Alcoholic neuropathy: Causes, symptoms, and treatment

Dina et al. demonstrated the involvement of the sympatho-adrenal stress axis and its final common mediator, epinephrine, in painful alcoholic neuropathy by showing that adrenal medullectomy prevented and reversed the pro-nociceptive effects of alcohol consumption . Thus, following ethanol intoxication, the balance between pro-oxidants and anti-oxidants is disturbed to such an extent that it results in the oxidative damage of biomolecules, such as fats, proteins or DNA, finally leading to cell injury and thus alcoholic neuropathy. The authors concluded that malnutrition, including low blood concentrations of B vitamins, is not a prerequisite for the development of alcoholic neuropathy, and ethanol per se plays a role in the pathogenesis of alcoholic neuropathy. Deficiency of vitamins other than thiamine may also contribute to clinical features of alcoholic neuropathy.

While not specifically approved for the treatment of alcoholic neuropathy, antidepressant medications are often prescribed to help control the pain. If you’re experiencing alcoholic neuropathy symptoms, taking action now can prevent further damage. Recognizing alcohol neuropathy symptoms early is key to preventing further nerve damage. Alcoholic neuropathy is a type of peripheral neuropathy caused by alcohol-related nerve damage. A person should speak with a doctor if they are experiencing any symptoms of alcoholic neuropathy or if they are concerned about their alcohol use.

People with any type of neuropathy may have reduced sensitivity in the legs and arms. Likely a combination of treatments will be needed. Alcoholic neuropathy can’t be reversed, even if you stop drinking. However, they usually worsen over time as the neuropathy progresses.

Signs and Symptoms of Alcoholic Neuropathy

• This may help prevent medicine dependence and other side effects of chronic use.
• However, this seemingly innocuous sensation may be an early warning sign of a condition known as alcoholic neuropathy, a lesser-known but significant consequence of long-term alcohol use.
• The alcohol’s toxic effects on our nerves disrupt the intricate communication network between the brain, muscles, skin, and internal organs.
• Inhibition of the B12- dependent enzyme methionine synthase results in a fall in the ratio of S-adenosylmethionine (SAM) to S-adenosylhomocysteine and the resultant deficiency in SAM impairs methylation reactions in the myelin sheath.

During the early stages of the disease the damage appears reversible when people take adequate amounts of vitamins, such as thiamine. In more severe cases of nutritional deficiency 320 mg/day of benfotiamine for 4 weeks followed by 120 mg/day for 4 more weeks may be prescribed in an effort to return thiamine levels to normal. A liver function test may also be ordered, as alcoholic consumption may cause an increase in liver enzyme levels. Elevated blood creatinine levels may indicate chronic kidney disease and may also be a cause of peripheral neuropathy. One of the first presenting symptoms of diabetes mellitus may be peripheral neuropathy, and hemoglobin A1C can be used to estimate average blood glucose levels. In peripheral nerves, oxidative enzyme activity is most concentrated around the nodes of Ranvier, making these locations most vulnerable to cofactor deprivation.

• Some people with alcohol use disorder also have inadequate food intake.
• However, it is known to be directly related to heavy and long-term alcohol consumption.
• In general, it takes years for alcoholic neuropathy to develop, so a long-standing history of heavy alcohol use is typical.
• If you are having difficulty avoiding alcohol, there are resources that can help you quit.
• Large studies have been conducted and show that alcoholic polyneuropathy severity and incidence correlates best with the total lifetime consumption of alcohol.

Relationship between alcoholic neuropathy and thiamine deficient neuropathy

A schematic diagram of different pathways involved in the pathophysiology of alcoholic neuropathy The exact mechanism behind alcoholic neuropathy is not well understood, but several explanations have been proposed. It has previously been considered in relationship to nutritional, especially thiamine, deficiencies seen in alcoholics. Painful sensations with or without burning quality represent the initial and major symptom of alcoholic neuropathy 2, 4. Treatment is directed towards halting further damage to the peripheral nerves and restoring their normal functioning. Nutritional deficiency (especially thiamine deficiency) and/or the direct toxic effect of alcohol or both have also been implicated in alcohol-induced neuropathic pain.

Alcoholic Neuropathy Symptoms

These agents have central effects on pain transmission and block the active reuptake of norepinephrine and serotonin. Some subjective improvement may appear right away, but this is usually due to the overall benefits of alcohol detoxification. Once an individual stops consuming alcohol it is important to make sure they understand that substantial recovery usually isn’t seen for a few months.

Alcoholic neuropathy

Not only mGluRs but ionotropic glutamate (NMDA) receptors are also involved in alcoholic-induced neuropathic pain. 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. Glutamate concentrations are elevated in the superficial dorsal horn of rats after chronic ligature of the sciatic nerve . Izumi et al. also demonstrated that a single day of ethanol exposure in rats on post natal day 7 results in significant apoptotic neuronal damage throughout the forebrain after 24 h of ethanol administration. These findings constitute direct evidence that spinal PKC plays a substantial role in the development and maintenance of an ethanol-dependent neuropathic pain-like state in rats. Moreover, phosphorylated PKC was significantly increased in the spinal cord following chronic ethanol consumption.

