Exploring the Critical Link Between Neuroinflammation and Cognitive Decline — Part 1

By Boris Prilutsky

In principle, his understanding was that, following post-traumatic neuroinflammation, the demand for blood supply to support healing and recuperation increased. However, tension within the neck and upper back musculature decreased the necessary blood supply.

Insufficient cerebrospinal fluid drainage and venous blood drainage were fueling brain inflammation. Autonomic irregularity was an established biomarker for diagnosing concussion, while the progress of brain function was also assessed by improvement of autonomic nervous system activities as well as by evaluating cognitive activities.

For more than 30 years of my career practicing medical and sports massage, in the United States of America, I successfully addressed many cases of concussions, restoring brain function and, most importantly, preventing posttraumatic degenerative brain disease.

It is important to note that, while working with Olympian teams, Olympian athletes exposed to chronic stress, including excessive stress hormones secretion, some used to develop similar conditions involving tension within cervical muscles, insufficient brain fluid drainage, and brain inflammation.

In our protocol to address Olympian athletes' burnout and overtraining, we adopted many of the post-concussion rehabilitation concepts.

Again, post-traumatic brain conditions and chronic stress-related disorders trigger neuroinflammation, and if these conditions are not addressed in a timely and appropriate manner, patients have a high risk of developing dementias.

In my past writings and video presentations, I clearly demonstrated through hands-on explanations massage protocols and their multiple goals, mainly to achieve a significant anti-inflammatory effect on the brain.

The objective is to restore adequate cerebral perfusion. Yes, we use multiple techniques to accelerate cerebrospinal fluid drainage and balance autonomic activities, but the bottom line is to restore adequate blood supply to the brain as a main anti-inflammatory effort.

Critical Link Between Neuroinflammation and Cognitive Decline

For decades in the US, there has been a search for a cure for dementia. Notably, the focus has been on the most visible culprits found in the brains of patients post-mortem: the sticky amyloid-beta plaques and twisted tau tangles.

In the traditional narrative of Alzheimer’s disease and related dementias, these abnormal protein aggregations were cast as the primary instigators of cognitive ruin.

However, a profound paradigm shift is underway in neuroscience. Emerging research increasingly demonstrates that these proteins, while undeniably toxic, do not act in a vacuum. Instead, chronic brain inflammation—neuroinflammation—is the critical, underlying precondition that bridges the gap between early cellular stress and the devastating onset of clinical dementia.

The Brain's Unique Immune System

Prof. Alexander Dembo always stressed the importance:

"To understand why inflammation is a prerequisite for dementia, one must first understand the brain’s unique immune system. Unlike the rest of the body, which relies on a complex network of white blood cells, the central nervous system depends heavily on a single population of resident immune cells called microglia. In a healthy brain, microglia act as diligent custodians. They constantly patrol the neural environment, clearing away cellular debris, pruning weak synapses, and neutralizing potential threats.

When a minor injury or infection occurs, microglia initiate a localized, temporary inflammatory response to repair the damage. This acute inflammation is beneficial, self-limiting, and essential for brain health.

The problem arises when this protective mechanism becomes hijacked. At the time of head trauma or chronic systemic infections, or chronic stress explosion, the brain’s immune response loses its agility. Instead of turning off after the threat is neutralized, microglia remain perpetually activated, locked in a state of chronic, low-grade inflammation. This sustained neuroinflammation alters the chemical landscape of the brain, transforming a supportive microenvironment into a hostile, toxic one.

Crucially, this inflammatory shift happens long before a patient experiences their first bout of memory loss. Advanced neuroimaging and biomarker studies reveal that neuroinflammation is present years, sometimes even decades, before the clinical threshold of dementia is crossed. It acts as the necessary soil in which the seeds of neurodegeneration take root.

Without the pervasive influence of inflammation, the brain can often tolerate a remarkable amount of amyloid and tau pathology. Indeed, autopsy studies occasionally reveal individuals who passed away with brains laden with plaques but who never showed signs of cognitive decline during their lives. What separated these resilient individuals from dementia sufferers was often the absence of rampant neuroinflammation.

When chronic inflammation is established, it triggers a catastrophic domino effect. Persistent inflammatory signaling compromises the blood-brain barrier, a strict checkpoint that normally protects the brain from harmful toxins in the bloodstream. As this barrier weakens, peripheral inflammatory molecules and pathogens leak into the brain, further fueling the fire.

Concurrently, the hyper-activated microglia stop acting as caretakers. Overwhelmed by the constant state of alarm, they begin to mistakenly destroy healthy synapses—the vital connections that allow neurons to communicate.

Furthermore, neuroinflammation acts as a powerful accelerant for protein pathology. The inflammatory cytokines released by stressed microglia actively stimulate the enzymes responsible for producing amyloid-beta and destabilizing tau proteins. This creates a vicious, self-perpetuating cycle: amyloid plaques trigger an inflammatory response, and that very inflammation drives the production of more plaques while accelerating the spread of tau tangles across the brain's memory networks.

Recognizing neuroinflammation as a foundational precondition completely redefines how we must approach dementia prevention and treatment. Rather than waiting for irreversible structural damage and cognitive deficits to manifest, therapeutic interventions must target the immune system early.

Lifestyle modifications—such as regular medical massage protocols specifically designed for cases of chronic stress-related disorders, addressing tension within the neck, upper back, and respiratory muscles, restoring normal and sufficient drainage of cerebrospinal fluid as well as restoring blood supply to the brain, and creating conditions for restorative sleep—are not just vague wellness advice; they are direct interventions that quiet microglial activation and preserve the blood-brain barrier.

Ultimately, dementia development is not the result of a single, isolated biological mistake. It is the consequence of a system pushed beyond its capacity to heal.

By reframing neuroinflammation not as a mere side effect of neurodegeneration, but as its essential fuel and primary driver, science is unlocking a more hopeful frontier. Dampening the fires of chronic brain inflammation before they consume our neural networks represents our best chance at halting the dementia epidemic at its very source."

Conclusion

This article discusses a critical public health issue and was not written for submission to professional publications. Rather, it should be viewed as a scientifically grounded overview based on extensive clinical experience.

I would like to declare that, in preparing this overview, I used literature from my old country. Having said that, I believe I could search for and provide many references related to research conducted in the United States that would support every claim I made in this overview.

As professionals, we all grew up learning the fundamentals of medical physiology.

Having said it, lately, the FDA has been requiring patient-reported outcomes; otherwise, the agency will not approve a product, because research reproducibility remains a significant concern.

A 2016 Nature survey of 1,576 researchers found that more than 70% had been unable to reproduce another researcher's experiments, while more than half had experienced difficulty reproducing their own findings.

Many times, professionals base their arguments in discussion on data that cannot be reproduced.

I welcome disagreement, but the entire discussion has to be based on clinical experience and not on research data alone. Just to avoid repeating myself, I have clearly stressed my point throughout this article.

If there is room for agreement and disagreement, these topics will be addressed in my 15-minute video presentation. Link below.

I was inspired to write this overview because I was constantly challenged whenever I suggested that improving cerebral perfusion may contribute to the regulation of neuroinflammatory processes and support the brain's ability to maintain its normal physiological functions.

Meanwhile, you are welcome to share your agreements or disagreements and ask questions.
