What is VNS?

The vagus is the key component of the parasympathetic branch of the autonomic nervous system, and because the sympathetic and parasympathetic nervous systems act reciprocally -- when one goes up, the other goes down -- the vagus nerve is critical in many therapeutic areas due to its beneficial effect in restoring balance in cases where sympathetic activity is abnormally raised or parasympathetic activity is lowered.   


Researchers are investigating:  VNS mechanisms of action, restoration of autonomic balance, laying new neural pathways during tasks, reduction of symptoms and systemic imflammatory responses and much more...

 Why does Ptsd matter?

PTSD is a devastating psychiatric disorder caused by exposure to a horrific or life-threatening trauma.  People with PTSD have difficulty sleeping, nightmares, persistent frightening flashbacks, sudden pathologically-intense outbursts of anger, violence, or anxiety, feel numb or detached, and avoid “triggers” (people or places that remind them of the trauma).

The clinical, social, and financial burdens are enormous.  The annual cost to society is estimated at over $232 billion. In the VA alone more than 900,000 veterans receive PTSD disability compensation.

What are the Unmet medical Needs?

There is no cure, and current treatment options are inadequate. Over 12 million Americans have PTSD; 4.2 million of them (35%) never seek help and of the remainder who do seek treatment, few are satisfied with the result.  Among those treated, approximately 2/3 (66%) retained their PTSD diagnosis after treatment.  Only 9% feel fully recovered. Thus, there is an unmet need affecting about 9 4 million Americans with PTSD.
