What is Neuroinflammation, and How Can Functional Medicine Help to Identify and Reduce it?

If you've found yourself struggling with persistent headaches, brain fog, or even changes in mood, you may be more familiar with neuroinflammation than you think. Simply put, neuroinflammation is an inflammatory response within your brain or spinal cord. Just as you might experience inflammation in your joints or other parts of your body, your brain can also be affected!

Recognizing and addressing neuroinflammation is important not just for symptomatic relief but also for preserving your brain's longevity and optimal functionality. Unlike conventional medicine, which often focuses on treating symptoms, functional medicine aims to identify and tackle the root cause of your neuroinflammation. This approach allows for a more comprehensive understanding of how your condition may have developed and what can be done to manage or even reverse it.


What is Neuroinflammation?

Neuroinflammation is a response from your body's immune system that specifically targets the central nervous system, encompassing both your brain and spinal cord. While this inflammatory process naturally serves to protect you, it can lead to more serious health concerns if it becomes a lingering or chronic issue. This condition is often linked with serious diseases like Alzheimer's, Parkinson's, and Huntington's, but it's important to know that it can also occur on its own without a neurodegenerative disease being present. 

Various factors can trigger neuroinflammation—these include viral infections, autoimmune disorders, and even inflammation from other parts of your body like your gut, lungs, or skin. Situational stress, metabolic problems, heavy metals, and certain lifestyle choices can also be contributing factors. Recent research points out that chronic conditions like rheumatoid arthritis or lung disease can affect your brain's protective barrier and activate certain brain cells, known as glial cells, which can set off neuroinflammation.

When your body experiences neuroinflammation, you might notice a range of symptoms that fall under the umbrella term "sickness behavior." You could experience a decline in cognitive abilities, including memory and decision-making, or find yourself dealing with emotional challenges like anxiety or depression. Even physical symptoms, such as a feeling of constant fatigue, may occur. If not addressed, neuroinflammation has the potential to develop into serious neurological issues, like seizures, or lead to more enduring conditions, such as Gulf War Illness or chronic fatigue syndrome (20,25). 

What is the Role of Functional Medicine in Neuroinflammation?

Functional medicine offers a fresh perspective on treating neuroinflammation by focusing on the body as an integrated system. This holistic treatment for brain inflammation suggests that imbalances in one area of the body can impact brain health, leading us to think more broadly about causes and treatments. 

Instead of just easing symptoms, functional medicine aims to identify and address the underlying factors that contribute to neuroinflammation. The conclusion here is clear: by understanding the root causes, more effective and individualized treatment plans can be developed. This tailored approach not only targets the immediate issues but also offers long-term strategies for maintaining brain health.

Functional Medicine Lab Testing for Neuroinflammation

To better understand and address the complexities of neuroinflammation, functional medicine employs a range of specialized lab tests that look beyond typical health markers. 

C-Reactive Protein 

This C-Reactive Protein Test by Access Medical Laboratories measures the level of CRP, a protein that increases when there's systemic inflammation. Elevated levels could be an indicator of neuroinflammation.

Autoimmune Antibody Testing 

This Autoimmune Profile by Immunosciences Lab looks for the presence of autoantibodies that might indicate an autoimmune condition, which could be a triggering factor for neuroinflammation.


Since the gut is closely linked to systemic inflammation, tests like the GI-MAP by Diagnostic Solutions can provide information on gut flora imbalances or infections that might be impacting brain health.

Heavy Metal Testing 

Toxins such as mercury can contribute to inflammation and neurodegenerative diseases.

Array 20

This Array 20 Test by Cyrex Laboratories can assess the permeability of the blood-brain barrier, offering key insights into the condition of this important protective shield around the brain. When the blood-brain barrier is compromised, unwanted substances can enter the brain, potentially triggering or worsening neuroinflammation.

Understanding Lab Results 

Practitioners use lab tests for neuroinflammation, such as the Array 20 Panel, to shape the most effective treatment options for each individual. By interpreting neuroinflammation test results, they can identify which factors may be contributing to inflammation in the nervous system. This enables them to implement functional medicine testing for brain health strategy that addresses the underlying issues rather than merely treating the symptoms. This tailored approach ensures that each patient receives a personalized treatment plan best suited for their unique health profile.

Functional Medicine Strategies to Reduce Neuroinflammation

Functional medicine reduces neuroinflammation through multiple strategies, focusing on lifestyle changes, diet, and anti-inflammatory supplements. 

