What the Study Involves
• Questionnaires and surveys about your health   

• Tests of cognitive function, balance, and eye-muscle coordination
• Imaging of bone and muscle

What the Study Involves: 

  • 2-3 visits; questionnaires and cognitive testing

  • Blood draw, saliva sample, and a brain scan using MRI (magnetic resonance imaging)

  • Participants will receive monetary compensation and a Fitbit device.

Title:   Comparing the Effectiveness of Telehealth to In-Person Delivery of Combined Metacognitive and Attention Training in Veterans with Mild Traumatic Brain Injury/PTSD

Purpose Having both mild traumatic brain injury (mTBI) and post-traumatic stress disorder (PTSD) can decrease organizing and planning skills, which can have a substantial impact on ability to take care of many aspects of life from paying bills to remembering birthdays. This study will compare in-person and telehealth delivery of the same therapeutic interventions to see if either method is more effective.
