Alcoholic polyneuropathy

Alcoholic polyneuropathy is a neurological disorder in which peripheral nerves throughout the body malfunction simultaneously. It is defined by axonal degeneration in neurons of both the sensory and motor systems and initially occurs at the distal ends of the longest axons in the body. This nerve damage causes an individual to experience pain and motor weakness, first in the feet and hands and then progressing centrally. Alcoholic polyneuropathy is caused primarily by chronic alcoholism; however, vitamin deficiencies are also known to contribute to its development. This disease typically occurs in chronic alcoholics who have some sort of nutritional deficiency. Treatment may involve nutritional supplementation, pain management, and abstaining from alcohol.

This disease typically occurs in chronic alcoholics who have some sort of nutritional deficiency. Treatment may involve nutritional supplementation, pain management, and abstaining from alcohol. Alcoholic polyneuropathy usually has a gradual onset over months or even years although axonal degeneration often begins before an individual experiences any symptoms. An early warning sign (prodrome) of the possibility of developing alcoholic polyneuropathy, especially in a chronic alcoholic, would be weight loss because this usually signifies a nutritional deficiency that can lead to the development of the disease. The disease typically involves sensory and motor loss, as well as painful physical perceptions (paresthesias), though all sensory modalities may be involved. Symptoms that affect the sensory and motor systems seem to develop symmetrically. For example, if the right foot is affected, the left foot is affected simultaneously or soon becomes affected. In most cases, the legs are affected first, followed by the arms. The hands usually become involved when the symptoms reach above the ankle. This is called a stocking-and-glove pattern of sensory disturbances. Polyneuropathy spans a large range of severity. Some cases are seemingly asymptomatic and may only be recognized on careful examination. The most severe cases may cause profound physical disability. Common manifestations of sensory issues include numbness or painful sensations in the arms and legs, abnormal sensations like “pins and needles,” and heat intolerance. Pain experienced by individuals depends on the severity of the polyneuropathy. It may be dull and constant in some individuals while being sharp and lancinating in others. In many subjects, tenderness is seen upon the palpitation of muscles in the feet and legs. Certain people may also feel cramping sensations in the muscles affected and others say there is a burning sensation in their feet and calves. Sensory symptoms are gradually followed by motor symptoms. Motor symptoms may include muscle cramps and weakness, erectile dysfunction in men, problems urinating, constipation, and diarrhea. Individuals also may experience muscle wasting and decreased or absent deep tendon reflexes. Some people may experience frequent falls and gait unsteadiness due to ataxia. This ataxia may be caused by cerebellar degeneration, sensory ataxia, or distal muscle weakness. Over time, alcoholic polyneuropathy may also cause difficulty swallowing (dysphagia), speech impairment (disarthria), muscle spasms, and muscle atrophy. In addition to alcoholic polyneuropathy, the individual may also show other related disorders such as Wernicke-Korsakoff syndrome and cerebellar degeneration that result from alcoholism-related nutritional disorders. The general cause of this disease is prolonged and heavy consumption of alcohol accompanied by a nutritional deficiency. There is some debate over whether the main cause is the direct toxic effect of alcohol itself or whether the disease is a result of alcoholism-related malnutrition. Frequently alcoholics have disrupted social links in their lives and have an irregular lifestyle. This may cause an alcoholic to change their eating habits including more missed meals and a poor dietary balance. Alcoholism may also result in loss of appetite, alcoholic gastritis, and vomiting, which decrease food intake. Alcohol abuse damages the lining of the gastrointestinal system and reduces absorption of nutrients that are taken in. The combination of all of them may result in a nutritional deficiency that is linked to the development of alcoholic polyneuropathy.
