Often times depression can get so severe that we stop going out with friends, spend more time in bed, and generally lose our sense of self. Depending on the area of the brain that’s being stimulated, the results can vary from reduced depression, to pain relief or even memory improvement! Types electrode placements used for the tDCS procedure in bipolar depression. I am aware of the different placements but I'm curious as to what others have personally experienced, and which montage you have found to be most helpful. Electrode Placement System Explained Sooma tDCS offers a complete therapy solution indicated for the treatment of Major Depressive Disorder, Chronic Neuropathic pain, and Fibromyalgia. *Disclaimer - tDCS is classified as investigational technology by the US Food and Drug Administration (FDA), therefore tDCS does not have any medical indications for treatment of any kind. The negative electrode is sometimes called the “anchor” or “reference” electrode, and is where the current leaves the body. Research into Transcranial Direct Current Stimulation’s and its potential as a non-pharmacological treatment option for depression dates back as far as the 1960’s. The effectiveness of tDCS decreases with resistance to treatment. Coding recommendations. Study Results: Improved Mood, Reduced Depression, Reduced Anxiety. One approach increasingly investigated for major depression is non-invasive brain stimulation. TRD is defined as two or more failed antidepressant trials. I tried everything to make it stop, from therapies to drugs, nothing seemed to work. In that context, let’s have another look at tDCS for bipolar depression. I personally suffer from depression and looking back, I am amazed at how much it affected my life. Do not view the data presented herein as absolute fact. Transcranial direct current stimulation in treatment resistant depression: a randomized double-blind, placebo-controlled study. As stated above, this tDCS placement targets the Primary Motor Cortex (M1). Anode (+) RED Electrode Placement. Analysing these high-standard studies revealed that tDCS seems to reliably improve the symptoms of depression, addiction and craving, and fibromyalgia. Any new treatment option is worth examining-especially if it does not have the antidepressant- associated risk of inducing mixed states and rapid cycling, with their associated increased suicide risk. Sing your heart out. One notable study utilized 1mA of current for 20minutes, every other day for 5 days. The exact placement is: Anode Electrode (marked red) —> Primary Motor Cortex (above left ear) Cathode Electrode … Medical devices are controlled differently in Canada, the EU, and the U.S. About tDCS devices… In Canada, it is not considered a medical device when used in a cognitiveneuroscience application.

Depression is a mental illness that affects 1 in 10 people according to the Centers for Disease Control and Prevention. We here show a small subset of different alternatives for placement of electrodes in tDCS applications such as depression and modulating pain. For positioning the electrodes, it is helpful to fall back to the international 10/20 EEG-system. Depression presents a major burden to global health, affecting more than 300 million people [1]. It has been well documented that Transcranial Direct Current Stimulation (tDCS) applied using this electrode placement montage has ability to produce improved mood in those suffering with depression. Through rigorous research and testing, scientists have shown that Transcranial Direct Current Stimulation (tDCS) can actually reduce or completely remove feelings of anxiety and stress. While early research struggled to determine optimal electrode placement, current tDCS research focuses on Anodal stimulation of the Dorsolateral Prefrontal Cortex and Cathodal stimulation of the right Supraorbital area, as the benefits produced from this placement far outweigh those of other montages. The solution features a high-quality stimulation device, accessories that ensure dose precision and replicability, and a software platform designed to enable remote monitoring. These sponge electrodes are wetted then placed on specific parts of the head depending on the desired result. Findings also indicate that tDCS is effective in patients with mild to moderate depression that is not treatment-resistant. It benefits in many disorders such as Schizophrenia, Depression, Obsessive-Compulsive Disorder, Alzheimer’s, Migraine, Parkinsonism etc. When using Transcranial Direct Current Stimulation (tDCS), where you choose to place the electrodes on your head is very important. The canonical way to increase excitability of the left DLPFC (which is what's believed to hep with depression) is to place the anode over F3 and the cathode over the right eye. This double-blind clinical trial contained 40 patients with major depression not currently taking medication for their symptoms. In the left hemisphere (in the dorso- lateral prefrontal cortex, DLPFC) the neuronal activity is reduced. In the EU, tDCS is classified as a safe and effective treatment for depression, fibromyalgia and migraine. Evidence-based guidelines on the therapeutic use of transcranial direct current stimulation (tDCS), Zapping the brain really does seem to improve depression, Depression and tDCS – A powerful way to defeat depression. The different electrode positions for tDCS are commonly referred to as montages. tDCS plays a crucial role in enhancing brain function and subsequently modifying human behavior. I have been doing the left DLPFC, right supraorbital placements but haven't noticed a huge difference in my symptoms. There are many motor strip studies showing that anodal stimulation at C3 or C4, with a contralateral obit reference, enhances fine motor control, while cathodal stimulation impairs it. Transcranial direct current stimulation: a promising alternative for the treatment of major depression? Those who received active tDCS stimulation displayed a 42.1% reduction in their BDI scores, compared to only a 15% BDI score reduction in patients who had been taking Fluoxetine for the same period of time. Every up-to-date tDCS electrode montage out there, with electrode placement instruction using the 10/20 system--along with notes for each montage as well as their respective sources and publications. It wasn’t until after 6 weeks of administration that both groups displayed a similar reduction in BDI scores, showing depression relief was experienced markedly faster with Transcranial Direct Current Stimulation compared to  Fluoxetine administration.2. This montage uses 2 electrode placements, the anode is placed over the Fp1 zone and cathode can be placed over either CZ or OZ. Most commonly a current of 1-2mA is applied to the scalp using 3×3″ electrodes, for approximately 20 minutes at a time. RELATED INFO: Natural supplements such as Turmeric and Curcumin also have known anti-anxiety and anti-depressive properties. This is possibly the most researched tDCS montage, and there's pretty good evidence that it does, indeed, target the left DLPFC. Transcranial direct current stimulation for depression: 3-week, randomized, sham-controlled trial. 11,17 The adverse effects associated with tDCS appear to be mostly limited to headaches and itchiness and redness at the site of stimulation, which are significantly less severe than the cognitive effects associated with other brain stimulation treatments, such as ECT. Bipolar depression is often difficult to manage. tDCS devices usually come with cables attached to two “electrodes,” often made from a sponge-like material. These montages usually stimulate (positive electrode, “anode”) the primary motor cortex, located just above the left temple.
