FDA Approves Abbott’s Spinal Cord Stimulation for People Living with Painful Diabetic Peripheral Neuropathy
The new indication for Abbott’s Proclaim™ XR SCS system provides a non-medication option for people with painful diabetic peripheral neuropathy Spinal cord stimulation is proven to be more effective than conventional medical management in the treatment of chronic pain 1,2
, / PRNewswire / – Abbott (NYSE: ABT) announced today that the U.S. Food and Drug Administration (FDA) has approved its Proclaim™ XR spinal cord stimulation (SCS) system to treat painful diabetic peripheral neuropathy (DPN), a debilitating complication of diabetes.
The Proclaim XR SCS system can provide relief to DPN patients in need of alternatives to traditional treatment approaches, such as oral medication. People who receive therapy from the Proclaim XR SCS system will also be able to use Abbott’s NeuroSphere™ Virtual Clinic, a connected care app that allows people to communicate with a physician and receive treatment adjustments remotely.
Roughly 34.2 million Americans, or 10.5% of the U.S. population, have diabetes.3 Diabetic neuropathy, one of the complications of diabetes, is a type of damage seen predominately in nerves running to the feet.4 During their lifetime, approximately 50% of adults with diabetes will develop peripheral neuropathy, which may include symptoms such as pain and numbness in the legs, feet and hands.5 Currently, there are no disease modifying treatments for DPN, only symptom management and behavioral modifications to mitigate further nerve damage that can result from high blood sugar (glucose) levels.6 Spinal cord stimulation is a non-opioid approach that has been used for more than 50 years to help manage chronic pain and is proven to be more effective than conventional medical management in the treatment of this type of chronic pain.1,2 As a global leader in diabetes care, Abbott is committed to bringing life-changing solutions, including diagnostics, nutritionals, medicines and medical devices such as spinal cord stimulation to help better the lives of people living with diabetes.
Approved for the treatment of chronic pain in 2019, the Proclaim XR SCS system now offers DPN patients relief from chronic pain by delivering traditional “tingling” tonic stimulation.** People experiencing DPN can engage with their healthcare provider to be referred to a pain management specialist or spine surgeon to discuss the details of this treatment to determine the best course of care.
“Diabetic peripheral neuropathy has long plagued people affected by type 1 and type 2 diabetes, often adding another area of disease management on top of their ongoing monitoring of their glucose levels to manage this challenging disease,” said Jason E.
Pope, MD, DABPM, FIPP, president of Evolve Restorative Center in Santa Rosa, Calif. “Abbott’s Proclaim XR spinal cord stimulation system provides patients with painful diabetic peripheral neuropathy the opportunity to obtain a better quality of life while more seamlessly fitting into their current lifestyles.” Following a successful minimally invasive trial and undergoing an implant with the Proclaim XR SCS device, patients will have the ability to control their therapy through an Apple device.
The device can also be programmed using the company’s proprietary NeuroSphere Virtual Clinic technology, a first-of-its-kind remote patient care technology in U.S. that allows users to communicate with physicians, ensure proper settings and functionality, and receive new treatment settings/adjustments remotely, as needed.* “As a leader in diabetes care, Abbott is intimately familiar with the challenges people with diabetes encounter daily.
- This new indication for Proclaim XR will drive meaningful change in the treatment of pain associated with diabetic peripheral neuropathy and will be an important tool for physicians and patients in managing this debilitating condition,” said Pedro Malha, vice president, neuromodulation, Abbott.
- Anywhere with a cellular or Wi-Fi connection and sufficiently charged patient controller.
**Clarification: Abbott has updated the original release issued on Jan.26, 2023. The original release referenced incorrect settings used for diabetic peripheral neuropathy and has been updated to indicate the approval is for tonic stimulation mode only.

What is the newest medication for nerve pain?
FDA Approves NUCYNTA® ER (tapentadol) Extended-Release Oral Tablets for the Management of Neuropathic Pain Associated with Diabetic Peripheral Neuropathy | Johnson & Johnson.
Can diabetic nerve pain be stopped?
