Trial summary

Background: The amount of blood flowing in brain areas goes up when those areas are being used for activities, such as movement or seeing. Functional magnetic resonance imaging (fMRI) is a common way of measuring blood flow in the brain. Read more about this study

About this study

Official title: Detection of Hemodynamic Changes in Traumatic Brain Injuries Population With Functional Near Infrared Spectroscopy

Background:

  • The amount of blood flowing in brain areas goes up when those areas are being used for activities, such as movement or seeing. Functional magnetic resonance imaging (fMRI) is a common way of measuring blood flow in the brain. Near infrared spectroscopy (NIRS) can also be used to study blood flow in the brain. However, NIRS has not been used as often as fMRI. Researchers want to compare fMRI and NIRS to see whether they give similar results. These studies will be used to look at people who have had a traumatic brain injury.

Objectives:

  • To test how well NIRS measure changes in blood flow in the brain after a traumatic brain injury.

Eligibility:

  • Individuals between 18 and 60 years of age who have had a traumatic brain injury.
  • Healthy volunteers at least 18 years of age.

Design:

  • Participants will be screened with a physical exam and medical history. Researchers may ask to see brain images during from previous MRI scans.
  • Participants will have a NIRS scan of the brain. They will be asked to do certain tasks while inside the scanner. These tasks will involve responding to images that appear on a screen.
  • Treatment will not be provided as part of this study.
Read the detailed description

The goal of this study is to be able to assess frontal lobe function in a rapid, objective, and standardized way, without the need for expertise in cognitive test administration. Such methods would be particularly helpful in mild traumatic brain injury, where objective measures are needed, and would greatly expand the capacity to make such assessments in standard clinical practice.

Our goal is to recruit 100 subjects total in two groups of age, gender, and education matched subjects, as follows: TBI (n = 50) and non-TBI (n = 50).

The subject will be asked to perform 2 computer-based cognitive tests while the fNIRS device is in place. The fNIRS sensor pads will record changes in blood oxy/deoxy hemoglobin concentrations in the underlying cortex. Data will be stored for post processing analysis.

The main outcome measures will be: 1) a correlation of the fNIRS results between the TBI and non-TBI groups; 2) a correlation of the fNIRS results with the severity of the TBI within the TBI group. Finally, we plan to compare individual measurement from TBI patients with the healthy group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The main outcome measures will be to identify if the brain flow hemodynamic between the healthy and the TBI group is affected by trauma.

Secondary outcomes (1)
  1. The secondary outcome of the two parametric paradigms will investigate if the degree of disruption correlates with measures of the severity of injury (GC scale). Finally, we will compare individual measurement form TBI patient with the health...

Questions about this trial

What is this clinical trial studying?

An observational study of Cognition Disorder and Functional Brain Imaging, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The main outcome measures will be to identify if the brain flow hemodynamic between the healthy and the TBI group is affected by trauma.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01668758, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2017.
