Flow At-Home Brain Stimulation for Depression

Flow is a headset that delivers transcranial direct current stimulation (tDCS) — a low, steady 2 mA current directed at the front of the brain — during 30-minute sessions guided by a smartphone app. It is used at home, on a prescription, as part of the treatment of depression. You can read more on the manufacturer's site at flowneuroscience.com.

Flow is often discussed with adults whose depression has not fully responded to medication alone, who prefer a non-medication option alongside their current care, or who cannot tolerate certain medications. It is not appropriate for everyone — implanted devices, certain neurological conditions, and skin conditions on the scalp are among the reasons a provider may advise against it. Eligibility is decided during an evaluation, not online.

• A psychiatric evaluation to review your history and current treatment.
• A decision together about whether Flow is a reasonable option for you.
• A roughly 10-week program: five 30-minute sessions per week for three weeks, then three sessions per week for seven weeks.
• Follow-up visits to track your response and adjust the overall plan, including medication management when relevant.

In the published trial, a majority of participants improved and many reached remission, with most participants continuing a stable antidepressant during the study. Those results describe a group, not a promise for any one person. Side effects are generally mild and temporary — tingling, itching, or redness under the electrodes, sometimes headache or fatigue. If Flow is not helping, we say so and revisit the plan. Our detailed write-up is here: our guide to Flow at-home treatment.