There is no cure for diabetes-related neuropathy. You can manage nerve pain with medication, exercise and proper nutrition.
What can I take naturally for diabetic nerve pain?
At-Home Treatments for Diabetic Neuropathy affects approximately 50% of individuals with, It develops from long-term elevated blood glucose levels that gradually cause nerve damage. Managing with proper medical care, blood sugar monitoring, and a healthy lifestyle is critical in preventing or slowing the progression of diabetic neuropathy.
- Although there is no known cure for diabetic neuropathy, treatment includes slowing the progression, relieving pain, managing complications, and restoring function.
- Eeping blood glucose levels within a healthy range is the most efficient way to slow the progression of diabetic neuropathy.
- Diabetic neuropathy can have a negative impact on mood, sleep, and quality of life.
In addition to conventional medical treatments for diabetic neuropathy, certain at-home treatments may provide pain relief and improve quality of life. At-home treatments for diabetic neuropathy include the following: Keeping blood sugar levels within a healthy range can slow the progression and ease the pain of diabetic neuropathy.
Maintaining a healthy body weightManaging stress levelsExercising 30 minutes per day, 5 days per weekEating more fruits, vegetables, low-fat dairy, and whole grainsEating moderate amounts of fish, poultry, nuts and beansLimiting red meatTaking prescribed medications as recommended by a health care provider
Over-the-counter pain relievers can ease pain caused by diabetic neuropathy. Examples include acetaminophen, aspirin, ibuprofen or naproxen. A physician should be consulted if any of these medications are taken on a regular basis, as prolonged use can cause serious health issues. Capsaicin cream can provide relief from the burning pain associated with diabetic neuropathy. Low doses of capsaicin cream can be purchased over-the-counter; however, if a higher dosage is needed, it must be prescribed by a physician.
Vitamin D can help protect against nerve pain. The skin produces this essential nutrient when exposed to sunlight. Low levels of vitamin D are associated with increased pain levels. Taking a vitamin D supplement once per week may reduce pain levels. Vitamin B complex may help reduce pain associated with diabetic neuropathy. Low levels of vitamin B12 increase the risk of nerve damage. Vitamin B6 helps the brain produce certain chemicals; low levels of these chemicals may increase pain levels.Most people get enough B vitamins via the foods they eat. A physician should be consulted prior to taking a vitamin B complex supplement to ensure it is recommended. Alpha-lipoic acid is a powerful antioxidant. It is naturally produced by the body in small amounts; however, supplementing the diet with alpha-lipoic acid can help regulate blood sugar levels, ease nerve pain, and prevent further nerve damage.
Warm baths help boost circulation and promote relaxation. A warm bath can provide instant pain relief. However, because diabetic neuropathy can lead to loss of sensation, so careful monitoring of the water temperature in the bath is advised. A warm foot bath with chamomile or nettle leaves can also ease pain.
Scissors, knives and other sharp tools in the home should have safety guards to prevent injury. The temperature of bath and sink water should be checked with a thermometer to ensure it is not too hot.Potholders and gloves should be used when handling hot items, especially when removing something from the oven.A cane or walker can help provide stability to reduce the risk of falling.Nightlights can help prevent trips and falls due to lack of proper lighting.Hands and feet should be properly covered when going outside in cold weather.Alcohol and smoking should be avoided. Tobacco decreases circulation in the feet, and alcohol increases nerve pain. Prolonged use of alcohol and tobacco can cause nerve damage.Added pressure on an area affected by diabetic neuropathy should be avoided (e.g., leaning on elbows, crossing the legs, etc.)Caffeine should be limited or avoided because it can interrupt proper, Sleep plays an essential role in pain management.
: At-Home Treatments for Diabetic Neuropathy
Has anyone recovered from neuropathy?
Treatments for Neuropathy – The peripheral nerves have a great ability to heal. Even though it may take months, recovery can occur. However, in some situations, symptoms of neuropathy may lessen but not completely go away. For example, nerve injury caused by radiation often does not recover well.
