In earlier newsletters I discussed the four key components of pain, including brain pain (brain inflammation).

Brain pain is so important that I think it's a good idea to do a deeper dive—because it can be powerful In helping you get pain free, using simple tools such as PEA, LDN, Melatonin and Metformin.

Brain inflammation is very common in CFS, fibromyalgia, Long Covid, chronic Lyme, EBV, and many other conditions. It amplifies your pain, fatigue, weight gain, brain fog and sensitivities. A free 5-minute quiz called the "Central Sensitization Inventory CSI" (see below) can screen you for brain inflammation.

Why Brain Inflammation Matters

Free 5 minute screening for brain inflammation (Microglial activation)

A free 5 minute online quiz called "Central Sensitization Inventory (CSI)" can screen for brain inflammation (called microglial activation) in those with chronic pain. Simply hit the “Begin” button on each of the first 2 pages you (can ignore the rest of what's on those 2 pages) and do the questionnaire. It will give the final score at the end. Easy as can be! To interpret it:

  • Mild: 30 to 39
  • Moderate: 40 to 49
  • Severe: 50 to 59
  • Extreme: 60 to 100

This is the same validated tool used by researchers. Much easier than a brain biopsy;-)

If high, Central Sensitization, which is caused by the brain inflammation (microglial activation) is present. This also contributes to the weight gain seen in CFS/fibromyalgia, as well as amplifying pain, fatigue, brain fog and sensitivities. Our next study, which we are currently designing, will be to reset this and other components causing weight gain—so people can finally lose the average 32 pounds of weight they gain from CFS/fibromyalgia. Stay tuned!

In recent years scientists have discovered that many chronic health conditions share a common driver: inflammation in the brain. This is especially important in conditions that send people to holistic practitioners, including chronic Lyme Disease (and other infections), fibromyalgia, CFS, Mast Cell Activation Syndrome (MCAS), and chronic pain.

Brain inflammation is driven by specialized immune cells called "microglia." Microglia act as the brain’s gardeners. They patrol the nervous system, clear debris, fight infections, and help repair injured tissue.

Under healthy conditions, these microglial "gardeners" are mild mannered. They quietly feed and tend to brain cells. But sometimes they become overactivated. This can happen after:

  • Viral and other infections, such as Chronic Lyme, Long COVID and EBV reactivation
  • Physical injury, such as Traumatic Brain Injury (TBI)
  • Severe chronic stress
  • Chronic autoimmune inflammation in the body, such as MS and Lupus
  • Toxin exposures and MCAS

Once activated, microglia release many inflammatory chemicals that can affect nerve signaling, energy production, and brain communication. The most helpful treatments often work by calming several of these pathways at once. Researchers now believe that excessive microglial activation may contribute to symptoms seen in conditions such as:

  • chronic fatigue syndromes
  • long-lasting post-viral illness
  • fibromyalgia
  • chronic pain disorders
  • brain fog
  • depression

Interestingly, one of the mechanisms of Prednisone for pain relief is suppressing microglial activation. These natural options may help one to come off the Prednisone while still being comfortable. Fortunately, a rapidly growing body of research suggests that microglial activation can often be calmed or “reset.”

How to Calm Microglial Activation/Brain Inflammation

In calming brain inflammation, the following approaches have the best combination of effectiveness, safety, accessibility, and affordability. I've listed them roughly in order of clinical usefulness.

  1. Palmitoylethanolamide (PEA)
  2. Omega-3 fatty acids (fish oil)
  3. Low-Dose Naltrexone
  4. Curcumin
  5. Melatonin
  6. Regular moderate exercise
  7. Good sleep

Let's look at each.

1. Palmitoylethanolamide (PEA)

PEA is a naturally occurring fatty molecule produced by the body to regulate inflammation. It helps stabilize immune cells in the brain and reduces inflammatory signaling. Many clinicians consider it one of the most promising compounds for calming neuroinflammation. The main problem is poor absorption. So I use PEA Healthy Inflammation Response, which contains natural gamma cyclodextrin to dramatically enhance absorption.

Typical dosing: 600–1,200 mg daily. For severe conditions, such as chronic pain, higher dosing (see this study) of 1,200 mg daily for 1 month followed by 1,200 mg twice a day for two months gives a fair therapeutic trial and may accelerate recovery

Time to benefit: 4–12 weeks.

Why it stands out: It has an excellent safety profile, targets multiple inflammatory pathways, and is widely available as a supplement.

2. Omega-3 Fatty Acids (Fish Oil)

Omega-3 fats help the body produce PGE3, which actively decreases inflammation. These compounds help shift immune cells from an inflammatory state into a repair mode.

Typical dosing: 2,000–4,000 mg combined EPA + DHA daily.

A simper alternative? I use one with vectorized phospholipid forms of omega 3s. This is available as Vectomega® and allows 1-2 capsules a day to replace 7-14 large fish oil caps. I use Vectomega myself.

Time to benefit: 4–8 weeks

3. Low-Dose Naltrexone

At very low doses, Low-Dose Naltrexone (LDN) works differently than when used in addiction treatment. It helps regulate immune signaling and can reduce overactivation of microglia. Many holistic clinicians use it for chronic pain, autoimmune illness, and post-viral conditions.

Typical dosing: 1.5–4.5 mg at bedtime.

Time to benefit: 8 weeks.

Advantages: It's an inexpensive generic medication, and it's generally safe and well tolerated (though some people may need to start with very tiny doses and move up slowly).

Good general articles are available for the public on this, including use of LDN and how to titrate dosing.

4. Curcumin

Curcumin is a compound found in turmeric. It helps turn down inflammatory signaling inside cells. It also supports antioxidant defenses in the brain.

Typical dosing: 500–1,500 mg daily of an enhanced-absorption formulation, such as CuraMed®.

Time to benefit: 4–8 weeks.

Additional benefits: It provides marked pain relief while decreasing overall inflammation.

5. Melatonin

Melatonin is best known as a sleep hormone, but it also strongly regulates immune signaling in the brain. It can reduce activation of inflammatory pathways and protect mitochondria.

Typical dosing: 3–10 mg at bedtime.

Time to benefit: 2–4 weeks.

Additional benefits: It improves sleep, which itself reduces brain inflammation and pain. I use a 10 mg sustained release called Melatonin EP120™.

6. Regular Moderate Exercise

Exercise is one of the most powerful natural regulators of inflammation. During activity, muscles release molecules that signal the brain to reduce inflammatory activity.

Recommended approach: Set aside 20-40 minutes most days of the week for moderate intensity exercise.

Time to benefit: 3–6 weeks.

7. Good Sleep

Deep sleep is when the brain clears inflammatory by-products and resets immune signaling. Improving sleep quality alone can significantly reduce neuroinflammation.

Key strategies:

  • Keep a consistent sleep schedule.
  • Sleep in darkness at night (an eye mask can help sleep quality).
  • Reduce evening screen exposure, or switch from blue to “warmer” night light settings such as those found on Kindle and cell phones.

Putting It All Together

A practical starting strategy often includes:

  1. Palmitoylethanolamide (PEA)
  2. Omega-3 fatty acids (fish oil)
  3. Low-Dose Naltrexone
  4. Curcumin
  5. Melatonin
  6. Lifestyle factors such as regular moderate exercise, and
  7. Good sleep

The benefits for relieving any kind of chronic pain can be dramatic! Give it 2-3 months to work, though it can be much quicker.
