What is a vagel or vagus nerve?

---

what does it do and can it cause chest pains. The pain felt like the heart was exploding. My 13 year old son had this pain and the ER doc could not find anything wrong with his heart and mentioned this nerve and said his potassium was low. They told me to follow up with his doc, have appt. on Thursday. Ohhh he also fainted during the chest pain episode if that helps any.
The vagus nerve helps to regulate the heart beat, control muscle movement, keep a person breathing, and to transmit a variety of chemicals through the body.
When the vagus nerve is stimulated, the response is often a reduction in heart-rate or breathing. In some cases, excessive stimulation can cause someone to have what is known as a vaso-vagal response, appearing to fall into a faint or coma because the heart rate and blood pressure drop so much.

If the ER doctor found no problem with your sons heart then i doubt he is in no imidiate danger. But its good that you have a follow up appointment with you doctor.

Take care and good luck!  (+ info)

anyone had trouble with vagus nerve stimulator?

---

my daughters unit failed after a year and a half, I really don't think it worked properly since she had it
she got her first unit in 2001. when the batteries failed she got a new one in nov. 07. this is the one that the unit failed, not the batteries.
I've had mine for about 9 years.I never had trouble with it and only needed 1 replacement after the first 5 years.Otherwise I'm glad I have it.Sounds like there was a faulty battery in the unit. Try going to www.cyberonics.com and tell them the problem.They might be able to give some insight on it.  (+ info)

lap nissen has anyone had dumping syndrome due to vagus nerve damaged during lap nissen?

---

has anyone been told before getting lap nissen that they could get dumping syndrome when vagus nerve is damaged during surgery?
31 and lots of problems,
Dumping syndrome is a recognized complication of various gastric surgical procedures, such as vagotomy, pyloroplasty, and gastrojejunostomy. However, it has not to date been reported following laparoscopic Nissen fundoplication in adults. You would be advised to speak to your, or the, doctor/surgeon involved in the surgery and, if necessary, obtain a second opinion. Most often, you'll find that dumping syndrome improves on its own without medical treatment or after adjusting your diet. In more-serious cases of dumping syndrome, you may need medications or surgery.

Could ECT or Vagus nerve stimulation be the answer?

---

I've had major depression for most of my life, I'm 32 years old. I tried pretty much all the meds available to no success. I'm tired of living this way. Does anybody have experience with ECT or Vagus nerve stimulation? Thanks
With regard to electroconvulsive therapy, this treatment is controversial, and just this month the person considered the leading expert and proponent of ECT (Harold Sackeim) admitted that ECT routinely causes potentially permanent amnesia and cognitive dysfunction (problems thinking), after preaching for 25 years that it did not, and the American Psychiatric Association adopted his position that it did not cause brain damage. This new study published this month was actually the FIRST large-scale study (believe it or not) to even check for peristent cognitive dysfunction after ECT. His results show, albeit indirectly, that ECT may cause brain damage that may be irreversible in some people. And his study only checked simple measures of cognitive function. It didn't delve at all into higher level human thinking, like the ability to philosophize, conceptualize, integrate knowledge, write a scholarly essay, etc. With that said, some people who've had ECT do not feel damaged by it other than some mild memory loss around the time of the treatment and consider it a life saver. It's possible your psychiatrist is not even aware of this study by Harold Sackeim, because it's published just this month. If you want a copy of this study, just email me and I'll send you a copy of it to give to your doctor. You can visit zaprap.org forums where people discuss their experiences with ECT. Most of the people there, however, are going to be the ones that complain that they have permanent cognitive dysfunction and problems processing and remembering information. The people who don't believe they were damaged by ECT don't post here often.

With regard to vagus nerve stimulation, the evidence for its benefits for depression have been disappointing. As noted in a recent review of the evidence for vagus nerve stimulation, " "a lack of Class I evidence of efficacy in treating depression is currently slowing down adoption by psychiatrists."
Study reference:
["Vagus nerve stimulation for the treatment of depression and other neuropsychiatric disorders." Expert Rev Neurother. 2007 Jan;7(1):63-74. George MS, Nahas Z, Borckardt JJ, Anderson B, Burns C, Kose S, Short EB.]

A minimum of 40% (some researchers say half or more) of depressed patients fail to respond to standard anti-depressants, and this is often after only trying several of them. And when they do work, data from published studies show it can take up to six weeks to begin working, which is a long wait.

I don't know if you've tried it yet, but there is a newly approved transdermal anti-depressant called "Emsam". It is a patch you place on your body and change once daily at your convenience. The patch is like a little square of scotch tape, almost. Anyway, Emsam is different from other commonly prescribed anti-depressants in that it doesn't inhibit the reuptake of neurotransmitters serotonin or norepinephrine. Rather, it prevents the breakdown of different neurotransmitters by acting as an MAO inhibitor. One of the things that makes it different is that it will have a substantial effect on raising levels of "dopamine", while all the other commonly-prescribed anti-depressants do not really affect dopamine levels. (Wellbutrin may have a very small impact on dopamine levels, but mostly all of its action is on norepinephrine). And ironically, the most effective anti-depressant ever developed was Survector (amineptine). This was a specific dopamine reuptake inhibitor (SDRI). One study showed it was efficacious in up to 78% of depressed patients who tried it. It was only on the market for a short time in the U.S. before the FDA banned it. Apparently it was possible to get high on it if one overdosed, and could become addictive for this reason.