If it is related to nutritional deficiencies, supplements may help. If the neuropathy is related to a medical condition, such as diabetes or thyroid dysfunction, treating the condition can sometimes reverse the neuropathic symptoms. For neuropathy related to chemotherapy, most treatments are supportive and designed to improve symptoms and function. If problems develop during treatment and you continue to receive chemotherapy, the neuropathy can get worse. Clinical trials research shows promise in some treatments with medications that help peripheral nerves to heal and prevent the neuropathy associated with chemotherapy from occurring or being as severe.
How long is life expectancy after neuropathy?
Abstract – Introduction: We analyzed data from a prospective cohort of older primary care patients to determine whether the presence of peripheral neuropathy (PN) was associated with premature mortality and to investigate potential mechanisms. Methods: PN was defined as the presence of 1 or more bilateral lower extremity sensory deficits detectable by physical examination.
Mortality was determined from key contacts and Internet sources. Statistical models were used to evaluate the association between PN and mortality. Results: Bilateral lower extremity neurological deficits were common, reaching 54% in those 85 and older. PN was strongly associated with earlier mortality.
Mean survival time for those with PN was 10.8 years, compared with 13.9 years for subjects without PN. PN was also indirectly associated through impaired balance. Conclusions: In this relatively healthy cohort of older primary care patients, PN detectable by physical examination was extremely common and strongly associated with earlier mortality.
One possible mechanism involves loss of balance, though our data were insufficient to determine whether poor balance led to injurious falls or to less-specific declines in health. These findings may warrant further studies to determine the causes of age-associated PN and potential impact of early detection and balance improvement and other fall prevention strategies.

What pain killer is best for nerve pain?
Prescription medication side effects – According to Sharma, potential side effects of anticonvulsants include:
drowsiness (which usually improves as one adjusts to the dosing) dizziness nausea mood fluctuations blurry vision fluid retention or swelling in feet weight gain
Meanwhile, she continues, the possible side effects of both SNRIs and TCAs are very similar:
dry mouth constipation urine retention dizziness drowsiness vivid dreams changes in appetite
“For side effects that are difficult to tolerate, contact your medical team as soon as you can,” says Hascalovici. While certain medications effectively lower neuropathic pain, complementary approaches can also be taken. Hascalovici believes “a multidisciplinary, multimodal treatment approach that treats the body, the mind, and the social well-being of each patient is best.” For instance, “meditation or cognitive behavioral therapy ” can be helpful, he notes.
- Acupuncture is another potential option, with people with neuropathy in a small study reporting pain improvement following the treatment.
- It’s thought that transcutaneous electrical nerve stimulation machines may help lower nerve pain and are “sometimes recommended for diabetes-related neuropathies,” says Hascalovici.
However, scientific evidence to support their use is generally inconclusive. Finally, Khorassani notes that yoga may be beneficial, and research indicates it may aid in lowering cancer-related nerve pain. Nerve pain can occur because of various reasons and manifests in different forms, from tingling to stabbing sensations.
- There are numerous treatment options for neuropathic pain, including OTC, prescription medications, and nonpharmacological approaches.
- Some of the most commonly prescribed drugs for nerve pain are gabapentin, pregabalin, and duloxetine.
- However, these can lead to side effects such as drowsiness, nausea, dizziness, and dry mouth.
Whether the nerve pain will fully disappear depends on its cause and severity. And, as Hascalovici points out, “It’s helpful to realize there is no silver bullet treatment or one-size-fits-all therapeutic approach.”
What is the number one medicine for neuropathy?
