This study analyzes changes in magnetic susceptibility in brain tissue after repeated mild traumatic brain injury, indicating significant neurobiochemical alterations.
Key Points
Repeated mTBI causes greater neurological deficits than single mTBI, lasting for 8 weeks.
Changes in magnetic susceptibility were more pronounced in the chronic stages after repeated mTBI.
Quantitative susceptibility mapping successfully detects neurobiochemical changes related to mTBI.
Fluorescence staining highlighted glial proliferation and Tau protein deposition following mTBI.
