Trial summary

Approximately 1.1 million people a year suffer a mild traumatic brain injury (MTBI), or concussion, in the United States. Although most MTBI patients fully recover, as many as 28% have physical, cognitive, and/or emotional symptoms up to 6 months post-injury. Read more about this study

About this study

Official title: An fMRI Study of Selective Attention, Working Memory, and Effort After Mild Traumatic Brain Injury

Approximately 1.1 million people a year suffer a mild traumatic brain injury (MTBI), or concussion, in the United States. Although most MTBI patients fully recover, as many as 28% have physical, cognitive, and/or emotional symptoms up to 6 months post-injury. When symptoms persist past three months, it is known as post-concussion syndrome (PCS). The cause of PCS is unknown, as structural neuroimaging and neuropsychological (NP) testing results are often normal. However, recent functional magnetic resonance imaging (fMRI) research in concussed adults showed differences in brain activity compared to controls on working memory tasks, despite normal structural MRI and neuropsychological findings. We propose improving this research by assessing brain activation patterns during simple versus complex attention and working memory tasks in 10 concussed adults via fMRI. This will be the first study to examine brain activation patterns associated with the degree of effort applied to testing, a factor known to confound interpretation of NP test performance. Validated computerized measures of selective attention (Modified Stroop Interference Task), working memory (n-back), and effort (Green's Medical Symptom Validity Test; MSVT) will be used. Ten paid controls will be used for comparative purposes. We hypothesize that concussed patients will show less brain activation than controls on complex versus simple working memory tasks and that activation patterns in concussed patients will generally be lower in those with suboptimal effort. We will also characterize self-reported emotional and physical symptoms in the PCS patients, which has not been done in prior fMRI research with this population.

Questions about this trial

What is this clinical trial studying?

An observational study of Post Concussive Syndrome, run by State University of New York - Upstate Medical University 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: stopped early, as of the sponsor's last update on 3 May 2016. 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 stopped early (reason given: Difficulties with recruitment and MRI scanner became unavailable.). Results are not available in the source record.

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?

BOLD Response (time frame: Patients will undergo fMRI at least one month after 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 3 May 2016.
