Vegetative patient Scott Routley says 'I'm not in pain'
A
Canadian man who was believed to have been in a vegetative state for
more than a decade, has been able to tell scientists that he is not in
any pain.
It's the first time an uncommunicative, severely
brain-injured patient has been able to give answers clinically relevant
to their care.Scott Routley, 39, was asked questions while having his brain activity scanned in an fMRI machine.
His doctor says the discovery means medical textbooks will need rewriting.
Vegetative patients emerge from a coma into a condition where they have periods awake, with their eyes open, but have no perception of themselves or the outside world.
Mr Routley suffered a severe brain injury in a car accident 12 years ago.
None of his physical assessments since then have shown any sign of awareness, or ability to communicate.
But the British neuroscientist Prof Adrian Owen - who led the team at the Brain and Mind Institute, University of Western Ontario - said Mr Routley was clearly not vegetative.

"Scott has been able to show he
has a conscious, thinking mind. We have scanned him several times and
his pattern of brain activity shows he is clearly choosing to answer our
questions. We believe he knows who and where he is."
Prof Owen said it was a groundbreaking moment."Asking a patient something important to them has been our aim for many years. In future we could ask what we could do to improve their quality of life. It could be simple things like the entertainment we provide or the times of day they are washed and fed."
Scott Routley's parents say they always thought he was conscious and could communicate by lifting a thumb or moving his eyes. But this has never been accepted by medical staff.
Prof Bryan Young at University Hospital, London - Mr Routley's neurologist for a decade - said the scan results overturned all the behavioural assessments that had been made over the years.

FMRI SCANNING
- Functional Magnetic Resonance Imaging measures the real-time activity of the brain by tracking the flow of oxygen-rich blood
- The patients were repeatedly asked to imagine playing tennis or walking around their home
- In healthy volunteers each produces a distinct pattern of activity, in the premotor cortex for the first task and the parahippocampal gyrus for the second
- It allowed the researchers to put a series of yes or no questions to severely brain-injured patients. A minority were able to answer by using the power of thought
- In 2010 Prof Owen published research showing that nearly one in five of the vegetative patients were able to communicate using brain activity
"I was impressed and amazed that
he was able to show these cognitive responses. He had the clinical
picture of a typical vegetative patient and showed no spontaneous
movements that looked meaningful."
Observational assessments of Mr Routley since he responded in
the scanner have continued to suggest he is vegetative. Prof Young said
medical textbooks would need to be updated to include Prof Owen's
techniques.The BBC's Panorama programme followed several vegetative and minimally-conscious patients in Britain and Canada for more than a year.
Another Canadian patient, Steven Graham, was able to demonstrate that he had laid down new memories since his brain injury. Mr Graham answers yes when asked whether his sister has a daughter. His niece was born after his car accident five years ago.
The Panorama team also followed three patients at the Royal Hospital for Neuro-disability (RHN) in Putney, which specialises in the rehabilitation of brain-injured patients.
It collaborates with a team of Cambridge University neuroscientists at the Wolfson Brain Imaging Centre at Addenbrooke's hospital, Cambridge.

A second patient, who had not been fully assessed by the RHN, is shown to have some limited awareness in brain scans.
