What are nerve conditions?
The peripheral nervous system transmits sensory information between the muscles, tissues and nerves in the rest of the body to the brain. When any of these connections are disrupted, nerve symptoms occur.
What are the symptoms of nerve disorders?
The symptoms of nerve conditions are diverse because the nervous system governs or participates in a number of functions as well as body systems, including control of body temperature, blood pressure, muscles, digestion and appetite, movement, and sight.
What are the risk factors for nerve conditions?
A number of factors increase the risk of developing nerve conditions. Not all people with risk factors will get nerve conditions. Risk factors for nerve conditions vary according to the type of condition . Some risk factors for nerve damage include:
What are the potential complications of nerve conditions?
Because nerve conditions can be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce your risk of potential complications including:
What causes nerve pain?
Nerve symptoms can also stem from autoimmune diseases such as lupus erythematosus or Guillain-Barré syndrome or viruses such as the human immunodeficiency virus ( HIV ), Epstein-Barr, or varicella-zoster.
How to treat nerve pain?
The goals of therapy are to manage the symptoms, including pain, and to treat the underlying condition, if possible. Therapies include medication, surgery, and injections of local anesthetics, as well as complementary treatments such as biofeedback, acupuncture and massage.
What is referred pain?
In referred pain, a more complex condition, the sensation of pain is felt in a different part of your body than where the injury or illness actually occurred. Referred pain is the most difficult to diagnose and treat. Nerve conditions can arise from one nerve or many.
What is the nervous system?
nervous systemthe organ system that, along with the endocrine system, correlates the adjustments and reactions of an organism to internal and environmental conditions. It is composed of the brain, spinal cord, and nerves, which act together to serve as the communicating and coordinating system of the body, carrying information to the brain and relaying instructions from the brain. The system has two main divisions: the central nervous system,composed of the brain and spinal cord; and the peripheral nervous system,which is subdivided into the voluntaryand autonomic nervous systems. (See color plates.)
What is the basic unit of the nervous system?
The Nerve Cell. The basic unit of the nervous system is the nerve cell, or neuron. This highly specialized cell has many fibers extending from it which carry messages in the form of electrical charges and chemical changes. The fibers of some cells are only a centimeter or less long (a fraction of an inch), but those of others (for example, the sciatic nerve) may extend for half a meter to one meter (18 inches to more than 3 feet). These fibers reach into muscles and organs throughout the body and to the ends of the fingers and toes, and they cluster by the thousands in certain areas of the skin no larger than the head of a pin. The nerve fibers come together from the extremities of the body and gather into cables running to and from the brain. Along the length of the spinal cord are a number of junctions where impulses or messages are sorted or relayed to higher centers. The fibers of connecting nerve cells do not touch each other. Impulses are relayed from one to another by chemical means across the gap or synapse between them. In most cases an impulse must cross more than one synapse to cause the desired action.
What are the two systems of the autonomic nervous system?
The autonomic system is further specialized into two subsidiary systems: the sympatheticand the parasympathetic. The control centers of these systems lie in the hypothalamus. The sympathetic and parasympathetic nervous systems are continuously operative, functioning to adjust body processes to external and internal demands. (See also Plates.)
How does the sympathetic nervous system work?
This is done by the discharge of stimulating secretions at nerve junctions. These secretions, along with epinephrine discharged into the blood by the adrenal medulla, help start muscle action quickly. Glucose is released from the liver into the blood and thus is made available to all the body's muscles as a source of quick energy. The rates of heart and lung action increase, digestive activity slows down, blood vessels constrict, and sweating begins so that the body will be kept cool while under stress. Thus the body is prepared for an extraordinary effort.
Which system controls the body's motor and sensory nerves?
It is divided into two specialized subsystems. The autonomic nervous systemoperates without conscious control as the caretaker of the body. The voluntary nervous system,which includes both motor and sensory nerves, controls the muscles and carries information to the brain.
Where do mononuclear phagocytes come from?
mononuclear phagocyte systemthe group of highly phagocytic cells that have a common origin from stem cells of the bone marrow and develop circulating monocytes and tissue macrophages, which develop from monocytes that have migrated to connective tissue of the liver (kupffer's cells), lung, spleen, and lymph nodes. The term has been proposed to replace reticuloendothelial system, which includes some cells of different origin and does not include all macrophages.
What is it called when a nerve is only one nerve?
Autonomic nerves control bodily systems like the gastrointestinal and urinary systems. If only a single nerve is affected, it is called mononeuropathy. If several nerves are affected, it is called polyneuropathy.
What Is Neuropathy?
Neuropathy is the medical term for a condition in which there are problems with nerves in the body; either they have been damaged or are affected by a disease . Usually, neuropathy affects the peripheral nervous system rather than the central nervous system (brain and spine). As of December 2014, the National Institutes of Health estimated that peripheral neuropathy affects about 20 million people in the U.S.
