To learn more about what happens in the brain when someone has thought about or attempted suicide, researchers study a comparison group of people without suicidal thoughts. 

You may be able to participate if you are:

  • Ages 18 to 70 years 
  • Have no previous or current suicidal thoughts

Study participation includes these procedures:

  • Blood tests
  • Medical and psychological evaluations
  • Brain scans
  • Computer tasks
  • Sleep studies
  • Psychiatric interviews

This inpatient or outpatient study is conducted over 3 to 9 days at the NIH Clinical Center in Bethesda, MD. There is no cost to participate. Compensation is provided. We enroll eligible participants locally and from around the country. Travel arrangements are provided, and costs are covered by NIMH (arrangements vary by distance). Pregnant women and individuals with serious medical conditions are not eligible.