Other areas of the body

Continued alcohol consumption will only worsen the condition. The answer depends on the severity of the nerve damage. However, recognizing the symptoms and seeking medical attention early may minimize the impact of the condition. When significantly limiting or stopping alcohol consumption, receiving ongoing support is essential. There are several possible causes of neuropathy, and knowing about a person’s alcohol intake can help the doctor to make an accurate diagnosis.

Recently findings from our laboratory also suggest the benefecial effects of both α-tocopherol and tocotrienol, isoforms of vitamin E, in the prevention of hyperalgesia and allodynia in rats administered ethanol for 10 weeks . Acetyl-L-carnitine has been tested in clinical and animal studies for the treatment of chemotherapy-induced peripheral neuropathy. Alpha-lipoic acid, the most well-researched nutrient for peripheral neuropathy, has been used as a treatment for peripheral neuropathy in Europe for decades.

This phenomenon may explain the reduced sensitivity to morphine-induced antinociception under the ethanol-dependent neuropathic pain-like state. As supported by immunostaining, the membrane fraction showed that spinal mGluR5 concentrations in ethanol-treated rats were significantly increased compared with those in the control diet group. Miyoshi et al. found that 5 weeks after ethanol treatment, the mechanical nociceptive threshold was significantly decreased and is further reduced up to 10 weeks . This suggests that these pathways are potential targets for novel pharmacological agents for the treatment of inflammatory as well as neuropathic pain . Activator and effector caspases, defining components of programmed cell death signalling pathways, also contribute to pain-related behaviour in animals with small fibre peripheral neuropathies. It has been recognized that spinal cord glial cells, astrocytes and microglia are activated by neuropathic pain or peripheral inflammation .

The single most important step is to stop drinking alcohol immediately. These symptoms are progressive and can severely impact daily life if not addressed early. When these factors combine, the nervous system begins to deteriorate, leading to progressive neuropathy if left untreated. The condition can also lead to digestive issues, urinary problems, and even difficulty walking. There are ways to slow, manage, and sometimes even reverse this condition.

And can alcoholic neuropathy be cured? And what about some alcoholic neuropathy home remedies — do they exist? To prevent alcoholic neuropathy, how much alcohol should you limit yourself to? As yet there is no effective therapeutic intervention available for relieving the neuropathic pain due to chronic alcohol consumption. Thus there is a need to investigate all the above mentioned agents in animal models of alcoholic neuropathy as well clinically in patients suffering from this disorder.

In contrast, the neuropathic symptoms of nonalcoholic thiamine deficiency neuropathy, considered to be identical to beriberi neuropathy , were variable, but typically were motor dominant and acutely progressive, affecting both superficial and deep sensation. Alcoholic neuropathy involves coasting caused by damage to nerves that results from long term excessive drinking of alcohol and is characterized by spontaneous burning pain, hyperalgesia and allodynia. Abstaining from alcohol can help restore your nutritional health, improve your symptoms, and prevent further nerve damage. Damage to nerves from alcoholic neuropathy is usually permanent. These symptoms often respond poorly to treatment in people with alcoholic neuropathy. Some argue it is a direct result of alcohol’s toxic effect on the nerves, but others say factors such as a nutritional deficiency or chronic liver disease may play a role in the development as well.

Treatment for Alcoholic Neuropathy

Treatment will depend on the type, location, and severity of your symptoms. It’s important to share any history of alcohol use with the doctor to receive an accurate diagnosis. A doctor will first perform a physical examination and medical history to assess your symptoms.

Early diagnosis and treatment can help increase your chances of fully recovering. This may cause pain, tingling, and numbing in your limbs. Koppel BS, Weimer LH, Daras M. Nutritional and alcohol-related neurologic disorders. Alcoholic neuropathy is usually not life threatening, but it can severely affect quality of life.

Although benfotiamine therapy was superior to Milgamma-N or placebo for all parameters, results reached statistical significance only for motor function, paralysis and overall neuropathy score. Supplementation with benfotiamine significantly increased concentrations of TDP and total thiamine compared with supplementation with thiamine HCl . In vivo studies using rats have demonstrated impairment of retrograde axonal transport 89, 90. Moreover, they found that the hyperalgesic phenotype in rats which had undergone adrenal medullectomy by administering stress levels of epinephrine was reconstituted. Alcohol consumption potently activates the two major neuroendocrine stress axes, leading to the sustained release of glucocorticoids and catecholamines 17–19. Accumulating evidence suggests a pivotal role for metabotropic glutamate receptors (mGluRs) in nociceptive processing, inflammatory pain and hyperalgesia 74, 75.

Alcoholic neuropathy is a severe condition that can lead how to avoid a relapse when things seem out of control to pain, loss of some bodily functions, and loss of mobility. Alcoholic neuropathy can make daily life difficult, some treatments help by managing the symptoms. The brain is able to control the body and receive sensory information through the peripheral nerves. Alcoholic neuropathy is a severe condition caused by excessive alcohol use. Treatment options include steps to quit alcohol use and managing symptoms of the disease.
