FND, Trauma, Stress and Allostatic Loads

FND followed “difficult times” in 78% of cases.

Therapists at EasingFND believe there is an association between the onset of FND and high allostatic loads. That is, times of biological, psychological or social stressors. This can range from traumatic or stressful incidents, to surgery, infections, injections, injury, challenges, etc.

In August 2026, we conducted an informal study via a FND Facebook Group.

We asked the group “Just wondering how many FND sufferers were having a particularly difficult time (trauma; stress; illness; surgery) a few months before symptoms started?”

We received 118 responses.

Of those, 76% said yes (76 respondents) including after illness, injections and injuries.

22% said no (23 respondents).

1 person said they weren’t sure.

There certainly appears to be a link here, and we believe it is something worth researching further.

It could be that the body is stuck in “shock” – the “fight and flight” state.

If this is the case, treatments such as Havening, that can help to release the encoding trauma, could have the potential to ease the symptoms.
