Salt, the Brain, and Blood Pressure: How Glial “Gardeners” Drive Hypertension in Los Angeles
Key Takeaways for Los Angeles Residents
- Brain-Blood Pressure Connection: Salt triggers brain inflammation that raises blood pressure through neural pathways
- ⅔ of People Over 60: Living with hypertension in the U.S., many in Los Angeles County
- ⅓ Don’t Respond: To standard blood pressure medications—brain-based approaches may help
- Neurofeedback Solution: LENS therapy in Marina del Rey helps regulate nervous system and stress-reactive blood pressure
Understanding Your Brain’s Hidden Role in Blood Pressure
When we discuss the brain with clients at our Los Angeles neurofeedback center, most picture neurons—those fast-firing messengers passing electrical signals. But neurons don’t work alone. They’re supported by glial cells: astrocytes that buffer neurotransmitters and energy, and microglia—the immune-like “gardeners” that prune and maintain neural networks.
This partnership between neurons and glia is precisely what LENS neurofeedback therapy helps optimize. When this delicate balance is disrupted—as new research shows happens with high salt intake—brain circuits can tip toward overexcitability, hormonal surges, and surprisingly, higher blood pressure.
Groundbreaking McGill Study: Salt’s Direct Path to Your Brain
The Discovery That Changes Everything
A breakthrough study from McGill University (published September 2025) reveals something remarkable for those of us treating nervous system dysregulation in Beverly Hills, Santa Monica, and West Los Angeles. Researchers found that feeding rats a 2% salt solution—designed to mirror the processed, salty diets common in Los Angeles—sparked inflammation in a hypothalamic circuit that directly regulates blood pressure.
Here’s what happened in the brain:
- Microglia clustered around vasopressin-producing neurons
- These immune cells pruned back astrocyte branches
- Neurons became more excitable without their support system
- Extra neuronal “drive” boosted vasopressin release
- Blood pressure increased as a direct result
When researchers blocked the microglial pruning, both neuronal activity and hypertension subsided—proving the brain’s central role in salt-induced blood pressure changes.
Why This Matters for Los Angeles County’s 2+ Million Hypertension Patients
McGill’s research has profound implications for Southern California residents. Consider these statistics:
- ~⅔ of people over 60 live with hypertension—that’s hundreds of thousands in LA County alone
- ~⅓ don’t respond well to standard kidney/vascular-targeted medications
- Los Angeles has one of the highest rates of processed food consumption in California
If part of the problem originates in the brain, we need brain-acting interventions—treatments that calm neuroinflammation or rebalance neuron-glia interactions. This is exactly what LENS neurofeedback therapy accomplishes.
How Salt “Reaches” Your Brain: The Science Behind the Headlines
At MYNeuroBalance, we’ve observed how dietary factors affect brain wave patterns in our clients from Marina del Rey to Manhattan Beach. This new research provides the mechanism:
The Salt-Brain-Blood Pressure Pathway:
- High dietary salt alters cerebrospinal fluid sodium levels
- Microglia activate in response to sodium changes
- Astrocyte pruning removes neural support structures
- Glutamate spillover occurs without proper buffering
- NMDA receptors activate excessively
- Vasopressin surges from overstimulated neurons
- Blood pressure rises through hormonal pathways
This cellular “play-by-play” explains why our anxiety and stress clients often show improvements in blood pressure after neurofeedback training.
What MYNeuroBalance Clients Need to Know About Brain-Based Hypertension
Real-Life Applications for Los Angeles Residents:
1. Diet Still Matters—Especially in LA’s Food Scene
This study doesn’t replace kidney/vascular factors; it adds a crucial brain pathway. With Los Angeles’s abundance of restaurants and processed food options, cutting back on salt remains foundational. The rat model used 2% NaCl to emulate typical American processed food consumption.
2. Your Brain Is in the Blood Pressure Loop
For our clients with stress-reactive blood pressure from high-stress jobs in downtown LA or the entertainment industry, this research explains why nervous-system regulation through LENS neurofeedback complements medical care so effectively.
