  Finally, neuropathy is classified into mononeuropathy commonly due to entrapment or trauma; mononeuropathy multiplex commonly due to leprosy and vasculitis; and polyneuropathy due to systemic, metabolic or toxic etiology. Laboratory investigations are carried out as indicated and specialized tests such as biochemical, immunological, genetic studies, cerebrospinal fluid (CSF) examination and nerve biopsy are carried out in selected patients. […] The initial step is to confirm whether the signs and symptoms are related to peripheral nerve dysfunction. […] The peripheral nerves comprise sensory, motor and autonomic fibers, which have different lengths, diameters, conduction characteristics and specialized functions. Their involvement therefore results in diverse symptoms, signs and EDx features. Focusing on these symptoms is helpful in the diagnosis of peripheral neuropathy.

• #5 Diagnostic approach to peripheral neuropathy

  https://pmc.ncbi.nlm.nih.gov/articles/PMC2771953/

  Peripheral neuropathy refers to disorders of the peripheral nervous system. They have numerous causes and diverse presentations; hence, a systematic and logical approach is needed for cost-effective diagnosis, especially of treatable neuropathies. A detailed history of symptoms, family and occupational history should be obtained. General and systemic examinations provide valuable clues. Neurological examinations investigating sensory, motor and autonomic signs help to define the topography and nature of neuropathy. […] Electrodiagnostic (EDx) tests include sensory, motor nerve conduction, F response, H reflex and needle electromyography (EMG). EDx helps in documenting the extent of sensory motor deficits, categorizing demyelinating (prolonged terminal latency, slowing of nerve conduction velocity, dispersion and conduction block) and axonal (marginal slowing of nerve conduction and small compound muscle or sensory action potential and dennervation on EMG).

• #6 Diagnostic approach to peripheral neuropathy

  https://pmc.ncbi.nlm.nih.gov/articles/PMC2771953/

  The diagnostic criteria of AIDP are presented in Table 1 and those of CIDP in Table 2. […] The time course study helps in limiting the diagnosis for acute and demyelinating conditions, which have different diagnostic and therapeutic approaches. […] The sensory examination is best performed by testing modalities that subserve large fibers (vibration and joint position) and small fiber (pinprick, pain and temperature) in conjunction with consideration for both focal and length-dependent features since it can provide important diagnostic clues to the likely cause. […] The topography of involvement is helpful in the diagnosis of peripheral neuropathy. On the basis of topography, the neuropathies can be categorized into mononeuropathy, mononeuropathy multiplex and polyneuropathy. […] EDx tests do not provide information regarding the cause of neuropathy but localize the lesion more precisely than on clinical examination alone. EDx provides invaluable help in the diagnosis of acute and chronic inflammatory demyelinating polyradiculoneuropathy, multifocal motor neuropathy with conduction block and entrapment neuropathy (carpal tunnel syndrome, ulnar neuropathy at elbow and peroneal neuropathy at the fibula).

  A number of tests may be used to diagnose peripheral neuropathy and its underlying cause. […] When you see a GP, they’ll ask about your symptoms and examine the affected area of your body. This may involve testing sensation, strength and reflexes. […] The GP may also arrange blood tests, especially to check for causes such as diabetes or vitamin B12 deficiency. […] Some people may need to see a neurologist, a specialist in health conditions affecting the nervous system, in hospital for further tests. […] These may include: a nerve conduction test (NCS), where small metal wires called electrodes are placed on your skin that release tiny electric shocks to stimulate your nerves; the speed and strength of the nerve signal is measured; electromyography (EMG), where a small needle is inserted through your skin into your muscle and used to measure the electrical activity of your muscles.

• #8 Diagnosing Peripheral Neuropathy | NYU Langone Health

  https://nyulangone.org/conditions/peripheral-neuropathy/diagnosis

  Diagnosing peripheral neuropathy can be difficult because the symptoms vary according to the nerves involved and may be vague or overlap with those associated with other conditions. […] During this exam, a doctor evaluates your mental and emotional state and your ability to communicate; your movement, muscle strength, coordination, and balance; and your vision and other senses. The doctor also tests your ability to sense vibration, light touch, body position, temperature, and pain. Testing the senses can reveal sensory nerve damage and indicate the nerves affected. […] A blood test can detect conditions that may be causing peripheral neuropathy, such as diabetes, nutrient deficiencies, liver or kidney dysfunction, and abnormal immune system activity. […] If your doctor suspects an underlying medical condition is contributing to your symptoms, he or she may order an MRI scan.

