Alcoholic neuropathy: Causes, symptoms, and treatment

However, more severe cases may be intractable, even with abstinence, and lead to lifelong impairment. Alcoholic neuropathy is progressive damage to peripheral nerves and, in extreme cases, the autonomic nervous system, through chronic, heavy alcohol use. It is likely to get worse if the person continues to use alcohol or if nutritional problems are not corrected. Alcoholic neuropathy is usually not life threatening, but it can severely affect quality of life. Alcoholic neuropathy is damage to the nerves that results from excessive drinking of alcohol.

  • In both groups AL and CO, the animals showed absence of salivation and lacrimation, normal breathing and palpebral closure, and pupil size with myosis (Table 2).
  • Glucose fluctuation, hyponatremia, hypokalemia, and hypomagnesemia are common features.
  • If you’re dealing with peripheral or diabetic neuropathy, you should work with a medical professional experienced with the condition.
  • The nerve damage of alcoholic neuropathy may be permanent if the damage has been taking place for a long period of time or if it persists.

It has previously been considered in relationship to nutritional, especially thiamine, deficiencies seen in alcoholics. Thiamine deficiency is closely related to chronic alcoholism and can induce neuropathy in alcoholic patients. Ethanol diminishes thiamine absorption in the intestine, reduces hepatic stores of thiamine and affects the phosphorylation of thiamine, which converts it to its active form [12].

What Are the Treatments for Alcoholic Neuropathy?

Damage to nerves caused by alcoholic neuropathy, however, is usually permanent. Regeneration of peripheral nerves takes time and requires the patient and interprofessional team to alcohol neuropathy stages collaborate to improve the patient’s symptoms. Abstinence from alcohol as a part of the treatment plan will help provide the best outcome to enhance the patient’s quality of life.

  • The symptoms of alcoholic neuropathy are caused by the degeneration of nerve cells’ axons from the toxic effects of alcohol, the long fibers that transmit electrical signs from nerve to nerve, and a loss of myelin, the fatty coating that protects nerves.
  • Furthermore, we intend to compare the toxic effect of alcohol on pain central processing to better understand the association between chronic alcohol intake and alcohol-induced neuropathy.
  • Peth on the other hand is a direct alcohol metabolite that can be measured to monitor alcohol consumption as well as for the identification of early signs of alcohol-related clinical manifestations.
  • In general, it takes years for alcoholic neuropathy to develop, so a long-standing history of heavy alcohol use is typical.
  • Motor nerves are the nerves responsible for all voluntary skeletal and somatic movement such as moving the leg or arm.

But if you have developed neuropathy as a result of alcohol use, it’s important to stop drinking as soon as possible. Professional and peer help through programs such as Alcoholics Anonymous or other substance abuse programs can help you reduce your alcohol consumption. Talk to your healthcare provider about the best treatment plan to start on your road to recovery. Alcoholic neuropathy is also caused by nutritional deficiency, as well as toxins that build up in the body. Alcohol decreases the absorption of nutrients, such as protein and vitamin B12, causing significant deficits that affect many areas of the body, including the nerves.

Other areas of the body

Depletion of glutathione increases the susceptibility of neurones to oxidative stress and hyperalgesia [43, 44]. This condition is caused primarily by the toxic effects of alcohol on the nerves, coupled with nutritional deficiencies common in long-term alcohol use. Both the quantity and duration of alcohol consumption play a role in its development. Alcoholic neuropathy is a form of nerve damage caused by excessive alcohol consumption.

This activity describes the evaluation and management of alcoholic neuropathy and reviews the role of the interprofessional team in improving care for patients with this condition. Ethanol and its toxic metabolites affect neural metabolism including metabolic activities in the nucleus, lysosomes, peroxisomes, endoplasmic reticulum, and cytoplasm [104]. The morphological basis of post-alcoholic damage of neural tissue includes primary axonopathy and secondary demyelination of motor and sensory (especially small) fibers [105]. 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].

Role of caspases in alcoholic neuropathy

A person is diagnosed with AUD when he or she meets at least 2 of the 11 criteria in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Multiple research studies indicate that 11% to 66% of people with AUD have alcohol-induced PN. Hawley et al. followed up 11 patients with alcohol-related neuropathy who were abstinent from alcohol and who had begun to consume a normal diet [67]. This identified improvement in sensory symptoms within a few days and a clinical improvement in strength over a period of weeks to months, but in up to 2 years in the most severe cases. There was not however, complete resolution of symmetric neuropathy with persistent mild loss of vibration sense or pinprick sensation in the feet or loss of ankle tendon reflexes.

The distribution of pain and weakness is typically proximal; however, regional or even focal involvement can occur, as detailed in Case 7-4. Muscle destruction may be enhanced by fasting, which commonly occurs in binge drinking. Attacks can be recurrent, correlating with additional episodes of heavy drinking. Recovery following cessation of drinking and repletion of electrolytes is usually rapid and dramatic. Despite repeated episodes, strength typically returns to normal unless a chronic myopathy or other complications are superimposed.

To evaluate the tactile sensitivity of animals, the sensibility test with the Von Frey monofilaments (Touch Test™ Sensory Evaluator Kit of 20 – Leica Biosystems, Germany) was conducted, which is inexpensive and used in the clinical settings as well. These monofilaments were used in an increasing order of thickness (starting at 6 g), on the plantar surface of the pelvic limb of the animal only when it was immobile and standing on the four limbs on a mesh floor. The monofilaments were applied until they bent slightly and were held for two seconds. A limb withdrawal response was valid when the foot was completely removed from the platform (Pitcher et al., 1999). The monofilaments were applied five times at intervals of five seconds, or as soon as the pelvic limb was properly positioned on the platform.
