简要总结
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.
详细描述
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.

入选标准
- •OIF/OEF Veteran;
- •Neuropsych diagnosis of MTBI
排除标准
- •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.
结局指标
主要结局
