Can the brain recover from MS damage? What neuroplasticity tells us

Multiple sclerosis (MS) is a chronic condition where the immune system mistakenly attacks the protective covering of nerves in the brain and spinal cord. This damage disrupts how signals are sent and received, leading to a wide range of symptoms like fatigue, weakness, and memory issues.

What is neuroplasticity, and how does it help in MS?

Neuroplasticity is the brain’s built-in ability to change, adapt, and reorganize itself. When one pathway gets blocked, like by a lesion caused by MS, the brain tries to find a different route to carry out the same function. Imagine your usual road to the supermarket is closed. Instead of giving up, you find a side street or a detour. That’s how your brain adapts, by rerouting information through new or less-used neural pathways.

In MS, the immune system damages the myelin sheath that protects nerve fibers. This damage disrupts communication between the brain and the body. Neuroplasticity doesn’t reverse the damage, but it helps the brain work around it.

This reorganization can support everything from muscle control to memory. It’s one reason why some people regain movement after a relapse or continue to function well despite visible lesions on MRI scans.

How do we know neuroplasticity works in MS?

Brain imaging provides the evidence

Researchers use functional MRI (fMRI) to track brain activity during tasks. In people with MS, these scans often show that after a relapse or intensive therapy, different brain regions “light up” when performing tasks, suggesting the brain is using new pathways.

For example, after an MS-related vision problem like optic neuritis, people may activate not just their visual cortex but also decision-making areas of the brain. This adaptation helps them process visual information in a new way.

Plasticity can be helpful, or not

Neuroplasticity isn't always positive. In some cases, the brain may develop “maladaptive” patterns, new connections that actually reinforce fatigue, spasticity, or poor posture. This can limit recovery.

Understanding this balance helps doctors and therapists guide patients toward adaptive plasticity that improves function and avoids long-term dysfunction.

How does rehabilitation help rewire the brain?

Therapy fuels recovery

Rehabilitation is more than just repeating movements, it’s about training the brain to learn new patterns. This can include:

• Physical therapy: to improve balance, strength, and gait
• Cognitive therapy: to sharpen attention, memory, and problem-solving
• Speech and occupational therapy: to support communication and daily function

Each of these therapies encourages the brain to reorganize itself in useful ways.

High-tech tools offer new hope

Recent studies show promising results with technologies like virtual reality (VR), augmented reality (AR), and tele-rehabilitation. These systems simulate real-world activities, challenging the brain in safe, immersive ways.

Patients using VR balance boards or interactive games have shown improved coordination and measurable changes in brain activity, proof that neuroplasticity is being activated.

Which factors support or limit neuroplasticity?

Limits to brain adaptation

Neuroplasticity isn’t unlimited. Several things can reduce the brain’s ability to reorganize:

• Disease progression: In progressive MS, plasticity potential declines as damage accumulates.
• Inflammation: Active inflammation can interfere with signaling.
• Aging and fatigue: The brain's flexibility tends to decline with age and chronic exhaustion.
• Brain reserve: People with more robust initial brain function may adapt more easily than those with less reserve.

This explains why two people with similar MRI findings might experience different levels of disability or recovery.

Early intervention makes a difference

The sooner rehab or cognitive training begins after a relapse, the more likely it is to help. Repeated relapses or long delays can reduce the brain's plasticity over time.

That's why neurologists increasingly emphasize early rehab alongside disease-modifying treatments.

Can you boost your brain’s plasticity? Yes, here’s how.

Neuroplasticity isn’t just something that happens passively, it’s something you can actively support through your daily habits. Just like building strength in a muscle, your brain benefits from consistent and varied stimulation. Here's how you can help nurture your brain’s flexibility, naturally and safely:

Keep your mind active

Challenging your brain with new and engaging tasks can help stimulate neural growth. Reading, solving puzzles, learning a new language or instrument, and even engaging in creative hobbies like painting or writing can keep your brain circuits firing. These activities promote the formation of new synapses and help maintain cognitive health over time.

Move your body regularly

Physical activity doesn’t just benefit your muscles, it boosts brain function too. Even light forms of exercise, like walking, stretching, or gentle resistance training, have been shown to support neuroplasticity by increasing blood flow to the brain, which promotes neuron growth and survival. Consistency is key, even if your energy levels or mobility are limited.

Fuel your brain with healthy foods

Your brain thrives on nutrients, particularly those that reduce inflammation and support cell repair. Diets rich in omega-3 fatty acids (found in fish, flaxseeds, and walnuts), leafy green vegetables, berries, and whole grains provide essential building blocks for healthy brain function. A balanced, anti-inflammatory diet can also help reduce oxidative stress, which may otherwise interfere with the brain’s adaptive processes.

Prioritize quality sleep

Sleep is when the brain processes new experiences, repairs itself, and consolidates memories. Aim for seven to nine hours of restful sleep per night. Poor sleep disrupts learning and memory and may limit your brain’s ability to rewire effectively. Creating a calming bedtime routine and keeping a consistent sleep schedule can help you get the rest your brain needs to stay adaptable.

Manage stress in healthy ways

Chronic stress can impair neuroplasticity, especially in areas of the brain responsible for memory and learning. Finding healthy ways to manage emotional stress is just as important as physical health. Practices like mindfulness, meditation, journaling, and connecting with supportive people can reduce the negative impact of stress hormones on the brain. Speaking with a mental health professional can also provide tailored strategies to build emotional resilience.

Taking small, daily steps to support your brain’s health doesn’t just protect your cognitive function, it can actively strengthen the brain’s ability to adapt, recover, and thrive, even in the face of challenges like MS.

What's next in neuroplasticity research?

Scientists are actively exploring new ways to enhance the brain’s ability to rewire itself in people with MS. One area of focus is boosting levels of brain-derived neurotrophic factor (BDNF), a naturally occurring protein that supports the growth and survival of neurons. Another promising approach is non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS), which aim to activate specific regions of the brain to encourage functional reorganization. Researchers are also looking at how combining cognitive and motor rehabilitation may lead to more effective, whole-brain adaptation.

While these emerging therapies are still being studied and are not yet part of standard MS treatment, they represent exciting possibilities for the future.

Key takeaways

Neuroplasticity is the brain’s natural ability to adapt by forming new connections, and it plays a vital role in helping people with MS recover or maintain function. While it can’t reverse the damage caused by MS, it allows the brain to work around injured areas, supporting skills like movement, memory, and coordination. Rehabilitation therapies and daily habits, such as mental stimulation, regular physical activity, good nutrition, sleep, and stress management, can all help promote healthy brain adaptation. Although neuroplasticity has its limits, especially as MS progresses, early intervention and emerging treatments offer real hope for improving quality of life.
