Patient Recruitment

Have you recently experienced a head injury?

Researchers at the National Institutes of Health (NIH) are conducting a research study for people who have experienced a mild to moderate head injury within the last 30 days. The purpose of the research is to help determine why some people go on to develop additional health problems following a head injury while others do not.

A mild to moderate head injury can be caused by a sports-related injury, car or bicycle accident, fall, violence, injury when on military service, or other kind of accident. A mild to moderate head injury may or may not cause loss of consciousness. After the head injury people may experience symptoms such as headaches, sleep disturbance, irritability, noise or light sensitivity, memory problems and difficulty focusing on tasks. Some individuals may also go on to develop other health problems such as post-traumatic stress disorder (PTSD), depression, and post-concussive syndrome.

You may be eligible if you:

  1. Are 18 to 65 years old
  2. Had a mild or moderate head injury (including concussion and traumatic brain injury) within the last 30 days
  3. Are able to give your own consent

You may NOT be eligible if you:

  1. Have been diagnosed with schizophrenia or bipolar disorder
  2. Have or have had PTSD
  3. Are currently depressed

About the study:

  • Outpatient screening visit to determine if you are eligible
  • 4 follow-up outpatient study visits over one year
    • Study visits include questionnaires, blood work, saliva collection, and interviews with a behavioral health nurse
    • Study visits may also include an optional MRI brain scan and an optional test to see how you respond to stress
    • The length of each study visit may vary from approximately 5 to 7 hours depending on participation in optional tests

All study related tests and visits are at no cost. Compensation for participation is provided. Local travel may be arranged or reimbursed by the study team.

The study takes place at the NIH Clinical Center, America's Research Hospital in Bethesda, MD. We are on the Metro red line (Medical Center stop).
