Clinical Research: Brain Stimulation
The Flow brain stimulation treatment is based on decades of clinical research with the most recent meta-analyses showing that tDCS has similar efficacy to other treatments but with fewer side effects
Across 20+ randomized controlled trials tDCS has been shown to be superior to placebo/sham and no serious adverse events have been observed. Hence, tDCS provides an alternative to medication that is effective, safe and accessible.
Clinical Research: Behaviour Therapy
The Flow therapy app is based on a hundred years of psychological research, showing that exercise, sleep, diet and meditating all have an impact on reducing depressive symptoms when incorporated into a regular routine.
Research shows that regular exercise is as effective as antidepressant medication. It increases positive mood and stimulates growth of new brain cells.
The latest research gives you the recipe for an antidepressant diet. Changing your eating habits can prevent the development of depression and reduce depressive symptoms.

tDCS and depression
tDCS has shown across years of research to be effective in reducing depressive symptoms. With world-leading tDCS researcher Andre Brunoni highlighting that tDCS works best through 30-minute sessions, 2-5 times per week. In terms of adverse experiences, recent meta-analyses indicate that this type of treatment has low risk, with over 33200 stimulation sessions showing no serious effects.
Flow and depression
Clinical Research Pillars
As part of our commitment to the field of brain stimulation and mental health, we are focused on creating accessible solutions globally that have an impact.
“The Future of neuromodulation is in our hands”
We’re thrilled to announce our acquisition of Halo Neuroscience’s technology
Innovating neuromodulation for mental health disorders, our co-founders Daniel and Erik explain:
“Our aim is to improve the lives of people who struggle with their mental health. Halo’s advanced technology and academically backed research will help us to further develop treatments for a variety of mental health issues using the power of a remote, accessible brain stimulation”
will support progress as an advisor to Flow:
“Flow is the best possible successor and a great home for everything we built at Halo with the help of our team, our customers, and our collaborators. We’re looking forward to seeing Flow’s research and technology advance the state of the art in neuromodulation and make an enormous impact on mental health worldwide with efficient, patient-specific, precision treatment.”

The science behind Flow
Flow and the brain
- Depression is associated with lowered activity in a brain area called the DLPFC (Dorsolateral Prefrontal Cortex). It’s located in the frontal lobe.
- The Flow headset delivers gentle electrical signals to the DLPFC to help activate the brain cells. As a result, depressive symptoms decrease or disappear.
- The technology used in the Flow headset is called transcranial Direct Current Stimulation (tDCS).
- World-leading tDCS researcher and assoc. Professor of Psychiatry, Andre Brunoni, has found that tDCS works best through 30-minute sessions, 2-5 times per week.
Studies on tDCS and depression
The technique used in the Flow headset is solely based on results from RCT* studies, conducted without funding from Flow Neuroscience. One such study included 245 participants with depression. It was conducted in 2017 and showed that 41% of depressed people noticed that at least half of their symptoms disappeared within 6 weeks of using brain stimulation. Only 22% of people in the placebo group experienced similar results.

Studies on tDCS and safety
Among many others, a meta-analysis* conducted in 2016 showed that the technique used in the Flow headset is safe and has never been associated with brain damage. The analysis included 1000 research participants and over 33,200 stimulation sessions!
*A meta-analysis is a research method that combines results from multiple studies. This means that the results from a meta-analysis are particularly reliable.

The therapy app
To maximize your chances of recovering from depression, the brain stimulation is combined with behaviour therapy delivered through the app Flow – Depression. The therapy focuses on lifestyle changes that significantly reduce symptoms of depression. Naturally, the facts and techniques presented in the treatment programme are based on RCT (Randomised Controlled Trial) studies and developed by clinical psychologists.
