The official definition is...
"an impairment or immaturity of the organisation of movement. It is an immaturity in the way that the brain processes information, which results in messages not being properly or fully transmitted."
With two supposed aspects..
Ideational dyspraxia: difficulty with planning a sequence of coordinated movements.
Ideo-Motor dyspraxia: difficulty with executing a plan, even though it is known.
Though I will also say there are other aspects to the condition, such as hyper or hypo sensitivity to sound, touch, taste etc. Some will have this, some won't.
Personally I can't go clubbing because the bass makes my head feel horrible and makes me physically throw up. I went to my GP about it, he diagnosed me with some fancy term, though since that I've read that hypersensitivity to sound can be part of dyspraxia. As a child loud noises always made me cry, even just an ambulance or fire engine with its sirens on going past, my mum used to try and avoid roadworks because they'd make me cry or ages, also any raised voices would make me cry. With the latter...I find that still is the case, though it could be more some issue to do with anger, if someone is angry at me, I get upset incredibly easily, I can't have an argument, if it involves raised voices, because of this.
So yeah, I suppose it can impact anything and it seems quite changeable depending on each individual case, though main features like clumsiness with fine motor skills are standard. It's why I don't like bringing up that I have it, because anyone could look at the huge symptoms list and pick out a few things which apply to them. I don't like to make a big deal out of it tbh, I'm just the clumsy one.
