It may also be that comorbid hepatic dysfunction is a risk factor for alcohol-related peripheral neuropathy. Further studies are required to develop a greater understanding of the interaction these entities. Our muscles need to receive a message from nearby nerves in order to function.

Progressive & Permanent Side Effects

  • Many alcohol rehab programs help to manage co-occurring disorders, such as alcoholic polyneuropathy.
  • Nevertheless, heavy alcohol drinkers are usually significantly malnourished because of the improperly balanced diet and impaired absorption of the essential nutrients and elements [58, 59].
  • Thirteen studies provided data from the biopsy of the sural nerve or the skin in patients with alcohol-related peripheral neuropathy.

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]. It has been recognized that spinal cord glial cells, astrocytes and microglia are activated by neuropathic pain or peripheral inflammation [42]. Furthermore, astrocytes and microglia are activated by such pain relevant substances as substance P, calcitonin-gene related peptide (CGRP), ATP and excitatory amino acids from primary afferent terminals, in addition to viruses and alcohol neuropathy stages bacteria [67, 68]. 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].

The Symptoms of Alcoholic Neuropathy and Treatment Options

Drinking a lot of alcohol over a long period of time causes nerve damage that can lead to the onset of alcoholic neuropathy. Someone who struggles with alcoholism may replace meals with alcohol, take in a lot of empty calories, and not maintain a healthy and balanced diet. Alcohol can also deplete the body of essential nutrients, and thiamine (vitamin B1) deficiency is common in people who battle alcoholism. Malnutrition due to alcoholism can contribute to nerve damage and alcoholic polyneuropathy as well.

  • Some other studies have indicated that chronic alcohol intake can decrease the nociceptive threshold with increased oxidative-nitrosative stress and release of pro-inflammatory cytokines coupled with activation of protein kinase C (Figure 1) [10, 16].
  • Sexual drive and performance are diminished in both men and women, including erectile dysfunction in men.
  • As there is no specific amount of alcohol known to induce peripheral neuropathy (Chopra and Twari, 2012) the voluntary intake protocol was an adequate choice to avoid stressful stimuli by treatment.
  • Besides, the key mechanism of chronic pain includes the long-term potentiation of glutamatergic transmission.

Data availability

This may be a reflection of the severity of the neuropathy in which motor nerve function is affected at a later stage. The abnormalities were usually of reduced amplitude, in keeping with axonal loss [2, 3, 5, 11, 12, 16, 21, 27, 37–39, 47, 51, 53, 54, 56, 63–68]. 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]. Particular attention was paid to radial SNAPs, tibial CMAPs, and sural SNAPs due to them being spared in entrapment neuropathies unlike the median, ulnar, and peroneal nerves. The sural nerve was the most commonly reported nerve [2, 3, 5, 11, 27, 37–39, 51, 53, 59, 63, 68]. Motor function of the tibial nerve was the next common [3, 11, 51, 54, 59, 63].

Alcohol-related peripheral neuropathy: a systematic review and meta-analysis

Red blood cells (RBCs) tend to be larger than normal (macrocytosis) and reduced in number from a deficiency in vitamin B9 or B12 or GI bleeding. There may be an increase in erythrocyte macrocytic volume because alcohol interferes with the development of normal RBCs. Glucose fluctuation, hyponatremia, hypokalemia, and hypomagnesemia are common features.

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). Alcohol-induced peripheral neuropathy (PN) is a chronic and painful condition in which the neurotoxic effects of alcohol and nutritional deficiencies cause a pathologic response in nerve function. This article presents the pathophysiology, signs and symptoms, diagnostic approaches, treatment options, and nursing care of patients with alcohol-induced PN. Deficiency of vitamins other than thiamine may also contribute to clinical features of alcoholic neuropathy. Chronic alcoholism can alter the intake, absorption and utilization of various nutrients (nicotinic acid, vitamin B2, vitamin B6, vitamin B12, folate or vitamin E).

  • Alcohol-induced peripheral neuropathy (PN) is a chronic and painful condition in which the neurotoxic effects of alcohol and nutritional deficiencies cause a pathologic response in nerve function.
  • When this message is interrupted due to damaged nerves, the muscles cannot function as they normally would.
  • Motor function of the tibial nerve was the next common [3, 11, 51, 54, 59, 63].
  • The monofilaments were applied until they bent slightly and were held for two seconds.
  • Physical therapy and orthopedic appliances (such as splints) may be needed to maintain muscle function and limb position.

How Does Alcohol Impact Neurological Health?

If you’re struggling to control your drinking and worried about alcoholic neuropathy, help is available. For a list of rehabs and treatment centers near you, visit our rehab directory. The first step in treating alcoholic neuropathy is abstaining from alcohol, sometimes through rehab.

  • The most effective strategy to prevent further neurologic deterioration is for the patient to reduce or discontinue alcohol abuse.
  • Patients may have difficulty buttoning a shirt or blouse and with handwriting and holding objects.
  • Desired outcomes of these medications include reduced pain and improved sleep.
  • This condition is typically not life-threatening, but the nerve damage from alcoholic neuropathy is usually permanent.

Once a person has stopped drinking, they can receive continued care for their nerve damage in addition to treatment for alcohol addiction. Thus, further preclinical and clinical studies are required to assess of this molecule in alcoholic neuropathy. You may need to be sedated for more than a week until the alcohol withdrawal symptoms go away. And a doctor may use brain-imaging techniques to monitor treatment over time. A doctor will take a thorough health history and have you complete questionnaires related to alcohol intake to help diagnose these conditions.
