The DC-STIMULATOR is a clinical stimulator designed to be used in clinics and medical practices. Using this device, doctors and psychologists can carry out transcranial direct current stimulation (tDCS) using weak currents up to 2 mA over 15 to 30 minutes. tDCS represents part of interventional neurophysiology; the electrical charges and densities administered during tDCS are below the threshold for releasing a stimulus and take modular effect to existing neuronal elements. Depending on duration, current intensity, current density and frequency used, the transcranial Electrical Stimulation influences cortical activity. The DC-STIMULATOR is used for tDCS for reduction of depressive symptoms. It can be applied as monotherapy or in combination with other treatments. For patients with selective serotonin reuptake inhibitor (SSRI) medication and failure to another drug, no further benefit of tDCS beyond unspecific (placebo) effects can be expected. • highest patient safety standards due to multistage monitoring of the current path, automatic termination of the stimulation as well as continuous monitoring of the electrode impedance • intuitive menu navigation via display and four buttons • individual setting and saving of the stimulation parameters • optional: study mode for double-blind active and sham stimulation
