Is Sciatica Usually A Problem In The Central Or Peripheral Nervous Systems
Movement Disorder: Rls is classified as a movement disorder and we believe it arises primarily in the brain. Some people have secondary RLS associated with neuropathy, herniated discs. But the muscles of the legs are generally a "problem". If you have rls, consult with a physician to see if it truly is or a symptom of another problem. ...Read moreSee 1 more doctor answer
Do most neurological disorders usually affect the central nervous system or the peripheral nervous system?
Not sure: I can't tell which but it can be due to low iron levels and it not this it responsed to Dopamine agonists like Requip (ropinirole) or sinemet implying a nervous system problem. Some people do better with anticonvulsant meds like Neurontin or Klonopin which may have some muscle relaxant effects. So it may have multiple causes. ...Read moreSee 1 more doctor answer
There isn't just one: There may not be just one nerve that brings heart pain to the brain. This is why people describe their heart attack symptoms so differently. Some people get nausea, sweating and a sense of "just not feeling right, " while others get the more classic chest and arm pain. Others may get extreme heaviness in the chest and shortness of breath. Thi suggests that different nerve pathways can be involved. ...Read moreSee 1 more doctor answer
Is it the central or peripheral nervous system problem if you get back pain with sensations going down a leg?
Describing sciatica: Peripheral nerve compression.As the nerves leave the spinal column the "disc", a tough, fibrous, shock absorber that is between the vertebral bones can extrude and press on the nerve in a few places.This is usually "self-limited" meaning it goes away over time with stretching, nsaid's like ibuprofen, and traction(gravity boots).Usually no images(x-ray, ct, mri) needed unless weakness, bladder, bowel, chang. ...Read moreSee 1 more doctor answer
Does serotonin cause muscular rigidity via its effects in the central nervous system or by binding to peripheral 5-ht receptors in the body?
Centrally: Overstimulation of primarily the 5-ht2a receptors seems the leading hypothesis currently. ...Read more
Could the immune system attack nerve cells and kill the nerves throughout the body? Is this rare? Whats this diagnosed as.
Nerve cells: Yes, the nervous system can be the target of an inflammatory response by the immune system. If such attack occurs in the brain or spinal cord it is called cerebritis or gliosis and myelitis. Multiple sclerosis is an example of this phenomenon. If the attack occurs in the nerves of te arms or legs then it is called neuropathy. Certain clinical syndromes are recognized depending the progression and distribution. ...Read more
What is a recessive genetic disease that results in the deterioration of the central nervous system in infancy?
CNS deterioration: Leukoencephalopathy.Get a more detailed answer ›
Anatomical terms: Brain, spinal cord, and cranial nerves, especially optic nerves, all start within the central system. Once outside the spinal canal these nerves are now called peripheral nerves and connect to muscle to cause contraction, and return to spinal cord, sensory nerves, to report peripheral sensations from outer world. ...Read more
What if the cause of the neuropathy (i.e peripheral neuropathy) is injury/trauma can the problem be resolved? I.e nerve damage. e.g in the penis.
If fibromyalgia is believed to be caused by the central nervous system why can't it be fixed with some kind of surgery?
What to fix?: The problem seems to be faulty signalling from the muscles and organs back to the brain. Pain signals that are sent are not necessarily sent in response to an actual painful stimulus. Many factors - stress, immune system, hormones, mood - all seem to affect the pain signals in FMS patients. Since we don't understand how all this happens yet we don't know exactly what to fix yet! ...Read moreSee 1 more doctor answer

Does the autonomic nervous systems (ANS) repair or heal itself particularly in cases of autonomic dysfunction (dysautonomia)? If not, what are some treatments for erectile disfunction caused by dysautonomia?
Multiple submissions: Your question has already been answered on this site. I suggest a formal physical examination and if autonomic dysfunction see a neurologist. ED requires further investigation and evaluation. ...Read more
OK: Central nervous system - brain & spinal cord Peripheral nervous system - all the nerves that come out from the brain and spinal cord. Within the peripheral nervous system you have 'somatic' and 'visceral' nervous systems. Somatic refers to muscle, skeleton, skin. Visceral refers to internal organs. In a nutshell! ...Read more
Not really: There is some similarity but the brain is much more complex that the most powerful computer. Not only is it processing information at an enormous rate, but it is storing information with what appears to be almost unlimited size and is capable of modifying older stored information on the fly. ...Read more
Can a venous pathology or a venous clot cause a leg to feel colder or is temperature of the legs only related to issues in the arteries?
Inflammation of the central nervous system... Could it be possible that it is multiple sclerosis?
Broad term: Inflammation is part of the innate immune response following insults to the body which can spread into the central nervous system (cns). Inflammation within the CNS is part of the pathogenesis of the primary neurodegenerative diseases such as alzheimer's and parkinson's disease. And yes, it is considered to be a part of the way demyelination occurs in multiple sclerosis. I hope this helps. ...Read more
