Link since no one else has bothered!
Anyway... having just read the link... I don't think his case against the NHS will go very far, unfortunately. Mainly because this happened in Sweden...
Other than that, it is a horrific yet surprisingly common story - did anyone see the Louis Theroux docu on End of Life care in the US last Sunday? One of the cases involved in that he followed, was a young College student who basically messed himself up with a party-drug overdose, he was totally unresponsive and the family were told repeatedly that there was no chance of recovery. At one point, they were filming a supposedly "top neurosurgeon" who was looking at scans and said he would most likely never wake up, and if he did he would be in a persistent vegetative state... his family (mainly his sister) refused to give up hope and then by the end of them following it, he was starting to show slight signs of life

.
At the end they had a brief follow-up where Louis went back, and the guy was up and walking around, talking and joking, shook his hand etc. WTF is that?? They had seemed SO sure, we were watching it saying "what a shame, his sister is in total denial".
