What is What is the cause of delirium tremens in alcoholics? and explain in detail?
Alcohol Withdrawal Syndrome and Delirium Tremens Alcohol withdrawal syndrome typically occurs within 1-2 days of alcohol abstinence and is characterized by autonomic hyperactivity, tremors, insomnia, nausea and vomiting, transient hallucinations, psychomotor agitation, anxiety, and tonic-clonic seizures. Symptoms may be mild for many patients, but if left untreated, it can lead to delirium tremens, an uncommon but severe and life-threatening manifestation of withdrawal marked by severe hallucinations, disorientation, and autonomic overactivity. Symptoms and signs include the following: Profoundly delirious state associated with tremulousness and agitation. Excessive motor activity (most notable as a tremor that affects the face, tongue, and extremities but that may also involve speech) and purposeless activity such as picking at the bedclothes. Hallucinations, classically visual rather than auditory, are a prominent feature. Autonomic nervous system hyperactivity: tachycardia, dilated pupils, fever, and hyperhidrosis. Loss of orientation as to time and place. Such patients are often oblivious to the most obvious features of the surrounding environment. Treatment Note temperature, pulse, and blood pressure, and record results twice hourly to monitor for hyperpyrexia and hypotension.