Medications – Besides medications used to treat conditions associated with peripheral neuropathy, medications used to relieve peripheral neuropathy signs and symptoms include:
Pain relievers. Over-the-counter pain medications, such as nonsteroidal anti-inflammatory drugs, can relieve mild symptoms. For more-severe symptoms, your doctor might prescribe painkillers. Medications containing opioids, such as tramadol (Conzip, Ultram, others) or oxycodone (Oxycontin, Roxicodone, others), can lead to dependence and addiction, so these drugs generally are not prescribed unless all other treatments fail. Anti-seizure medications. Medications such as gabapentin (Gralise, Neurontin, Horizant) and pregabalin (Lyrica), developed to treat epilepsy, may relieve nerve pain. Side effects can include drowsiness and dizziness. Topical treatments. Capsaicin cream, which contains a substance found in hot peppers, can cause modest improvements in peripheral neuropathy symptoms. You might have skin burning and irritation where you apply the cream, but this usually lessens over time. Some people, however, can’t tolerate it. Lidocaine patches are another treatment you apply to your skin that might offer pain relief. Side effects can include drowsiness, dizziness and numbness at the site of the patch. Antidepressants. Certain tricyclic antidepressants, such as amitriptyline, doxepin (Silenor, Zonalon) and nortriptyline (Pamelor), have been found to help relieve pain by interfering with chemical processes in your brain and spinal cord that cause you to feel pain. The serotonin and norepinephrine reuptake inhibitor duloxetine (Cymbalta, Drizalma Sprinkle) and the extended-release antidepressants venlafaxine (Effexor XR) and desvenlafaxine (Pristiq) also might ease the pain of peripheral neuropathy caused by diabetes. Side effects of antidepressants may include dry mouth, nausea, drowsiness, dizziness, changes in appetite, weight gain and constipation.
What makes diabetic nerve pain worse?
High levels of cholesterol and triglycerides, as well as high blood pressure and obesity in general, are strongly linked with a higher overall risk of diabetic neuropathy and quickly worsening symptoms. All these factors are tied either directly or indirectly to what you eat.
Does magnesium help diabetic nerve pain?
Magnesium helps regulate blood sugar levels better, which can have a positive effect on controlling diabetes symptoms such as fatigue, vision problems, and other health complications. Additionally, magnesium acts as an anti-inflammatory agent for those who suffer from diabetic nerve pain.
How painful is diabetic nerve pain?
Abstract – Diabetes, a silent killer, is a leading cause of neuropathy. Around 50% of diabetic patients develop peripheral neuropathy in 25 years. Painful diabetic neuropathy manifests as burning, excruciating, stabbing or intractable type of pain or presents with tingling or numbness.
- The pathophysiology of this condition is due to primarily metabolic and vascular factors.
- There is increase in sorbitol and fructose, glycated endproducts, reactive oxygen species and activation of protein kinase C in the diabetic state.
- All these factors lead to direct damage to the nerves.
- The first step in the management of painful diabetic neuropathy is a tight glycaemic control.
Currently there is no drug which can halt or reverse the progression of the disease. Most of the therapies prevalent aim at providing symptomatic relief. Antidepressants like tricyclic antidepressants (TCAs) and selective norepinephrine reuptake inhibitors (SNRIs) have good efficacy in controlling the symptoms.
- Selective serotonin reuptake inhibitors have not shown the same consistent results.
- Anticonvulsants including pregabalin, gabapentin and lamotrigine have shown good results in the control of symptoms whereas same was not found with carbamazepine, oxcarbazepine and topiramate.
- Topical agents (capsaicin, topical nitrates and topical TCAs) and local anaesthetics have also been used with good results.
Use of opioids and non steroidal anti-inflammatory drugs although common but is not preferable. The newer therapies under studies are NMDA antagonists, aldose reductase inhibitors, neurotropic factors, vascular endothelial growth factor, Gamma linolenic acid, protein kinase C beta inhibitors, immune therapy, hyperbaric oxygen and alpha lipoic acid.
What is the end stage of neuropathy?
It indicates that the nerves are dying. While the relief may be nice, it also shows that much of the small nerve fibers have disintegrated. The larger fibers are now beginning to become permanently damaged, too. Your balance is likely affected by this, and you may find that it’s difficult to walk.
Can you live a healthy life with neuropathy?
Living with neuropathy – is the result of damage to nerve cells that send messages from the brain and spinal cord to the rest of the body. People with neuropathy experience abnormal sensations, such as tingling, numbness, burning, and pain, usually in the legs, feet, and hands, although it can occur anywhere in the body.
Is neuropathy for life?
Search for neurologists near you and schedule your next appointment today – May 7 to 13 is National Neuropathy Awareness Week. The week highlights the national effort to educate the public on neuropathy’s causes, treatments, and prevention strategies.
