New Tool May Offer Diagnostic Edge for Diabetic Neuropathy

อัพเดทวันที่ 2 กรกฎาคม 2020 เข้าดู ครั้ง

Alcohol can have significant negative effects on the central nervoussystem (CNS). Drinking alcohol can also have negative effects on the peripheral nervous system (PNS). Alcoholic neuropathy occurs when too much alcohol damages the peripheral nerves. This can be permanent, as alcohol can cause changes to the nerves themselves.

  • He is an expert in medical content development, especially in the field of addictions, general health, homeopathic medicine, and pharmaceuticals.
  • This may be a reflection of the severity of the neuropathy in which motor nerve function is affected at a later stage.
  • The action of these abnormal proteins is explained by competition with normal proteins causing the damage to function and metabolism of the cell [22].
  • Patients present with pain, ataxia and parasthesias in the lower extremities.
  • Thus, alpha-lipoic acid may have a potential in the treatment of patients with alcoholic neuropathy.

These relationships make chronic alcoholism a risk factor for thiamine deficiency. In addition to thiamine deficiency, recent studies indicate a direct neurotoxic effect of ethanol or its metabolites. Axonal degeneration has been documented in rats receiving ethanol while maintaining normal thiamine status [5].

Neurological Manifestations of Withdrawal: Shakes, Seizures, and Delirium Tremens

Not only mGluRs but ionotropic glutamate (NMDA) receptors are also involved in alcoholic-induced neuropathic pain. Clinical features of alcoholic peripheral neuropathy develop slowly, extending over a period of months and include abnormalities in sensory, motor, autonomic and gait functions. Painful sensations with or without burning quality represent the initial and major symptom of alcoholic neuropathy [2, 4]. Later on, weakness appears 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]. Progression of symptoms is usually gradual, continuing over months or years [2, 4].

We observed high consumption of alcohol as expected using Two Bottle Choice Paradigm in animal studies (Wayner et al., 1972, Wise, 1973, O’Dell et al., 2004). Worth mentioning, bottles were tested for leakage, an issue that could hinder precise measurement of the solutions. The leakage was negligible, hence, not affecting the calculations of consumption. Also, levels of alcohol in the blood higher than 60 mg/dL confirmed the consistency of this protocol and were compatible with other studies (Bell et al., 2006, Simms et al., 2008a, Simms et al., 2008b). According to Simms et al., 2008a, Simms et al., 2008b, using similar protocol of intermittent alcohol (20%; v/v) ingestion, the alcohol concentration in the blood ranged from 4 to 93 mg / dL in Wistar rats submitted to 20 ingestion sessions. In our study, we observed a blood concentration of 85 mg / dL in the AL group, associating the signs and symptoms of AN observed in this study with this pattern of human consumption (NIAAA, 2022).

Neurotoxic effects of ethanol

These treatments, in some cases, only suppress the symptoms but do not treat the underlying pathology. However, alternative therapies do not have side effect and tackle nutritional deficiencies and oxidative stress. Intensive research has been done on medications like alpha-lipoic acid, benfotiamine, acetyl-l-carnitine, and methylcobalamin. Other botanical or nutrient therapies include myo-inositol, vitamin E, topical capsaicin, and N-acetylcysteine.

A doctor will take a thorough health history and have you complete questionnaires related to alcohol intake to help diagnose these conditions. A diet poor in nutrients or avoiding eating can make nutritional deficiencies worse. Here we discuss a few of the therapeutic options which are tried and could be tried for prevention and treatment of alcoholic peripheral neuropathy. 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.

Signs And Symptoms Of Alcoholic Neuropathy

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 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]. alcoholic neuropathy recovery time As yet there is no effective therapeutic intervention available for relieving the neuropathic pain due to chronic alcohol consumption. Many different stimuli, including growth factors, cytokines, viral infection, ligands for heterotrimeric G protein-coupled receptors, transforming agents, and carcinogens, activate the ERK pathway. There are many studies suggesting the role of MEK/ERK signaling in inflammatory pain in male [60–63] and female rats [64].
