Test For Vagus Nerve Damage
Test CN IX and X:
Neurologic exam for cranial nerves ix and x is performed simultaneously. We are looking for the soft palate elevation and gag reflex. Introduce tongue depressor in the back of the throat touching lightly the roof of the mouth.
Abnormality - asymmetrical
exam of localization - brain stem
mri to rule out pathology. ...Read more
A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more
UNUSUAL: Lesions in the lower brainstem, medulla oblongata are rather rare, but if they do occur, one might encounter problems with speech, such as a dysphonia, or a strained speech pattern. If there is widespread inflammation, also involving glossopharyngeal nerve, might see dysphagia, or swallowing problems. Likely the internal organs such as heart, lungs, GI tract would not be involved. ...Read more
Is vagus nerve damage repairable? Or, will the person have to deal with the issues for the rest of their life?
Vagus nerve: Helps lower heart rate so damage to it would lead potentially to higher heart rates and may exacerbate arrythmias. While generally not curable, arrythmias are treatable. ...Read more
What would the Symptoms of vagus nerve damage be like due to MS? Also where would they be found on an MRI? Would the lesions be in the c spine?
Alter body functions: Controlled (heart, lungs, digestive tract & other organs within chest & abdomen) by 2-way communication via the vagus nerve, the 10th of the cranial (ones which do not go through the spinal cord, thus not within the spinal cord; C-spine vertebra) nerves. Research vagus anatomy&physiology on Google. MRI best for soft tissue yet reveals very little of the fantastic complexity within what is imaged. ...Read more
My sister had gall bladder removed &has now developed severe gastroparesis. If b/c vagus nerve damage caused, can anything be done to reverse?
Massage no/ neck yes: Masage therapists are trained to avoid damage. With a neckinjury aproper evaluation is required. ...Read more
Can a tummy tuck damage the vagus nerve? And is vagus nerve damage repairable? Temporary? Permanent? How is it diagnosed?
Special Blood Test: Unfortunately, there is no 100% diagnostic test to confirm vagal nerve injury. Gastric emptying studies are often ordered but are notoriously unreliable. The best test is measurement of pancreatic polypeptide (pp) after Insulin administration. Normal secretion of pp is mediated by the vagus nerve in response to low blood sugar. If the vagus is injured, the pp level remains low after insulin. ...Read more
I developed anxiety and PVC'S after fundoplication. Vagus nerve damage? I was fine before surgey!!
Yes, it is possible: Damage to the vagus nerve is a known risk of fundoplication. How often this occurs has been investigated but has not been determined. Because increased tone of the vagus nerve can suppress PVC's, it is a reasonable possibility that new onset PVC's after fundoplication could result from damage to vagus nerve during the surgery. ...Read more
Can degeneration of the C5-C6 vertebra cause episodic syncope due to vagus nerve damage or entrapment?
No but VBI might: VertebroBasilar Insufficiency (VBI) - The vertebral arteries run up the back of the neck thru tunnels (foramen) in the vertebrae (bones of spine). Some neck maneuvers can compress the artery where it passes thru the foramen. While not usually syncope, this can cause vertigo & drop attacks via buckling of the knees usually in older folks with degenerative spinal problems. Aka beauty parlor syndrome. ...Read more
Could there be any connection between vagus nerve damage and burning/pins and needles feeling in face (around mouth and nose/lower forehead area)?
Not really: The short answer is "no." the sensory function of the vagus nerve has no relationship to facial or oral structures. The closest that the vagus nerve comes to any function in that region of the body would have to do mainly with the cough reflex. Trigeminal nerve dysfunction more likely causing symptoms you mentioned. I notice that gbs is listed under "conditions."is that currently or in the past? ...Read more
What is the vagus nerve or 'mini brain' and what are some tests I can get to see if mine is malfunctioning?
1st, take your pulse: The vagus nerve is a nerve that goes directly from the brain to various organs to run normal activities like regulation of the gut activity, heart rate and gland secretion. Irritation of the nerve often causes a decline in pulse rate (and lower blood pressure, dizziness and /or fainting). ...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
A bright 20yr old with 8autoimmune dx, 2 syndromes.11dr. Over 2yrs countless test, restricted diet, etc. She is having short lock in episodes. Vagus nerve?
Too complex: Too little information, can't give you a meaningful response. ...Read more
Can my vagus nerve be the cause of my anxiety? I had fundoplication and developed anxiety thereafter all heart tests are ok
One of the few times: In medicine that I believe I can say with 100% unequivocal certainty that NO- your vagus nerve cannot be the cause of yours OR ANYBODY's anxiety. That's because a single CRANIAL NERVE is incapable of causing the generation of a sentiment which is the conglomeration and coalescing of multiple intricate and personality specific attributes. ...Read more
Is the vagus nerve seen on a cervical spine MRI test? If so, if there is an issue with it, how can docs tell on the test?
All heart tests ok. Developed anxiety after fundoplication, heart racing always after eating. Blood work normal. Vagus nerve?
Symptoms: The vagus nerve controls heart rate blood pressure and other automatic functions of stomach, bowel, bladder. Vaso-vagal syncope is common with sudden pale, light-headed and faint. Stress, shock, donating blood etc can cause this reaction. Rubbing the neck may induce reaction. Heart rate studies may suggest a problem. ...Read more
What are the methods for diagnosing/ locating damage to vagus nerve? Can it be repaired/ reactivated?
The vagus="the wandering nerve is one of two vagus
nerves that are left anterior and right posterior along the esophagus in the chest to the stomach.
If one is damaged there may be no signs.
If both are damaged or surgically divided there are changes in gastric -stomach acid production and motility.
But if cut high in the neck the recurrent laryngeal -voice nerves will be affected. ...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
Neuropraxia is defined as a temporary loss of function of the nerve. Some nerves are purely sensory while others carry both sensory and motor fibers. Traumatic contusion injuries to nerves or nerve compressions can cause Neuropraxia. Sensory nerves like sural nerve in the leg or mixed sensory and motor nerves like the median and ulnar nerves in the forearm & hand ...Read more
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