3. Hope for Treatment-Resistant Cases
While these findings are from animal studies, they point to microglia/astrocyte targets that might one day aid treatment-resistant hypertension. At MYNeuroBalance, we’re already seeing success using neurofeedback to address the brain component of blood pressure regulation.
How LENS Neurofeedback Addresses Brain-Based Blood Pressure Issues
At our Los Angeles neurofeedback center, we use the Low Energy Neurofeedback System (LENS) to help regulate the very brain circuits affected by salt-induced inflammation:
Our Approach:
- Brain Wave Analysis: We identify dysregulated patterns in the hypothalamic-pituitary axis
- Gentle Stimulation: LENS provides low-energy feedback to calm overactive neural circuits
- Glial Support: By reducing neuroinflammation, we help restore healthy neuron-glia balance
- Stress Reduction: Calming sympathetic drive naturally supports blood pressure regulation
Jon S. Haupers, certified directly by LENS creator Dr. Len Ochs, has helped hundreds of Los Angeles residents with stress-related health issues since 2012.
Success Stories from Los Angeles: Neurofeedback and Blood Pressure
While we don’t treat hypertension directly, many clients report blood pressure improvements as a secondary benefit of neurofeedback therapy. Our 90% success rate reflects the brain’s remarkable ability to self-regulate when given proper support.
Clients from Culver City, Venice, Redondo Beach, and throughout the South Bay have experienced:
- Reduced stress-reactive blood pressure spikes
- Better response to blood pressure medications
- Improved sleep quality (crucial for blood pressure regulation)
- Enhanced stress management capabilities

Frequently Asked Questions About Salt, Brain, and Blood Pressure
Q: How quickly does salt affect brain inflammation?
A: Research suggests brain changes can occur within weeks of high salt consumption. At MYNeuroBalance, we often see improvements in nervous system regulation within 10-20 neurofeedback sessions as inflammation decreases.
Q: Can neurofeedback replace blood pressure medication?
A: No, neurofeedback complements but doesn’t replace medical treatment. However, by addressing the brain component of hypertension, many clients find their medications work more effectively. Always consult your physician before changing medications.
Q: Why do some people’s blood pressure not respond to diet changes alone?
A: This research shows that once brain inflammation patterns are established, they may persist even with dietary improvements. LENS neurofeedback can help reset these patterns, making dietary changes more effective.
Q: Is the brain-blood pressure connection relevant for young people too?
A: Yes, especially in high-stress environments like Los Angeles. Young professionals, entertainment industry workers, and students can all benefit from nervous system regulation through neurofeedback.
The Science Behind LENS Neurofeedback and Vascular Health
Understanding how LENS neurofeedback supports vascular health requires examining the autonomic nervous system. Our PTSD and trauma clients often present with dysregulated sympathetic responses that directly impact blood pressure.
The hypothalamic-pituitary-adrenal (HPA) axis—the same system affected by salt-induced microglial activation—is precisely what LENS therapy helps regulate. By providing gentle electromagnetic feedback, we help the brain recognize and correct dysfunctional patterns.
Important Considerations for Los Angeles Residents
Research Caveats:
- Animal Model: While translational, human studies are still needed
- Scope: The study focuses on hypothalamic vasopressin pathways; other hypertension types may use different routes
- Individual Variation: Response to both salt and neurofeedback varies by person
When to Seek Help:
- Blood pressure remains high despite medication
- Stress significantly affects your readings
- You want to complement medical treatment with brain-based approaches
- Family history of hypertension or stroke
Conclusion: A New Understanding of Hypertension for Los Angeles
This groundbreaking research reminds us that high blood pressure isn’t just about the heart and kidneys—it’s also about the brain and how our neurons and glial cells respond to stressors like salt. By understanding this hidden connection, we can see why lifestyle changes combined with nervous system regulation through LENS neurofeedback therapy may be as important as medication for many people.
While the McGill findings are still in early stages, they validate what we’ve observed at MYNeuroBalance for over a decade: the brain is not just a passenger but an active driver in cardiovascular health. For the millions of Los Angeles residents dealing with hypertension—especially those not responding to traditional treatment—addressing the brain component through neurofeedback offers new hope.
