A Parkinson’s disease diagnosis can change nearly every part of daily life. Tremor and stiffness may be the most visible symptoms, but many patients also experience poor sleep, fatigue, mood changes, and difficulty thinking clearly.

Medication, exercise, physical therapy, occupational therapy, and speech therapy remain central to Parkinson’s care. At the same time, researchers are investigating whether hyperbaric oxygen therapy, or HBOT, could become a useful supportive therapy for selected patients.

The early findings are encouraging enough to study further, but they do not show that HBOT cures Parkinson’s disease or replaces established medical treatment.

What Is Hyperbaric Oxygen Therapy?

During HBOT, a patient breathes oxygen inside a chamber where the atmospheric pressure is increased. Under pressure, the lungs can take in considerably more oxygen than they can under normal conditions.

This temporarily increases the amount of oxygen carried in the blood plasma. Oxygen can then reach tissues affected by reduced circulation, inflammation, or metabolic stress.

Researchers have proposed several reasons HBOT might be relevant to neurologic conditions. These include its possible effects on:

• Tissue oxygen availability
• Inflammatory signaling
• Oxidative stress regulation
• Mitochondrial activity
• Blood-vessel growth and circulation
• The brain’s ability to adapt after injury

These mechanisms are biologically interesting, but a plausible mechanism is not the same as proven clinical benefit.

What Did the Recent Parkinson’s Research Find?

A systematic review and meta-analysis published in 2025 combined 13 studies involving 958 participants with Parkinson’s disease. The researchers reported improvements in measures of motor function, cognition, sleep quality, and daytime sleepiness among patients receiving HBOT alongside conventional care.

The reported motor improvement included a modest change in the motor section of the Unified Parkinson’s Disease Rating Scale. The analysis also found favorable results on commonly used cognitive and sleep questionnaires. Read the Parkinson’s meta-analysis on PubMed.

These results are promising, particularly because sleep and cognitive symptoms can have a substantial effect on quality of life. However, they require careful interpretation.

The studies used different treatment protocols and were not all conducted under the same research conditions. A pooled analysis can identify a signal worth investigating, but it cannot establish that HBOT slows the underlying disease or produces the same response in every patient.

An earlier scientific review noted that much of the foundational Parkinson’s research involved laboratory and animal models. It called for stronger human studies to determine whether proposed neuroprotective effects translate into meaningful clinical outcomes. Review the earlier evidence on PubMed.

Is HBOT an Established Treatment for Parkinson’s Disease?

No. HBOT for Parkinson’s disease remains an off-label, investigational application.

That distinction matters. It means research is underway, but the evidence is not strong enough to treat HBOT as a standard Parkinson’s therapy. It should never be presented as a substitute for medication, neurologic care, rehabilitation, exercise, or other recommended treatment.

For an appropriate patient, a physician might consider HBOT as one part of a broader supportive plan. The goals should be clearly defined and measurable, for example, monitoring walking, sleep, fatigue, or cognitive function rather than relying on vague claims about “healing the brain.”

What Should Patients Consider?

HBOT requires medical screening because pressure changes and concentrated oxygen are not appropriate for everyone. A qualified clinician should review:

• Current medications and supplements
• Lung conditions or a history of collapsed lung
• Ear or sinus pressure problems
• Seizure history
• Recent surgery or implanted medical devices
• Blood-sugar management
• Claustrophobia or anxiety inside enclosed spaces

Common side effects can include temporary ear pressure, sinus discomfort, fatigue, and temporary vision changes. More serious complications are uncommon but possible, which is why medical supervision and appropriate equipment are essential. Review published HBOT side-effect information on PubMed.

A Balanced View of the Evidence

The newest Parkinson’s research gives patients and physicians a legitimate reason to remain interested in HBOT. The findings suggest possible benefits involving motor symptoms, cognition, and sleep, but the evidence does not yet prove disease modification.

Future studies should use standardized protocols, credible comparison groups, longer follow-up periods, and clearly defined patient populations. Until then, HBOT should be discussed honestly: promising, medically interesting, and still investigational for Parkinson’s disease.

For many people, Lyme disease does not end when antibiotic treatment is completed. Fatigue, muscle and joint pain, headaches, disrupted sleep, and difficulty concentrating may continue to affect work, relationships, exercise, and everyday life.

These symptoms are real, even when routine testing does not provide a simple explanation.

Researchers often use the term post-treatment Lyme disease syndrome, or PTLDS, when certain symptoms continue for at least six months after a person has completed recommended antibiotic treatment. Scientists are still studying why this happens and why some people recover quickly while others experience persistent symptoms.

For patients searching for additional ways to support recovery, hyperbaric oxygen therapy—or HBOT—may come up in conversation. Although HBOT is not an FDA-cleared treatment for Lyme disease or PTLDS, early research and limited clinical reports have created interest in its potential role as an adjunctive therapy.

Understanding Persistent Symptoms After Lyme Disease

Lyme disease is caused by bacteria from the Borrelia group and is most commonly transmitted through the bite of an infected tick. When diagnosed early, Lyme disease is generally treated with antibiotics.

