Cognitive Reserve: The Hidden Key to a Healthy Brain

Discover the secret to optimal brain health with Jennifer Bramen, PhD, Senior Research Scientist at Pacific Neuroscience Institute®. Learn how cognitive reserve protects against cognitive decline and neurodegenerative conditions, and gain practical advice to enhance your brain health.

In this in-depth interview, we had the privilege of speaking with Jennifer Bramen, PhD, Senior Research Scientist at Pacific Neuroscience Institute. As an expert in cognitive neuroscience and brain health, Dr. Bramen thoroughly comprehends how cognitive reserve protects against age-related cognitive changes and neurodegenerative conditions. Continue reading to explore the science behind cognitive reserve and gain expert advice on enhancing your brain health.  

What is Cognitive Reserve?

According to Dr. Bramen,”cognitive reserve refers to an individual’s ability to maintain cognitive and functional abilities despite the presence of neurodegeneration due to pathology or normal aging.” Cognitive reserve enables the brain to adjust and compensate for the challenges it faces. Thus, cognitive reserve plays a vital role in protecting the brain against cognitive decline and age-related cognitive disorders. 

How does cognitive reserve protect your brain health? 

Cognitive reserve relies on the remarkable principle of neuroplasticity. Neuroplasticity encompasses the brain’s ability to adapt and react to various stimuli from the environment, new experiences, and other developmental mechanisms. This intricate phenomenon involves a diverse array of complex cellular and molecular processes, facilitating the establishment of new neural connections. 

By utilizing new neural pathways or adopting alternative strategies, neuroplasticity allows individuals to effectively adapt to neurodegeneration due to normal aging or cognitive decline. Therefore, neuroplasticity serves as a powerful tool in augmenting cognitive reserve and protecting brain health. 

Although genetic factors play a role in these processes, there are various actions you can take to optimize your cognitive reserve.  

4 Steps to Strengthen Your Cognitive Reserve

1. Intellectual Stimulation

Dr. Bramen recommends engaging in activities that promote intellectual stimulation. “Learning new things is essential,” Dr. Bramen emphasizes. “It’s easy to stick to what we already do well, but the old saying holds true: ‘Use it or lose it.‘” Dr. Bramen personally suggests acquiring a new skill each year. Furthermore, enhancing organizational skills can help compensate for memory loss, which is common in both normal aging and cognitive decline.  

Don’t know where to start? Try learning a new language, starting a fun hobby, or organizing that messy closet you’ve been avoiding for years. Regardless of how you approach it, engaging in intellectual engagement is vital for sustaining optimal cognition. 

2. Physical Wellness

Did you know that your physical health directly impacts your cognitive reserve? Consistent exercise, proper nutrition, and quality sleep are essential for preserving brain health.

Exercise boosts blood flow to the brain, enhances neuroplasticity, and improves cognitive abilities such as attention, memory, and executive function. Dr. Bramen notes, “regular physical exercise has consistently been associated with better cognitive function and a reduced risk of cognitive decline.” She recommends participating in consistent aerobic exercise (e.g., brisk walking, jogging, cycling) for at least 150 minutes per week, coupled with two sessions of strength training exercises every week.  

Regarding nutrition, Dr. Bramen advises maintaining a well-balanced diet rich in fiber and healthy fats. Additionally, managing cardiovascular and diabetic risk factors through dietary choices is crucial for optimizing brain health.  

Sleep is another significant factor for brain wellness. “Quality sleep is essential for cognitive function and memory consolidation,” states Dr. Bramen. During sleep, the brain clears out waste products, processes information, and restores energy. Chronic sleep deprivation or poor sleep quality can impair cognitive performance, attention, and memory. Dr. Bramen recommends aiming for 7-9 hours of quality sleep per night to support optimal brain function. 

3. Social Engagement

Social engagement plays a significant role in maintaining cognitive reserve and brain health. Dr. Bramen explains that “regular social interactions, involvement in community organizations aligned with personal interests, and participating in group exercise classes” hold particular advantages.  

The key lies in selecting activities that personally motivate you and integrating them into your daily life. Conversely, social disengagement or isolation increases the risk of cognitive impairment, emphasizing the importance of nurturing social connections. 

4. Cognitive Education
