http://www.msnbc.msn.com/id/34109227/ This is a fascinating article. This poor guy was aware of everything going on for 23 years, yet was unable to talk or move to let anyone know. From the article: Despite the importance of diagnostic accuracy, the rate of misdiagnosis of vegetative state has not substantially changed in the past 15 years, the study said. Back then, studies found that up to 43 percent of patients with disorders of consciousness are erroneously assigned a diagnosis of vegetative state. and this: It makes you think. There is still a lot of work to be done to better diagnose such disorders, said Caroline Schnakers of the Coma Science Group. My own son suffered a catastrophic respiratory failure two years ago, leading to a heart attack and stroke. He was in coma for about a week, with us being told there was "no brain activity" on day 2. That kid just got home from work!
