Un artículo publicado en "The Lancet" por investigadores británicos concluye que la cifra de casos de autismo y trastornos relacionados en el Reino Unido es el doble de lo que se pensaba.
El nuevo estudio indica que 116 de cada 10.000 niños británicos presentan autismo o trastornos relacionados, cuando la cifra estimada anteriormente era de 44 por 10.000.
No obstante, los autores, del Guy's and St. Thomas' Hospital de Londres, señalan que se desconoce si esa prevalencia más elevada se debe a una mejor detección de casos, a una ampliación de los criterios diagnósticos o a un auténtico aumento de la incidencia.
Los investigadores calcularon la prevalencia analizando casos de autismo y trastornos de espectro autista en niños de 9 y 10 años del sur de Londres en 2001. Las cifras, concretamente, muestran 39 casos de autismo por cada 10.000 niños y 77 casos de trastornos de espectro autista por cada 10.000.
