Editor’s Note
Dear FNDS Members,
Last June we had the opportunity to finally meet in person during the FNDS Conference in Boston, MA. It was a great experience with multiple high yield topics from experts around the world. The Conference was a success with 306 in person and 852 online attendees. We are glad to highlight some of the talks in this newsletter and remind you that registered members have online access to the lectures.
In this number of the newsletter, you would like to review the important work by D. Perez, MD, MSC and his group in the science of emotions and its implications to FND. Below you will find a link to the original article and commentary by Erica Sieg, PsyD.
We wanted to share a recent interview with the Centre Hospitalier de l’Université de Montreal (CHUM). At the CHUM a multidisciplinary team of neurologists, neuropsychiatrist, occupational and physical therapists are making a difference for FND patients in Canada.
Finally, I would like to take this opportunity to thank all our members and your support for the success of the society. It is through your voice that we can expand our reach and involve new trainees to take on the future of FNDS. For that reason, all trainees have a free membership during the first year and discounted membership thereafter during their training.
Best,
Editorial Team

Highlights of the FNDS Conference
|

One of the most important moments at the FNDS Conference was when a patient advocate took the stage to describe his experience as a patient and how we can move forward in improving the relationship between physicians and institutions with patients. Here are the comments by FND Portal.
“FND has ripple effects. It touches the people who have it, our families, and the societies into which we’re born. So, it felt fitting that FNDS 2022 put FND, and the people who have it, at the center of a badly needed interdisciplinary dialogue. Researchers, clinicians, and people with FND came together to confront the hard challenges: how can we better understand the brain dynamics of this disorder? How can we find treatments that work? How can we begin to address the uncountable forms of harm that medical systems have inflicted on this marginalized group of patients? Yes, these are hard challenges. But FNDS 2022 proves there are people who will take them on. I hope the ripples travel far.”

My favorite presentation was by Dr. Lisa Feldman Barrett with a brilliant summary of her research on interoception and emotions. Some of it is summarized in the paper highlighted in this issue of the Newsletter. Lisa describes 3 main lessons she has learned over the year. First, the mind and body are not two separate components fighting for dominance. Your body is at the core of your mind and the main function of the brain is to regulate a complicated body system. Second, the brain does not react to sense but predicts and anticipates the next actions. In that way, your brain constructs your experiences as it predictively controls your body. The third and final lesson is that physical signals become meaningful only concerning other signals. Emotions that seem to happen to you are made by you and Emotions you seem to detect in other people are partly inside your head.
If you registered for the FBDS Conference either in person or virtual, you still have the option to review the lectures. Although we would love to summarize all it would be impractical for this publication. For that, the FNDS Newsletter team suggests you take special attention to some of our favorites including Functional Syncope-Like Events by J. Ger van Dijk, Functional Cauda Equina Syndromes by Ingrid Hoeritzauer, and the Video Grand rounds which includes 5 great case presentations.

Summary of the "A New Science of Emotion: Implications for Functional Neurologic Disorder" published in Brain by J. Jungilligens et al.
This article covers important aspects of the role of emotions in FND by first describing and considering the basis of emotions in general. It particularly highlights Dr. Feldman-Barretts theorized work that emotions are part of a predictive process, categorizing sensory input with available learned concepts (for the sake of brain efficiency). It then posits that FND may arise from alterations in emotional category constructions. The neuroanatomy informing prediction and prediction error detection highlight the relevant roles of default mode, salience, and sensory-motor networks. They propose studying emotional granularity to understand the potential role of emotional category constructs in FND symptoms.
