This nerve damage causes an individual to experience pain and motor weakness, first in the feet and hands and then progressing centrally. Alcoholic polyneuropathy is caused primarily by chronic alcoholism; however, vitamin deficiencies are also known to contribute to its development. This disease typically occurs in chronic alcoholics who have some sort of nutritional deficiency. Treatment may involve nutritional supplementation, pain management, and abstaining from alcohol. Ammendola and colleagues conducted a study to assess differences between men and women in the development of alcoholic neuropathy. 26 This study used the sural sensory nerve action potential (SNAP) amplitude (ie, nerve conduction study) as the variable measure to detect significant neuropathy in a population of males and females with chronic alcoholism.
What are the symptoms of alcoholic neuropathy?
Many different stimuli, including growth factors, cytokines, viral infection, ligands for heterotrimeric G protein-coupled receptors, transforming agents, and carcinogens, activate the ERK pathway. There are many studies suggesting the role of MEK/ERK signaling in inflammatory pain in male 60–63 and female rats 64. The primary axonal damage and secondary demyelination of motor and sensory fibres (especially small diameter fibres) are considered to constitute the morphologic basis of alcoholic damage to nerve tissue at present 20.
Treatment / Management
In general, it takes years for alcoholic neuropathy to develop, so a long-standing history of heavy alcohol use is typical. Some people experience a faster onset and progression of alcoholic neuropathy than others. It’s not completely clear why some people are more prone to this complication than others. In some instances, a doctor may wish to carry out a nerve biopsy, which involves the harvesting of a small fraction of a nerve (usually from the ankle area) for closer examination using high-powered microscopes. This may well reveal damage-patterns consistent with alcoholic neuropathy across the nerves of the affected area.
What Is Alcoholic Neuropathy?
- In severe cases of alcohol addiction, when a liver transplant is necessary, there have been some instances of reduced symptoms, post-op, but not even a transplant can abate the symptoms of late-stage alcoholic neuropathy.
- 26 This study used the sural sensory nerve action potential (SNAP) amplitude (ie, nerve conduction study) as the variable measure to detect significant neuropathy in a population of males and females with chronic alcoholism.
- As yet there is no effective therapeutic intervention available for relieving the neuropathic pain due to chronic alcohol consumption.
- Acetyl-L-carnitine has been tested in clinical 102 and animal studies 103 for the treatment of chemotherapy-induced peripheral neuropathy.

The role of oxidative stress
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 https://ecosoberhouse.com/ 22. Long-term heavy alcohol use, particularly when accompanied by nutritional deficiencies, can damage the body’s nerves, leading to a host of painful and debilitating symptoms.
Alcohol Neuropathy: Symptoms, Diagnosis, and Outlook
However, there is poor compliance on the part of patients, resulting in the progression of alcoholic neuropathy the condition and ultimately, poor quality of life. Residual neuropathy occurs even in patients who have practiced abstinence. While one may find relief from conventional treatment, the addictive nature or side effects of some medications makes it undesirable to use it for the long term. These treatments, in some cases, only suppress the symptoms but do not treat the underlying pathology.
Treatment of ALN aims to reduce further damage to the peripheral nerves and restore their normal functioning. What is crucial during ALN treatment is the alleviation of the major Alcoholics Anonymous causation of ALN which is alcohol abuse. Alcohol abuse treatment might lead to a resolution of neuropathic pain and alleviation of its symptoms. This can be achieved by complete alcohol abstinence and a balanced diet primarily supplemented by B6, B12, and E vitamins, as well as folate, thiamine, and niacin. Benzodiazepines are commonly used to reduce the symptoms of alcohol withdrawal syndrome; acamprosate and naltrexone are effective to treat alcohol dependence; however, the latter usually induces withdrawal symptoms 175. Further, serotonin-norepinephrine reuptake inhibitors are prescribed to treat alcohol-induced neuropathic pain via exerting antinociceptive properties by increasing serotonergic and noradrenergic neurotransmissions 71.
- Addiction impacted her own family and influenced her compassionate and empathetic relationship with clients.
- You may need to try many therapies and options before you and your medical team work out what is best to manage your side effects, restore nerve function where possible, and prevent further damage.
- 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.
- We’ve all heard the devastating effects of alcohol dependence on the body and the mind.
Alcohol decreases the absorption of nutrients such as magnesium, selenium, and vitamins B1 and B2, causing significant deficits that affect many areas of the body, including the nerves. If the sensation is decreased enough, you may feel actual numbness after drinking alcohol. Yes, long-term excessive alcohol consumption may lead to peripheral neuropathy, which can cause pain in your feet. Contributing factors to PN include vitamin deficiencies, traumautic injuries, diabetes, alcoholism, and others.
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. Resulting disturbances in protein and lipid metabolism lead to undernourishment which adversely influences other metabolic pathways, including those influencing the function of the nervous system. Electrical nerve stimulation sends a small electrical current through the skin and nerves that can help with sensitivities and pain, making it an option for treatment.
