About

The study investigates whether the use of eye movement recordings can provide a reliable diagnostic of previously undiagnosed mild traumatic brain injury (blast and impact) in Operations Enduring Freedom or Iraqi Freedom (OIF/OEF) veterans.

Full description

Eye movements are recorded for Operations Enduring Freedom or Iraqi Freedom (OIF/OEF) veterans with mild traumatic brain injury (mTBI) and compared to the eye movements of those without mTBI. By analyzing and characterizing the differences between the two groups, a diagnostic measure of mTBI through the use of eye movements can be developed.

Enrollment

26 patients

Sex

All

Ages

18 to 55 years old

Volunteers

Accepts Healthy Volunteers

Inclusion criteria

  • OIF/OEF Veteran;
  • Neuropsych diagnosis of MTBI

Exclusion criteria

  • chronically abusing alcohol or illicit drugs.
  • uncorrected vision prevents subject from effectively viewing the stimuli, unless they can wear contact lenses during the recording session.
  • inability to make normal eye movements (i.e.: saccades, smooth pursuit) required by study paradigms. Note: Deficit can be caused by taking medications that can potentially affect eye movements or any neurological condition that can interfere with making normal eye movement.
  • psychological or psychiatric conditions that preclude sustained concentration or ability to perform the tasks.
