Persistent Vegetative State

People with severe brain injuries sometimes emerge from a coma awake but unresponsive, leaving families with painful questions. Are they aware? Can they think and feel? Do they have any chance of recovery?

A new study has found that PET scans may help answer these wrenching questions. It found that a significant number of people labeled vegetative had received an incorrect diagnosis and actually had some degree of consciousness and the potential to improve. Previous studies using electroencephalogram machines and M.R.I. scanners have also found signs of consciousness in supposedly vegetative patients.

“I think these patients are kind of neglected by both medicine and society,” said Dr. Steven Laureys, an author of the new study and the director of the Coma Science Group at the University of Liège in Belgium. “Many of them don’t even see a medical doctor or a specialist for years. So I think it’s very important to ask the question, are they unconscious?”

In the United States, 100,000 to 300,000 people are thought to be minimally conscious, and an additional 25,000 are vegetative. In Belgium, the combined incidence of the two conditions is about 150 new cases per year, Dr. Laureys said.

An article about the new research was published on Tuesday in The Lancet.

Dr. Laureys and his colleagues studied 122 patients with brain injuries, including 41 who had been declared vegetative — awake but with no behavioral signs of awareness. People who are vegetative for a year are thought to have little or no chance of recovering, and the condition can become grounds for withdrawing medical treatment. Terri Schiavo, in a vegetative state for 15 years, died in 2005 in Florida after courts allowed the removal of her feeding tube. Continue reading

Oops, Guess He Was Not In A Persistent Vegetative State!

Ron Houben was paralyzed and trapped in his own body for 23 years.  Doctors labeled him as being in a coma and in a persistent vegetative state.  As the Mail Online reports, they were gravely in error:

Rom Houben, trapped in his paralysed body after a car crash, described his real-life nightmare as he screamed to doctors that he could hear them – but could make no sound.

‘I screamed, but there was nothing to hear,’ said Mr Houben, now 46, who doctors thought was in a persistent vegetative state.

Three years ago new high-tech scans revealed that his brain was functioning normally.

His case has only just been revealed in a scientific paper released by the man who ‘saved’ him, top neurological expert Dr Steven Laureys.

‘Medical advances caught up with him,’ said Dr Laureys, who believes there may be many similar cases of false comas around the world.

Dr Laureys’s new study claims that patients classed as in a vegetative state are often misdiagnosed.

‘Anyone who bears the stamp of “unconscious” just one time hardly ever gets rid of it again,’ he said.

The doctor, who leads the Coma Science Group and Department of Neurology at Liege University Hospital, found Mr Houben’s brain was still working by using state-of-the-art imaging.

He plans to use the case to highlight what he considers may be similar examples around the world. Continue reading