How Dietary Changes Can Reduce Neuroinflammation

Research suggests that diet plays a significant role in modulating neuroinflammation. Diets rich in anti-inflammatory components, such as the Mediterranean and DASH diets, have shown potential in reducing neuroinflammatory processes. Omega-3 fatty acids found in fish, for instance, have been found to reduce the expression of pro-inflammatory cytokines in the brain. 

Similarly, antioxidants from fruits and vegetables can suppress neuroinflammatory activity by inhibiting free radicals and the production of cytokines. On the flip side, diets high in saturated fats and processed foods can exacerbate inflammation. It's worth considering dietary changes as a part of a comprehensive strategy for managing neuroinflammation, with individualized plans potentially excluding foods that trigger sensitivities.

Anti-Inflammatory Supplements for Brain Health

Curcumin and omega-3 fatty acids appear to be beneficial for supporting brain health, particularly in the context of reducing neuroinflammation. Curcumin, a polyphenol found in turmeric, has demonstrated antioxidant and anti-inflammatory properties in studies. Similarly, omega-3 fatty acids like EPA and DHA are vital for brain functions and have been shown to positively impact neurotransmitters and cognitive well-being. 

These fatty acids are not just essential for brain function but also act as anti-inflammatory agents. A review of randomized clinical trials revealed that omega-3 supplementation enhances learning, memory, and blood flow in the brain, presenting a well-tolerated and risk-free approach to support brain health. 

Lifestyle Changes for Neuroinflammation 

Managing stress, optimizing sleep, and regular exercise are key lifestyle changes that can effectively combat neuroinflammation and support brain health. Stress has been directly linked to neuroinflammation, which in turn may contribute to a range of neurodegenerative and psychiatric conditions. Techniques like meditation can be powerful tools for reducing stress and its inflammatory effects on the brain. 

Similarly, ensuring adequate sleep duration and quality can lead to better health outcomes, including reduced inflammation. Exercise also offers a dual benefit; not only does it suppress inflammation, but it also promotes the growth of neurons and glial cells in the hippocampus, an area of the brain closely related to memory and learning. 

Detoxification Practices for Reducing Neuroinflammation

The removal of toxins from the body plays an essential role in mitigating neuroinflammation and supporting good brain health. Toxins can initiate harmful responses in the central nervous system, affecting both glial and neuronal cells and leading to either acute or chronic neuroinflammation. A key organ in this detoxification process is the liver, which breaks down harmful products, including toxins. A failure in this detoxifying function can exacerbate inflammation and result in health issues. 

Gut-Brain Connection and Neuroinflammation 

The gut-brain connection has a role in neuroinflammation and overall brain health. Research suggests that gut microbiota significantly influence bidirectional communication between the central and enteric nervous systems, often termed the gut-brain axis. Imbalances in gut microbiota have been shown to potentially contribute to neuroinflammatory conditions. 

A balanced gut microbiota is thought to aid in the maturation and activation of microglia and peripheral immune cells, which, as previously discussed, are key elements in managing inflammation in the brain. Therefore, maintaining a healthy gut microbiota through lifestyle changes for neuroinflammation, such as dietary adjustments, could offer a potential approach to managing neuroinflammation.

Future Research in Neuroinflammation

Studies in neuroinflammation are highlighting new tools for early detection and monitoring. Researchers are exploring drug and cell-based therapies, such as erythropoietin, statins, and stem cells, to both protect the brain and encourage its natural healing processes. For example, a molecule named A11 has been found to reduce inflammation and improve cognitive function.

Concurrently, there's a trend toward integrating both drug and non-drug treatments for a more comprehensive approach to managing neuroinflammation. This holistic strategy considers the close relationship between the immune system and the nervous system. It could offer benefits in treating a range of conditions linked to neuroinflammation. Scientists are also focusing on the roles that specific brain cells like microglia and astrocytes play in neuroinflammation, aiming to create treatments that are precisely tailored to these biological mechanisms.



In summary, neuroinflammation is a complex issue that requires a nuanced approach for effective treatment. The good news is that functional medicine offers a holistic perspective, targeting not just symptoms but the root causes that contribute to inflammation in the brain. 

Advances in lab testing and new research avenues for both drug-based and non-drug treatments are paving the way for more personalized and effective healthcare strategies. Staying informed about these developments and consulting with functional medicine practitioners can be beneficial steps in managing and possibly reversing the impacts of neuroinflammation on your brain health.