Most patients improve after treatment. However, a subset of patients continues to experience symptoms such as:

• Persistent fatigue
• Muscle or joint discomfort
• Problems with memory or concentration
• Headaches
• Changes in sleep
• Reduced exercise tolerance
• Numbness, tingling, or other neurologic symptoms
• Difficulty returning to normal daily activities

A review published in Frontiers in Medicine described fatigue, cognitive difficulties, and musculoskeletal pain as common features reported by patients with PTLDS. The authors also emphasized that the biological processes contributing to these symptoms are not yet fully understood. Read the published review.

Potential explanations being investigated include changes in immune activity, persistent inflammation, tissue injury, altered neurologic function, and other effects that may remain after the initial infection has been treated. Different patients may have different factors contributing to their symptoms, which is one reason a thorough medical evaluation remains important.

What Is Hyperbaric Oxygen Therapy?

Hyperbaric oxygen therapy involves breathing increased concentrations of oxygen while inside a chamber pressurized above normal atmospheric pressure.

Under pressure, more oxygen can dissolve into the plasma and other body fluids. This allows oxygen to reach tissues through pathways that do not depend entirely on red blood cells. The combination of oxygen and pressure can also influence several biological processes involved in recovery.

Research suggests that HBOT may affect:

• Tissue oxygenation
• Inflammatory signaling
• Blood-vessel development
• Cellular energy production
• Immune activity
• The body’s repair responses

These effects are not specific to Lyme disease. They are part of the broader physiology researchers study when evaluating HBOT for wounds, neurologic injuries, inflammatory conditions, and other medical concerns. A widely cited scientific review by Stephen Thom, MD, PhD, discusses the mechanisms through which hyperbaric oxygen may influence inflammation and tissue repair. Review the published article.

What Does the Lyme Disease Research Show?

At this time, the evidence for using HBOT in patients with Lyme disease is limited.

A 2014 publication described a patient with persistent Lyme-related symptoms who experienced improvement after completing a course of HBOT. The authors called HBOT an adjunctive treatment, meaning it was used in addition to other medical care rather than as a replacement. They also acknowledged that published information about its effectiveness remained limited. Read the case report.

A case report can help identify an area worth studying, but it cannot establish that a treatment will work for most patients. It does not include a control group, and improvement in one person may not predict what another patient will experience.

An earlier review of Lyme borreliosis treatment options also noted interest in HBOT while emphasizing that controlled clinical trials had not yet been completed. Read the treatment review.

This distinction matters. There is a medical basis for continued research, but there is not currently enough evidence to say that HBOT cures Lyme disease, eliminates persistent infection, or produces predictable results for every patient.

What Might HBOT Be Used to Support?

When HBOT is considered for someone with a history of Lyme disease, the goal should be clearly defined.

Rather than promising to “kill Lyme,” a responsible treatment discussion may focus on whether HBOT could support concerns such as:

• Persistent fatigue
• Cognitive complaints or “brain fog”
• Chronic pain
• Reduced physical function
• Slow recovery after illness
• Inflammatory or neurologic symptoms

Even then, outcomes cannot be guaranteed. Symptoms associated with PTLDS can overlap with thyroid disorders, anemia, autoimmune conditions, sleep disorders, medication effects, nutritional deficiencies, other infections, and neurologic or cardiovascular problems.

HBOT should not replace an appropriate evaluation for these possibilities.

HBOT Is an Adjunct: Not a Replacement for Lyme Treatment

Hyperbaric oxygen therapy is not a substitute for antibiotics when antibiotics are medically indicated. It should also never be used as a reason to delay evaluation of new or worsening symptoms.

Patients considering HBOT should involve the healthcare professionals managing their Lyme disease or persistent symptoms. Coordination becomes especially important when a patient has heart, lung, ear, neurologic, blood-sugar, or medication-related concerns.

At RX-O2, a consultation is used to review a patient’s history, current symptoms, prior treatment, medications, possible contraindications, and goals. This helps determine whether HBOT may be reasonable as part of a broader care plan.

Safety Matters

HBOT is a medical treatment involving increased pressure and oxygen exposure. Temporary ear or sinus pressure is among the more common side effects. Other potential risks include temporary vision changes, blood-sugar changes, confinement anxiety, pulmonary effects, and, rarely, oxygen-related seizures.

A published review of HBOT side effects emphasizes the importance of proper screening, trained personnel, appropriate treatment protocols, and informed consent. Review the HBOT safety article.

Patients should look for a facility that provides:

• Medical screening before treatment
• FDA-cleared hard-shell hyperbaric chambers
• Trained and certified hyperbaric personnel
• Continuous patient supervision
• Written safety and emergency procedures
• Individualized pressure and oxygen protocols
• Communication with the patient throughout treatment

More pressure and more oxygen do not automatically mean better results. The safest and most appropriate protocol depends on the individual patient.

A Thoughtful Path Forward

Living with persistent symptoms after Lyme disease can be frustrating, particularly when the symptoms are difficult to measure or explain. Patients deserve to be taken seriously while also receiving honest information about what is known—and what remains uncertain.

