Medical News Today publishes that medical procedures and therapies, medications, and adjunctive and alternative therapies are commonly used to treat alcoholic polyneuropathy. To diagnose alcoholic neuropathy, medical professionals will generally perform a few tests or exams to determine the severity of the disorder and what can be done to treat and manage the symptoms. Malnutrition has been implicated in the pathology of alcohol-related neuropathy by several authors. The data, however, is conflicting as to the role which malnutrition plays. The majority of studies which investigate the relationship between malnutrition and neuropathy focus on thiamine deficiency as an aetiological factor, drawing upon existing knowledge of Beri Beri.
Molecular mechanisms involved in alcoholic neuropathy
Activation of spinal cord microglia, mGlu5 spinal cord receptors, and hypothalamic-pituitary-adrenal axis appear to be implicated in this process [92,93,94,95,96,97]. Oxidative stress also leads to the indirect damage of nerve fibers via the release of free radicals and proinflammatory cytokines with protein kinase C and ERK kinase phosphorylation [98,99,100,101]. Besides, ALN is characterized by insulin and insulin-like growth factor (IGF) resistance, which results in impaired trophic factor signaling [102, 103]. Alcoholic neuropathy occurs when too much alcohol damages the peripheral nerves. This can be permanent, as alcohol can cause changes to the nerves themselves. Deficiencies in B6 and B12, thiamine, folate, niacin, and vitamin E can make it worse.
Acetaldehyde
Acetaldehyde dehydrogenase is a mitochondrial enzyme which undergoes a single amino acid substitution (mutation) in about 50% of the Asian population in a way similar to the genetic changes in sickle cell anaemia [21]. Thus, in alcoholics with the mutated dehydrogenase enzyme, acetaldehyde concentrations may reach values about 20 times higher than in individuals without the mutation. A certain amount of acetaldehyde is not metabolized by the usual pathways (Figure 2) and binds irreversibly to proteins which results in the creation of cytotoxic proteins which adversely affect the function of nervous system cells. These abnormal proteins influence other cell populations especially the hepatocytes where the damage to hepatic mitochondria results in hepatic cirrhosis with reduction of energetic substrates in the liver. The action of these abnormal proteins is explained by competition with normal proteins causing the damage to function and metabolism of the cell [22].
Alcohol-Related Peripheral Neuropathy – History of Discovery and Exact Definition
Uniquely, Vittadini and colleagues found a relationship between the type of alcohol consumed and neuropathy. Specifically, the study demonstrated worse NCS study dysfunction amongst wine drinkers, than those who drank beer or spirits alone [6]. The authors point out that this could be an anomaly due to the wine drinkers consuming more ethanol than other alcohol abusers but offer an alternative alcohol neuropathy stages explanation that wine may contain more toxic impurities than other beverages. Alcoholic neuropathy is a severe condition caused by excessive alcohol use. Damage to the nerves leads to unusual sensations in the limbs, reduced mobility, and loss of some bodily functions. But if you have developed neuropathy as a result of alcohol use, it’s important to stop drinking as soon as possible.

- This activity describes the evaluation and management of alcoholic neuropathy and reviews the role of the interprofessional team in improving care for patients with this condition.
- It was observed that abstinence may lead to the regression of several symptoms of AAN [159].
- Peripheral neuropathy can result from traumatic injuries, infections, metabolic problems, inherited causes and exposure to toxins.
- If you have a diagnosis of alcoholic neuropathy, abstinence from alcohol is the primary treatment to restore nerve function.
- Alcohol-related neuropathy is characterized by damage to the peripheral nerves, which transmit signals between the body, spinal cord, and brain.
- A systematic review suggests that 46.3% of people who engage in chronic heavy alcohol use have alcoholic neuropathy.
- When this message is interrupted due to damaged nerves, the muscles cannot function as they normally would.
- Several mGluR subtypes have been identified in the superficial dorsal horn of the spinal cord [76, 77] and on primary afferent fibres [78].
- Other findings showed that decreased activity of aldehyde dehydrogenase leads to peripheral neuropathy [76, 91].
