how can there diagnosis my 6year old without ados

As I understand it, a test such as ADOS will show whether an individual has got an autistic spectrum disorder. Having an ASD is a bit like having a broken leg or being pregnant - you either have the condition or you don't - you can't have half a broken leg or be half pregnant. The difficulties that an individual has are then determined by whether the person also has other conditions e.g. low intelligence or sensory issues. ASD people often struggle to show their intelligence - your son may not co-operate with the testing process and may score badly in a test but it doesn't necessarily mean that he is not intelligent.

Have you got him on a good clean diet that is free of orange colour additives etc? Some ASD people are extra sensitive to the food they eat and can benefit from changing the things they eat. Have a look at fedup.com.au/.../introduction-to-food-intolerance-3
