New Blood Test Can Be Used to Check for Brain Injury, Severity of DamageEvery year, millions of Americans suffer from traumatic brain injuries (TBI) after being injured in car accidents, sports games, falls, assaults, and combat. A person affected by a TBI can suffer from symptoms ranging from headaches and dizziness to seizures, comas, paralysis, and death.

Previously, the only way to diagnose a TBI was to perform a CT scan which can check for bleeding in the brain. However, this test can only confirm the presence of blood in the brain, and cannot tell doctors about the injury affected the brain cells themselves. This meant that doctors would need to make educated guesses towards the nature and severity of the injury based on the symptoms.

Now, a new blood test may change the way TBIs are diagnosed and treated. According to a study published in the Journal of Neurotrauma, researchers have identified a protein in the blood called brain-derived neurotrophic factor (BDNF), which can help doctors detect a TBI and gauge its severity. This test may help doctors identify which patients would benefit from specialized treatments, extra therapy, or experimental options.

Researchers found that healthy people had an average amount of 60 nanograms per milliliter of the BDNF protein in their blood. Patients with brain injuries averaged about 20 nanograms, and patients the most severe brain injuries recorded levels as low as 4 nanograms of BDNF per milliliter in their blood. These levels were recorded after testing blood taken within 24 hours of the injury.

After six months, patients with higher levels of BDNF had almost completely recovered from their injuries. Those with low levels of BDNF still faced multiple problems stemming from their injuries during follow up visits with the researchers.

Many are hopeful that this blood test can be used to identify patients with brain injuries immediately after their injury. Before the development of this test, patients who came to the emergency room after a blow to the head were often sent home if the CT scan showed no bleeding. However, these patients, who may have had low-grade TBIs, would continue to show symptoms like difficulty concentrating or problems with their memory.

Now, these patients can be referred for treatment and advised on what to expect while recovering from a brain injury. Doctors may be able to quickly identify which patients would need to take time off of work or school to recover, which patients should follow up with a neurologist for treatment, and which patients would benefit from long-term physical therapy.

The effects of a TBI can linger for years. Patients who are facing years of rehabilitation or therapy need to understand the extent of their injuries so that they can plan for their future. For those who were injured by another person’s negligence or wrongdoing, the BDNF blood test may provide strong evidence in a personal injury lawsuit. If the test shows the severity of the TBI, this information can be used to determine how much money should be awarded to the patient for future medical care and rehabilitative expenses.

A traumatic brain injury can be devastating for the affected person, and his or her family and friends. When a TBI is caused by the negligent act of another person, the victim may be able to file a lawsuit seeking compensation for medical bills, physical therapy, pain and suffering, and any other damages which are appropriate.
