such as processing speed, memory, and attention. These improvements can translate to real-world benefits in daily life.

Efficiency is key. Well-designed brain training programs can achieve in minutes what might take days of natural experience to accomplish. They do this by precisely targeting specific brain functions and adapting to individual performance levels.

Generalization to real life is crucial. Effective brain training should not just improve performance on specific exercises but should generalize to improvements in everyday cognitive functioning and quality of life.

6. Social interaction and emotional well-being are crucial for brain health

Our happiness is inextricably tied to the nature and sophistication of our social interactions.

Social engagement stimulates the brain. Regular social interaction provides complex cognitive stimulation, emotional support, and a sense of purpose, all of which contribute to brain health.

Emotional well-being affects cognition. Chronic stress, anxiety, and depression can negatively impact brain function and plasticity. Conversely, positive emotions and a sense of well-being can enhance cognitive performance and promote brain health.

Cultivate meaningful relationships. Building and maintaining strong social connections is not just emotionally fulfilling but also cognitively beneficial. Engage in activities that promote social interaction and emotional support.

7. Maintaining brain health requires lifelong commitment and effort

You need to continue to work seriously at things that support its health now, and continue to work in ways that support your brain health out to the end of your time on Earth.

Brain health is a lifelong journey. Maintaining cognitive function and promoting positive plasticity is not a one-time effort but a continuous process that requires ongoing commitment and effort.

Balance is important. A brain-healthy lifestyle involves a combination of mental stimulation, physical exercise, social engagement, proper nutrition, and stress management. No single approach is sufficient on its own.

Persistence pays off. Consistent, long-term effort in maintaining brain health can yield significant benefits, potentially delaying or preventing cognitive decline and enhancing quality of life well into old age.
