FND: What can research tell us about the brainโbody connection? ๐ง ๐ซ
A new 2026 pilot study explored the relationship between cardiac autonomic activity and brain connectivity in people with Functional Neurological Disorder (FND).
There was no simple difference in heart rate or heart-rate variability between the FND group and comparison group. However, within the FND group, differences in these measures were associated with connectivity in brain regions involved in interoception, autonomic regulation, salience and movement.
For me, this raises an important OT question:
How do bodily signals, movement, environment and everyday activity interact for the individual?
FND is complex. It isnโt simply โstressโ or anxiety, and this small pilot study cannot tell us whether these relationships cause symptoms, result from them, or represent adaptation.

My clinical perspective:
As an Occupational Therapist, I have experience working within multidisciplinary teams alongside physiotherapy and CAMHS/paediatric services, supporting young people where FND symptoms affected physical function and everyday participation. My experience has included functional rehabilitation alongside psychological approaches, including CBT-informed and DBT-based strategies such as mindfulness and self-soothing.
This is where OT can help โ looking beyond the symptom to understand what is affecting everyday life and participation.
