Outcome

The study demonstrated that Hyperbaric Oxygen Therapy (HBOT) could effectively reduce anxiety and improve social behaviors in a mouse model of Fragile X Syndrome (FXS). HBOT-treated mice exhibited increased thigmotaxis enhanced motor activity with fewer anxiety-related behaviors and higher levels of social interaction across different behavioral tests including the open field test the elevated plus maze test and the three-chambered social approach test.

Introduction

Fragile X Syndrome (FXS) is a common genetic condition that causes intellectual disability and is often accompanied by significant anxiety and abnormal social behaviors. While current treatments primarily focus on managing symptoms novel therapeutic approaches are being explored to improve the quality of life for individuals with FXS. This study investigates the potential of Hyperbaric Oxygen Therapy (HBOT) as a treatment for anxiety and social deficits in a mouse model of FXS. The research examines behavioral changes in Fmr1 knockout mice which serve as a model for FXS following HBOT treatment. The findings suggest that HBOT-treated mice exhibit increased motor activity reduced anxiety-related behaviors and enhanced social interaction pointing to HBOT’s potential as a novel treatment avenue for managing FXS-associated symptoms.

Results

The study explored the impact of Hyperbaric Oxygen Therapy (HBOT) on anxiety and social behaviors in a Fragile X Syndrome (FXS) mouse model. FXS is characterized by mental retardation and anxiety-related social behavior abnormalities. Significant alterations in behaviors were observed in HBOT-treated mice compared to the control group.

In the open field test HBOT-treated mice displayed increased thigmotaxis characterized by a preference for the periphery of the open area. This behavior indicates an altered response to the environment and potentially lower anxiety levels as the mice opted to stay close to the walls instead of exploring the central regions.

In the elevated plus maze test HBOT-treated mice exhibited reduced anxiety-related behaviors. These mice spent more time and traveled longer distances in the open arms of the maze indicating enhanced motor activity and decreased anxiety. Conversely they spent less time in the closed arms which typically denotes higher anxiety levels.

The three-chambered social approach test further elucidated changes in social behavior. HBOT-treated mice demonstrated increased social interactions and reduced social anxiety. During the sociability test these mice made more frequent approaches to a wire cup containing another mouse compared to the control group. Additionally in the social novelty preference test HBOT-treated mice often approached a wire cup containing a stranger mouse showcasing their willingness to engage with unfamiliar conspecifics. These behaviors cumulatively suggest enhanced social behavior and reduced social anxiety following HBOT.

Collectively the findings underscore HBOT’s potential to positively modify both anxiety and social behaviors in Fmr1 knockout mice. The study indicates a marked improvement in social interactions and a reduction in anxiety-related behaviors following HBOT.

Conclusion

In conclusion this study indicates that Hyperbaric Oxygen Therapy (HBOT) has the potential to mitigate anxiety and enhance social behaviors in a mouse model of Fragile X Syndrome (FXS). Key findings showed that HBOT-treated mice displayed increased thigmotaxis reduced anxiety-related behaviors and improved social interactions in various behavioral tests including the open field test the elevated plus maze test and the three-chambered social approach test. These results underscore the therapeutic promise of HBOT in addressing the anxiety and social deficits associated with FXS. Future research should focus on optimizing HBOT parameters and exploring its long-term effects to better understand its clinical applications for FXS and potentially similar conditions.