  The immune system mediates peripheral neuropathies in autoimmune diseases, in systemic diseases such as vasculitis and primary amyloidosis, and in paraneoplastic syndromes. Autoimmune neuropathies are usually divided into Guillain-Barré syndrome (GBS), variants that are of acute onset and self-limiting, and variants that are chronic and follow a progressive or relapsing course. Glycoconjugate antigens, both glycoproteins and glycolipids, have been identified as putative targets for many of these autoimmune polyneuropathies. In general, IgG glycoconjugate autoantibodies have been associated with acute neuropathies, whereas IgM autoantibodies are associated with the chronic neuropathic syndromes. […] Acute immune-mediated neuropathies include GBS (acute inflammatory demyelinating polyneuropathy), acute motor axonal polyneuropathy, acute sensory polyneuropathy, acute autonomic polyneuropathy, and Miller-Fisher syndrome in which the extra-ocular muscles are affected. Increased titers of IgG GM1 or GD1a ganglioside antibodies have been associated with GBS and acute motor axonal neuropathy, whereas increased IgG GQ1b ganglioside antibodies are closely associated with the Miller-Fisher syndrome. Tests for these autoantibodies can help evaluate patients suspected of having these syndromes.

  https://en.wikipedia.org/wiki/Peripheral_neuropathy

  A physical examination will involve testing the deep ankle reflex as well as examining the feet for any ulceration. For large fiber neuropathy, an exam will usually show an abnormally decreased sensation to vibration, which is tested with a 128-Hz tuning fork, and diminished sensation of light touch when touched by a nylon monofilament. […] Diagnostic tests include electromyography (EMG) and nerve conduction studies (NCSs), which assess large myelinated nerve fibers. Testing for small-fiber peripheral neuropathies often relates to the autonomic nervous system function of small thinly- and unmyelinated fibers. These tests include a sweat test and a tilt table test. Diagnosis of small fiber involvement in peripheral neuropathy may also involve a skin biopsy in which a 3 mm-thick section of skin is removed from the calf by a punch biopsy, and is used to measure the skin intraepidermal nerve fiber density (IENFD), the density of nerves in the outer layer of the skin. Reduced density of the small nerves in the epidermis supports a diagnosis of small-fiber peripheral neuropathy.

  The recognition of characteristic clinical phenotypes combined with nerve conduction studies allows pursuing subsequent diagnostic pathways that incorporate nerve conduction studies and additional diagnostic tests. […] Nerve conduction studies (NCS) and needle electromyography (EMG) are carried out to confirm the clinical diagnosis of peripheral neuropathy, exclude neuropathy mimics, reveal subclinical involvement of clinically unaffected nerves and fiber modalities, assess the primary mechanism of damage (axonal vs. demyelinating), and determine disease severity. […] After assigning the patient to a typical clinical pattern, the assessment of primarily axonal versus demyelinating nerve damage by NCS/EMG is a critical next step for further differential diagnosis. […] Clinical pattern #3 requires more extensive laboratory testing, including anti-ganglioside antibodies GM1, GD1a, neurofascin, contactin-1, Caspr1, and anti-myelin associated glycoprotein antibodies.

  Much has been published in recent years regarding pattern recognition as a tool for sleuthing out the etiology of peripheral neuropathy. […] Barohn and Amato suggest a 3-6-10 approach, characterized by 3 goals and 6 key questions, leading to 10 phenotypic patterns facilitating a narrowed and refined diagnostic workup. […] The distinct clinical features of each pattern enable the neuromuscular physician to not only recognize the various patterns of presentation, but customize further diagnostic testing to confirm the clinical impression. […] For ~25% of patients with a peripheral neuropathy in a referral population, etiology remains elusive despite a careful search. After additional workup, a proportion can be attributed to hereditary forms, immunologic causes (acquired demyelinating, e.g., CIDP and variants), paraproteinemia, or undiagnosed medical conditions.

  There is level C evidence that screening laboratory studies be considered for patients with polyneuropathy. This initial evaluation should include a complete blood count, comprehensive metabolic profile, fasting blood glucose, thyroid stimulating hormone, vitamin B12, and serum protein electrophoresis with immunofixation. […] There is level A evidence for genetic testing in patients with suspected hereditary neuropathy and level C evidence in patents with cryptogenic polyneuropathy who exhibit a hereditary neuropathy phenotype. […] There is level C evidence to support that patients with peripheral polyneuropathy should undergo electrodiagnostic testing if symptoms are concerning (i.e., acute onset, asymmetrical, autonomic symptoms, rapidly progressive) or if all initial workup is normal despite persistence of symptoms. […] Peripheral neuropathy outcomes are as varied as their etiologies. Critical illness neuropathy, for example, portends chronic disability and increased hospital mortality, whereas acquired demyelinating neuropathies respond favorably to immunotherapy.

