Alcohol abuse contributes to peripheral neuropathy development involving both somatic and autonomic nerves [154, 155]. However, impairments of autonomic functions are scarcer and less intensified, and, usually, clinical symptoms are delayed [156]. According to many studies, alcohol-induced autonomic neuropathy (AAN) not only leads to potential damage to internal organs but also increases the mortality rate of patients [157, 158]. It was observed that abstinence may lead to the regression of several symptoms of AAN [159]. Regarding the autonomic domain, our findings were just significant for piloerection. However, data from literature indicate additional autonomic alterations in long-term chronic users (Milovanovic et al., 2009).

Other studies have shown a direct, negative effect from alcohol and its many metabolites on the nervous system. Axonal degeneration and demyelination of neurons were seen in both humans and lab mice receiving alcohol. The cause is a diverse multifactorial process caused from damage by free radicals, the release of inflammatory markers, and oxidative stress. Avoiding excessive amounts of alcohol is the primary way to prevent alcoholic neuropathy.

Symptoms & Signs

And if it is diabetes, you’re probably already experiencing things like a loss of eyesight or kidney damage. There’s a chance you will see positive changes if you change your diet right away. In the most severe cases, these infections may lead to amputation or death, so you need to seek immediate medical care. No matter what type of neuropathy you have, if you reach stage three, your injuries can lead to more severe infections, such as sepsis and gangrene.

• In an animal model, Kaur et al. (2017) showed that curcumin and sildenafil administrated alone or in combination represent a therapeutic advantage in alcohol-induced neuropathic pain [176].
• Patricia began her career at Presbyterian Intercommunity Hospital in Whittier.
• Not only mGluRs but ionotropic glutamate (NMDA) receptors are also involved in alcoholic-induced neuropathic pain.

She is currently pursuing a degree in Clinical Psychology with plans to continue helping the lives of people suffering from addictions, mental health, and co-occurring disorders. Dolly brings with her great compassion, empathy and her commitment to a life of service and recovery. Diagnosis usually involves a healthcare provider collecting a medical history, performing a medical and neurological exam, and performing blood and urine tests. Treatment options include steps to quit alcohol use and managing symptoms of the disease.

How we reviewed this article:

Patients who abuse alcohol tend to consume fewer calories and have poor absorption of nutrients in the gastrointestinal tract. There are also direct toxic effects of alcohol and its metabolites on neurons affecting cellular cytoskeletons and demyelination of neurons. Alcoholic neuropathy is a condition in which the nerves become damaged as a result of years of heavy alcohol consumption. Symptoms include burning pain in the body, hyperalgesia (increased sensitivity to pain), and allodynia (a condition in which normal stimulus, like a soft touch, produces pain). The evidence is accruing that ALN should be reclassified as a toxic, rather than nutritional neuropathy. ALN has clinical and electrophysiological features distinct from but overlapping with neuropathy from pure thia-mine deficiency (beriberi).

Malnutrition has been implicated in the pathology of alcohol-related neuropathy by several authors. The majority of studies which investigate the relationship between malnutrition and neuropathy focus on thiamine deficiency as an aetiological factor, drawing upon existing knowledge of Beri Beri. A smaller alcohol neuropathy stages number of publications do attribute thiamine deficiency, but generally speaking these studies were older or of lower quality evidence [4, 6, 30, 58, 76, 77]. The median and ulnar nerves are evaluated for motor function and the median, ulnar, and sural nerves are evaluated for sensory function.

Signs and symptoms

Electrophysiologic and pathologic findings mainly indicate axonal neuropathy with reduced nerve fibre densities. 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]. Subperineurial oedema is more prominent in thiamine deficient neuropathy, whereas segmental de/remyelination resulting from widening of consecutive nodes of Ranvier is more frequent in alcoholic neuropathy [3].

Alcoholic Neuropathy: Symptoms and Treatment

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. ALN with thiamine deficiency was manifested as a variable mixture of these symptoms. It was proposed that ALN pathogenesis, besides thiamine deficiency itself, could be due to its inappropriate use in the organism or transketolase deficiency [150].

• Furthermore, females tend to be more vulnerable to the brain damage and neurotoxic effects of alcohol [134].
• Likewise, thermal sensitivity alterations are common in neuropathic patients and easily evaluated in animal models.
• The pathophysiology of ALN involves underlying mechanisms that include direct or indirect effects of alcohol metabolites, impaired axonal transport, suppressed excitatory nerve pathway activity, or imbalance in neurotransmitters [52,53,54].
• Based upon these results, vitamin supplementation appears to exert a positive therapeutic effect in alcohol-related neuropathy.
• There are several studies suggesting the involvement of protein kinases in alcoholic neuropathy.
