Targeting Brain Physiology to Treat Neuropsychiatric Symptoms of Dementia Using TMS-EEG and tDCS

tDCS is a non-invasive brain stimulation modality that does not require general anesthesia or surgical implantation of a device. tDCS utilizes low intensity electrical current either to increase cortical excitability with an anodal electrode or to suppress cortical excitability with a cathodal electrode. It uses 3 AAA batteries to deliver direct current via rubber electrodes enclosed in saline soaked sponges.
