After being diagnosed with depression, it is normal to wonder, what can I do to feel better? Treatments come in many forms - from lifestyle changes to prescription medicines. However, there isn’t a treatment type that is suitable - or even works - for everyone.

More than 60% of people taking prescription antidepressants experience at least 10 side effects, and some of them are pretty severe. At the same time, psychotherapy is not always accessible, or desirable.

Even if a depression treatment does have a positive effect, it probably won’t treat all symptoms. Most likely, it will take a mixture of several approaches to fully recover from depression.

Finding the combination of treatments that will produce the best results for you takes a bit of trial and error. If the treatments you’ve tried haven’t been effective or right for you, there’s still hope.

While medication and psychotherapy are the most common treatments, they are far from the only ones available. One option that stands out has:

  • No severe side effects
  • No waiting lists
  • And is as effective as other antidepressant treatments

This evidence-based treatment is known as transcranial Direct Current Stimulation, or simply, tDCS.

tDCS is a versatile treatment option. It can be used alone or in combination with other treatment approaches. If you haven’t heard of tDCS before, it’s probably because for many years it was only available in a clinical setting.

Today, there is a medically-approved tDCS device for home use, and it is available online without a prescription.

Before we go further into that, let’s back up and talk about the technology behind tDCS.

tDCS: The History

tDCS is a type of depression treatment known as brain stimulation. This means that it interacts with brain cells and nerves through a very mild electric current. While this wouldn’t be out of place in a sci-fi movie, tDCS is actually quite an old technology.

Ancient Romans used the currents emitted by electric fish to treat nerve pain, and tDCS was first used as an effective depression treatment way back in the 19th century.

tDCS headsets have been used by psychologists and mental health clinicians since the 1970s. And in 2019, Flow Neuroscience had created the first medically-approved tDCS headset for at-home use.

The Flow tDCS headset has undergone rigorous IEC compliance and European Union CE-mark testing. The device also has important safety features that eliminate the risk of adverse side effects.

Anyone with a clinical diagnosis of Major Depressive Disorder (depression) can try Flow — it doesn’t require a prescription or a doctor’s approval.

tDCS vs TMS vs ECT: What’s the Difference?

Besides tDCS, there are other treatment protocols that relieve depressive symptoms through brain stimulation. The best-known are:

  • Electroconvulsive Therapy (ECT)
  • Transcranial Magnetic Stimulation (TMS)

While both ECT and TMS are used for depression, they are very distinct treatments that are recommended under very different circumstances.

ECT is reserved for the most severe cases of treatment-resistant depression. It can only be performed in a clinical setting and under the direct supervision of a medical professional. ECT is helpful and highly effective but has significant side effects such as memory loss. For this reason, it is usually only used as a last-resort treatment.

TMS is a much milder treatment than ECT and uses magnetic fields rather than electricity to stimulate the brain. TMS is effective, non-invasive, and well-tolerated (although there is a minuscule chance of serious side effects). However, it can only be done in a medical setting. Most people will need at least 30 once-per-day sessions to see a change in their symptoms.

tDCS, like TMS, is also mild and non-invasive. However, tDCS has no severe side effects. While most tDCS treatments are designed for clinical use, the Flow tDCS device is portable and battery-powered, making it possible to undergo treatment at home.

How Does Flow tDCS Treat Depression?

The Flow tDCS device resembles a headset or small headband with two electrodes. During a session, these electrodes will go on either side of your forehead and send out a minor electric current. This passes through the dorsolateral prefrontal cortex (DLPFC) – a brain area that often under functions in patients with depression (specifically the left side of the DLPFC).

The current helps neurons in that region to “fire up” and make them more active. A more active DLPFC can raise your mood and reduce your depressive symptoms.

This effect is so strong in fact, that research shows that tDCS is as effective as other types of antidepressant treatments. In some studies, tDCS have made SSRIs (a common type of antidepressant) even more effective.

What Is It Like To Use a Flow tDCS Headset?

If you’re curious about tDCS, you can rent a Flow headset online and get it delivered to your door. You can take the device right out of the box, charge it, and use it within the same day. Before you begin your first session, download the Flow app.

When you look at the headset, you will see two holder rings, which fit two circular sponges. These holder rings are electrodes and will fit on either side of your forehead. In the app, you will find a helpful instruction video that walks you through the process of placing the headset correctly.

Once you press the start button on the app, you’re all set. The electrodes will start to emit a very low voltage current. This may sound intense but don’t worry, tDCS sessions are typically painless.

You might feel a slight tingling or warming sensation on your skin. This is normal and will stop as soon as you are done with your session. Also, you will probably notice that this reaction will fade as you get used to the device.

During the session, you can do any of your usual activities. Some people like to draw, knit, watch T.V., read, or just relax. A typical session lasts around 30 minutes, and the headset will shut off by itself.

When you’re done, you might notice a boost in your mood or energy right away. Following your first session, you will need to continue tDCS sessions 5 times a week for 3 weeks. After that, you can scale back and do sessions a couple of times a week.

If you’d like, you can combine the headset with the Flow in-app treatment program, which will help you make important lifestyle changes, like improving your sleep quality and nutrition. The in-app treatment program also contains meditation exercises and suggestions for incorporating more movement into your life.

Like the headset, you can use the Flow in-app treatment program on its own, or in combination with other treatments. You can do whatever works for you and your lifestyle.

So, tDCS is an approach that can help you tip the scales when it comes to managing your depression. If you are thinking of trying tDCS, the Flow headset is the safest and easiest way to see if it is right for you.