If you or someone you care for is living with neuropathy, the week presents an excellent opportunity to learn more about this condition and help others. What Is Neuropathy? Approximately 20 million Americans are living with peripheral neuropathy. While the term “neuropathy” simply means “nerve damage,” peripheral neuropathy is the impairment of the nerves in the body’s outer extremities – such as the hands and feet.
While the explanation for an individual’s neuropathy is sometimes unknown, a wide range of factors can cause it. Here are some causes of this chronic neurological disease.
Trauma from injury and repetitive stress is the most common cause, and medical treatments, like certain types of chemotherapy and surgeries, can damage nerves. Nearly 70 percent of people with diabetes live with some level of neuropathy. Inflammation from autoimmune diseases like lupus and rheumatoid arthritis can destroy nerve fibers. The majority of people on dialysis for kidney disease develop neuropathy because excess toxic chemicals accumulate and damage nerves. Infections, both bacterial and viral, are a major cause of neuropathy. Heavy drinking can cause irreversible nerve damage.
Diagnosing Neuropathy Symptoms of neuropathy depend on the type of nerve damaged. Associated with muscle weakness, motor nerve damage symptoms include decreased reflexes, twitching, and cramping. Sensory nerve damage leads to loss of sensation and is a leading cause of falls among older adults. It also causes difficult-to-treat neuropathic pain. Common symptoms of neuropathy include:
Tingling, burning, or numb sensations Hypersensitive to touch Stabbing or shooting pains Muscle cramps and loss of muscle mass Dizziness and balance issues Weakness
To diagnose neuropathy, health care professionals begin with a physical and neurological exam, and gather your medical history. They may order any number of tests and screenings to expand their search or confirm suspicions. Tests might include skin and nerve biopsies and magnetic resonance imaging (MRI) scans.
Nerve conduction velocity tests – used to determine damage to large nerve fibers – and those that measure muscles’ electrical activity help pinpoint neuropathy’s physical effects. Treating Neuropathy The good news for those living with neuropathy is that it is sometimes reversible. Peripheral nerves do regenerate.
Simply by addressing contributing causes such as underlying infections, exposure to toxins, or vitamin and hormonal deficiencies, neuropathy symptoms frequently resolve themselves. In most cases, however, neuropathy is not curable, and the focus for treatment is managing symptoms.
- Assistive devices, pain management, and physical therapy make a tremendous difference for those living with neuropathy.
- Technologies – from specialized footwear to electrical nerve stimulation devices – offer hope for the future.
- Preventing Neuropathy Whether you have to quit smoking, control blood sugar levels, avoid alcohol, or implement aggressive self-care, you can likely manage symptoms and stall neuropathy’s progression.
Some people even make changes to their routine to greatly reduce their risk of ever acquiring it. Eating a healthy diet, exercising regularly, and avoiding bad habits are major steps in that direction. Help make National Neuropathy Awareness Week a success by becoming a part of the effort.
Can you live 20 years with neuropathy?
Disease progression – Prognosis also is related to disease progression, which can vary among early- and late-onset patients. Early-onset patients, whose symptoms appear between the ages of 30 and 50, usually experience more rapid disease progression. Disease progression is reportedly slower — with a survival rate of up to 20 years — among patients who develop symptoms later on, after the age of 50.
Does neuropathy worsen with age?
Who does peripheral neuropathy affect? – Peripheral neuropathy can affect anyone, regardless of age, sex, race or ethnicity, personal circumstances, medical history, etc. However, some people are at greater risk for specific types of peripheral neuropathy (see below under Causes and Symptoms for more about this).
Does neuropathy ever stop?
Peripheral Neuropathy Treatment – Usually a peripheral neuropathy can’t be cured, but you can do a lot of things to prevent it from getting worse. If an underlying condition like diabetes is at fault, your healthcare provider will treat that first and then treat the pain and other symptoms of neuropathy.
- In some cases, over-the-counter pain relievers can help.
- Other times, prescription medicines are needed.
