Es tracta d&#8217;un trastorn que pateix entre l&#8217;1 i el 3% de la poblaci\u00f3, la majoria dels quals s\u00f3n pacients cr\u00f2nics. Tot i aix\u00f2, l&#8217;impacte d&#8217;aquesta malaltia es pot minimitzar molt amb la prevenci\u00f3 i la detecci\u00f3 preco\u00e7.<\/p>\n<p>Un <a href=\"https:\/\/idibell.cat\/recerca\/area-de-neurociencies\/programa-de-neurociencies\/psiquiatria-i-salut-mental\/\">equip de recerca<\/a> del programa de neuroci\u00e8ncies de l&#8217;IDIBELL i de l&#8217;Hospital Universitari de Bellvitge, liderat pel Dr. Carles Soriano-Mas, tamb\u00e9 membre del CIBER de Salut Mental (CIBERSAM), ha identificat <strong>dos gens associats amb el comportament anormalment reverberant dels circuits cerebrals implicats al TOC<\/strong>.
