The mechanism of this is presently unclear, one possible explanation is that is resolves concomitant vitamin-dependent neuropathy which exacerbates alcohol-related neuropathy. When speaking with a doctor, a person should be honest about how much alcohol they consume. There are several possible causes of neuropathy, and knowing about a person’s alcohol intake can help the doctor to make an accurate diagnosis. Physical exam findings include diminished sensation to vibration, pain, dysfunctional thermo-proprioception, weakness in the ankle and toes with flexion and extension, atrophy of foot muscles, gait ataxia, and diminished deep tendon reflexes. Keep moving forward, one day at a time, and appreciate the hard work you put in along the way.

Symptoms of Alcoholic Neuropathy
This measure has been explored as a risk factor for the development of autonomic neuropathy. Caspases, or cysteine-aspartic acid proteases, are a family of cysteine proteases, which play an essential role in apoptosis (programmed cell death), necrosis and inflammation. Translocation of NFkβ to the nucleus has been reported to result in activation of the endogenous proteolytic enzyme system caspases 69. Joseph & Levine 71 suggested that activity in signaling pathways that ultimately lead to apoptosis plays a critical role in the generation of neuropathic pain, before death of sensory neurones becomes apparent.
How we reviewed this article:
- Treatment should be focused on alcohol sobriety and the replacement of key nutrients.
- Total lifetime dose of ethanol (TLDE) is often measured in studies to establish the extent of alcohol abuse.
In these studies, it is clear that those with liver disease have an increased prevalence of autonomic dysfunction, but that this is even higher in the context of alcoholic cause of liver disease 48–52. Drug rehabilitation Four studies specifically correlated the duration of alcohol abuse with presence of autonomic dysfunction through abnormal findings in cardiovascular parameters; however, the literature is conflicting 21, 22, 29, 38. A study by Malpas et al. considered groups of chronic alcohol abusers with and without vagal neuropathies, finding no differences between these groups with respect to duration of alcohol abuse or age 24. Furthermore, two studies showed no correlation between either cardiovascular autonomic dysfunction or abnormal sympathetic skin response and duration of alcohol abuse, although these studies did not appear to adjust for age 40, 41.
2.2. Quantitative Sensory Testing (QST)
Risk factors for developing alcoholic neuropathy include the amount and duration of alcohol consumption, nutritional deficiencies, and individual susceptibility to alcohol’s neurotoxic effects. People who consume large quantities of alcohol over an extended period, who would qualify as alcoholics, are at higher risk, especially if their diet lacks vital nutrients needed for nerve function and repair. Genetic factors may also play a role, making some individuals more prone to alcohol-related nerve damage than others. Additionally, overall physical health, liver function, and concurrent use of other substances can influence the onset and severity of neuropathic symptoms. Chronic, excessive alcohol consumption is known to relate to diseases of both the central and peripheral nervous system.
The hyperalgesia was acutely attenuated by intradermal injection of nonselective PKC or selective PKCε inhibitors injected at the site of nociceptive testing. Western immunoblot analysis indicated a higher level of PKCε in dorsal root ganglia from alcohol-fed rats, supporting a role for enhanced PKCε second messenger signalling in nociceptors contributing to alcohol-induced hyperalgesia 16. Miyoshi et al. 15 found that a significant decrease in the mechanical nociceptive threshold was observed after 5 weeks of chronic ethanol consumption in rats. Injection of (S)-2,6-diamino-N-1-(oxotridecyl)-2-piperidinylmethyl hexanamide dihydrochloride (NPC15437), a selective PKC inhibitor, once a day for a week after 4 weeks of ethanol treatment.
- Nerves that are part of the autonomic nervous system help to regulate heart rate, body temperature, respiration, and blood pressure.
- As the condition progresses, the pain may vary in intensity, sometimes diminishing for months before worsening again.
- Deficiencies in these nutrients can harm overall health and prevent nerves from functioning correctly.
Avoiding excessive amounts of alcohol is the primary way to prevent alcoholic neuropathy. 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. If you are having difficulty avoiding alcohol, there are resources that can help you quit. While not specifically approved for the treatment of alcoholic neuropathy, antidepressant medications are often prescribed to help control the pain. Anti-seizure medications are sometimes prescribed as a way to manage pain.
- Two studies acknowledged that recruited patients were indeed taking drugs which could potentially affect the reliability of the results 40, 48.
- Only one study commented on the relationship between physical fitness and autonomic dysfunction in alcohol abusers and found an inverse relationship 54.
- Densities of small myelinated fibres and unmyelinated fibres were more severely reduced than the density of large myelinated fibres, except in patients with a long history of neuropathic symptoms and marked axonal sprouting 2.
- Poor absorption and low intake of these vitamins have clinical features of dermatitis, neuropathy, and anorexia.
Painful sensations with or without burning quality represent the initial and major symptom of alcoholic neuropathy 2, 4. Later on, weakness appears neuropathy from alcohol use in the extremities, involving mainly the distal parts. Progressively, the sensory and motor symptoms and signs extend proximally into the arms and legs and finally the gait may become impaired 11.
