Darth DSM-5 and autism

Blue Harvest @ Wikipedia @ Family Guy
I need to create a suitable atmosphere for this post, so try this music for size and think Blue Harvest...

Right. The wait is over. The discussions / arguments / objections / agreements are all confined to history. Drum roll, spotlight centre-stage... enter DSM-5 and into unknown territory we all go, particularly with autism, sorry.. autism spectrum disorders (ASDs) in mind.

As you can see from the link above to the new diagnostic guidelines from the American Psychiatric Association (APA) the diagnosis of autism has, as was widely anticipated, changed somewhat to encompass quite a few adaptations (see this previous post).

I'm not saying too much more on this at the present time, bearing in mind 'spectrum' is a word which seems to get more of a mention in this revision of the DSM; and not just with autism in mind (see here and here*).

Obviously things aren't going to just change overnight with DSM-5 as it is eventally rolled out. Clinicians will need to learn some new diagnostic brushstrokes. Remember too that DSM is only one part of the diagnostic manuals currently in use (although even ICD is subject to revision in coming years already mentioning something called Social Reciprocity Disorder?). That being said, the implications of DSM-5 on issues like the autism numbers game - same as what happened across previous versions - are probably going to be subject to some pretty intense scrutiny over the coming years.

Don't also be under any disillusion that the new changes are going to herald any giant leaps forward in autism research anytime soon. Interestingly, Dr Tom Insel, head of the US National Institute of Mental Health (NIMH) was recently quoted as saying that "NIMH will be re-orienting its research away from DSM categories", reported also by other authors** (open-access). In other words, even with the fresh smell of new DSM in the air, a new 'nosology' is already planned.

To close, Peter 'Han Solo' Griffin on TIE fighters... dan-dan-da-dan, da-da-dan-dan-dan...
