\"anxi\u00e9t\u00e9,<\/p>\n

Une petite \u00e9tude isra\u00e9lienne a montr\u00e9 que l\u2019oxyg\u00e9noth\u00e9rapie hyperbare pouvait r\u00e9duire les effets de stress post-traumatique.<\/p>\n

Les r\u00e9sultats de l\u2019essai randomis\u00e9 et men\u00e9 entre mars 2018 et avril 2019 ont \u00e9t\u00e9 revus par les pairs et publi\u00e9s le 22 f\u00e9vrier dans la publication scientifique Plos one<\/em><\/a>. La recherche a \u00e9t\u00e9 men\u00e9e par l\u2019Universit\u00e9 de Tel Aviv en coop\u00e9ration avec le Centre m\u00e9dical Shamir, un h\u00f4pital public d\u2019Isra\u00ebl.<\/p>\n

Le trouble de stress post-traumatique (TSPT) est un trouble de l\u2019anxi\u00e9t\u00e9<\/a> qui peut survenir chez les personnes qui ont v\u00e9cu ou \u00e9t\u00e9 t\u00e9moins d\u2019un \u00e9v\u00e9nement traumatique.<\/p>\n

L\u2019\u00e9quipe a test\u00e9 le traitement \u00e0 l\u2019oxyg\u00e8ne sur 18 d\u2019anciens militaires v\u00e9t\u00e9rans souffrant de TSPT pour qui les m\u00e9dicaments et la psychoth\u00e9rapie s\u2019av\u00e9raient inefficaces. Un autre groupe de 17 v\u00e9t\u00e9rans pr\u00e9sentant des conditions similaires a servi de groupe t\u00e9moin.<\/p>\n

\u00c0 l\u2019issue de l\u2019oxyg\u00e9noth\u00e9rapie en chambre pressuris\u00e9e, la moiti\u00e9 des patients n\u2019\u00e9taient plus consid\u00e9r\u00e9s comme souffrant de TSPT. Le traitement consistait en 60 s\u00e9ances effectu\u00e9es quotidiennement, cinq fois par semaine.<\/p>\n

La m\u00e9decine hyperbare n\u2019est g\u00e9n\u00e9ralement pas utilis\u00e9e pour soigner le stress post-traumatique. Elle est cependant administr\u00e9e aux personnes souffrant d\u2019empoisonnement au monoxyde de carbone comme les pompiers ou les mineurs, des cas de gangr\u00e8ne et d\u2019infections dans lesquelles les tissus manquent d\u2019oxyg\u00e8ne. Les plongeurs qui subissent un accident de d\u00e9compression peuvent \u00e9galement \u00eatre trait\u00e9s par l\u2019oxyg\u00e9noth\u00e9rapie hyperbare.<\/p>\n

Les patients se rendent dans un caisson dont la pression est sup\u00e9rieure \u00e0 la moyenne atmosph\u00e9rique et respirent de l\u2019oxyg\u00e8ne pur, \u00e9vitant ainsi que les tissus ne meurent par manque d\u2019oxyg\u00e8ne.<\/p>\n

Les traumatismes modifient la structure et le fonctionnement du cerveau<\/h2>\n

La nouveaut\u00e9 est cette approche physiologique du traitement du trouble de stress post-traumatique.<\/p>\n

En effet, les traumatismes provoquent des alt\u00e9rations durables de l\u2019activit\u00e9 c\u00e9r\u00e9brale et de la structure du cerveau. D\u2019une certaine mani\u00e8re, l\u2019oxyg\u00e9noth\u00e9rapie a cherch\u00e9 \u00e0 r\u00e9parer les l\u00e9sions c\u00e9r\u00e9brales.<\/p>\n

\u00ab\u202fNous avons cherch\u00e9 \u00e0 traiter le TSPT de mani\u00e8re \u00e0 agir sur les changements physiques r\u00e9els dans le cerveau\u202f\u00bb<\/em>, a d\u00e9clar\u00e9 au Times of Israel<\/em><\/a> la Dr. Keren Doenyas-Barak, membre de l\u2019\u00e9quipe \u00e0 l\u2019origine de l\u2019\u00e9tude.<\/p>\n

Apr\u00e8s la th\u00e9rapie, les sympt\u00f4mes associ\u00e9s au TSPT et les r\u00e9sultats de l\u2019imagerie par r\u00e9sonance magn\u00e9tique (IRM) du cerveau se sont tous les deux am\u00e9lior\u00e9s. Apr\u00e8s une s\u00e9ance d\u2019oxyg\u00e9nation, l\u2019\u00e9tude a montr\u00e9 une augmentation de l\u2019activit\u00e9 c\u00e9r\u00e9brale du lobe frontal, r\u00e9gion responsable de la r\u00e9gulation des \u00e9motions, et de l\u2019hippocampe, qui joue un r\u00f4le important dans la m\u00e9moire (des dommages \u00e0 l\u2019hippocampe peuvent \u00eatre la cons\u00e9quence d\u2019un manque d\u2019oxyg\u00e8ne).<\/p>\n

Selon l\u2019\u00e9tude, l\u2019oxyg\u00e9nation c\u00e9r\u00e9brale activerait la neuroplasticit\u00e9, c\u2019est-\u00e0-dire la capacit\u00e9 du r\u00e9seau neuronal du cerveau \u00e0 se modifier et, par cons\u00e9quent, \u00e0 gu\u00e9rir des blessures dues \u00e0 un traumatisme.<\/p>\n

Sept sujets trait\u00e9s par l\u2019oxyg\u00e9nation ont m\u00eame fait appara\u00eetre de nouveaux souvenirs de l\u2019\u00e9v\u00e9nement traumatique au cours de la seconde moiti\u00e9 du traitement. Pour l\u2019un d\u2019entre eux, le souvenir est m\u00eame apparu brusquement sous forme de flash-back, indique l\u2019\u00e9tude. Cette r\u00e9cup\u00e9ration de la m\u00e9moire \u00e9tait inattendue pour les chercheurs.<\/p>\n

Cependant, le groupe t\u00e9moin savait qu\u2019il n\u2019avait pas subi l\u2019oxyg\u00e9noth\u00e9rapie, \u00e9tant donn\u00e9 la nature du traitement, ce qui peut affecter les r\u00e9ponses au questionnaire et les r\u00e9sultats de l\u2019IRM. L\u2019autre principale limite de l\u2019\u00e9tude est la taille tr\u00e8s r\u00e9duite de l\u2019\u00e9chantillon, qu\u2019il faudrait \u00e9largir avant de tirer des conclusions plus affirm\u00e9es.<\/p>\n
