Outcome

This study provides compelling evidence that hyperbaric oxygen therapy (HBOT) significantly reduces fatigue and enhances cognitive functions in long COVID patients. Administered over 10 sessions at 2.4 atmospheres for 1 hour and 45 minutes each the treatment resulted in marked improvements in fatigue levels as well as in global cognition executive function attention information processing speed and verbal function all without adverse events.

Introduction

Long COVID often leaves sufferers with persistent and debilitating fatigue even months after recovering from the initial COVID-19 infection. Limited treatment options have made it essential to seek new interventions. Hyperbaric Oxygen Therapy (HBOT) has emerged as a potential treatment for managing these lingering symptoms. This study aimed to evaluate the efficacy of HBOT in alleviating fatigue and improving cognitive functions in long COVID patients. Ten participants underwent 10 sessions of HBOT over 12 days each session lasting 1 hour and 45 minutes at a pressure of 2.4 atmospheres. The findings revealed statistically significant improvements in fatigue global cognition executive function attention information processing speed and verbal function with no adverse events reported. These results suggest that HBOT could be a promising intervention for individuals grappling with long COVID offering a much-needed beacon of hope for those experiencing persistent and challenging symptoms.

Results

The study demonstrates significant improvements in long COVID-related symptoms following hyperbaric oxygen therapy (HBOT). Conducted over 12 days 10 patients underwent 10 HBOT sessions each lasting 105 minutes at a pressure of 2.4 atmospheres.

The primary outcome was a substantial reduction in fatigue levels as measured by the Chalder fatigue scale with results showing a statistically significant decrease (p=0.0059; d=1.75) indicating a very large effect size.

In addition to addressing fatigue the study observed extensive enhancements in various cognitive functions:

1. Global Cognition: Significant improvement (p=0.0137; d=–1.07 large effect).
2. Executive Function: Marked enhancement (p=0.0039; d=–1.06 large effect).
3. Attention: Notable gains (p=0.0020; d=–1.2 very large effect).
4. Information Processing Speed: Significant increase (p=0.0059; d=–1.25 very large effect).
5. Verbal Function: Considerable improvement (p=0.0098; d=–0.92 large effect).

Importantly the intervention reported no adverse events underscoring the safety profile of HBOT in this patient cohort. These findings indicate that HBOT holds substantial promise as a therapeutic strategy for mitigating the fatigue and cognitive deficits associated with long COVID offering a valuable intervention for those suffering from these persistent symptoms.

Conclusion

In conclusion the study provides compelling evidence that Hyperbaric Oxygen Therapy (HBOT) effectively mitigates fatigue and enhances cognitive functions in long COVID patients. Over just 10 sessions participants exhibited marked improvements in fatigue global cognition executive function attention information processing speed and verbal function suggesting HBOT’s potential as a robust therapeutic option. These findings are particularly significant in the context of long COVID where persistent fatigue severely impacts quality of life and daily functioning. The absence of adverse events further underscores the safety and viability of HBOT for this patient population. Future research should focus on larger and more diverse cohorts to validate these promising results and explore the long-term benefits and mechanisms of HBOT. This study paves the way for HBOT to become a valuable tool in the management of long COVID symptoms offering renewed hope to those afflicted by the lingering effects of the disease.
