Utilizando espetroscopia de resson\u00e2ncia magn\u00e9tica nuclear, demonstrou que os resultados eram diferentes e distintos para cada um dos tr\u00eas grupos, sendo a urina das crian\u00e7as autistas marcadamente diferente da urina das crian\u00e7as saud\u00e1veis e n\u00e3o relacionadas. O cientista atribuiu estas diferen\u00e7as \u00e0s diferentes bact\u00e9rias encontradas nas crian\u00e7as autistas. Entre outras coisas, estas segregam N-metil-nicotinamida (NMND), que provavelmente perturba o desenvolvimento do c\u00e9rebro. A descoberta pode apoiar a hip\u00f3tese de que as subst\u00e2ncias segregadas pelas bact\u00e9rias presentes no intestino podem contribuir para a doen\u00e7a, que \u00e9 frequentemente acompanhada por perturba\u00e7\u00f5es metab\u00f3licas, sintomas como dores abdominais ou diarreia e altera\u00e7\u00f5es da flora fecal. Entretanto, Derrick Mc Fabre, da Universidade de Western Ontario, no Canad\u00e1, descobriu que os \u00e1cidos gordos de cadeia curta produzidos pelas bact\u00e9rias clostridium podem causar altera\u00e7\u00f5es revers\u00edveis, semelhantes \u00e0s do autismo, no comportamento e na bioqu\u00edmica cerebral dos ratos. A confirma\u00e7\u00e3o dos resultados dos estudos canadianos e brit\u00e2nicos exigir\u00e1 mais trabalho &#8211; talvez atrav\u00e9s de an\u00e1lises \u00e0 urina seja poss\u00edvel detetar o autismo mais cedo do que antes (atualmente \u00e9 poss\u00edvel aos 2-3 anos de idade). Quanto mais precoce for o diagn\u00f3stico, mais eficaz ser\u00e1 o tratamento, tamb\u00e9m no caso do autismo.
