Treating Traumatic Brain Injury With Transcranial Direct Current Stimulation
Sponsor: Johns Hopkins University
Summary
Traumatic Brain Injury (TBI) often results in a wide array of cognitive impairments, which can significantly diminish quality of life for affected individuals. While traditional rehabilitation methods typically adopt a standardized approach, it's crucial to acknowledge the significant heterogeneity within the TBI patient population. Neglecting these variations reduces the likelihood of otherwise effective treatments being considered for widespread adoption. Emerging evidence highlights the potential of transcranial direct current stimulation (tDCS) as a promising adjunctive therapy. tDCS, a noninvasive and safe neuro-rehabilitative procedure, has shown efficacy when integrated with cognitive training across various neurological disorders, such as depression, post-stroke aphasia, and neurodegenerative conditions. This study aims to investigate the effectiveness of tDCS paired with behavioral therapy, particularly cognitive training, in improving cognition and executive function in chronic TBI patients. Additionally, tDCs targets in the current study will be tailored to each individual patient, recognizing the patient's unique needs and circumstances

Interventions
Active tDCS on the DLPFC + Cognitive Intervention(s)
Combination Product: Active tDCS and cognitive training intervention. Participants will receive cognitive training paired with active tDCS for 3 weeks, followed by follow-up sessions immediately after and 2 months later, during which the patient's performance on the cognitive training exercises and executive functions will be assessed. Cognitive training exercises have been drawn from a computer-aided cognitive training program (BrainHQ). For the active tDCS, stimulation will be delivered by a battery-driven constant current stimulator. The electrical current will be administered to the left DLPFC at an intensity of 2 milliamperes (mA) (estimated current density 0.04 mA/cm2; estimated total charge 0.048 Coulombs/cm2) in a ramp-like fashion for a maximum of 20 minutes.
Sham tDCS on the DLPFC + Cognitive Intervention(s)
Combination Product: Sham tDCS and cognitive training intervention Participants will receive cognitive training paired with sham tDCS for 3 weeks, followed follow-up sessions immediately after and 2 months later, during which the patient's performance on the cognitive training exercises and executive functions will be assessed. Cognitive training exercises have been drawn from a computer-aided cognitive training program (BrainHQ). For the sham tDCS, electrodes will be placed in the same area as in the active tDCS condition, but current will be administered in a ramp-like fashion but after the ramping the intensity will drop to 0 mA. Current under the Sham condition will last for a maximum of 30 seconds.
