Alcoholic Neuropathy: Symptoms, Causes, Treatments

Peripheral neuropathy refers to damage or disease of the nerves that carry messages to and from the brain or spinal column and the rest of the body. Peripheral neuropathy can have many causes unrelated to alcohol consumption, and it was previously thought that when it was found in alcoholics it was merely the result of poor nutrition in alcoholics as well as alcohol’s direct impact on nutrients. More recent research, however, suggests that alcohol can directly damage nerves.

Motor symptoms

It is a reliable method to assess alcohol induced tissue damage (Gundersen, 1986). These analyzes can contribute to a better understanding of the AN pathogenesis (Chopra and Twari, 2012). Thirteen studies provided data from the biopsy of the sural nerve or the skin in patients with alcohol-related peripheral neuropathy. Alcohol-related peripheral neuropathy appears to be characterised by severe loss of myelinated fibres; and although profound small fibre loss can also be present, this appears to occur more variably [3, 51, 53, 59, 85]. The data indicates that there is both small and large fibre loss in alcohol-related neuropathy, but that small fibre loss is generally predominant [3, 51, 53, 56, 59, 63, 86]. Accumulating evidence suggests a pivotal role for metabotropic glutamate receptors (mGluRs) in nociceptive processing, inflammatory pain and hyperalgesia [74, 75].

Clinical symptoms associated with alcoholic peripheral neuropathy

• N-acetylcysteine may have application in the prevention or treatment of neuropathy.
• Nerve damage can also make it difficult for you to carry out the functions of daily life.
• There are several studies suggesting the involvement of protein kinases in alcoholic neuropathy.
• Alcohol abuse causes a wide range of disorders that affect the nervous system.
• H and F wave latencies were not routinely reported but were found to be prolonged in those with alcohol-related peripheral neuropathy in studies that did [4, 67].
• Recently, extended release gabapentin relieved symptoms of painful polyneuropathy [120].

Nerves don’t have a resilient ability to regenerate if they are severely damaged. So, the nerve damage of alcoholic neuropathy is generally permanent and likely to worsen if the person does not stop drinking. Alcoholic neuropathy is caused by nutritional deficiency, as well as toxins that build up in the body. Alcohol decreases the absorption alcohol neuropathy stages of nutrients such as magnesium, selenium, and vitamins B1 and B2, causing significant deficits that affect many areas of the body, including the nerves. Alcoholic neuropathy refers to nerve damage resulting from chronic heavy alcohol use. Symptoms may include numbness and tingling in the limbs, muscle weakness, and loss of mobility.

Types and symptoms of alcohol-related neurologic disease

Several mGluR subtypes have been identified in the superficial dorsal horn of the spinal cord [76, 77] and on primary afferent fibres [78]. Glutamate concentrations are elevated in the superficial dorsal horn of rats after chronic ligature of the sciatic nerve [79]. Miyoshi et al. found that 5 weeks after ethanol treatment, the mechanical nociceptive threshold was significantly decreased and is further reduced up to 10 weeks [80]. As supported by immunostaining, the membrane fraction showed that spinal mGluR5 concentrations in ethanol-treated rats were significantly increased compared with those in the control diet group. These findings support the idea that the increased number of membrane-bound mGluR5 following chronic ethanol consumption may lead to a long lasting activation of neuronal protein kinase C in the dorsal horn of the spinal cord. This phenomenon may be responsible for the induction of the neuropathic pain like behaviour following chronic ethanol consumption.

Help transform healthcare

• A doctor will take a thorough health history and have you complete questionnaires related to alcohol intake to help diagnose these conditions.
• Later on, weakness appears in the extremities, involving mainly the distal parts.
• ROS triggers second messengers involved in central sensitization of dorsal horn cells [41] or they activate spinal glial cells which in turn play an important role in chronic pain [42].
• Then, we analyzed each parameter of the neurological domain, evaluating muscle tone, gait, equilibrium, and CNS excitement.

This type of degeneration, so called ‘dying-back’, resembles Wallerian degeneration. Ethanol and its toxic degradation metabolites affect neuronal metabolism including the metabolic pathways of nucleus, lysosomes, peroxisomes, endoplasmatic reticulum and cytoplasm [21]. Alcohol enters the blood as early as 5 min after ingestion and its absorption peaks after 30–90 min. The key role in the degradation of ethanol is played by ethanol dehydrogenase and acetaldehyde dehydrogenase-two step enzymatic systems by which ethanol is converted to acetate which is further metabolized in humans.

Alcoholic neuropathy associated with chronic alcohol intake

The histologic features of sural nerve biopsy specimens demonstrated small fibre predominant axonal loss as characteristic of the pure form of alcoholic neuropathy. Clinical features of alcoholic peripheral neuropathy develop slowly, extending over a period of months and include abnormalities in sensory, motor, autonomic and gait functions. Painful https://ecosoberhouse.com/ sensations with or without burning quality represent the initial and major symptom of alcoholic neuropathy [2, 4]. Later on, weakness appears in the extremities, involving mainly the distal parts. Progressively, the sensory and motor symptoms and signs extend proximally into the arms and legs and finally the gait may become impaired [11].

What are risk factors for alcoholic neuropathy?

The primary treatment for alcoholic neuropathy is seeking help for alcohol use disorder. Talk with your doctor about treatment and support options available to you. These are some other questions people often ask about alcoholic neuropathy. In a 2019 article, researchers explain that breaking down alcohol in the body produces a chemical that damages axons.
