About

Background:

- The Center for Neuroscience and Regenerative Medicine is working to improve physicians' understanding of brain injury. More information is needed on traumatic brain injury (TBI), especially how well a person recovers from TBI and how the brain changes over time in people with TBI. To conduct this research, the center is sponsoring a number of research studies on TBI and is interested in evaluating individuals with TBI or post-concussive syndrome to determine if they might be eligible for future studies.

Objectives:

- To develop a pool of individuals with traumatic brain injury and post-concussive syndrome for future research studies.

Eligibility:

- Individuals at least 18 years of age who have symptoms of or have been diagnosed with traumatic brain injury or post-concussive syndrome and are willing to participate in future studies.

Design:

• Participants will be screened with an initial telephone interview, and will be asked to come to the National Institutes of Health for an in-person screening visit.
• At the screening visit, participants will provide a medical history, have a physical examination and complete a study questionnaire on their TBI and its symptoms, including how the injury occurred, when it occurred, and any previous brain-related injuries.
• Subjects may also return for a second visit at the NIH CC if eligible.
• Each visit may involve blood samples, an MRI scan, and a series of tests to evaluate brain function.
• Participants will also provide contact information to enable researchers to contact them for future studies.

Full description

Objective

This screening and registry protocol is designed to facilitate subject recruitment for the Center for Neuroscience and Regenerative Medicine (CNRM) sponsored clinical research studies on traumatic brain injury (TBI) at the National Institutes of Health (NIH) and participating CNRM sites. This protocol will serve as a first step for evaluating subjects for possible inclusion in CNRM sponsored natural history, observational, or interventional protocols. Other approved CNRM protocols may continue to recruit subjects directly into their respective studies, and may refer subjects to this study.

The objective of this protocol is to develop a subject recruitment database that will house preliminary data on research subjects who are interested in and potentially eligible for current and future CNRM sponsored protocols. The effectiveness of the recruitment methods utilized in this protocol will be evaluated to determine the most successful outreach approaches and recruitment tools for the enrollment of TBI or post concussive study subjects.

Study Population

This protocol will enroll 2500 male and female adult subjects with signs/symptoms or diagnosis of TBI or post-concussive syndrome, from participating sites, other CNRM sponsored protocols and within the community using various methods of outreach and advertisement.

Design

This study involves an initial study visit conducted in one of two ways: at the NIH Clinical Center,or at the participating site. Subjects enrolled acutely and/or at a participating site may also be provided the option to complete an additional visit at the NIH CC after their initial visit. Based on the information obtained during the initial study visit, the subject will be referred to appropriate CNRM protocols for further protocol-specific screening prior to enrollment, or informed that s/he is not eligible for any other actively enrolling CNRM studies at this time. Study procedures may include: physical exam, medical history, nursing evaluation, questionnaires completed by interview, blood and urine sample collection, and magnetic resonance imaging (MRI).

Follow-up visits will be conducted by telephone at regular intervals for a year, and then ad hoc at potential referral eligibility to update contact information and collect outcome data. No treatment is offered under this protocol.

Outcome Measures

The outcome measures include accrual of subjects, retention of enrolled subjects and loss to follow-up, and referral number and rate of enrolled subjects to other CNRM studies. In addition, we will evaluate the frequency and certainty of injury classification (possible, probable, or definite TBI).

Enrollment: 1,328 patients
