Vagus Nerve Anal Stimulation
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
Seizure Treatment: Vagus nerve stimulation involves the surgical implantation of a small device, similar to a pacemaker, in the chest with wires under the skin which are wrapped around the vagus nerve in the neck. Vns has been found effective in the treatment of some patients with seizures. ...Read more
VNS: Is a type of highly successful neuromodulation therapy for refractory seizures and depression. In the future VNS therapy will be used for CHF and likely other conditions. Tiny electrical impulses are delivered to the Vagus Nerve in the neck to modulate brainstem activity in the case of VNS for seizures and depression. ...Read more
What is inappropriate stimulation of the vagus nerve and how to prevent it? Is it true it may create some physical symptoms of anxiety?
Straightforwards: To install this device to control epilepsy, the surgeon inserts a small stimulator device over the left upper chest wall, then connects to the left vagal nerve, and closes, a process of about 25-40 minutes. The device is turned on and initially programmed 2 weeks post-op, and is fully programmed over about 3-4 months. ...Read more
Does gerd/acid reflux always cause stimulation of the vagus nerve? If yes, are symptoms of stimulation different from those of anxiety?
Interesting question. Symptoms of stimulation of the vagus nerve are not usually associated with anxiety. The vagus nerve has many functions and I won't go into all of them here do to space limitations.
Reflux can cause stimulation of the nerve and chest pain and synocope/near synocpe (passing out) can happen but that's often in severe cases and usually with cold/hot beverages/drinks. ...Read more
Very brief issue: Typically, within 2-3 weeks, post-operative bruising or local tenderness is mostly gone, and unlikely any sensitivity will remain by 6 weeks. If you note swelling, reddening, or warmth at the op sites, contact your surgeon. Otherwise, you should recover uneventfully. ...Read more
Lukewarm option: Vagal nerve stimulation (vns) for treatment resistant depression is fda approved (2005). However, subsequent studies have not been too supportive of its use. There are many medication options and combinations these days as well as transcranial magnetic stimulation (less invasive) and electroconvulsive therapy (still an effective treatment). ...Read more
VNS: Units are set for on and off periods, and are not 100 % perfect, even when optimally programmed. A magnet is included, and if swiped across the vns device, will cause it to fire, and perhaps stop the seizure. If you sleep with a partner, the other can stop the seizure activity, but, if you sleep alone, the seizure will likely complete, but maybe the unit will decrease frequency well over time. ...Read more
What percentage of epilepsy patients are good candidates for vagus nerve stimulation (vns) therapy?
VNS candidates: Must be at least 12 years old (in the US) and have seizures that are known to respond to VNS (eg. Focal seizures, secondarily generalized seizures) and have failed to achieve adequate seizure control with at least two anticonvulsants (with documented therapeutic levels) or a combination of medications. Typically they are not good epilepsy surgery candidates. In my practice: about 1/3 patients. ...Read more
120bpm, breathing shallow & heavy, with both arms trembling post 3 BMs in succession. It has since normalized. Vagus nerve stimulation?
VNS?: Vagal Nerve Stimulation is used in the management of medically refractory epilepsy and depression. Perhapse you are thinking of Vaso vagal syndrome due to valsalva can occur when straining to have BM. Make sure you are not constipated from the Tylenol (acetaminophen) with codeine. Keep well hydrated. Consider using a stool softener. Be sure to tell your doctor about this. ...Read more
Is this a sign of a damaged vagus nerve? Every day before I have a bowel movement, I feel hyper stimulation in my intestines & it causes me to vomit!!
Vagotomy # effects: Vagotomy (cutting of the vagus nerve) is a now-obsolete therapy that was performed for peptic ulcer disease. Vagotomy is currently being researched as a less invasive alternative weight-loss procedure to gastric bypass surgery. the procedure curbs the feeling of hunger and is sometimes performed in conjunction with putting bands on patients' stomachs, resulting in average weight loss of 43% at. ...Read more
Seizure treatment: Vns is an fda-approved treatment for patients with refractory partial epilepsy (over age 12). It is a matchbook-sized device implanted under the skin in the upper left chest with a wire that connects to the left vagus nerve (in the neck). It is programmed by your neurologist to provide electrical stimulation for 30 seconds at 5 minute intervals. It can be a very effective treatment. ...Read more
Not a MOA: Hydralazine is a direct smooth muscle relaxer based on its intracellular action on Calcium. In situ, it does not appear to have a direct effect on the vagus nerve, but rather may have an effect on the sinoatrial node and a reflex response (increased heart rate) due to the decreased blood pressure (baroreceptor response). ...Read more
Hydralazine: It relaxes vascular smooth muscles, resulting in dilation of arteries & arterioles (small vessels). ...Read more
Please clarify: Frankly, I have no idea what your post means. The vagus nerve is PART of the nervous system. It's part of the parasympathetic nervous system. Maybe if you posted what led you to ask the question I could figure out what you mean because right now I haven't got a clue. It's like asking, "Which part of the car is control by 75% of the windshield? " ...Read more
Why do you ask?: Where did you get idea that your vagus nerve is damaged? Vagal input on the right affects the heart rate, and on left predominantly, the other internal organs within the thorax and abdomen. Vagal function can be tested, but I have NO clue as to why you are asking your question. ...Read more
Vagal Disorders vary: Neuralgia, respiratory and vocal problems, problems swallowing, stomach problems [gastroparesis], vasovagal reflex induced fainting, heart arrhythmias, and urinary problems. Patients with anxiety, depression, or who lose consciousness during complex partial seizures or generalized seizures, and whose seizures are not being controlled by medication, may benefit from vagal nerve stimulation. ...Read more
