Beskrivelse
Inclusion Criteria:
1. Civilian (non-military) presenting to HMH ED.
Exclusion Criteria:
- Prior history of diagnosed TBI.
- Other significant non-head injury/trauma or open wound.
- Other significant medical co-morbidities, such as heart disease or cancer.
- Self-reported current use or substances contributing to ED visit (e.g. illicit drugs, medications, alcohol abuse).
- Currently diagnosed psychological condition (e.g. depression, PTSD).
- Medications for psychological or neurological disorder.
- Any implanted metal, such as medical device or braces on teeth.
- Injury to the back or other injury that will make it difficult for the participant to tolerate tests.
- Injury to dominant arm that would cause difficulty using computer or responding to stimuli during functional imaging.
- Pregnancy.

Mild traumatic brain injury (mTBI)
Patients admitted to Huntington Memorial Hospital (HMH), Pasadena CA, Emergency Department (ED) diagnosed with mTBI by history (alteration of consciousness, post-traumatic amnesia, loss of consciousness) and normal brain computed tomography (CT).

Control
Patients admitted to HMH ED for minor extremity trauma (sprains) and no evidence of mTBI

Change in objective measures of brain function (MEG/EEG, blood biomarkers)
Tidsramme: Day 1, day 14, and day 30 post-injury
|
For MEG/EEG, resting state analyses of brain function will be conducted to include frequency band analyses localizing, for example, delta slow wave activity, and establishing functional connectivity scores at three time points post injury (day 1, day 14, day 30).
For blood biomarkers, serum levels in approximately ten biomarkers will be measured to determine amount in each and if changes occur at three time points post-injury.

Change in anatomical measures of brain function (DTI, SWI)
Tidsramme: Day 1, day 14, and day 30 post-injury
|
Diffusion Tensor-derived measures will be calculated for control and mTBI participants to determine if changes occur at three time points post-injury (day 1, day 14, day 30).
