[Organic troubles with psychiatric symptoms: What is the appropriate childhood and adolescence psychiatric care? Reflections on disimmune encephalitis cases]. / Troubles organiques à expression psychiatrique, quel soin pédopsychiatrique ? Réflexions autour de cas d'encéphalites dysimmunitaires.

Organic mental disorders are different and further revealed by increasingly advanced research. They are nevertheless misunderstood, without consensus, and raise clinical, diagnostic, and therapeutic questions. These disorders require effective collaboration between practitioners such as pediatricians and child psychiatrists. The subject should not disappear behind the complexity related to the clinical expression of these symptoms. Based on three cases of autoimmune encephalitis, we offer a reflection on the management and assessment of these diseases by a multidisciplinary team with the intention of providing optimal management. The aim of this paper is to override an initial divide posed by a particular clinical presentation. We would like to shed light on the place and legitimacy of child psychiatrists and their clinical expertise. This does not exclude the need for care of the symptoms, considering each subject and her experience. Follow-up is necessary because of the possible, often traumatic, functional and psychological consequences. Finally, the presence of each professional should be specified when the psychiatric symptoms appear to be the result of an organic disease in order to better support the subject in his suffering body.
