Is msg bad because it actually interacts with your brain and nerves as a chemical transmitter, or is that a myth?

Is msg bad because it actually interacts with your brain and nerves as a chemical transmitter, or is that a myth?

Glutamate: The glutamate part of monosodium glutamate (msg) is a chemical that excites brain cells by interacting with receptors as a neurotransmitter. Too much excitement might damage brain cells. It is not clear how much msg gets into the brain, but it does cause some people headaches and other symptoms. ...Read more

Nerve (Definition)

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

Does folate (folic acid) deficiency anemia affect the brain and nerves?

Does folate (folic acid) deficiency anemia affect the brain and nerves?

Yes: Folate (folic acid) is needed for maintenance and repair of myelin, the covering of larger/faster nerve fibers. Deficiency in utero results in birth defects of the neural cord, low birth weight or prematurity. Deficiency will slow growth in children. Peripheral neuropathy results in adults. Deficiency is reversible if treated early enough. Nerves suffer from folate (folic acid) deficiency itself more than from anemia. ...Read more

Can Post Viral Syndrome following shingles cause body wide neurological issues? I am a 36 year old man with a normal brain MRI worried about MS.

Can Post Viral Syndrome following shingles cause body wide neurological issues? I am a 36 year old man with a normal brain MRI worried about MS.

While there have..: ...probably been cases where this sequence of events was thought to be associated, this is not a common identifiable pathway for MS to develop. Millions of cases of post-viral syndrome or shingles occur without resulting in MS. The normal brain MRI is reassuring. I would definitely not worry about this. Continue to work with your doctor for diagnosis and treatment. Good wishes:) ...Read more

Whole body MS symptoms: neuropathy, trigeminal pain, parathesia, etc. Brain MRI normal. I had shingles not long before this. Could it be post viral?

Response: First, doubt we can blame the shingles. But do you have evolution of a peripheral neuropathy, or even MS which has not been demonstrated.. Second, get EMG testing over the limbs. Third, get MRI of cervical spines. If this all proves fruitless, we would be happy to schedule Concierge visit online. ...Read more

I had shingles and doc did 1 week acyclovir 400mg 5x/day. There are still red bumps. Is there still virus, and can it still infect the heart/brain?

I had shingles and doc did 1 week acyclovir 400mg 5x/day.  There are still red bumps.  Is there still virus, and can it still infect the heart/brain?

Sounds OK: If your rash is improving, the acyclovir is working; it takes a couple weeks for complete clearing of shingles. However, if any new bumps are appearing, ask your doc about continuing acyclovir a few more days. Even without treatment, there is no risk of brain or heart infection. Varicella zoster virus (VZV), the cause of chickenpox and shingles, doesn't affect the heart or brain. ...Read more

I had shingles on the back of my head and then 2 weeks later, i spent 2 weeks in intensive care with cerebral venous sinus thrombosis.  Connection?

Hard to say: There may in fact be an underlying causation creating susceptibility to both, and one might consider an immune mediated process or even, something like one of the antiphospholipid antibody syndromes. However, the shingles did not cause the venous thrombosis. Yet, the two items signal some general pathology, and worthwhile to fully evaluate. ...Read more

Can shingles occur on cranial nerves without a single rash or symptom and cause post-herpetic neuralgias silently?

Can shingles occur on cranial nerves without a single rash or symptom and cause post-herpetic neuralgias silently?

Unlikely: Some form of rash or sores should be present for shingles. You may have trigeminal neuralgia. This is a pain condition that usually presents with brief episodes of pain along the course of the Trigeminal Nerve or one its branches or divisions. It can be very painful-similar to a post-herpetic neuralgia. ...Read more

Can you get shingles in the cranial ganglia and then have neuralgias in all of the nerves? would you show a rash in your face is it was the case?

Can you get shingles in the cranial ganglia and then have neuralgias in all of the nerves? would you show a rash in your face is it was the case?

Nope: Herpes zoster (shingles) can originate from any nerve, including a cranial nerve, causing an outbreak of the scalp, face, etc. Sometimes shingles is followed by ongoing pain due to post-herpetic neuropathy (PHN) from the involved nerve. It does not cause neuralgia in any other nerves. Without a localized skin rash, shingles almost certainly isn't the cause of any symtoms you have. ...Read more

Can a reactivation of shingles last for a lifetime, and the virus jumps from nerve to nerve slowly? or it always lasts 2-4 weeks?

PHN?: Second outbreaks can occur, but each outbreak generally lasts a maximum of 3-4 weeks. There is no such thing as a lifelong shingles outbreak or "jumping from nerve to nerve". However, post-herpetic neuralgia, or PHN -- nerve pain following a shingles outbreak -- can persist for months or years. Discuss with your doctor if you have continuing pain in an area of previous shingles. ...Read more
