No results posted yet for this study

Summary

We plan to study patient who faint in response to the sight of blood and compare them to healthy subjects who do not. We are going to use a special type of MRI scan (functional MRI) to determine if there are differences in brain activation in response to seeing bloody or gory pictures that occur before the fainting occurs.

Conditions

  • Syncope
  • Blood Injury Phobia
  • Autonomic Dysfunction

Interventions

fMRI Scan

Subjects will undergo a functional MRI scan of the head lasting \~45 minutes. They will be repeatedly shown video clips of blood, other disgusting things, or are neutral.
