Summary

This trial is testing a treatment called trigeminal nerve stimulation, which involves sending electrical signals to a nerve in the face. It aims to help patients with panic disorder, generalized anxiety disorder, and social anxiety disorder. The treatment works by calming brain activity to reduce anxiety symptoms. Trigeminal nerve stimulation (TNS) is a promising strategy in treating diseases of the nervous system, including epilepsy and traumatic brain injury.

Who is the study for?
This trial is for individuals who have been diagnosed with panic disorder, social anxiety disorder, or generalized anxiety disorder according to DSM5 criteria. It's not specified who can't join the trial.
What is being tested?
The study is testing trigeminal nerve stimulation (TNS) as a treatment for various anxiety disorders. Participants will receive either active TNS or a sham (placebo) version to compare effectiveness and tolerability.
What are the potential side effects?
While specific side effects are not listed, TNS is generally considered low-risk. Potential side effects might include discomfort at the stimulation site or mild headaches.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Active stimulationExperimental Treatment1 Intervention
Active or sham TNS treatment will be performed at the patients' home for approximately 8 hours per night 7 days a week for 8 consecutive weeks. Trigeminal nerve stimulation will occur by placement of electrodes (1.25" silver electrodes Bio-Flex BF4, Biotens/Vermed, Buffalo, NY, USA) bilaterally on the V1 branches of the trigeminal nerve (CNV) located on the forehead. Current will be generated from the EMS 7500 stimulator (TENS Products, Inc., Granby, CO) (Class II medical device) and will be set to a level that is clearly perceptible by each patient (i.e. tingling sensation) but not uncomfortable or painful. Current level will be determined for each patient at baseline and will likely be between 4-6 mA. Active stimulation will occur at 120 Hz with a 250 µs pulse width and with a duty cycle of 30 seconds on to 30 seconds off.
Group II: Sham stimulationPlacebo Group1 Intervention
Active or sham TNS treatment will be performed at the patients' home for approximately 8 hours per night 7 days a week for 8 consecutive weeks. Sham stimulation will occur by placement of electrodes (1.25" silver electrodes Bio-Flex BF4, Biotens/Vermed, Buffalo, NY, USA) bilaterally on the V1 branches of the trigeminal nerve (CNV) located on the forehead. Current will be generated from the EMS 7500 stimulator (TENS Products, Inc., Granby, CO) (Class II medical device) and will be set to a level that is clearly perceptible by each patient (i.e. tingling sensation) but not uncomfortable or painful. Current level will be determined for each patient at baseline and will likely be between 4-6 mA. Sham stimulation will use the same parameters of active stimulation, but after 60 seconds the stimulator will turn off.

Other Research
Common treatments for Panic Disorder include selective serotonin reuptake inhibitors (SSRIs), benzodiazepines, and cognitive-behavioral therapy (CBT). SSRIs work by increasing serotonin levels in the brain, which helps regulate mood and anxiety. Benzodiazepines enhance the effect of the neurotransmitter GABA, providing quick relief from acute anxiety symptoms. CBT focuses on changing negative thought patterns and behaviors associated with panic attacks. Trigeminal Nerve Stimulation (TNS) is being studied as a treatment that modulates neural activity in the trigeminal nerve to alleviate anxiety symptoms. This is significant for Panic Disorder patients as it offers a potential non-pharmacologic option that directly targets neural pathways involved in anxiety, potentially reducing side effects associated with medications.
