Pendant l\u2019\u00e9t\u00e9, les temp\u00e9ratures \u00e9lev\u00e9es<\/strong> enregistr\u00e9es en Espagne comme dans d\u2019autres pays peuvent intensifier les sympt\u00f4mes de diverses maladies neurologiques. Dans notre centre, de nombreux patients atteints de la Maladie du Filum<\/strong>, du syndrome d\u2019Arnold-Chiari I<\/strong><\/a>, de syringomy\u00e9lie idiopathique<\/strong><\/a> et du Syndrome neuro-cr\u00e2nio-vert\u00e9bral<\/strong> signalent une aggravation de leurs sympt\u00f4mes et de leur inconfort lors des \u00e9pisodes de forte chaleur.<\/p>\n

Pourquoi la chaleur peut-elle aggraver les sympt\u00f4mes neurologiques ?<\/h2>\n

De mani\u00e8re g\u00e9n\u00e9rale, la chaleur peut exacerber les sympt\u00f4mes de pathologies neurologiques pr\u00e9existantes. Les temp\u00e9ratures extr\u00eames affectent le cerveau et augmentent les risques, en particulier chez les patients atteints de maladies
\nneurologiques ou psychiatriques, ainsi que chez les enfants, les personnes \u00e2g\u00e9es et les patients souffrant de maladies chroniques.<\/p>\n

L\u2019organisme humain dispose d\u2019un syst\u00e8me de thermor\u00e9gulation<\/strong> qui maintient la temp\u00e9rature corporelle entre 36,7 \u00b0C et 37 \u00b0C. Lorsque la temp\u00e9rature ambiante d\u00e9passe ces valeurs, le corps doit mobiliser davantage de ressources au niveau de l\u2019hypothalamus, la structure responsable de la r\u00e9gulation de la temp\u00e9rature corporelle. Si l\u2019exc\u00e8s de chaleur d\u00e9passe les capacit\u00e9s de compensation de l\u2019organisme, le syst\u00e8me de thermor\u00e9gulation peut perdre de son efficacit\u00e9.<\/p>\n

Le stress thermique<\/strong> peut \u00e9galement alt\u00e9rer la transmission neuronale, favorisant l\u2019apparition de d\u00e9sorientation, de confusion, voire de pertes de connaissance, tout en intensifiant d\u2019autres sympt\u00f4mes neurologiques d\u00e9j\u00e0 pr\u00e9sents.<\/p>\n

La chaleur et le syndrome d\u2019Arnold-Chiari I<\/h2>\n

Chez les patients atteints du syndrome d\u2019Arnold-Chiari I<\/strong>, les c\u00e9phal\u00e9es constituent l\u2019un des sympt\u00f4mes les plus caract\u00e9ristiques. Lors des \u00e9pisodes de forte chaleur, le risque d\u2019augmentation des crises douloureuses est plus \u00e9lev\u00e9, car les temp\u00e9ratures \u00e9lev\u00e9es favorisent la dilatation des vaisseaux c\u00e9r\u00e9braux, provoquant les douleurs pulsatiles caract\u00e9ristiques et limitant davantage les activit\u00e9s quotidiennes.<\/p>\n

Par ailleurs, les difficult\u00e9s \u00e0 trouver un sommeil r\u00e9parateur lorsqu\u2019il fait chaud favorisent l\u2019apparition d\u2019insomnies ou aggravent celles d\u00e9j\u00e0 existantes. Le manque de sommeil constitue \u00e0 son tour un facteur susceptible de d\u00e9clencher de nouvelles crises de migraine.<\/p>\n

Le dysfonctionnement neuronal induit par le stress thermique peut \u00e9galement aggraver la m\u00e9moire, la concentration et l\u2019humeur, des fonctions qui peuvent d\u00e9j\u00e0 \u00eatre alt\u00e9r\u00e9es chez les patients atteints de la Maladie du Filum<\/strong>.<\/p>\n

Temp\u00e9ratures \u00e9lev\u00e9es et syringomy\u00e9lie idiopathique<\/h2>\n

Chez les patients atteints de syringomy\u00e9lie idiopathique<\/strong>, l\u2019exc\u00e8s de chaleur peut intensifier des sympt\u00f4mes tels que la fatigue chronique, les douleurs, les paresth\u00e9sies, la perte de force dans les membres, les difficult\u00e9s de mobilit\u00e9 ainsi que les troubles de la sensibilit\u00e9 thermique et tactile.<\/p>\n

Les temp\u00e9ratures \u00e9lev\u00e9es augmentent la fatigue, aggravent les troubles sensitifs et, associ\u00e9es \u00e0 une transpiration excessive et \u00e0 une atmosph\u00e8re \u00e9touffante, peuvent limiter davantage encore la mobilit\u00e9 et l\u2019autonomie de ces patients.<\/p>\n

Recommandations pour l\u2019\u00e9t\u00e9<\/h2>\n

Comme pour d\u2019autres groupes particuli\u00e8rement vuln\u00e9rables \u00e0 la chaleur, il est recommand\u00e9 pendant les mois d\u2019\u00e9t\u00e9 de :<\/p>\n

    \n
  • Maintenir une hydratation r\u00e9guli\u00e8re.<\/li>\n
  • \u00c9viter toute exposition au soleil pendant les heures les plus chaudes de la journ\u00e9e.<\/li>\n
  • Rester dans des environnements climatis\u00e9s chaque fois que cela est possible.<\/li>\n<\/ul>\n

    Par ailleurs, il est recommand\u00e9 aux patients atteints de pathologies li\u00e9es \u00e0 la Maladie du Filum de planifier leurs d\u00e9placements et leurs activit\u00e9s en veillant \u00e0 \u00eatre accompagn\u00e9s, afin d\u2019\u00e9viter de se retrouver seuls en cas d\u2019aggravation des sympt\u00f4mes en dehors d\u2019un environnement s\u00fbr et climatis\u00e9.<\/p>\n

    Apr\u00e8s le traitement par le Filum System\u00ae<\/h2>\n

    \u00c0 la suite de l\u2019intervention r\u00e9alis\u00e9e selon la m\u00e9thode Filum System\u00ae<\/strong>, pratiqu\u00e9e par l\u2019\u00e9quipe du Dr Miguel B. Royo Salvador \u00e0 l\u2019Institut Chiari & Syringomy\u00e9lie & Scoliose de Barcelone chez des patients atteints du Syndrome neuro-cr\u00e2nio-vert\u00e9bral<\/strong>, parmi les nombreuses am\u00e9liorations observ\u00e9es chez plus de 2 500 patients op\u00e9r\u00e9s, des modifications de la thermor\u00e9gulation et de la circulation ont \u00e9galement \u00e9t\u00e9 constat\u00e9es chez une partie de nos patients au cours de la p\u00e9riode postop\u00e9ratoire.<\/p>\n

    Par ailleurs, des sympt\u00f4mes tels que les c\u00e9phal\u00e9es, l\u2019insomnie, les troubles cognitifs ou de l\u2019humeur, la fatigue chronique, la perte de force, la douleur et les troubles de la mobilit\u00e9 peuvent s\u2019att\u00e9nuer, voire dispara\u00eetre, apr\u00e8s le traitement. Par cons\u00e9quent, certains patients pr\u00e9sentent une moindre vuln\u00e9rabilit\u00e9 face aux temp\u00e9ratures \u00e9lev\u00e9es.<\/p>\n
