Mapping the Connectome Following Traumatic Brain Injury

Area of Science:

• Neuroscience
• Medical Imaging

Background:

• Traumatic brain injury (TBI) lacks reliable biomarkers for detection, severity grading, and recovery monitoring.
• Current diagnostic and prognostic tools are insufficient for personalized patient management.

Purpose of the Study:

• To explore the potential of advanced brain mapping techniques in addressing the biomarker gap in TBI.
• To highlight how molecular and anatomical mapping can define TBI signatures and track recovery trajectories.

Main Methods:

• Utilized magnetic resonance techniques including diffusion weighted imaging, diffusion tensor imaging, susceptibility weighted imaging, magnetic resonance spectroscopy, and functional magnetic resonance imaging.
• Incorporated positron emission tomographic methods and molecular neuroimaging.

Main Results:

• Brain mapping reveals TBI as a disorder of large-scale neural connectivity.
• Mapping molecular, anatomical, and functional changes provides unique endophenotypes for TBI.

Conclusions:

• Advanced brain mapping offers a transformative approach to classifying and treating TBI patients.
• These methods have the potential to improve individual-level TBI diagnosis, prognosis, and treatment strategies.
