How a Simple Blood Test Could Change Brain Injury Care, with Linda Papa, MD, MSc

Active patient involvement in their care is crucial, especially when dealing with traumatic brain injuries. While some patients may be cognitively impaired, those with a Glasgow Coma Scale (GCS) score of 15, for example, should be fully engaged in discussions about new diagnostic tools, such as the newly US Food and Drug Administration (FDA)-approved blood test for traumatic brain injury. This blood test provides valuable biomarker levels that indicate the severity of the injury.

In an interview with Linda Papa, MD, MSc, director of Academic Clinical Research at Orlando Health, explains this test represents a significant advancement in the management of concussions or mild traumatic brain injuries, which are often considered similar in treatment. In the past, 30% of these patients experience complicated recoveries despite having normal CT scans. The introduction of this blood test allows healthcare providers to identify high-risk patients early on, validate their symptoms and guide them toward appropriate follow-up care.

Previously, the absence of such tools meant that patients with normal CT scans were often sent home without much concern for potential long-term effects. However, with the new test, medical professionals can now provide a better picture of the injury's severity. This not only helps in early intervention but also ensures that patients and their families understand the seriousness of the condition, even when initial imaging results appear normal.

Moreover, the test can significantly improve communication between patients, their families and healthcare providers. It allows for more informed decision-making and ensures that patients who may face a challenging recovery receive the necessary attention and care. By catching the third of patients who are likely to struggle with recovery early, clinicians can offer more targeted treatments and support, ultimately leading to better outcomes.

The new blood test for traumatic brain injury marks an important step forward in patient care, Papa says, enabling more accurate assessments, validating symptoms and improving the overall management of brain injuries. By using this tool, providers can move beyond the limitations of traditional CT scans and provide patients with the attention and care they need to fully recover.
