More recent research, however, suggests that alcohol can directly damage nerves. The evidence points toward alcohol-related peripheral neuropathy being a form of toxic neuropathy, rather than nutritional neuropathy. The nerves that run outside of the spinal cord and brain are called peripheral alcohol neuropathy stages nerves. They work to send signals throughout the central nervous system and the rest of the body. Nerves help you to move (motor nerves) and feel physical sensations (sensory nerves). Some of your bodily functions are autonomic, which means that you don’t directly control them.
- When speaking with a doctor, a person should be honest about how much alcohol they consume.
- Malnutrition has been implicated in the pathology of alcohol-related neuropathy by several authors.
- Acetyl-L-carnitine has been tested in clinical [102] and animal studies [103] for the treatment of chemotherapy-induced peripheral neuropathy.
- Research suggests you can recover from some or all of the nerve damage caused by alcohol-related neuropathy.
- Those findings indicate that HDAC6 inhibitors could be promising drugs to prevent and treat CIPN.
- The true incidence of alcoholic neuropathy in the general population is unknown, and figures vary widely depending on the definition of chronic alcoholism and the criteria used to detect and classify neuropathy.
- Besides, the key mechanism of chronic pain includes the long-term potentiation of glutamatergic transmission.
Special Health Reports
- Benfotiamine (S-benzoylthiamine O-monophoshate) is a synthetic S-acyl derivative of thiamine (vitamin B1).
- Some people experience a faster onset and progression of alcoholic neuropathy than others.
- 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].
- Alcohol-related liver cirrhosis may occur even a few years earlier in females compared to males [131].
Thus, CIPN is predictable in cancer survivors and should be managed with standardized guidelines. Developing an individualized protocol should be considered to prevent and treat CIPN based on the chemotherapy agent(s) to be used. Based on the most up to date ASCO guidelines, there is no agent recommended for the prevention of CIPN [13]. However, the ASCO does recommend that patients with CIPN should receive reduced or delayed doses and substitute or terminate the chemo agent [13]. Duloxetine (brand name Cymbalta), an agent off-label used to treat CIPN, is the only agent with moderate efficacy [13,51]. Duloxetine inhibits serotonin and norepinephrine reuptakes, which increases the availability of the key neurotransmitters to activate the descending pathway [52].
Direct toxic effects of ethanol or its metabolites (direct toxicity)
The transporters and enzymes, such as fatty acid amide hydrolase (FAAH), which are involved in cannabinoid receptor function, have been targets for discovering drugs for preventing and treating CIPN [97,98]. A few FAAH inhibitors, including ST4070, URB597, URB937, JZL184, and MJN110, have been tested in animal models of CIPN. Administration of these inhibitors reduces the mechanical hypersensitivity and spontaneous pain behavior evoked by cisplatin [153,154,155,156,157,158,159].

Demyelination is probably the effect of axoplasmic transmission slowdown; such degeneration so-called dying back bears semblance to Wallerian degeneration [64, 84]. 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.

- Reduced glutathione is a major low molecular weight scavenger of free radicals in cytoplasm.
- The problems that alcoholic neuropathy causes with muscle weakness, balance, and coordination can make a person more at risk for falling down and getting injured.
- A diet poor in nutrients or avoiding eating can make nutritional deficiencies worse.
- We’ve tried, tested, and written unbiased reviews of the best online therapy programs including Talkspace, Betterhelp, and Regain.
- Treatment will depend on the type, location, and severity of your symptoms.
Additionally, Metformin activates adenosine monophosphate-activated protein kinase (AMPK) which could inhibit the mammalian target of the rapamycin (mTOR) pathway causing nociception blockage [72]. A study was conducted using cisplatin and Paclitaxel, which are drugs known to induce mechanical allodynia. One arm had co-administration of Metformin with cisplatin and the other arm administered Metformin with Paclitaxel [45,72,73]. In a randomized controlled study, metformin 500 mg three times a day was given to patients receiving oxaliplatin in the FOLFOX-4 regimen for colorectal cancer.
How is alcohol-related neurologic disease treated?
- The medical community has recognized that addiction is a disease and some people are predisposed to it.
- Several animal studies have shown the correlation between endocannabinoid systems and peripheral neuropathy induced by several chemotherapy reagents.
- Previous studies have demonstrated a strong correlation between CIPN and increased levels of pro-inflammatory cytokines.
- 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.
