The Brain’s Power to Change

Understanding Neuroplasticity and How to Strengthen It

Imagine waking up one day and realizing that your brain is not as static as you once believed. What if I told you that your brain is constantly reshaping itself in response to everything you do, every experience you have, and even how you think? This ability of the brain to reorganize itself is called neuroplasticity, and it’s one of the most exciting discoveries in neuroscience over the past century. Whether you’re learning a new language, recovering from trauma, or simply trying to maintain a sharp mind as you age, neuroplasticity is at the core of how we adapt and thrive.

But what exactly is neuroplasticity, and how can we harness it to keep our brains healthy?

What Is Neuroplasticity?

Neuroplasticity refers to the brain’s incredible ability to reorganize itself by forming new neural connections. Essentially, your brain can “rewire” itself based on your experiences, thoughts, and actions. This is particularly important when it comes to recovering from injury, learning new skills, or even adjusting to life changes. The concept was first proposed by neuroscientist Santiago Ramón y Cajal in the late 19th century, though it wasn’t until the mid-20th century that the term neuroplasticity gained recognition, largely through the work of Canadian psychologist Donald Hebb and later, American neuroscientist Michael Merzenich.

For many years, it was believed that the brain stopped changing after childhood, meaning that once we reached adulthood, our neural pathways were set. But groundbreaking research in the 1960s and 1970s disproved this. Neuroplasticity shows that the brain can keep evolving throughout life, allowing it to adapt, learn, and heal.

The Role of Neuroplasticity in a Healthy Brain

Neuroplasticity is essential for the healthy functioning of the brain. It’s the mechanism that allows us to learn new things, recover from brain injuries, and adapt to changes in our environment. It is also at the heart of how therapies like neurofeedback and cognitive behavioral therapy work, reshaping neural pathways to promote healing and better functioning.

Imagine your brain as a city with roads and highways. Some roads are well-traveled, others less so. When you learn something new or break an old habit, it’s like building a new road or updating an old one. This continuous process is neuroplasticity in action, ensuring that your brain remains flexible, resilient, and capable of learning and adapting, no matter your age.

Cognitive Reserve and Alzheimer’s Disease

An important concept related to neuroplasticity is cognitive reserve, which refers to the brain’s ability to cope with damage by utilizing existing neural networks or forming new ones. People with higher cognitive reserve are better equipped to handle brain changes that come with aging, injury, or diseases like Alzheimer’s. Unfortunately, Alzheimer’s impairs neuroplasticity, making it harder for the brain to form new connections and compensate for the loss of function.

Studies show that while neuroplasticity cannot cure Alzheimer’s, it can help slow the progression of cognitive decline. Cognitive reserve, built up through years of learning, social engagement, and mental activity, acts like a buffer. This explains why some people with significant Alzheimer’s pathology can still function relatively well.

How to Maximize Neuroplasticity and Build Cognitive Reserve

The great news is that there are ways to actively encourage neuroplasticity throughout your life, keeping your brain healthier for longer. Here are some strategies backed by science:

1. Learning New Skills: Whether it’s picking up a new language, learning to play an instrument, or even trying out a new hobby, challenging your brain strengthens your neural networks. Studies show that lifelong learning is one of the best ways to increase cognitive reserve.

2. Cognitive Behavioral Therapy (CBT): CBT is not just about changing thought patterns—it’s about reshaping the brain. By working on specific cognitive distortions, CBT promotes neuroplasticity, helping individuals with anxiety, depression, and trauma recover by building healthier neural pathways.

3. Neurofeedback: This powerful tool taps into neuroplasticity by helping your brain regulate itself. Through feedback, the brain learns to balance its own activity, strengthening underactive areas and calming down overactive regions. Neurofeedback is very effective in treating issues like ADHD, anxiety, and PTSD. LENS neurofeedback in particular, works to free the brain from it’s chronic frequency patterns that it gets stuck in due to trauma and stress. These maladaptive patterns over time, remain in a state of “neural gridlock”, that LENS seems to be able to dislodge from and into a more flexible one, that creates greater neuroplasticity.

4. Sleep: Sleep plays a vital role in consolidating memories and promoting neuroplasticity. During sleep, the brain processes information and strengthens the neural connections made throughout the day. Poor sleep, on the other hand, can impair neuroplasticity and cognitive function.

5. Physical Activity: Exercise is a major driver of neuroplasticity. Aerobic exercise, in particular, increases the production of brain-derived neurotrophic factor (BDNF), which supports the growth of new neurons and synapses. Regular physical activity also improves blood flow to the brain, helping to keep it in optimal shape.

6. Mind-Body Practices: Practices like yoga, Tai Chi, and mindful meditation have been shown to enhance neuroplasticity by reducing stress and increasing awareness. These activities encourage the brain to remain flexible and adaptable, promoting both mental and emotional resilience.

7. Brain Training: Games and apps designed to stimulate cognitive function can also help. While not all brain training programs are equally effective, research supports the idea that engaging in mentally stimulating activities can promote neuroplasticity and cognitive health.

8. Mindful Meditation: Regular meditation has been proven to increase the brain’s grey matter and strengthen areas associated with memory, self-awareness, and emotional regulation. These changes are evidence of neuroplasticity in action, and they contribute to an overall healthier brain.

Neuroplasticity as a Tool for Slowing Cognitive Decline

For those concerned about cognitive decline, especially in relation to diseases like Alzheimer’s, neuroplasticity offers a beacon of hope. By actively working to maintain a healthy brain through the strategies mentioned above, you can enhance your cognitive reserve and potentially slow the onset or progression of symptoms.

While there is no cure for Alzheimer’s, there is growing evidence that building neuroplasticity throughout life may help delay the worst effects. Engaging in continuous learning, maintaining social connections, practicing mindfulness, and keeping the body active are key to preserving brain health well into later years.

Conclusion: Start Building Your Brain’s Strength Today

The concept of neuroplasticity shows that the brain is a living, breathing organ capable of change. Whether you’re in your twenties or seventies, your brain can continue to evolve. And while conditions like Alzheimer’s may affect how well this process works, there’s much you can do to strengthen it.

From picking up new hobbies to practicing mindfulness, prioritizing sleep, and incorporating neurofeedback into your routine, there are plenty of ways to encourage your brain’s plasticity. The best part? It’s never too late to start. By making intentional changes now, you’re investing in your cognitive future—one new neural connection at a time.
