Early warning test for Parkinson's receives national recognition
The research of Dr Kay Double, an NHMRC Senior Research Fellow at the Prince
of Wales Medical Research Institute, has received the nation's highest
commendation through her inclusion in the NHMRC's 2006 "10 of the Best"
booklet.
This national publication will be launched by The Minister for Health and
Ageing, Tony Abbott at 10am, Friday 1 September in the Scientia Gallery,
University of New South Wales.
Dr Double's research into Parkinson's disease looks at the function of
neuromelanin, a pigment unique to human brains. In the brain cells of a
person with Parkinson's disease, this pigment disappears. Based on her
findings, Dr Double and her team have developed a new blood test which will
provide early detection for the loss of neuromelanin and this may predict the
onset of Parkinson's.
Dr Double's work investigated the vulnerability of the pigment in a
Parkinson's disease brain, how it occurs in a healthy brain, why these
changes occurred and the consequences of changes for the survival of the
brain cells.
"We found that the pigment in the healthy brain protects the cells from free
radical-damaging molecules and other toxins," she said, "but in the
Parkinson's diseased brain, the pigment is changed so that instead of
protecting the cells, it becomes toxic itself.
"Our research indicates that increased amounts of iron bound to the pigment
cause the cells to be damaged and die."
"This research is significant it has allowed us to design a new blood test for
the onset of Parkinson's disease. It has also highlighted the potential to
develop new treatments to slow down, or even stop altogether, brain cell
death," concluded Dr Double.
The blood test, currently being commercialised, will not only provide early
detection but also correct diagnosis of Parkinson's disease. At the moment,
Parkinson's disease can be diagnosed only after signs such as slowness,
stiffness and tremor appear.
The Institute's Executive Director, Prof Peter Schofield said," Kay's
outstanding research, conducted at the Institute over the past five years,
validates our mission to conduct world-class medical research to cure human
disease, improve quality of life, and thus create a legacy for the future.
This recognition by the NHMRC is a direct reflection of her exceptional
ability in the research arena."
Dr Double has been awarded a NHMRC Senior Research Fellowship to continue her
research into the causes, diagnosis and treatments of Parkinson's disease.

(Dr Double has been invited to present her findings at the European Federation
of Neurologists in Glasgow next week and leaves Sydney at 2.00pm Saturday
morning 2 September - any interviews will need to be prior to this.)
