The spirit of the workshop

Non-invasive brain stimulation (NIBS) techniques have demonstrated their efficacy in treating psychiatric disorders. They also showed some limitations, such as those intrinsic to the one-size-fits-all targeting and stimulation methods. If we want NIBS to go beyond their own limits, we will have to take into consideration the heterogeneity of neuropsychiatric disorders in terms of targets and response to different stimulation protocols and technics, i.e., to enter into the era of precision / personalized medicine. This question will be addressed along different axes.

1 - It seems necessary to go beyond the atheoretical and consensual diagnostic categories, derived from traditional classifications, and identify the pathophysiological mechanisms involved in the different subtypes of psychiatric disorders. Deep phenotyping and machine learning are potential tools for this paradigm shift.

2 - This comes with the development of new brain imaging acquisitions and analyses tools that could help the identification individualized specific targets for neuromodulation. Progress in individual functional imaging will be discussed (e.g., BOLD-connectivity, ASL-perfusion MRI, analysis of the brain dynamics).

3 - Personalized stimulation necessarily implies that the identified targets may actually be reached and modulated in the right way. Innovations in precision (e.g., neuronavigated robotized positioning, deep-stimulation techniques like focused ultrasound) and the on-line monitoring of the therapeutic effect (e.g., pre/post-EEG, online NIRS) are likely to change our future practice.

By bringing together experts in this rapidly evolving field, our ambition is to promote fruitful discussions and identify complementarities. We believe that if each contribution would already be an indisputable progress, the most decisive advances for our patients will come from their combination. .

The spirit of the workshop

Almost 150 years after its invention by Karl Kahlbaum, catatonia has re-emerged as an independent entity with the official endorsement of the ICD-11 this year. However, it probably neither refers to the same patients, nor to the same phenomena. “Catatonia” and “psychomotricity” are polysemous; they refer to different concepts depending on the paradigmatic framework, e.g. neuropsychiatry, psychological psychiatry, dimensional research domain criteria…
This workshop aims at clarifying some of the major research programs and paradigmatic frameworks in which these phenomena are studied. It will mix philosophy of science, methods, and results, but also clinical symptoms, signs, and examination procedures.
Experts and participants will give their opinion on the same video to objectify some differences in interpretation and definition – participants are welcome to bring questions and clinical material to be discussed. The goal is not to decide who is right or wrong, but to build bridges between different views which might ultimately permit to confront them through crucial experimental series.
This dialectic approach promotes cross-fertilization and ambition to speed-up the discovery process.
