Why Timing Could Be the Missing Variable in Migraine Care

A new study from Theranica, by Ailani and colleagues, published in Cephalalgia [1] , adds fresh urgency to a longstanding clinical institution: in migraine treatment, timing isn’t just important—it’s decisive.

The study, one of the largest of its kind, analyzed real-world data from over half a million uses of Theranica’s remote electrical neuromodulation (REN) wearable device, Nerivio—a smartphone-controlled, FDA-cleared neuromodulation therapy for acute and preventive migraine treatment in children and adults (age 8+). 

The goal: to quantify the impact of treatment onset timing on clinical outcomes.

What emerged reaffirmed an old truth–this time, without drugs or systemic side effects

The Early Advantage

Clinicians have long suggested that patients treat migraine attacks early. [2] But what exactly does “early” mean–and how much does it matter?

In this new analysis, treatments initiated within one hour of migraine onset delivered dramatically better outcomes than those initiated later. Patients were more likely to be free from pain, from functional disability and from hallmark symptoms like nausea and photophobia.

These weren’t marginal improvements. They were the kind of gains that suggest a clinical inflection point—one hour after onset—where the effectiveness of acute therapy shifts substantially.

A New Paradigm, Reinforced by Real-World Behavior

This wasn’t a theoretical exercise or a tightly controlled randomized clinical trial. The findings come from real-world patient behavior: people treating real attacks, in real time, using a non-pharmacological device prescribed by their healthcare provider, which they control from their smartphones.

Over 55,000 individuals contributed to this dataset, across hundreds of thousands of attacks. The scale alone gives the findings weight—but it also speaks to something deeper. REN doesn’t just work when conditions are perfect as in controlled clinical trials. It works “in the wild” and it works better when people act early.

Rethinking What “Effective” Looks Like

Migraine treatment has long been dominated by pharmacological medications. But as wearable neuromodulation gains traction, the definition of effective care is expanding.

This data adds a new dimension to that shift. It doesn’t just confirm that REN provides relief without medication or side effects—it shows that timing is an efficacy multiplier. And that makes early access and early education as crucial as the device itself..

The Takeaway: Don't Wait

The findings from this study highlight a clear and compelling clinical insight.

Treating with REN as early as possible, at the onset of migraine symptoms, can significantly improve outcomes.

This mirrors guidance often given for pharmacological therapies which now extends to REN as well. Early treatment was associated with a substantially greater likelihood of pain relief, pain freedom, freedom from symptoms like nausea, sensitivity to light or sound and restoration of function–sometimes doubling the chance of success.

So “treat as early as possible, at the onset of your first migraine symptoms”. 

But while the message of “don’t wait” is clear, it’s equally important to underscore this: 

Even if the first hour has passed, it’s not too late.

REN still offers meaningful relief when used later in an attack. Every treatment matters, and every opportunity to reduce the burden of migraine counts.

The bottom line? The best time to treat is as early as possible. The second-best time is now.
