I don't know exactly what the DSM covers, but when I was diagnosed it was partly via a 'RAADS-R' test, on which I scored 204. According to the psychiatrist who carried out the test, that was "one of the highest scores" she had ever seen. I live in Scotland, so I don't know if we use something slightly different to some of the other countries in the EU.

Actually, I just had a quick search for some information and apparently this is unlikely to affect countries in the UK because we tend to use the WHO's ICD instead of the DSM, which is only more commonly used in America. This explains why I was diagnosed with 'Aspergers' after the updated DSM release in May 2013.
