There was an article on the Grauniad, a few years back, written by someone who had dyspraxia. I was rather concerned to see that I had some of the symptoms, albeit of an extremely mild nature, namely: I'm a bit clumsy (though don't suffer from involuntary movements, apart form having restless feet -- currently (and, I hope, temporarily) made worse by my diabetes -- and the usual thing of sometimes wanting to move a limb suddenly when I've been sitting or lying down awkwardly); iffy short-term memory (which means that I find myself checking that doors are locked more than once in a row** ***).
I'm of the opinion that "my dyspraxia" (which is nothing of the sort) is either a demonstration that dyspraxia is a spectrum condition (meaning that
everyone is somewhere on the spectrum) or just another example of the way we like to have names for the things we have and do, even if the names are associated with medical conditions; even if we're misapplying the names we've found after a minimal amount of googling (or reading a Grauniad article) and a failure to understand properly what a condition really is.
EDIT: Anyway, to say what I meant to say when I first replied -- but forgot -- is that
- apart from some initial "scene setting" (i.e. subtly letting us know something about the character) you shouldn't go overboard with the incidents of symptoms, but stick to occasions when it impacts what is happening
- the character lives with the condition and its symptoms, so he (or she) will treat it as part of his (or her) everyday existence, i.e. most of the time it is literally unremarkable.
** - I suspect that most of this palaver is more OCD-ish type behaviour, triggered by the general overall feeling that I may have forgotten to lock a door rather than any real suspicion that I haven't.
*** - The worst example was the car. Okay, because I always lock with the key fob remote, not the key itself, I could lock it "again" from a distance, but I'm sure this behaviour is what kept draining the battery, requiring over-frequent changes. Thankfully, my current car "closes" the wing mirrors on locking, so now I have a visual clue that I've locked the car.
