Unraveling the Havana Syndrome Mystery: New Brain Scan Analysis Reveals Surprising Findings

Two new studies on the mysterious 'Havana syndrome' found no physical cause but suggested a possible link to mental health, with researchers finding no significant differences in brain scans or other biological tests between people with Havana syndrome and healthy controls. While the results provide little insight into a possible biological explanation for the symptoms, they did find that people with Havana syndrome self-reported more problems with balance and higher levels of fatigue, depression, and post-traumatic stress disorder compared to the control group. The researchers suggest that if the Havana syndrome symptoms were caused by an external factor, it's possible they are no longer detectable with current tests and sample sizes.
