• What is tDCS?
• tDCS stands for transcranial direct current stimulation. Essentially, tDCS can be thought of as brain training. Researchers have done numerous studies testing the effects of this technology on different conditions such as depression, pain and accelerated learning in addition to many others. tDCS is a non-invasive procedure in which a device sends a small Direct Current (DC) across the scalp to modulate brain function. Conventional tDCS devices will consist of a positive anode and negative cathode. When the low level current enters through the anode, the stimulation causes an excitation in neuronal activity. Conversely, when the current exits through the cathode, the stimulation causes a reduction in neuronal activity. Knowing this, anodal and cathodal stimulation, can be used in various applications to alter the neural activity of the brain. Since anodal stimulation causes an excitation in neuronal activity, it can be used to potentially enhance the area of the brain being targeted. Alternatively, as cathodal stimulation causes an inhibition of neuronal activity, it can be used to potentially decrease activity in the brain resulting from the hyper-activity associated with certain psychological disorders.

• Which device should I buy?
• At Caputron we have the largest collection of tDCS devices. One of the questions we get asked the most is what tDCS device should I buy. To help make this decision easier for you, we have put together a Device Comparison Table outlining the features found in the various tDCS devices as well as compiled a list of the Best Selling tDCS Devices.
• Do I need a prescription for tDCS or CES?
• As tDCS is an investigational technology with no medical claims, you do not need a prescription to purchase a tDCS device. CES is FDA Cleared for the treatment Depression, Anxiety and Insomnia. CES devices require a prescription to be purchased. Online authorization can be obtained using an online telemedicine provider.
• What are the side effects of tDCS?
• During tDCS an itching sensation was the most common reported adverse effect, followed by fatigue, burning, numbness and redness in the electrode area and mild nausea. All the reported adverse effects associated with tDCS were short lived. These claims are based on publications and information found online. Caputron does not make any medical claims.
• Is tDCS FDA Cleared?
• tDCS is an investigational technology not yet cleared by the FDA. Some tDCS devices are cleared in the European Union for the treatment of depression, fibromyalgia and migraine.
