What is tDCS?

Transcranial Direct Current Stimulation (tDCS) is the technique used in the Flow tDCS device. This type of brain stimulation has been used to treat depression for decades, but should not be confused with electroconvulsive therapy (formerly known as electroshock therapy). The current used in tDCS is 400 times weaker and has never been associated with serious adverse events. The Flow tDCS device delivers a constant low-strength electric current through two electrodes placed on the forehead to stimulate brain activity and help improve the symptoms of depression. In the largest tDCS study to date, 24% of patients completely overcame their depression, while 41% found that at least half of their symptoms disappeared after six weeks using this technique (read more about the Science).

How to use the Flow tDCS headset

The Flow tDCS device is Bluetooth controlled and managed through the Flow depression app. Consequently, the first thing to do is to download the app Flow – Depression.  Inside the app you will meet your virtual therapist, Flow, who guides you through the treatment programme. The app will give you step-by-step instructions on how to start the headset, put it on and begin your first stimulation session. 

This video will tell you more about the Flow tDCS headset:

The treatment protocol. It’s important to follow the tDCS treatment protocol to get the best effect. Your stimulation sessions are 30 minutes long and you will start with 5 sessions per week during the first two weeks. After that, there will be 2 sessions per week for as long as you like. Your virtual therapist will help you schedule all upcoming sessions. Also, the app offers you over 50 Behaviour Therapy sessions with a focus on lifestyle changes that significantly decrease symptoms of depression. (Read more about the Flow – Depression app.)

Is the Flow tDCS device going to help you?

Like other treatments for depression, brain stimulation works very well for some people, but for others, it does not work at all. That’s why it’s always best to combine using the Flow tDCS device with the lifestyle changes suggested in the Flow depression app (link to page). We want to maximize your chances of recovering from depression. After about 3-4 weeks, you will be able to feel a reduction of your symptoms if this is a treatment that works for you.

Are there side effects from using the tDCS device?

Clinical trials published in the New England Journal of Medicine and the British Journal of Psychiatry showed that tDCS brain stimulation, of the kind used in the Flow tDCS device, had a similar impact to antidepressants, but with fewer and less-severe side effects. Some people don’t feel anything underneath the electrodes. Some people feel an itchy, slightly tingling sensation. Some feel stinging or a mild burning sensation and some experience mild headaches that pass after half an hour. (Read more about Safety and Precautions.)
