The U.S. Food and Drug Administration has approved the first at-home brain‑stimulation device intended to treat depression, a decision that shifts part of psychiatric care out of clinics and into people’s living rooms.
Flow Neuroscience, a neurotech startup, makes the headset: a wearable that delivers weak electrical currents to the dorsolateral prefrontal cortex, a brain region linked to mood regulation. The technique—transcranial direct current stimulation, or tDCS—is not new to labs, but this is the first time the FDA has cleared a device of this kind for unsupervised home use with a prescription.
What the approval is based on
Regulators pointed to a 2024 phase‑2 trial of 174 adults in which participants used the headset in 30‑minute sessions across about 10 weeks and reported greater symptom relief than control participants. The FDA described the benefit as modest but concluded it outweighed probable risks, noting headaches and skin irritation among the main side effects.
Supporters call the move a practical expansion of options for people with moderate to severe major depressive disorder—particularly for those who haven’t responded to medications. "It expands the therapeutic landscape in a space that sorely needs more accessible interventions," said Robert Reinhart, an associate professor at Boston University, who was not involved in the trial.
Why some scientists remain cautious
Skepticism remains. A high‑profile 2023 Lancet trial found tDCS no better than placebo, and entry‑level studies over the past two decades have produced mixed results. Some positive trials, including those sponsored by Flow, have shown benefit, raising the familiar question about funding and potential bias.
Researchers emphasize several unknowns: how long improvements last, which patients benefit most, and how the at‑home setting affects outcomes compared with supervised clinic treatments such as repetitive transcranial magnetic stimulation (rTMS) or electroconvulsive therapy (ECT). The agency’s green light is limited to adults with moderate to severe depression and requires a prescription.
Access, cost and practical questions
Flow has said the device will likely sell for roughly $500–$800, and the company is in talks with insurers about coverage. For some patients, the lower price and the convenience of home use could remove logistical barriers—no commute to a clinic, no daily appointments. For others, remote use raises safety and oversight questions: how will clinicians monitor adherence, handle adverse effects, or confirm device placement and usage?
Clinicians and regulators will be watching how prescribing workflows adapt. Tech tools that help schedule or manage care are already changing patient interaction models—for example, recent advances in booking wellness appointments and AI‑driven care coordination. At the same time, the intersection of consumer tech and health data invites scrutiny about privacy and data security—issues similar to those raised by other large AI integrations into personal platforms, like the debate around privacy questions with data‑driven services.
The bigger picture: more options, not a miracle cure
Erin Lee, Flow’s CEO, described the FDA approval as a watershed moment for moving beyond pharmaceuticals to tech‑based therapies with fewer systemic side effects. That optimism is tempered by calls for more robust evidence. Experts urge post‑market studies, longer follow‑ups, and head‑to‑head comparisons with established treatments to map who benefits most.
For patients and clinicians, the approval means another tool in the toolkit—one that could improve access and patient choice. It also underscores a growing trend: medical devices that sit at the crossroads of consumer wearables, clinical care and digital health platforms. How this device performs in the messy reality of everyday use—outside controlled trials, within diverse health systems, and under varying insurance models—will determine whether it’s a transformative option or simply another incremental step.
