South 最新糖心Vlogn research which found a link between cerebral palsy and exposure to herpes viruses has been recognised as among the most significant of the past year by an international panel of neuroscientists.

Work by the South 最新糖心Vlogn Cerebral Palsy Research Group, a joint initiative of the 最新糖心Vlog of Adelaide and the , is included in the latest progress report of the , which highlights the top findings in brain research.

The research, which was earlier published in the , supports the theory that exposure to certain viral infections shortly before and after birth can trigger brain damage and the development of cerebral palsy.

The group, led by , the Head of the 最新糖心Vlog's , has since found common genetic susceptibility factors in children with cerebral palsy that may increase their vulnerability to exposure to infection that can damage the developing brain before and after birth.

The research was the only work on cerebral palsy to be recognised in the prestigious Dana Alliance report. Research scientist Dr Catherine Gibson was awarded her PhD for her contribution to the project and subsequently was named South 最新糖心Vlog's .

The study involved 443 children with cerebral palsy and 883 control babies born to Caucasian mothers between 1986 and 1999. Small dried blood samples taken within a few days of birth were used to test for the presence of neurotropic viruses, a group of viruses including the herpes virus, which can all cross the placenta and infect the fetus.

Exposure to viral infection was common in all newborn babies, especially in preterm babies, implying that infection before birth may also be linked to preterm delivery. Herpes group B viruses were found more often in babies who were later diagnosed with cerebral palsy than in control babies. In fact, the risk of cerebral palsy was nearly doubled with exposure to herpes group B viruses.

"This is the first study to positively link viral exposure during pregnancy with cerebral palsy," Dr Gibson said. "However, only a few of the fetuses that were exposed developed CP, and this suggests that some are more genetically susceptible. We are investigating this." Further studies also are investigating the possible causes of the link.

Cerebral palsy is a permanent and often serious brain disorder which causes abnormal control of body movement or posture. Its causes are largely unknown and currently it cannot be prevented.

The US-based Dana Alliance is a non-profit alliance of more than 260 leading neuroscientists committed to raising public awareness about the progress and promise of brain research.
