Multimodal Approach to Testing the Acute Effects of Mild Traumatic Brain Injury (mTBI)

November 6, 2017 updated by: Michael G Harrington, Huntington Medical Research Institutes
The objective of the study is to determine the relative roles for various testing modalities in the diagnosis and prognosis of mild traumatic brain injury.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Subjects will undergo functional brain testing (magnetoencephalography, electroencephalography), anatomical brain imaging (diffusion tensor imaging, susceptibility-weighted imaging), neuropsychological testing (memory, language, processing speed), sleep patterns using actigraphy, and blood testing of candidate biomarkers. Testing will be done at 3 time points post-injury: 1 day, 14 days, and 30 days post-injury. Analysis of these tests collectively will be used to develop diagnostic tools for acute mTBI.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Study participants (control, mTBI) will be referred by the Huntington Hospital Emergency Department staff. ED staff will determine the eligibility criteria. If consent is achieved, testing will occur at pre-determined times: 1 day, 14 days, and 30 days post-injury.

Description

Inclusion Criteria:

1. Civilian (non-military) presenting to HMH ED.

Exclusion Criteria:

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

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in objective measures of brain function (MEG/EEG, blood biomarkers)
Time Frame: 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.
Day 1, day 14, and day 30 post-injury

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in anatomical measures of brain function (DTI, SWI)
Time Frame: 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).
Day 1, day 14, and day 30 post-injury

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
