Les femmes \u00e2g\u00e9es sont plus susceptibles de donner naissance \u00e0 des enfants autistes<\/a>, mais le risque n’est plus \u00e9lev\u00e9 pour les p\u00e8res \u00e2g\u00e9s que si la m\u00e8re est jeune, rapportent des chercheurs am\u00e9ricains dans la revue Autism Research.<\/p><\/blockquote>\n

Le risque qu’une femme de 40 ans donne naissance \u00e0 un enfant autiste est 50 % plus \u00e9lev\u00e9 que pour une femme \u00e2g\u00e9e de 25 \u00e0 29 ans, selon des chercheurs de l’universit\u00e9 de Californie, qui ont d\u00e9cid\u00e9 d’examiner les donn\u00e9es concernant pr\u00e8s de 5 millions d’enfants et 12 159 cas d’autisme. Pour les p\u00e8res, le risque n’est aussi \u00e9lev\u00e9 que si la m\u00e8re a moins de 30 ans.<\/p>\n

Il s’agit d’autres \u00e9tudes portant sur l’association entre l’\u00e2ge des parents et l’autisme de la prog\u00e9niture. Elles contrastent avec les r\u00e9sultats d’une \u00e9tude men\u00e9e en 2006 en Isra\u00ebl. \u00c0 l’\u00e9poque, leurs auteurs avaient sugg\u00e9r\u00e9 que les enfants d’hommes de plus de 40 ans \u00e9taient jusqu’\u00e0 six fois plus susceptibles de d\u00e9velopper un autisme.<\/p>\n

Compte tenu du nombre croissant d’enfants autistes<\/strong> aux \u00c9tats-Unis, l’accent est mis sur l’identification des facteurs susceptibles de contribuer aux sympt\u00f4mes.<\/p>\n

Ces recherches sont men\u00e9es, entre autres, par le Dr Irva Hertz-Picciotto, qui explique que plus un parent est \u00e2g\u00e9, plus les toxines se sont accumul\u00e9es dans son organisme. Ces toxines, \u00e0 leur tour, ne restent pas insensibles aux ovules et aux spermatozo\u00efdes. En outre, les m\u00e8res plus \u00e2g\u00e9es sont plus susceptibles de souffrir de maladies auto-immunes et sont plus sujettes au diab\u00e8te gestationnel. Le Dr Hertz-Picciotto souligne \u00e9galement que les parents plus \u00e2g\u00e9s sont plus susceptibles d’avoir des ant\u00e9c\u00e9dents de traitement de l’infertilit\u00e9. Tous ces facteurs peuvent influencer le d\u00e9veloppement de l’autisme chez un enfant<\/strong>.<\/p>\n

Outre l’\u00e2ge des parents, les chercheurs examinent un large \u00e9ventail de facteurs environnementaux. Ils tiennent \u00e9galement compte des infections pass\u00e9es, des traitements, du r\u00e9gime alimentaire et des suppl\u00e9ments pris, entre autres. Les sp\u00e9cialistes de l’Institut national am\u00e9ricain de la sant\u00e9 mentale ont, quant \u00e0 eux, l’intention de s\u00e9quencer le g\u00e9nome de centaines d’enfants et de leurs parents dans un avenir proche afin d’en savoir plus sur la base g\u00e9n\u00e9tique des troubles autistiques<\/strong>.<\/p>\n
