The study involves 200 Veterans with chronic effects of mild traumatic brain injury (mTBI), which is a concussion, and PTSD. Half will undergo a form of non-invasive transcranial electrical stimulation called IASIS that sends low-intensity pulses to the brain, combined with an EEG (electroencephalography) to monitor brain activity. The pulses are aimed at reducing abnormally slow brain waves, as well as post-concussion and PTSD symptoms.
The rest of the Veterans are in a control group. They will not get IASIS Micro Current Neurofeedback but will be scanned multiple times to assess the test-retest reliability of the MEG measurements.
