Genève, 2 mai - L'hypothèse d'un lien entre la vaccination rougeole et l'autisme a été lancée en 1998 par Wakefield. Des millions de dollars ont été investis pour étudier cette hypothèse effrayante. Le verdict est tombé en 2001: il n'y a aucune évidence scientifique soutenant cette hypothèse. Si la vaccination était une cause d'autisme, le nombre d'autistes augmenterait lorsque la vaccination est

(Agence Science-Presse) On croyait la controverse sur l’autisme morte, eh bien la voilà qui resurgit par la façade politique. Maintes fois avancé, le lien entre vaccination et autisme constitue un mythe. Toutes les hypothèses qui ont été proposées, comme la présence de mercure, se sont révélées, après examens, sans fondements. Or, voilà que le gouvernement américain rallume le feu. Au début du

BBC News Children with autism do not appear to leak damaging proteins from their intestines, a study into the so-called "leaky gut" theory has suggested. It has been claimed autistic children cannot fully digest proteins found in many foods - and that the resulting peptides escape and affect the brain. But UK researchers found children with autism did not have more peptides in their urine than

Sarah Boseley, The Guardian There is no evidence to link the MMR vaccination to autism in children, according to a substantial new study published today. In the biggest review conducted to date, scientists from Guy's Hospital in London, Manchester University and the Health Protection Agency, analysed the blood from 250 children and concluded that the vaccine could not be responsible.

Scientists have discovered how mutations in two key proteins may lead to autism. They have shown one protein increases the excitability of nerve cells, while the other inhibits cell activity. The University of Texas team found that in normal circumstances the proteins balance each other out. But the study, published in Neuron, suggests that in people with autism the balance between the

EDITORIAL La sensibilité des parents d'enfants avec autisme aux rumeurs est compréhensible. Toute explication, même irrationnelle, est bonne pour ceux qui subissent un mal qui frappe apparemment à l'aveugle. C'est une tendance naturelle de l'homme à projeter du sens dans ce qui nous entoure. Le processus n'est donc pas nouveau: avant l'ère scientifique, on imaginait un panthéon de dieux,

Science Daily — University of Iowa researchers have learned more about a genetic mutation that contributes to autism. The mutation occurred in sperm cells of a father, who does not have autism, but passed the condition on to two of his children. The investigators now know more about how the mutation causes problems with a specific gene and are testing for additional mutations of the same gene in

SAN DIEGO, May 4 (UPI) -- U.S. researchers say infants who have older siblings with autism often fail to seek emotional cues from adults as other toddlers would.

New research indicates that young children with autism have a difficult time recognizing ordinary words and more of their brains are occupied with this kind of task compared to typically developing youngsters. “Rather than becoming an expert in recognizing words, their brains slow down,” said Patricia Kuhl, co-director of the University of Washington’s Institute for Learning and Brain Sciences
