Transcutaneous Vagus Nerve Stimulation (tVNS)

Stimulating the body's own calming pathway to treat the brain.

What Is tVNS?

The vagus nerve is the longest cranial nerve in the body, connecting the brain to the heart, lungs, gut, and immune system. It plays a central role in regulating mood, inflammation, and the stress response.

Transcutaneous vagus nerve stimulation (tVNS) delivers gentle electrical stimulation to a branch of the vagus nerve accessible through the ear. It is non-invasive, painless, and does not require surgery or implantation.

What Does tVNS Treat?

  • Depression — modulates brain circuits involved in mood regulation
  • Anxiety — activates the parasympathetic nervous system to reduce the stress response
  • Inflammation — the vagus nerve is a key regulator of the body's inflammatory response
  • Chronic pain — modulates pain processing pathways
  • Autoimmune conditions — emerging evidence for conditions driven by inflammatory processes
  • PTSD — helps regulate autonomic nervous system dysregulation

How It Works

A small device delivers mild electrical stimulation to the auricular branch of the vagus nerve in the ear. This signal travels to the brainstem and activates pathways that influence mood, arousal, inflammation, and autonomic function.

Why tVNS at BrainHope

We integrate tVNS into a broader treatment approach that includes brain measurement (EEG, HRV) and other stimulation modalities. Rather than using tVNS in isolation, we use it as part of a personalized, multi-modal strategy.

Heart rate variability (HRV) monitoring allows us to track vagal tone and assess treatment response objectively.

What to Expect

  • A small clip-like device is placed on the ear
  • Stimulation feels like a mild tingling or pulsing
  • Sessions last 15 to 30 minutes
  • No side effects for most patients
  • Can be used at home between office visits

Electrical Stimulation

Gentle electrical currents to modulate brain network activity.

What Is Electrical Stimulation?

Transcranial electrical stimulation delivers low-level electrical currents through electrodes placed on the scalp. These currents influence the activity of neurons in targeted brain regions, helping to restore balance in dysfunctional networks.

Unlike TMS, electrical stimulation is quieter, more portable, and can be used to modulate brain activity in ways that complement other treatments.

Types of Electrical Stimulation

tDCS — Transcranial Direct Current Stimulation

Delivers a constant, low-level current to increase or decrease neural activity in a targeted region. Used for depression, cognitive enhancement, and chronic pain.

tACS — Transcranial Alternating Current Stimulation

Delivers oscillating current at specific frequencies to entrain brain rhythms. Used to target specific neural oscillations associated with symptoms.

CES — Cranial Electrotherapy Stimulation

FDA-cleared for anxiety, insomnia, and depression. Delivers microcurrent stimulation that influences neurotransmitter activity.

Trigeminal Nerve Stimulation (TNS)

Stimulates the trigeminal nerve to modulate brain activity. FDA-cleared for ADHD and used off-label for depression and PTSD.

Our Approach

We use EEG to identify the specific brain rhythms and network patterns that need modulation, then select the electrical stimulation method and parameters most likely to help. This is not a generic protocol — it is tailored to your brain.

Electrical stimulation is often combined with TMS and medication for a comprehensive, multi-modal treatment approach.

What to Expect

  • Sessions are painless — most patients feel only a mild tingling sensation
  • Treatment duration varies from 20 to 40 minutes per session
  • No anesthesia required, no recovery time
  • Can be used alongside other treatments

In addition to Magnetic (rTMS), there are other brain stimulation options: 

1   tACS (including CES) = transcranial Alternating Current Stimulation

(or Cranial Electrotherapy Stimulation) 

2   tDCS = transcranial Direct Current Stimulation 

3   tTNS = transcutaneous Trigeminal Nerve Stimulation 

4  tVNS = Transcutaneous Vagus Nerve Stimulation

5  Light Therapy = For Seasonal Mood Disorder (SAD), Major Depression (MDD) & PMDD (PMS)

6  TENS = Transcutaneous Electric Nerve Stimulation

 

These completely different from "shock" therapy (ECT). and there are 3 differences (advantages) vs ECT:

1) ECT uses 450 volts at 1 amp current, these use about .002 amps (2 milliamps) (500 times less current)

2) no anesthesia is needed, patients are awake and drive to and from appointments

3) These may Improve Memory (ECT can impair memory)
