Australian researchers are moving the needle even further in diagnosing cerebral palsy early. Using MRI scans, they have connected certain brain damage patterns to genetic and other causes, making it easier to identify cerebral palsy or the need for genetic testing. The research should help children get earlier, more effective treatment and help explore the many causes of CP.
MRIs Reveal Brain Injury Patterns and Genetic Factors in Children with Cerebral Palsy
Researchers from the University of Adelaide and an international team analyzed the MRI scans of the brains of over 300 Australian children already diagnosed with cerebral palsy. They recently published the results in the journal eBioMedicine.
Only 8% of the scans were normal, revealing no obvious brain injuries. The rest of the scans showed various types and patterns of brain injury. Half of the children had damage to white matter in the brain, while 21% showed injuries in gray matter. About 10% of children showed abnormal brain development, and another 10% had less common injuries associated with cerebral palsy. These included infection, tumors, and genetics.
Cerebral palsy is typically caused by abnormal brain development or brain injury acquired during pregnancy, childbirth, or shortly after delivery. The researchers in this study concluded that the small percentage of children with no signs of injury likely had genetic causes of CP.
The Importance of Early Diagnosis and Treatment for CP
Cerebral palsy is a complex condition that varies in severity and complications. Children have the best outcomes when they receive an early diagnosis because this allows for early interventions that more effectively impact the developing brain.
The researchers in this study hope that the use of MRI will reveal distinctive patterns that make CP easier to diagnose. They also hope it will help determine which children could benefit from genetic testing to make a better diagnosis.
MRIs Hint at Complex Causes of Cerebral Palsy
The results of the study found that genetic factors linked to CP were not limited to the children with no MRI signs of brain injury. The researchers found genetic factors for CP in some of the children with each type of brain injury pattern. About one quarter of all the children with CP had genetic factors.
This means that there is rarely a single, simple cause of cerebral palsy. Genetics, environmental factors, and combinations of the two can all cause CP. By combining MRI scans with genetic testing, the researchers hope to untangle some of the complexities and tailor treatment plans to individuals.
For children and families, this work should lead to earlier, more accurate diagnoses and better, more effective treatments.
