Alcoholic neuropathy: possible mechanisms and future treatment possibilities PMC

The direct toxic effects of alcohol and its metabolites (mainly acetaldehyde) are crucial in ALN etiology [64]. It has been demonstrated that incubation of neural cells with advanced glycation end products of acetaldehyde (AA-AGE) induced dose-dependent degradation of neuronal cells while the addition of AA-AGE antibodies reduced neurotoxicity [51, 90]. Other findings showed that decreased activity of aldehyde dehydrogenase leads to peripheral neuropathy [76, 91].

The clinical presentation of alcohol-induced PN is similar to other etiologies of PN. However, the pathophysiology of alcohol-induced PN is different than other forms of PN. Multiple variables contribute to this painful neuropathic syndrome, including the toxic effects of alcohol on neurons and nutritional deficiencies. Alcohol-induced PN can be incapacitating and debilitating, and the patient must also cope with the impact that chronic heavy alcohol consumption has on physical and mental health and personal, social, and professional relationships.

History and Physical

These include direct or indirect effects of alcohol metabolites, impaired axonal transport, suppressed excitatory nerve pathway activity, or imbalance in neurotransmitters. Activation of spinal cord microglia, mGlu5 spinal cord receptors, and hypothalamic-pituitary-adrenal axis also seem to be implicated in the pathophysiology of this alcoholic neuropathy. The goal of treatment is to impede further damage to the peripheral nerves while also restoring their normal physiology.

Between 2012 and 2017, at least 12 people died from respiratory depression while taking gabapentinoids, the agency found. At high doses, the drug can also increase a person’s risk of falls, Shah said. Dr. Latov joined the department of Neurology and Neuroscience of the Weill Cornell Medical College in 2001, where he heads the Peripheral Neuropathy Clinical and Research Center. His clinical and laboratory research interests are in Peripheral Neuropathy and Neuroimmunology, focusing on the diagnosis and and treatment of inflammatory neuropathies.

• The sometimes-conflicting findings between biopsy findings may be representative of the complex interplay of pathological factors in alcohol-related peripheral neuropathy and is indicative of the need for further research in this area.
• It is important to stop drinking if you suffer from alcoholic polyneuropathy in order to stop the disease from getting worse and to correct the nutritional imbalance that is damaging the nerves and interfering with the nervous system.
• The decreases in nerve conduction velocity were significantly less in groups supplemented with acetyl-L-carnitine.
• The histologic features of sural nerve biopsy specimens demonstrated small fibre predominant axonal loss as characteristic of the pure form of alcoholic neuropathy.

• Alcoholic neuropathy damages the nerves due to prolonged and excessive alcohol consumption.
• Rich sources of vitamin B1 include organ meats, beef, pork, poultry, pasta, bread, rice, nuts, whole-grain cereals, and beans.
• For the most part this review consists of non-interventional studies for which generally accepted tools to evaluate risk of bias are not available.
• Treatment is directed toward stopping further damage to the peripheral nerves and returning to normal functioning.
• Injury to these small nerve fibers leads to somatic and autonomic symptoms.
• In fact, a person who drinks heavily might not recognize that the symptoms they are experiencing are related to their alcohol consumption.

This condition is typically not life-threatening, but the nerve damage from alcoholic neuropathy is usually permanent. The first step in treating alcoholic neuropathy includes stopping alcohol use altogether. If your drinking is out of your control, know that many treatment options are available. To investigate the effect of gradient pressure therapy on the prevention of chemotherapy-induced peripheral neuropathy (CIPN) and improvement in activities of daily living (ADL) in patients with breast cancer. There are several different factors that can worsen or exacerbate neuropathy in your feet. “Neuropathy can be aggravated by uncontrolled blood sugar levels in diabetics.

Fortunately, most symptoms of Morton’s neuroma resolve with conservative treatments, and surgery is usually unnecessary. If you wear tight, pointy-toed, high-heeled, or otherwise binding shoes, changing your footwear is a must. Wearing flats (or low heels) and roomy shoes with a wide toe box that lets your foot decompress may help to relieve symptoms. Here’s an overview of the condition, its causes, symptoms and treatment options from NY-based orthopedic foot and ankle specialist, Stuart Katchis, M.D. “If we’re able to, with gabapentin, kill two birds with one stone — able to treat their pains as well as their alcohol use disorder — then it’s warranted, using gabapentin versus just using acamprosate,” he said. And, notably, trials of gabapentin against placebo as a treatment for alcohol use disorder and withdrawal have had mixed results (an extended-release version failed to work better than placebo).

• These effects are usually not as severe when it only affects one nerve or a limited group of nerves.
• Therefore, topical application with capsaicin may provide symptomatic relief from neuropathic pain in patients suffering from alcoholic neuropathy.
• Plus, the soft, stretchable interiors have foam padding to prevent irritation and painful rubbing.
• As yet there is no effective therapeutic intervention available for relieving the neuropathic pain due to chronic alcohol consumption.
• Ahead, we consulted podiatrists on the very best shoes for neuropathy that are lightweight, supportive, and comfortable—and what to consider when shopping for a new pair.

It’s also sometimes possible to stop or reverse certain types of neuropathies if treatment begins quickly enough. Because of these factors, you shouldn’t try to self-diagnose and self-treat it. A healthcare provider is the best person to guide you in managing this condition. The prevalence of impairments in ANS in alcohol-dependent patients varies from 20 to 99% [160]. Symptoms of AAN are due to impairments in both sympathetic and parasympathetic autonomic fibers of the cardiovascular, digestive, and urogenital systems. The reduction of internodal length contributes to the decreased speed of nerve conduction which may be implemented in impairments in perspiration, baroreceptor reflexes, and functions of internal organs.

• However, this can still vary, so it’s best to ask your healthcare provider about what’s most likely in your case.
• Primarily, it was assumed that the progression of ALN symptoms is due to malnutrition and micronutrient deficiency (mainly B1 hypovitaminosis) [82, 83].
• Patients may be severely malnourished and dehydrated with electrolyte imbalances.
• The main symptoms of ALN include dysesthesia, paresthesia, numbness, and pain in the lower extremities which progressively reach higher parts of the body [114,115,116,117].
• It is important to share any history of alcohol use with your doctor to get an accurate diagnosis.

Medical Issues/Complications

Benfotiamine was found to be beneficial in patients with alcoholic polyneuropathy [98]. Behse & Buchthal [31] compared 37 Danish patients with alcoholic neuropathy alcohol neuropathy stages with six patients with nonalcoholic post gastrectomy polyneuropathy. The authors noted that Danish beer at the time of the study contained thiamine and vitamin B6.
