We had this. It was related to avoiding stuff she regarded as unpleasant (anything from a telling off, to studying when she didn't want to etc. etc.).
Eventually I realised that she was not thinking beyond the moment, and lying or failing to communicate made it go away. She was not associating this with it coming back twice as bad further down the line.
Because I wasn't understanding that, it got worse and worse. And I wasn't being clever enough to relating cause and effect.
Unfortunately for some time I was bringing pressure to bear to try to force her to change, so I became one of the things she would say anything to get rid of for 24hrs.
Ultimately I worked it out, and so I introduced a gap - complex to explain but basically down to "you can get away with pretty much anything as long as you tell me straight away. If, however, I find out about it myself then the wrath of the Gods etc. etc".
And then living by my words, which was less than easy I can tell you. In her mind this then became that the way to make stuff go away was to tell me about it, rather than to hide it. But I had to live with being told stuff I didn't really want to deal know, and dealing with things differently.
For example, "Dad, I got into trouble today for not doing my homework last week", I had to reward the telling me about the trouble, and for the moment let the "not doing my homework" go.
It was a slow process, but momentum did pick up. That started resolving the first bit, which was getting the communication going.
Then it was trying to establish the link that addressing something today was less effort and badness than suffering a train wreck tomorrow. This included allowing her to use levels of effort. This will be bad if it goes wrong, work to avoid it, this will be merely irritating if it goes wrong so don;t worry about it". That was more trying, but some progress was made.
Then I started introducing rewards which were over the top for the achievement, but were related to how forward thinking she had been. And these were rewards like going out somewhere, or cinema, or books or anything else that a) she wanted and b) was constructive in my opinion. I refused any requests for rewards which I didn't approve of.
I don't buy the ADD bit, but I do think its related to the strong personality and the intelligence.
Like a balloon, squeeze it somewhere and it pops out somewhere else. Its just making it pop in the right place, because its going to pop out whatever.
Its still a bit of an effort, but 12 months later its like night and day.
Re-reading this it is quite clearly not a very clear explanation, but for us it worked. Perhaps you can pick some bones out of it.
