Each year more than one and a half million people suffer traumatic brain injuries at least 75% of them are classified as mild T-B-I's or concussions.
Now, new research in the journal Radiology shows that even a single concussion may cause lasting structural damage to the brain.
The study began with 28 patients who had post-traumatic symptoms after an injury and 22 healthy patients chosen for comparison.
The researchers used MRI to determine regional gray matter and white matter volumes and then correlated these findings with other clinical and cognitive measurements.
The results showed that one year after injury, there was measurable volume loss or atrophy in both global and regional areas of the brain in the concussion patients.
The researchers say this study confirms that brain atrophy is not exclusive to more severe head trauma but can occur after a single concussion.
It is important for anyone who exhibits symptoms of a concussion to be evaluated by a doctor.
