If your local children's hospital doesn't have a neuropsychologist, I'd find the next largest one up the chain. However we had to dig a bit - best thing is to call the hospital and ask for psychiatry and then ask THEM about it. So the local one might, it's a question of who you get on the phone!
That said, our closest kids' hospital doesn't have a decent psychiatric dept so we went to the next big city. 
And they're great.