MAOI's (like Parnate and Nardil) are not new drugs, in fact they were around before the SSRI's. And the efficacy of MAOI's is superior to the SSRI's and SNRI's you've probably already tried. The reason they have been rarely prescribed prior to the approval of Emsam is that there is potentially a very serious reaction when standard MAOI's are taken with food containing substantial tyramine, like aged cheese, aged meats, soy sauce, and beer on tap. It can cause hypertensive crisis. The transdermal Emsam patch prevents the need for dietary restrictions at the standard dose of 6mg/24. Higher dose patches carry the warning for food interactions as a precaution, but 5 studies were done with the higher dose patches without dietary restrictions and no problems were reported with food interactions. Again, with Emsam you'd still have that six week wait to see if you fee any different. Given that you probably haven't tried a dopamine increasing agent yet, it might be worth a try. (Again, the piddily effect that Wellbutrin has on dopamine doesn't really count.)

As an interesting note about Emsam (generic name selegiline), this drug has been found to consistenly and significantly extend lifespan in healthy animals including rodents and dogs, by over 20%. In other words, it may have some anti-aging properties. It is also often referred to as being a neuroprotectant at lower dosages, while some other antidepressants may actually be neurotoxic, including several of the tricyclics. It also helps to lower levels of oxidative stress in the brain by boosting levels of natural antioxidant enzymes your body makes. In effect, there's some interesting evidence that this drug may do a number of positive things in humans and animals.

All in all, currently available anti-depressants are really unsatisfactory for millions of people and often have no effect on their depression. Some of the newer drugs under development are taking a different approach altogether, but most of these won't be available for years.


Getting back to anti-depressants, I can tell you that even if you did find a drug that helped to you some extent, you can easily defeat the action of the antidepressant by following an unhealthy lifestyle that's likely to lead to depression (example: staying in bed all day and not doing anything). So, you have to be willing to do your part regardless of the drug.

Finally, there's also a drug called Stablon that is only available from overseas, and acts as a serotonin reuptake accelerator rather than an inhibitor. Some of the recent research shows that it may work by increasing neural plasticity. Some people in the U.S. are importing the drug and using it, since its mode of action is unique. But again, many still do not respond to it.

You've probably also heard of seasonal affective disorder that can cause depression. The name can be misleading, because lots of people have this condition year round, it's simply much more common in the winter. It is caused from lack of adequate sunlight, and is treated with special lightboxes and/or spending more time in the sun where possible. Basically, certain wavelengths of light when entering the eyes stimulate the release or shut-off of certain hormones and possibly other chemicals in the body. Apparently, some people require very little sunlight, and others quite a bit more for this purpose.  (+ info)

does anyone out there know anything about vagus nerve stimulation as a treatment for chronic depression?

---

a relative of mine is being nursed in a psycho-geriatric ward for chronic depression and at times psychotic episodes. She has been in there now for 6 months and the doctors want to try electric shock treatment in 2 weeks if she does not respond to a higher dose of antidepressant in that time. I have heard of vagal nerve stimulation as a better treatment but she has a pacemaker in situ and I don't know if this would cancel out the possibility of VNS. Can any one help?

Have you ever wondered about the reason of our existence? Have you ever wondered why we die, and where we go after death? What will happen to us in the end? Have you ever asked yourself why God made the earth and all that is in it under man’s dominion? Why were the night and the day, and the sun and the moon created? What are we supposed to do during our lifetime? Were we created just to eat, drink, and enjoy ourselves before we die? As one poet put it:
“I do not know whence I have come.
I saw my feet walking on the road.
As they please I go and stop.
What am I doing here?
How did the road find me?
I do not know! I do not know! I do not know! ”

God has emphasized in many verses of the Qur’an that He did not create us without purpose. He said: “What! Do you think that I created you simply in jest? And that you would not be returned to Me?” (23:115) He also said: “What! Does man think that he will be left to roam at his will?” (75:36) In addition, He said: “Do people think that they will be left to say: “We believe,” and they will not be held accountable?” (29:2)
Indeed, God Has created human beings for a purpose and with a purpose: TO WORSHIP HIM ALONE (Monotheism). He said: “I have not created the Jinn and humankind except only to worship Me. I don't require provision or feeding from them. Surely Allah is the All-provider, the Possessor of all strength, the Firm.” (51:56-58) In fact, all prophets told their people to worship God alone (Monotheism) and shun worshipping His creation (Paganism). God said: “I assuredly sent among every people a messenger with the command: Worship Allah and avoid worshipping false gods.” (16:36)
Prophet Abraham, for example, believed in One God, who had no partner. Anyone who holds a different understanding of God than this has contradicted the religion of Abraham and follows falsehood. God says in the Qur’an: “Those who reject the religion of Abraham make fools of themselves.” (2:130)
Prophet Jesus was reported in the Gospels to have said: “It is written: ‘Worship the Lord your God and serve Him only’.” (Luke 4:8)
Prophet Jacob also said (in the Qur'an) to his people: “Indeed, those which you worship besides Allah are only names that you and your forefathers have established, for which Allah has sent down no authority. The command belongs only to Allah. He has commanded that you worship none but Him. That is the right religion, but most people do not understand.” (12:40)

