The demyelination is explained as the result of a slowing down (decceleration) of axoplasmic flow and a degradation of the quality of biological properties of axonal enzymes and proteins. 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.

Also, the results of the group of 32 patients with non-alcoholic thiamine deficiency neuropathy were considered. Thiamine deficiency resulted in the progression of sensory dysfunctions; further, histological examination of the sural nerves revealed the loss of small nerve fibers and segmental demyelination. Patients with non-alcoholic thiamine deficiency neuropathy showed more abrupt onset of symptoms, mainly in a form of motor dysfunctions; biopsy showed damage to greater fibers with subperineurial edema. ALN with thiamine deficiency was manifested as a variable mixture of these symptoms.
Alcohol-Related Neurological Effects and Diseases
At Healthgrades, our Editorial Team works hard to develop complete, objective and meaningful health information to help people choose the right doctor, right hospital and right care. https://ecosoberhouse.com/ Our writers include physicians, pharmacists, and registered nurses with firsthand clinical experience. All condition, treatment and wellness content is medically reviewed by at least one medical professional ensuring the most accurate information possible. In a 2019 article, researchers explain that breaking down alcohol in the body produces a chemical that damages axons. Axons are the groups of nerve fibers that carry impulses between the brain and the nervous system.
General Health
Spinal cord glial cells are implicated in the exaggerated pain state created by diverse manipulations such as subcutaneous inflammation, neuropathy and spinal immune activation 65, 66. Drug rehabilitation It has been recognized that spinal cord glial cells, astrocytes and microglia are activated by neuropathic pain or peripheral inflammation 42. Thiamine serves as an important coenzyme in carbohydrate metabolism and neuron development. The lack of thiamine in the nervous system affects the cellular structure and can cause cell membrane damage and irregular ectopic cells. Other vitamin deficiencies seen with alcohol abuse include but are not limited to, B vitamins, folic acid, and vitamin E.
The development of alcoholic neuropathy is a gradual process that occurs over an extended period of excessive alcohol consumption. It typically takes years of chronic alcohol consumption to manifest symptoms of alcoholic neuropathy. The duration and intensity of alcoholism, along with individual factors such as genetics and overall health, can influence the onset and progression of the condition. Keep in mind, not everyone who abuses alcohol will develop alcoholic neuropathy, as susceptibility can differ among individuals. Alcoholic neuropathy is a type of peripheral neuropathy, which means it affects the nerves outside the brain and spinal cord. The toxic effects of alcohol on nerve tissue, combined with nutritional deficiencies caused by alcohol abuse, can lead to nerve damage and dysfunction.
Both the toxicity of alcohol and nutritional deficiencies have been linked with alcoholic neuropathy, which is one of the most common but least recognizable consequences of heavy alcohol use. Learn more about this condition, including its symptoms, how it’s treated, and ways to cope. Among patients with chronic alcohol use disorder, neuropathy is the most common harmful sequelae. It is estimated that in the United States, 25% to 66% of chronic alcohol users alcohol neuropathy stages experience some form of neuropathy; however, the true incidence in the general population is unknown. The majority of patients were middle-class, working men, and continuous drinkers were more affected than episodic drinkers. Women are more likely to develop alcohol polyneuropathy and suffer from a more rapid onset and greater severity.
- In many, if not most, cases, improvements in symptoms are seen with continued abstinence from alcohol.
- Alcoholic neuropathy refers to nerve damage resulting from chronic heavy alcohol use.
- Certain vitamin supplements, including folic acid and thiamine, will likely be provided to you during treatment since people with ALN tend to be deficient in these areas.
- Besides, the key mechanism of chronic pain includes the long-term potentiation of glutamatergic transmission.
- Chronic abuse of alcohol depletes the pool of liver proteins which are consumed for energy production and insufficient intake of proteins only worsens this imbalance.
Alcohol Abuse and Nerve Damage
- Research suggests that up to 66% of people with AUD have some type of alcohol-related neuropathy.
- While peripheral neuropathy generally cannot be cured, there are several medical treatments that can be used to manage the pain of alcoholic neuropathy, aiding in your recovery.
- Alcoholic neuropathy is a condition in which the nerves become damaged as a result of years of heavy alcohol consumption.
- Biomarkers of alcohol abuse include carbohydrate-deficient transferrin (CDT) and phosphatidylethanol (PEth).
Due to similar histologic and electrophysiological symptoms, it was believed that ALN may make up a subtype of beriberi 146. Further research has confirmed the role of thiamine in the pathogenesis of ALN—the well-balanced diet and vitamin B1 supplementation significantly decreased the severity of ALN symptoms 147, 148. However, the limitations of those studies include the lack of the possibility to measure the amount of vitamin B1 in the serum; further, patients who were involved in the study have received an unrefined form of the supplement. Koike et al. (2003) compared clinical and histological differences between ALN with and without thiamine deficiency 65.
This damage prevents the nerves from communicating information from one body area to another. There are no medications that can help improve loss of sensation, strengthen muscle weakness, or assist with the coordination and balance problems caused by alcoholic neuropathy. However, some people notice an improvement in symptoms a few months after discontinuing alcohol intake. The diagnosis of alcoholic neuropathy involves a combination of medical history, physical examination, and possibly blood tests or nerve tests such as electromyography (EMG) and nerve conduction studies (NCV).