- Some of these medicines include mexiletine, a medicine developed to correct irregular heart rhythms; antiseizure drugs, such as gabapentin, phenytoin, and carbamazepine; and some classes of antidepressants, including tricyclics such as amitriptyline.
Lidocaine injections and patches may help with pain in other instances. And in extreme cases, surgery can be used to destroy nerves or repair injuries that are causing neuropathic pain and symptoms.

What drug can reverse neuropathy?
Study finds drugs that can reverse nerve damage January 18, 2017 — People who suffer from chronic numbness or pain and tingling in their extremities, caused by diabetes or other conditions, might soon get relief. A study by an international team of researchers has found that a class of drugs prescribed for other medical issues such as nearsightedness, incontinence or peptic ulcers may also prevent numbness and pain in fingers, arms and legs.
Led by Dr. Paul Fernyhough of the University of Manitoba and St. Boniface Hospital Albrechtsen Research Centre, and Dr. Nigel Calcutt of the University of California at San Diego, the researchers found that antimuscarinic drugs such as atropine or pirenzepine can reverse the numbness and pain, called neuropathy, often experienced by people with diabetes, HIV, or as a side effect of cancer chemotherapy.
“The costs of treating these diseases and associated morbidities exceed the costs for treating breast cancer. For the first time we have identified a new class of drugs that can reverse nerve damage in animal models of these diseases,” says Fernyhough.
- In peripheral neuropathy the nerve endings of the peripheral nerves die leading to severe impacts on quality of life.
- For example, patients suffer from intractable pain, foot ulcers, infections and ultimately amputations.
- There are presently no treatments other than palliative care.
- The study found that widely-used drugs targeting a key receptor in the neural pathways also regulate the growth of nerve fibres and can stimulate their growth.
The drugs drive nerve fibre regeneration and repair in disease states such as diabetes and chemotherapy where there is otherwise irreversible nerve damage. Calcutt, Fernyhough and Lakshmi Kotra of the University of Toronto together have founded the biotech company WinSanTor to specifically develop the therapeutic potential of this novel approach to treating neuropathy.
“This data opens the possibility that the process of peripheral nerve degeneration may be therapeutically reversible, and now with the potential to use existing drugs, we can rapidly translate these findings to clinical trials,” says Stanley Kim, co-founder and CEO of WinSanTor. “Peripheral neuropathy is a major and often neglected health problem affecting hundreds of millions of people around the world, including a majority of diabetes patients, and we can’t afford to wait any longer in advancing treatments for this disease.” “An exciting aspect of the work is that these are new uses for old drugs,” adds Fernyhough.
Diabetic Neuropathy (DPN) Recovery – The Nerve Doctors
“They have been used in humans for over 20 years with no serious side effects and have an excellent safety profile. We expect Phase 1 trials to progress smoothly with Phase 2 trials arranged and already funded for 2017.” “We are proud of Dr Fernyhough’s exciting finding and the clinical implications of this discovery,” says Dr.
- Grant Pierce, Executive Director of Research at St Boniface Hospital.

UM Today Staff : Study finds drugs that can reverse nerve damage
Can nerves be restored from neuropathy?
Surgery – If your injury does not seem to be healing properly, your surgeon can use EMG testing in the operating room to assess whether scarred nerves are recovering. Doing an EMG test directly on the nerve is more accurate and reliable than doing the test over the skin.
Sometimes a nerve sits inside a tight space (similar to a tunnel) or is squeezed by scarring. In these cases, your surgeon may enlarge the tight space or free the nerve from the scar. Sometimes a section of a nerve is cut completely or damaged beyond repair. Your surgeon can remove the damaged section and reconnect healthy nerve ends (nerve repair) or implant a piece of nerve from another part of your body (nerve graft).
These procedures can help your nerves regrow. If you have a particularly severe nerve injury, your doctor may suggest surgery to restore function to critical muscles by transferring tendons from one muscle to another.
What is the No 1 medical condition that causes neuropathy?
