Traumatic microbleeds may predict worse outcomes following head injury


Using advanced imaging techniques, researchers have revealed new information regarding traumatic microbleeds – these appear as small, dark lesions on MRI scans after a head injury, however, they are typically too small to be detected on CT scans.  

The findings, which have been published in Brain, suggest that traumatic microbleeds may be a form of injury in relation to blood vessels in the brain and may predict worse outcomes.  

“Traumatic microbleeds may represent injury to blood vessels that occur following even minor head injury,” commented senior author, Lawrence Latour (Center for Neuroscience and Regenerative Medicine, MD, USA). “While we know that damage to brain cells can be devastating, the exact impact of this vascular injury following head trauma is uncertain and requires further study.”
