Researchers: Woman's Severely Damaged Brain Responds To Directions
By Dave Reynolds, Inclusion Daily Express

CAMBRIDGE, ENGLAND--Researchers using new brain imaging technology are opening a window into the awareness levels of people with the most severe of brain injuries, and providing hope that they will someday be able to communicate with others. Their research is also casting doubt on the accuracy of the 'vegetative state' diagnosis.

For a report published this month by the journal Science, neuroscientist Dr. Andrew Owen, head of Cambridge University's Medical Research Council Cognition and Brain Sciences Unit, used functional magnetic resonance imaging (fMRI) to scan the brain of a 23-year-old woman who has been diagnosed in a "vegetative state" since she was injured in a July 2005 car accident.

For months, doctors said the woman was unresponsive, that she could not follow instructions, nor could she focus her eyes or track a person or object around the room with her eyes.

Dr. Owen scanned the woman's brain with fMRI technology while asking her to imagine herself playing tennis and walking around her house. The parts of the woman's brain that before her injury would have controlled body movements lit up as if she were actually performing the tasks. Owens then scanned the brains of a dozen people whose brains were not injured, and found that the same areas of their brains were activated when they were asked to imagine the same tasks.

Owen said the woman fit all of the clinical criteria for being in a vegetative state.

"What we have developed is a method for detecting when someone is aware in the absence of other clinical evidence," he said.

Owen and other scientists were quick to point out that fMRI imaging would not have helped Terri Schiavo, who died of dehydration last year after her feeding tube was removed at her husband's request. Many doctors and Schiavo's husband insisted that Terri's brain was heavily damaged when she stopped breathing for several minutes in February 1990. Terri's parents fought to keep her alive, arguing that she responded to them by laughing, following balloons with her eyes, and trying to speak to them. They unsuccessfully battled through the courts for tests that they believed would show that she was aware of her surroundings, and for therapies that they said might have helped her to regain some of her abilities, such as speaking or swallowing.

In February of 2005, about a month before Schiavo died, disability rights advocates in the U.S. called for a national moratorium to stop doctors from removing feeding tubes from all people considered to be in a "persistent vegetative state" and who did not have an advance directive or durable power of attorney.

Not Dead Yet called for the action in response to research done at Cornell University, which suggested that people in a "minimally conscious state" may be aware of their surroundings and can hear what is going on around them -- even though they may not be able to respond. Researchers compared fMRI scans on subjects that had significant brain injuries with those done on volunteers with no brain injuries. The researchers found that while the resting brain activity for those with brain damage was almost nonexistent, their brain activity jumped up to the same level as the volunteers when researchers played audio tapes of loved ones telling familiar stories and talking about shared life experiences.
