actually there is. Go over to the local nursing home and take a peek at somebody's who's "locked in " by a brain-stem stroke. Ask how they're doing today, of course they won't be able to say much , but the rolling of their eyeballs might tell what you need to learn. Or find somebody with a progressive malignancy and a terminal diagnosis, or severe Parkinson's Disease, who's shaking like a leaf not able to get up without falling, having to depend on an over-worked staff to lift them out their feces-packed diaper; and whose medication, by the way (dopamine active) may be causing them to hallucinate about small children in the hallway. Then ask somebody with this horrific akathisia that you speak of, how they are, and they're likely to reply, "not too bad ,Doc, do you have a smoke?" Certainly then, you should go on to ask them, why can't you sit still, or have you noticed you seem to be marching in place? But of course, you'd find the MD out to lunch with the pharmaceutical representative, because that's the kind of people that go into medicine, they're more interested in that ham sandwich than they are in the well-being of their patients.
