Symptoms in government workers

 April 6, 2023

In 2015 US embassy employees and family members living overseas began reporting symptoms that had a sudden onset and included dizziness, pain, visual problems and cognitive dysfunction.

These symptoms are often thought to have been causedby wireless radiation1 and were originally called ‘Havana Syndrome’ because they were reported in Cuba. However, similar symptoms have now been reported in other geographic locations as well and the US Government has chosen to refer to them as ‘anomalous health incidents’ (AHIs).

In two papers published last month, researchers investigated the condition in more detail.

The first study compared government employees with and without AHI.2

While the researchers didn’t find differences between the groups for all of the tests they conducted, they did find some interesting results. They found:

  • ‘Headache was the most common symptom (74%) following AHI, followed by cognitive challenges (69%), sleep disorders (59%), tinnitus (56%), imbalance (52%), dizziness (37%), and vision change concerns (37%). The most common type of headache was migraine headache (36%), followed by new daily persistent headache (29%), and unspecified headache (19%; mostly transient headache following AHI).’

  • ‘Individuals with AHIs reported significantly more posttraumatic stress …, fatigue …, and depressive symptoms, as well as reduced satisfaction with life …compared with control participants’.

  • Participants with AHIs scored worse on self-reported balance questionnaires.


These symptoms are consistent with those reported by people exposed to wireless radiation.

The second study involved MRI brain imaging of small numbers of people with and without AHI.

The authors reported, ‘we did not find substantial differences between AHI and control groups, except for the functional connectivity in the salience networks.’ They added, ‘That this study did not identify a neuroimaging signature of brain injury in this AHI cohort does not detract from the seriousness of the clinical condition.’
