Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 65 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Mild Traumatic Brain Injury Normal health controls

Who may be able to join

  • Mild to moderate brain injury patients referred to the UCI Brain Imaging Center.
  • Mild brain injury patients will be defined as having a Glascow Coma Scale (GCS) scale of 13-15.
  • Moderate brain injury brain injury patients will be defined as having a Glascow Coma Scale (GCS) scale of 9-12 .
  • Normal healthy control subjects (20)

Who cannot join

  • Pre-accident neuropathology, psychopathology, or secondary neuropathological complications, or chemical abuse
  • Patients who required intracranial surgical intervention
  • Children, pregnant women, or institutionalized individuals unable to freely give consent
  • Patients with implanted surgical clips (hemostatic clips) or other ferromagnetic material
  • Patients engaged in occupations or activities which may cause accidental lodging of ferromagnetic materials, or who may have imbedded metal fragments from military activities
  • Patients with permanent (tattoo) eye-liner or with facial make-up (severe eye irritation has been reported)
Show all 10Show fewer
  • Patients with metallic implants, because they may cause artifacts in diagnostic images due to magnetic field distortion
  • Patients with implanted prosthetic heart valves
  • Patients with pacemakers, neuro-stimulation devices
  • Subjects who have severe claustrophobia.

About this study

The purpose of this study will be to assess the attentional ability of patients with mild to moderate traumatic brain injury (TBI) using the functional Magnetic Resonance Imaging (fMRI) technique. Methodology for specific aim 1: sagittal pilot scan, 3-D anatomical MRI, Whole brain echo-planar imaging (EPI), and functional MRI techniques with traumatic brain injured subjects doing a Continuous Performance Test (CPT) attention task and compare the pattern of activation with those of normal controls to see if there is a failure to activate frontal lobes in the traumatic brain injured subjects.

Questions about this trial

What is this clinical trial studying?

An observational study of Mild Traumatic Brain Injury, run by University of California, Irvine at 1 site in United States.

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 4 inclusion and 10 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 25 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

fMRI scans (time frame: three to four years post injury). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Jan 2021; AzTrials last refreshed its copy on 1 Nov 2026.
