How it works
A non-invasive headset
Research shows that depression is linked to reduced activity in key areas of the brain that regulate mood and emotion. Flow works with your brain's natural electrical signals to gently stimulate these regions, helping to relieve depression symptoms.
While traditional treatments focused on chemical imbalances, modern neuroscience has revealed that depression is more complex. Recent research shows that directly targeting brain activity can be an effective approach to managing depression symptoms.
Used by the NHS
to treat depression
You can access a Flow trial if you live in West London, Northamptonshire or Leicestershire and you meet the qualifying criteria, or if you are an NHS clinician suffering from depression.
Every NHS service using the headset has independently published their findings, demonstrating that Flow is safe and effective to use. A Crisis Service reported up to a 75% drop in feelings about self harm and suicide when patients were using the headset.

Flow uses a technology called tDCS (or transcranial Direct Current Stimulation). This has been used in clinics for over 25 years, and has been proven to be safe and effective across multiple independent trials.
