MIGRAINE AND HEADACHE
More than a headache.
Migraine is a specific headache disorder with recurring attacks. A diagnosis depends on the pattern of symptoms and clinical assessment.
Recurring attacks
Head pain may be moderate or severe and interfere with ordinary activities.
Light and sound sensitivity
Everyday light, noise and busy environments can become harder to tolerate during an attack.
Nausea and fatigue
Nausea, tiredness and difficulty concentrating can affect the day, including time around an attack.
Disrupted plans
Unpredictable attacks can interrupt work, relationships and activities that matter to you.
EAR-BASED STIMULATION
Why researchers study vagal pathways.
The vagus nerve carries information toward the brainstem, where networks involved in pain processing interact. Researchers are exploring whether stimulation at the outer ear (taVNS) can influence migraine-related outcomes.
Migraine involves several interacting pathways. Vagal stimulation is one research approach, rather than a single explanation for migraine.
taVNS RESEARCH
What the migraine trial found.
A randomized trial compared two active taVNS frequencies in chronic migraine.
RANDOMIZED ACTIVE-COMPARISON TRIAL · 2015
Two ear-based frequencies compared.
In 46 people with chronic migraine, Straube 2015 compared two active ear-based frequencies. Among participants who followed the protocol, headache days fell more with 1 Hz than with 25 Hz.
The difference between groups was not statistically significant in the analysis of all randomized participants. This was not a sham comparison. Stimulation lasted four hours daily for twelve weeks, not a Neuvago session.
Read Straube 2015These studies used their own taVNS devices and protocols and did not evaluate Neuvago.
NEUVAGO
Room for calm between daily demands.
Neuvago delivers gentle ear-based stimulation designed to support relaxation and everyday wellbeing. A quiet pause can fit around the demands of your day; it is not a migraine treatment.

When a headache needs urgent medical assessment.
Some headache patterns need prompt or emergency medical evaluation.
Seek emergency medical care for a sudden, severe headache that reaches maximum intensity within seconds or minutes.
Seek urgent help for a headache with new weakness, numbness, difficulty speaking, confusion, seizure, loss of consciousness or new vision loss.
Seek urgent help for headache with high fever or neck stiffness, or after a recent significant head injury.
Prompt medical assessment is also important for a new or markedly changed headache pattern, progressive worsening, or symptoms that are different from a person's usual migraine.
New headache during pregnancy or the postpartum period, or in a person with cancer or immune suppression, also requires medical assessment.
New neurological symptoms may sometimes resemble aura, but first-time, clearly different or unusually prolonged symptoms should be assessed promptly. This list is not exhaustive.
