Remotely Administered tDCS to Improve Cognitive Function in Veterans With mTBI and PTSD
VA Office of Research and Development
Summary
Traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD) are common combat-related conditions that can result in impairments in cognition, including memory, attention and multi-tasking. There are few effective interventions to improve cognition in Veterans with cognitive impairment due to these conditions. Non-invasive brain stimulation techniques, like transcranial direct current stimulation (tDCS), can be used to stimulate activity in areas of the brain to optimize recovery and rehabilitation. In this study, the investigators are conducting a randomized controlled trial of tDCS to improve cognitive function in Veterans with cognitive impairment due to co-morbid TBI and PTSD. TDCS is remotely administered and paired with cognitive training.
Description
This study is a double blinded randomized controlled trial of transcranial direct current stimulation (tDCS) to improve cognitive function in Veterans with cognitive impairment due to co-morbid traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD). Eligible Veterans who choose to enroll will be randomized to active or sham stimulation with tDCS. They will undergo 10 weekdays of stimulation (active or sham) paired with cognitive training with the mobile application BrainHQ that will be conducted remotely. The Veteran and a friend/family/caregiver will be trained to perform tDCS…

Interventions
- DeviceTranscranial direct current stimulation (tDCS)
Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation. Participants will be randomized to active tDCS or sham tDCS for 20 minutes per day for 10 consecutive weekdays.
- OtherCognitive training
Participants in both arms will undergo cognitive training while tDCS (Active or Sham) is being administered. Cognitive exercises will be completed through the mobile application BrainHQ.