God, the Most Compassionate, didn't leave man to go astray without an unadulterated reference. Indeed, He revealed the Qur’an and promised to preserve it as the final revelation for humankind for all times. It is the word of God which He revealed to Prophet Muhammad (mercy and peace of God be upon him) through the Angel Gabriel. It was revealed in parts over a period of 23 years. The Quran deals with the basis of creeds, morality, history of humanity, worship, knowledge, wisdom, God-man relationship, and human relationship in all aspects. Comprehensive teaching on which, can be built sound systems of social justice, economics, politics, legislation, jurisprudence, law and international relations, are important contents of the Quran. The Prophet Muhammad (mercy and peace of God be upon him) dictated the revelation to his companions who wrote it down during his lifetime on palm leaves, parchments, bones, flat stones, etc. In addition, the Qur'an was committed to heart by many of Prophet Muhammad's companions. One year after the death of Prophet Muhammad (mercy and peace of God be upon him), the first Caliph (Ruler), Abu-Bakr, instructed the Prophet’s companions to collect the whole Qur’an in one volume. The third Caliph, Uthman, prepared several copies from the original text and sent them to the major centers of Islamic Civilization. From that time onwards, more than 1400 years ago, the same Qur’anic text has been in use with the exact wording, order and language (Arabic). Not a single word from its 114 chapters has been changed since it was revealed. Indeed, God promised in the Qur’an to preserve it forever. He said: “Verily, I have sent down the Qur’an, and indeed, I will guard it from corruption.” (15:9). An essential point to understand about the Qur’an is that it is a miracle both in its revelation and content.
I advise you to see the following links which show the evidence that the Holy Qur’an is a miracle.

www.miraclesofthequran.com

At the time of the revelation and since, there have been those who have denied the divine and miraculous nature of the Qur’an saying that Muhammad (mercy and peace of God be upon him) was either taught by others or that he wrote it by himself! In order to counteract this claim, God lays down a challenge to the whole of humankind saying: “ If you are in doubt concerning what I have revealed to My slave (Muhammad), then produce one chapter like it and you may call on your helpers beside Allah, if you are truthful.” (2:23) .These are from the prophecies which the Qur’an foretold as no one from the time of the Prophet (mercy and peace of God be upon him) until this day has been able to produce the like of one chapter or even a verse of the Qur’an.

Real happiness and peace can be ONLY found in submitting to the commands of the Creator and the Sustainer of this world. God has said in the Qur’an: (Truly, in remembering God do hearts find rest.)
(Qur’an, 13:28)

On the other hand, the one who turns away from the Qur’an will have a life of hardship in this world. God has said:
(But whoever turns away from the Qur’an, he will have a hard life, and We will raise him up blind on the Day of Judgment.) (Qur’an, 20:124)
This may explain why some people commit suicide while they enjoy the material comfort money can buy. For example, look at Cat Stevens (now Yusuf Islam), formerly a famous pop singer who used to earn sometimes more than $150,000 a night. After he converted to Islam, he found true happiness and peace, which he had not found in material success.

Vagus nerve and blood pressure?

---

My blood pressure drops suddenly at times as low as 70 over 45. This leaves me very dizzy. stange feelings in my arms and hands (like numbness). This usually happens when stopping strenous work, but also happens when just sitting around. My vision is also affected as everything gets very bright (white outs) and I am unable to read or make out figures. My GP thinks it is most likely the vagus nerve and I have a followup with the heart dr. soon. All tests on my heart including a cath have been great. Any of these symtoms relate to the vagus nerve? Thinks the stimulator would help?
There is a medical condition called Neurocardiogenic Syncope. It has something to do with the vagus nerve. Causes blood pressure problems and fainting. I have this condition and was diagnosed with a Tilt Table Test. Ask your dr. about it. There are several with this condition. There are support groups out there. Google and read about. It can be a life changing condition. Good Luck  (+ info)

Is VNS (vagus nerve stimul.) therapy more effective than pharmaceuticals for long-term treatment of depression?

---

made by Cyberonics of Houston, TX; surgically implanted, at total overall cost of $25,000 / patient.
the irony is the best treatment we know is placebo effect. truth is we don't know how vns works and we think we know how drugs work but the funny thing is both work in the exact opposite way as placebo yet you get the same result.
credit to Mopar Muscle Gal for reminding me. keep in mind that surgery always has risks. any time you go under the knife there is a chance you won't wake up. (a small one) so wiegh that in as well.  (+ info)
