My DS has suspected Aspergers and also meets a lot of the PDA criteria. I am at a loss with him at the moment, we had a very difficult summer and going back to school (y2) has given us some repute but led to no real change in mood.
In a nut shell, we struggle to get him to do anything and everything. Typical weekend involves moping around the house in his pjs until we somehow entice him to get changed (usually before lunch). He often seems bored but is resistant to all our attempts to cheer things up. Eventually, we may succeed in getting him out - a brief trip to the garden centre or visit grandparents for an hour (often with iPad!) The incentive for which is that he can put pjs on when he gets home! Sometimes he really enjoys going out (e.g. Walks were he can go off and explore stuff- pick up sticks and stone etc) and the sense of having achieved something with our day can be amazing. But weirdly, he will sulk and refuse to do the exact same thing (or version of) when we suggest it again the following weekend. And so on it goes.
I find it quite depressing spending so much time at home and having to cajole him for a snatched half hour of life hear and there. It really comes to something when even a treat (e.g. a no pressure trip in the car to the local ice cream farm) gets knocked back.
I'm not sure why I'm posting to be honest. Think I just need to vent!
