When a brain injury occurs, it is crucial to go to a hospital or diagnostic imaging clinic to have a CT Scan or MRI test completed right away to assess what has happened.
A recent study found that , however, that CT scans can miss minor bleeds on the brain. Individuals with mild traumatic brain injuries may have normal CT Scans. It may take more sophisticated scans to see abnormalities. MRIs are of course, more expensive.
The study tracked patients with mild TBI for 3 months. Researchers found that over a quarter of patients with normal CT Scans on the day of injury had positive findings on their MRIs when tested a week later. Further testing showed that full recovery had not taken place after 3 months.
An MRI study is a more comprehensive study and is better able to show a comprehensive picture of damage.
This is why it is so important for patients to tell their doctors exactly how they are feeling and if they are experiencing any problems after a head injury.
The study showed that MRIs are able to show focal lesions, which are areas of microscopic bleeding in the brain.Researchers can use the presence of focal lesions to predict which patients are more likely to have ongoing neurological problems.
MRIs are better indicators of the course of injury and recovery.
A brain injury can cause long term damage to the brain. A traumatic brain injury can lead to inflammation and slow regeneration of brain cells. A study from the University of South Florida, found that even at the most chronic stage of injury, therapeutic intervention can help with the regeneration of brain cells. The study examined brain injuries to different areas of the brain and found that TBIs caused a second wave of cell death that impairs cell proliferation and impedes that brain’s ability to regenerate cells.
The study’s researchers found that microglia cells at the injury site and distant sites were activated around 8 weeks after injury. The researchers feel that therapeutic intervention may help prevent some long term damage to the brain.
According to the Centre for Disease Control and Prevention (CDC), 1.7 people sustain a traumatic brain injury per year and of that number, 75% are concussions or some other form of mild TBI.