Who is more likely to get peripheral neuropathy? – Most instances of neuropathy are either acquired, meaning the neuropathy or the inevitability of getting it isn’t present from the beginning of life, or genetic. Acquired neuropathies are either symptomatic (the result of another disorder or condition) or idiopathic (meaning it has no known cause). Acquired peripheral neuropathy causes include:
- Physical injury (trauma), such as injury from automobile accidents, falls, sports, and medical procedures that can stretch, crush, or compress nerves, or detach them from the spinal cord. Less severe traumas also can cause serious nerve damage. Broken or dislocated bones can exert damaging pressure on neighboring nerves and slipped disks between vertebrae can compress nerve fibers where they emerge from the spinal cord. Arthritis, prolonged pressure on a nerve (such as by a cast) or repetitive, forceful activities can cause ligaments or tendons to swell, which narrows slender nerve pathways. Carpal tunnel syndrome is a common type of neuropathy from a compressed nerve at the wrist. In some cases, there are underlying medical causes (such as diabetes) that prevent the nerves from tolerating the stresses of everyday living.
- Diabetes is the leading cause of polyneuropathy in the U.S. About 60 to 70 percent of people with diabetes have mild to severe forms of nerve problems that can cause numb, tingling, or burning feet, one-sided bands or pain, and numbness and weakness on the trunk or pelvis.
- Vascular and blood problems that decrease oxygen supply to the peripheral nerves can lead to nerve tissue damage. Diabetes, smoking, and narrowing of the arteries from high blood pressure or atherosclerosis (fatty deposits on the inside of blood vessel walls) can lead to neuropathy. Blood vessel wall thickening and scarring from inflammation of blood vessels can impede blood flow and cause patchy nerve damage in which isolated nerves in different areas are damaged.
- Systemic (body-wide) autoimmune diseases, in which the immune system mistakenly attacks a number of the body’s own tissues, can directly target nerves or cause problems when surrounding tissues compress or entrap nerves.
- Autoimmune diseases that exclusively attack nerves are often triggered by recent infections. They can develop quickly or slowly, while others become chronic and fluctuate in severity. Damage to the motor fibers that go to the muscle includes visible weakness and muscle shrinking, which can produce chronic pain and autonomic symptoms.
- Hormonal imbalances can disturb normal metabolic processes, leading to swollen tissues that can press on peripheral nerves.
- Kidney and liver disorders can lead to high amounts of toxic substances in the blood that can damage nerve tissue. Most individuals on dialysis because of kidney failure develop varying levels of polyneuropathy.
- Nutritional or vitamin imbalances, alcoholism, and exposure to toxins can damage nerves and cause neuropathy. Vitamin B12 deficiency and excess vitamin B6 are the best-known vitamin-related causes. Several medications have been shown to occasionally cause neuropathy.
- Certain cancers and benign tumors cause neuropathy in various ways. Tumors sometimes infiltrate or press on nerve fibers. Paraneoplastic syndromes, a group of rare degenerative disorders that are triggered by the immune system’s response to a cancer, can indirectly cause widespread nerve damage.
- Chemotherapy drugs used to treat cancer cause polyneuropathy in an estimated 30 to 40 percent of people. However, not all chemotherapy drugs cause neuropathy and not everyone receiving chemotherapy will develop neuropathy. Chemotherapy-induced peripheral neuropathy may continue long after stopping chemotherapy. Radiation therapy also can cause nerve damage, sometimes starting months or years later.
- Infections can attack nerve tissues and cause neuropathy. Viruses such as varicella-zoster virus (which causes chickenpox and shingles), West Nile virus, cytomegalovirus, and herpes simplex target sensory fibers, causing attacks of sharp, lightning-like pain. Lyme disease, carried by tick bites, can cause a range of neuropathic symptoms, often within a few weeks of being infected. The human immunodeficiency virus (HIV), which causes AIDS, can extensively damage the central and peripheral nervous systems. An estimated 30 percent of people who are HIV-positive develop peripheral neuropathy; 20 percent develop distal (away from the center of the body) neuropathic pain.
Genetically caused polyneuropathies are rare. Genetic mutations can either be inherited or arise “de novo,” meaning they are completely new to an individual and are not present in either parent. Some genetic mutations lead to mild neuropathies with symptoms that begin in early adulthood and result in little, if any, significant impairment.
