Neural Injury in Adolescents With Concussion

July 23, 2018 updated by: Children's Hospital of Philadelphia
This study utilizes multimodal brain imaging to obtain quantitative biomarkers of brain injury and to improve understanding of the biological basis of brain pathology in adolescents with concussion. Adolescents with a concussion will undergo neuroimaging and neuropsychology assessments acutely and four months after injury.

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Concussion is a highly prevalent condition in adolescence, but it remains a clinical diagnosis that largely relies on subjective patient report with no reliable objective biomarkers for diagnosis. Traditional clinical brain imaging has not been found useful for concussion as the pathology is generally not visible on conventional acute MRI or CT. The proposed study addresses this gap in concussion diagnosis and management by examining the sensitivity of magnetoencephalography (MEG) for identifying areas of brain injury through detection of abnormal neural activity (slowing) in adolescents with concussion compared to healthy controls. Adolescents with a concussion will complete neuroimaging (MEG and MRI) and neuropsychology assessments at two time points within ten days and then again 4 months post-injury. Healthy controls will complete neuroimaging and neuropsychology assessments at a single time point.

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

12 years to 17 years (CHILD)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adolescents with a recent concussion will be recruited from outpatient clinics in orthopedics and trauma surgery. Healthy controls will be obtained via volunteers and previous brain imaging research studies.

Description

Inclusion Criteria:

  • Diagnosis of concussion and within 2 weeks of injury (case subjects)
  • No history of diagnosed concussion (control subjects)

Exclusion Criteria:

  • Head injury within 1 year of recent concussion (case subjects)
  • History of neurologic, psychiatric, developmental or learning disorders (all subjects)

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.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Adolescents With Concussion
Adolescents with a concussion (n=120) will undergo neuroimaging (MEG and MRI) and neuropsychology assessments at two time points in the acute and chronic periods after injury, respectively. Brain imaging injury measures will be compared to a control normative database we will create. These brain measures will also be associated with cognitive and clinical outcomes.
Device: MEG
MEG is a non-invasive functional imaging technique that can measure slow-wave neural activity.
Device: MRI
MRI is a non-invasive imaging modality that provides measures of brain structure.
Behavioral: Neuropsychology assessment
A battery of tests will be administered by a neuropsychologist to evaluate the cognitive function of adolescents with concussion compared to healthy controls.
Adolescents Without Concussion
Age- and gender-matched healthy controls (n=160) will be recruited to establish a normative database of whole-brain slow-wave maps from MEG resting-state data as well as white-matter diffusion measures from MRI.

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
Difference in MEG Whole-Brain Slow-Wave Sensitivity between Controls and Concussion Patients
Time Frame: Up to 2 months
Whole-brain, resting-state slow-wave maps of whole brain activity will be obtained from the MEG imaging in both adolescents with a concussion and healthy controls. Control images will be analyzed to determine a whole brain z-score value that includes typically developing controls below the 95th percentile, the z-score threshold for this group). Z-score images for the adolescents with concussion will be obtained and the number of adolescents with concussion above this z-score threshold will be determined, and compared to the healthy controls. The sensitivity and specificity of this method determined.
Up to 2 months

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
Difference in MRI White-Matter Diffusion Measures between Controls and Concussion Patients
Time Frame: Up to 2 months
MRI diffusion data will be collected to examine associations between abnormal brain slowing and white matter damage in the adolescents with a concussion versus controls. Regions showing abnormal white matter diffusion will be comparing to normative control diffusion data.
Up to 2 months
