📌 Study title
Case report: 60 HBOT sessions associated with pain reduction, cognitive improvement, and measurable brain changes in a woman with trauma-linked fibromyalgia
🔍 What this case report explored
Fibromyalgia is a complex chronic pain condition driven by central sensitization and neuroinflammation — processes that amplify pain signals in the brain and nervous system. In many patients, symptoms are closely linked to early-life stress or trauma.
Conventional treatments such as pain medication, antidepressants, and physical therapy often focus on symptom management, with limited impact on the underlying neurological dysfunction.
This case report followed a 62-year-old woman with:
- treatment-resistant fibromyalgia
- more than a decade of persistent symptoms
- a documented history of childhood trauma
- limited or poor response to standard medications
Researchers examined whether a structured HBOT protocol could influence pain severity, cognitive performance, physical function, and measurable brain physiology.
🌬️ HBOT protocol used in this case
The intervention consisted of:
- 60 HBOT sessions
- 12-week duration
- 90 minutes per session
- 2.0 ATA pressure
This protocol aligns with neuroplasticity-focused HBOT approaches previously explored in published brain-imaging studies by the same research group.
📊 Observed changes following HBOT
1. Reduced pain and symptom burden
Clinical assessment scores improved across major fibromyalgia measures:
- Fibromyalgia Impact Questionnaire:
60.5 → 44 - Diagnostic Criteria Score:
16 → 12
These changes reflected reductions in widespread pain, fatigue, and overall symptom severity.
2. Improved cognitive performance
Computer-based testing showed approximately 10% improvement in global cognition, including:
- memory
- processing speed
- mental clarity
Cognitive difficulties are a common and disabling aspect of fibromyalgia, making these changes particularly notable.
3. Attention increased by 27%
Attention is often one of the most affected cognitive domains in fibromyalgia. In this case, attention scores improved substantially following the HBOT protocol.
4. Reduced reliance on medication
Following the intervention:
- pregabalin (Lyrica) was discontinued
- duloxetine (Cymbalta) dosage was reduced by 50%
In long-standing fibromyalgia, medication reduction is uncommon, highlighting the significance of this observation within the context of the case.
5. Improved physical function
Functional changes included:
- walking speed increased from 3.2 to 4.5 km/h
- improved balance and coordination
- reduced movement-related discomfort
6. Objective brain changes supported the clinical findings
Neuroimaging revealed measurable brain-level changes consistent with neuroplastic adaptation:
- increased cerebral perfusion on SPECT imaging
- improved white-matter integrity on diffusion tensor MRI
These objective findings aligned with the reported changes in pain, cognition, and physical performance.
🧠 Why this case matters
This report illustrates several points of interest within HBOT research:
- HBOT was explored as a neuroplasticity-oriented intervention, not only a pain-focused approach
- Improvements were observed despite long-standing symptoms and central sensitization, a population often considered difficult to impact
- Reduced medication use coincided with functional and cognitive changes
- Objective brain imaging provided biological context for the clinical observations
The findings are consistent with earlier research examining how hyperbaric oxygen exposure may influence neuroinflammation and trauma-related brain network dysfunction.
📌 Takeaway for the community
In this individual case, a structured HBOT protocol was associated with:
- reduced pain and symptom severity
- improved cognition and attention
- enhanced walking speed and physical coordination
- decreased reliance on certain medications
- measurable changes in brain perfusion and white-matter integrity
While this is a single case report and not a controlled trial, it adds to the growing research discussion around HBOT, neuroplasticity, chronic pain, and trauma-related conditions.
🫧 HBOT Radar continues to track and summarize emerging studies on chronic pain, trauma-linked conditions, and neuroplasticity-focused HBOT research.