HBOT has biological effects that may be relevant to inflammation, tissue oxygenation, and recovery. However, Lyme-specific research currently consists largely of limited clinical observations and case-level evidence. Larger, controlled studies are still needed.

For the right patient, HBOT may be considered as one part of a coordinated recovery plan. The decision should begin with careful screening, realistic goals, and a discussion of the potential benefits, limitations, and risks.

Could HBOT Be Appropriate for You?

If you are living with persistent symptoms following Lyme disease treatment, RX-O2 can review your medical history, current concerns, and recovery goals. A consultation does not guarantee that HBOT will be recommended, but it can help you make a more informed decision.

Unlocking the Potential of Hyperbaric Oxygen Therapy for Brain Health and Recovery

In recent years, the spotlight on brain health has intensified, driven by growing awareness of the impact of traumatic brain injuries (TBI) and the potential for new therapeutic approaches. One such promising avenue is Hyperbaric Oxygen Therapy (HBOT), which has gained attention for its potential benefits in brain health and recovery, particularly in the realm of sports and TBI. In this blog, we’ll explore how HBOT works, its potential benefits for brain health, and its applications in treating sports-related injuries.

What is Hyperbaric Oxygen Therapy?

Hyperbaric Oxygen Therapy involves breathing pure oxygen in a pressurized room or chamber. Unlike normal air, which contains about 21% oxygen, the air inside a hyperbaric chamber is enriched with 100% oxygen and is delivered at pressures higher than sea level (usually between 1.5 to 3 times atmospheric pressure). This increased pressure allows oxygen to dissolve directly into the blood plasma, enhancing its delivery to tissues throughout the body.

How HBOT Works

The basic premise of HBOT is simple: increased oxygen levels accelerate healing and reduce inflammation. Under hyperbaric conditions, oxygen reaches even the most damaged cells, stimulating the body's natural repair processes. For the brain, this can mean improved cellular function, reduced swelling, and enhanced tissue regeneration.

Brain Health and Hyperbaric Oxygen Therapy

Traumatic Brain Injury (TBI)

TBI is a significant concern in both civilian and sports contexts. It can result from impacts or blows to the head, causing a range of symptoms from mild concussions to severe brain damage. Traditional treatments for TBI focus on managing symptoms and preventing further injury, but they often fall short in promoting comprehensive recovery.

Recent studies suggest that HBOT can offer additional benefits for TBI patients. The therapy helps to:

• Reduce Inflammation: HBOT has been shown to decrease neuroinflammation, a common issue in brain injuries. By reducing inflammation, the therapy can potentially mitigate some of the secondary damage following an injury.
• Promote Neurogenesis: The increased oxygen supply can stimulate the growth of new neurons and support the repair of damaged brain cells, which is crucial for long-term recovery.
• Improve Cognitive Function: Research indicates that HBOT may enhance cognitive function and memory by improving overall brain health and function.

Sports-Related Injuries

Sports, especially contact sports like football, hockey, and boxing, carry a higher risk of brain injuries. Concussions, repeated head impacts, and other forms of TBI are not uncommon, and their long-term effects can be debilitating.

For athletes, HBOT offers several benefits:

• Enhanced Recovery Time: Athletes often seek faster recovery to return to their sport. HBOT can potentially shorten the recovery period by accelerating healing processes.
• Reduction in Chronic Symptoms: For those suffering from post-concussion syndrome or chronic traumatic encephalopathy (CTE), HBOT may offer symptom relief by addressing the underlying inflammation and promoting brain repair.
• Preventive Measures: While still under investigation, some experts believe that regular use of HBOT might help to mitigate damage from repeated head impacts, although this use is controversial and not yet widely endorsed.

The Science Behind It

While anecdotal evidence and preliminary studies show promising results, the scientific community continues to investigate the full extent of HBOT’s benefits for brain health. Clinical trials are ongoing to better understand its efficacy and optimize treatment protocols.

For example, a study published in the Journal of Neurotrauma found that HBOT significantly improved cognitive and emotional functioning in patients with chronic TBI. Another study in Frontiers in Neurology highlighted its potential to reduce post-concussion symptoms and aid recovery.

Considerations and Future Directions

While HBOT holds promise, it’s important for patients and athletes to approach it with informed caution. Not all conditions may benefit from HBOT, and potential risks or side effects need to be considered. Consulting with a medical professional who specializes in HBOT is crucial to determine if it’s a suitable option.

Future research will likely refine treatment protocols and uncover more about how HBOT can be optimized for brain health. As understanding deepens, it’s expected that hyperbaric therapy will become a more integrated part of brain injury management and sports medicine.

Conclusion

Hyperbaric Oxygen Therapy presents an exciting frontier in the realm of brain health and recovery. With its potential to reduce inflammation, promote healing, and enhance cognitive function, it offers a hopeful adjunct to traditional treatments for TBI and sports-related brain injuries.

As research continues to evolve, HBOT could play a pivotal role in advancing brain health and recovery strategies, offering athletes and TBI patients a promising path to improved outcomes and quality of life.

If you or someone you know is considering HBOT, consult with healthcare professionals to explore if it’s the right option for you. As we continue to unlock the potential of this therapy, the future of brain health looks increasingly promising.
