Mild brain injury in children may cause structural changes to the brain
A brain injury in a child, even what physicians call a “mild traumatic brain injury”, may have lifetime affects according to according to a study published in the December 12 issue of The Journal of Neuroscience.
The researchers studied the brains of children who sustained a mild traumatic brain injury or a concussion using an advanced MRI imaging technique known as diffusion tensor imaging (DTI). Using this sophisticated imaging technology, the study found that even following a mild tbi, children exhibit structural changes to the white matter of the brain which can lead to permanent disability. The white matter nerve tracks in the brain carry nerve signals from one region of the brain to another.
Importantly, the study found these changes remain within the brain even though the child may seem symptom free of the typical post- concussion symptoms of headache, nausea, dizziness, sensitivity to light or sound and ringing in the ears.