What causes neuropathy in the hands and feet?
The most common cause of peripheral neuropathy is diabetes; prolonged high blood sugar eventually damages the walls of blood vessels, and the small vessels in the hands and feet show signs of damage first. Other possible causes of neuropathy include: Vitamin deficiencies (especially vitamin B12) Medications. Toxins.
What are the different types of nerves?
In the peripheral nervous system, there are three primary types of nerves: 1 Sensory nerves control the senses and the body's interpretation of different sensations. 2 Motor nerves control muscle movement and power. 3 Autonomic nerves control bodily systems like the gastrointestinal and urinary systems.
What is neuropathy surgery?
If neuropathy is due to pressure on the nerve (s), surgery may be necessary to remove the pressure and restore functioning. Lesson Summary. Neuropathy is a broad term used to describe nerve damage or disease. It can affect sensory, motor, or autonomic nerves.
What are the three main types of nerves?
In the peripheral nervous system, there are three primary types of nerves: Sensory nerves control the senses and the body's interpretation of different sensations. Motor nerves control muscle movement and power. Autonomic nerves control bodily systems like the gastrointestinal and urinary systems. If only a single nerve is affected, it is called ...
How can a physician assess nerve function?
The physician can also assess nerve functioning by performing nerve conduction studies . Electromyography is a procedure that tests the electrical activity of muscles. Nerve biopsies can also assess the density of nerves in a particular area. When treating neuropathy, there are three main goals:
What is neuropathy in the brain?
Neuropathy results when nerve cells, called neurons, are damaged or destroyed. This disrupts the way the neurons communicate with each other and with the brain.
How common is neuropathy?
Neuropathy is very common. It is estimated that about 25% to 30% of Americans will be affected by neuropathy. The condition affects people of all ages; however, older people are at increased risk. About 8% of adults over 65 years of age report some degree of neuropathy.
What causes numbness in the hands and feet?
Neuropathy is damage or dysfunction of one or more nerves that typically results in numbness, tingling, muscle weakness and pain in the affected area. Neuropathies frequently start in your hands and feet, but other parts of your body can be affected too.
How does neuropathy affect the brain?
This disrupts the way the neurons communicate with each other and with the brain. Neuropathy can affect one nerve ( mononeuropathy) or nerve type, a combination of nerves in a limited area (multifocal neuropathy) or many peripheral nerves throughout the body (polyneuropathy).
How many types of neuropathy are there?
There are over 100 types of neuropathies and each type can develop differently. The way your condition progresses and how quickly your symptoms start can vary greatly depending on the type of nerve or nerves damaged, and the underlying cause of the condition. There are many causes of neuropathy.
How long does it take for a neuropathy to develop?
Some peripheral neuropathies develop slowly – over months to years – while others develop more rapidly and continue to get worse. There are over 100 types of neuropathies and each type can develop differently. The way your condition progresses and how quickly your symptoms start can vary greatly depending on the type of nerve or nerves damaged, and the underlying cause of the condition.
How long does it take to recover from neuropathy?
Recovery, if it’s possible, usually takes a very long time -- from months to even years. Some people live with a degree of neuropathy for the rest of their lives.
Overview
The demyelinating form of Guillain-Barre syndrome destroys the protective covering of the peripheral nerves (myelin sheath), preventing the nerves from transmitting signals to the brain.
Symptoms
Guillain-Barre syndrome often begins with tingling and weakness starting in your feet and legs and spreading to your upper body and arms. In about 10% of people with the disorder, symptoms begin in the arms or face. As Guillain-Barre syndrome progresses, muscle weakness can evolve into paralysis.
Causes
The exact cause of Guillain-Barre syndrome isn't known. The disorder usually appears days or weeks after a respiratory or digestive tract infection. Rarely, recent surgery or vaccination can trigger Guillain-Barre syndrome. Recently, there have been cases reported following infection with the Zika virus.
Risk factors
Guillain-Barre syndrome can affect all age groups. But your risk increases as you age. It's also more common in males than females.
Complications
Guillain-Barre syndrome affects your nerves. Because nerves control your movements and body functions, people with Guillain-Barre may experience:
What is motor disability?
motor disability, with decreased ability to move affected body part
What is Reflex Sympathetic Dystrophy (RSD) Syndrome?
RSD is an older term used to describe one form of Complex Regional Pain Syndrome (CRPS). Both RSD and CRPS are chronic conditions characterized by severe burning pain, most often affecting one of the extremities (arms, legs, hands, or feet). There are often pathological changes in bone and skin, excessive sweating, tissue swelling and extreme sensitivity to touch, known as allodynia.
Is there a cure?
There's no cure at this time, but research continues. Advances have resulted in some new and effective treatments. Some patients may experience a remission of symptoms.
