• severe traumatic brain injury (based on the Ohio State TBI Identification; Method);
• brain tumor;
• implanted brain medical devices, including, deep brain stimulators (DBS);
• implanted pacemakers;
• vascular clips or other electrically sensitive support systems in the brain;
• damaged skin at the sites of stimulation (the device should only be used on healthy, intact skin, as wounds may alter resistance to current);
• pregnant women;
• anti-convulsants;
