Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy , cluster headaches, treatment-resistant depression and stroke rehabilitation.
Transcutaneous stimulation of vagus nerve through the ear [4] proved to reduce symptoms of that family (long lasting, on the way of the vagus nerve) according to a study realized in the context of long covid. [2] Botox injections may temporarily disable the muscle and provide relief for 3–4 months per injection. [5]
A vagal maneuver is an action used to stimulate the parasympathetic nervous system by activating the vagus nerve.The vagus nerve is the longest nerve of the autonomic nervous system and helps regulate many critical aspects of human physiology, including heart rate, blood pressure, sweating, and digestion through the release of acetylcholine.
This type of vagus nerve stimulation device was approved for treatment-resistant depression nearly two decades ago by the US Food and Drug Administration, but did not become widely available.
Vagus nerve stimulation therapy improved the symptoms of treatment-resistant depression for nearly 500 participants in a major clinical trial.
The primary findings about neurostimulation originated from the idea to stimulate nerves for therapeutic purposes. The 1st recorded use of electrical stimulation for pain relief goes back to 46 AD, when Scribonius Largus used torpedo fish (electric ray) for relieving headaches. [47]
Finally, there is the critical presence of afferent output to the Vagus nerves as a direct result of eye muscle stretch or traction. [30] Thus, tenth nerve stimulation resulting from eye muscle stretch is proposed as the cause of motion sickness.
In contrast, pseudobulbar palsy is a clinical syndrome similar to bulbar palsy but in which the damage is located in upper motor neurons of the corticobulbar tracts in the mid-pons (i.e., in the cranial nerves IX-XII), that is the nerve cells coming down from the cerebral cortex innervating the motor nuclei in the medulla.