  Peripheral neuropathy (PN), a condition characterized by numbness, pain, or a burning sensation in the feet, often remains undiagnosed or misdiagnosed for other painful conditions. […] A recent study by Gad et al. with our long-time friend Rayaz Malik as senior author (2024) highlights the importance of early diagnosis of PN, particularly diabetic peripheral neuropathy (DPN), the most common form of PN. The authors argue that earlier diagnosis could reduce morbidity and enable earlier risk factor reduction to limit disease progression. […] Currently, the 10g monofilament test is endorsed as an inexpensive and easily performed test for DPN. However, it only detects patients with advanced neuropathy at high risk of foot ulceration. […] There are many validated questionnaires to diagnose PN, but they can be time-consuming and have complex scoring systems. Primary care physicians (PCPs), who often have busy clinics, lack access to a readily available screening method to diagnose PN. They would prefer a short, simple, and accurate tool to screen for PN.

  A lack of awareness of the symptoms among patients may lead to an approximately 5-year delay in the diagnosis and treatment of PN. […] Physicians do not proactively ask patients for symptoms of PN as they prioritize other complications of diabetes, such as retinopathy, nephropathy, and cardiovascular disease. Even if patients complain of neuropathic symptoms, there are no readily available diagnostic tools in the clinic. […] The study by Gad et al. (2024) proposes a consensus to help improve the diagnosis of PN in primary care using a simple tool for patients to screen themselves for PN followed by a consultation with the physician to confirm the diagnosis. […] In conclusion, the study by Gad et al. (2024) underscores the urgent need for a more effective approach to diagnosing PN in primary care. By implementing the proposed consensus, we can hope to reduce the morbidity associated with PN and improve the quality of life for patients suffering from this condition.

• #53 A Survey of the Diagnosis of Peripheral Neuropathy Using Intelligent and Wearable Systems

  https://www.mdpi.com/2227-7080/11/6/163

  A Survey of the Diagnosis of Peripheral Neuropathy Using Intelligent and Wearable Systems […] In this survey paper, the recent research in the development of intelligent wearable systems for the diagnosis of peripheral neuropathy is discussed. […] The main challenge for physicians is to effectively screen an asymptomatic patient for peripheral neuropathy since the symptoms of peripheral neuropathy are not prominent in its early stages, which makes it difficult to diagnose by physicians and requires careful and expert analysis for the diagnosis process. […] For this purpose, nerve conduction studies (NCS) along with electromyography (EMG) are the most widely and effectively used tool for the screening of peripheral neuropathy; however, these techniques are time-consuming, costly, and labor intensive, and it is also not practical to use NCS/EMG in clinical settings. […] This survey paper summarizes the state-of-the-art research work that has been carried out for the diagnosis of peripheral neuropathy using wearable devices that may assist physicians and help maintain the health of patients who are suffering from peripheral neuropathy. […] The main purpose of this survey paper is to present the effectiveness of wearable technology in the diagnosis of peripheral neuropathy, to address the issues that are still present in using wearable devices for the diagnosis of peripheral neuropathy, and to highlight the gap that needs to be addressed in the future in order to make wearable devices more suitable for the diagnosis of peripheral neuropathy. […] The selection of papers was carried out in three steps: (i) initial search in different digital libraries to identify relevant research papers based on their title and abstract; (ii) filtering out of papers based on defined criteria; and (iii) selection of most appropriate research papers. […] The automated diagnosis of peripheral neuropathy (PN) has been performed in many studies where only a single sensor or technique is used for the data acquisition purpose. […] These techniques are based on analyzing foot plantar pressure or gait analysis, vibration- and sensitivity-based confocal microscopic image processing, thermal image processing, ultrasound scanner, and nerve conduction studies (NCS) or electromyography (EMG). […] However, in order to diagnose peripheral neuropathy, a continuous source of data is necessary to diagnose and track the progression of PN. […] Wearable sensors are the most suitable way to collect continuous data, as wearable devices are designed in such a way that they can be easily worn by patients and attached to the human body directly. […] The overall results show that these three gait features can be used to diagnose PN, as they reveal that gait patterns in DPN patients are less extreme and exhibit less sway in the lateral direction. […] The results of this study show that three gait features can play a great role in distinguishing abnormal walking in PN patients. […] The overall study suggests that a significant increase in plantar pressure at the forefoot region was observed in DPN patients in the standing position, while healthy individuals in the standing position put more pressure on the rear foot. […] The results of this research showed that the parametric difference between the right and left foot is an indication of asymmetric plantar pressure distribution. […] The proposed system provides portable and wireless transmission of pressure and temperature sensor data and can be used for long-term monitoring of the foot. […] The overall results showed good specificity and sensitivity.
