Why can't the duodopa be approved instead of the brain surgery?

They drilled my head and I'm still taking 1500 mg of levodopa a day! I'd much rather have the pump!! And why the heck is this treatment which is so effective being squandered on those in nursing homes! Think of those that this could help get back on their feet and be productive with a lot of life ahead of them, NOPE I cannot see how this is more expensive than brain surgery-perhaps in the long run (drug costs,etc) but come on, initially?? I smell a rat!! I'm up way too late and tommorrrow is another day. Let''''s face it this healthcare thing is never going to be fixed. It's too dollar hungry with special interests. Nite ya'll.
