"Of course people have abused DLA." But how?
The only thing I can think is that the department have in the past been putting people on lifetime awards because the cost of reassessing everyone all the time is so great. And a small % of these have miracle cures, and an even smaller % of those don't tell the department about it and carry on getting paid benefit.
But it still seems implausible. DD1 has only got 1/3 of a working brain, and that's permanent. She gets reassessed every 3 years. Total waste of time and money, and tbh I imagine we waste more money on reassessments where it's clearly unnecessary than we lose through fraudulent claims.
