About 46% of all chronic alcohol users may eventually develop this condition. How long it takes for alcoholic neuropathy to develop depends on many factors, including the amount of daily alcohol consumed, a person’s age and overall health, their nutritional intake, and other individual factors. But in most cases, alcoholic neuropathy takes several years or even decades to develop, depending on the amount of alcohol consumed. Alcohol-related neuropathy is characterized by damage to the peripheral nerves, which transmit signals between the body, spinal cord, and brain.
Prevalence of alcoholic neuropathy
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. 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.

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. Not only mGluRs but ionotropic glutamate (NMDA) receptors are also involved in alcoholic-induced neuropathic pain.
- Sensory functions and reflexes can be tested during a neurological examination.
- Further, ECG changes and functions of the digestive tract (dyspeptic symptoms, stomach and gallbladder motility, orocecal transit time) can also be assessed 162, 165.
- If you notice you are developing signs of alcoholic neuropathy (such as numbness after drinking alcohol), in addition to seeing a physician, try to stay away from alcohol altogether.
- It has previously been considered in relationship to nutritional, especially thiamine, deficiencies seen in alcoholics.
- Damage to the nerves leads to unusual sensations in the limbs, reduced mobility, and loss of some bodily functions.
During the treatment the regression of neuropathy symptoms, other sensor and movement disorders were observed. The evidence of positive dynamics at peripheral and segmental nerve system level was supported by neurophysiological data. Benfotiamine was found to be beneficial in patients with alcoholic polyneuropathy 98. Coasting is a major feature of alcoholic neuropathy, largely due to chronic alcohol abuse. Even though much research was done in this area, still we do not have a full understanding of the mechanism of alcoholic neuropathy.
- A person’s risk of the neurotoxic effects of alcohol, the quantity and duration of alcohol usage, and nutritional inadequacies are risk factors for developing alcoholic neuropathy.
- You’ll likely also be asked to participate in physical therapy to help regain and maintain your strength.
- The only way to prevent alcoholic neuropathy is not to drink excessive amounts of alcohol.
- Translocation of NFkβ to the nucleus has been reported to result in activation of the endogenous proteolytic enzyme system caspases 69.
- People who drink heavily on a regular basis are at risk of developing this condition.
Clinical management of alcoholic neuropathy
- 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.
- Thus, there is a need to screen acetyl-L-carnitine in both preclinical and clinical models of alcoholic neuropathy.
- Several neuropathy symptoms can occur with damage to the peripheral nervous system, so it’s essential to work closely with your doctor to figure out a plan that’s best for you.
- Alcoholic neuropathy can affect both sensory and motor nerves, causing pain, hypersensitivity, numbness, muscle weakness, and lack of coordination and fine motor controls, largely in the extremities.
The first step in treating alcoholic neuropathy is abstaining from alcohol, sometimes through rehab. Abstinence can prevent the progression and recurrence of neuropathy and, after a few months, improve symptoms in some people. Constant pain in the hands or feet is one of the most bothersome aspects of alcoholic neuropathy. As the condition progresses, the pain may vary in intensity, sometimes diminishing for months before worsening again.
Alcohol-Induced Neuropathy in Chronic Alcoholism: Causes, Pathophysiology, Diagnosis, and Treatment Options
ALN further manifests as weakness and atrophy of muscles due to the damage of greater motor fibers and impaired neuromuscular transmission. ALN can manifest differently, and patients might experience one, two, or even more clinical manifestations of ALN. Patients who have ALN might present such symptoms as cramps, impaired movement of the limbs, muscle atrophy, muscle weakness, spasms, or contractions, loss of sensation, or feeling of tingling.

- Treatment of ALN aims to reduce further damage to the peripheral nerves and restore their normal functioning.
- Ataxia can cause unsteadiness in gait and frequent falls in certain people.
- What is crucial during ALN treatment is the alleviation of the major causation of ALN which is alcohol abuse.
The medical establishment has acknowledged that addiction is a sickness and that certain individuals are more susceptible to it than others. Therefore, to control alcohol consumption disorder, medical assistance is typically required. To rule out other causes of neuropathy symptoms, additional evaluations may involve blood or urine tests, or imaging investigations of the brain or spinal cord.
People who drink heavily on a regular basis are at risk of developing this condition. 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. Alternative therapies like chiropractic care, body manipulation, acupuncture, meditation, and massage therapy can be helpful in managing pain and symptoms of alcoholic polyneuropathy. The main goal of a treatment program for alcoholic polyneuropathy is to improve quality of life and offer relief from symptoms. The best way to prevent alcoholic neuropathy is to avoid excessive alcohol consumption and to seek treatment for alcoholism if you have difficulty doing so. Our muscles need to receive a message from nearby nerves in order to function.
An animal study on axonal transport in vitro using dorsal roots of the sciatic nerve showed decreased axonal transmission after long-term ethanol consumption 106. In vivo study on rats showed impaired retrograde axonal transport 107, 108. Thus, ALN might be induced by the combination of the effects of the direct activity of alcohol metabolites on the nerve fibers along with nutritional deficiencies primarily in a form of thiamine deficiency. 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 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.
Direct toxic effects of ethanol or its metabolites (direct toxicity)
Only the degree of nerve damage is determined by the nerve tests; the cause of neuropathy is not. Tricyclic antidepressants (TCAs) are often Drug rehabilitation the first line drugs to alleviate neuropathic pain symptoms. They have central effects on pain transmission and block the active re-uptake of norepinephrine and serotonin. TCAs have been shown to relieve various neuropathic pain conditions in many trials 115. In agreement with this, one recent study has confirmed the efficacy of TCAs in central pain 116.
