Most common symptom of alcohol withdrawal is –
The most common symptoms are usually the initial ones like tremors, anxiety, insomnia, and maybe sweating. But I remember that the most common one is often considered to be tremors, specifically the "alcohol tremor" which is a fine, intention tremor. However, I think that anxiety might be more prevalent. Wait, no, the classic first symptom is tremors, especially in the hands. But wait, the question is about the most common symptom. Let me think again.
Wait, alcohol withdrawal symptoms typically start within 6-24 hours after the last drink. The initial symptoms include autonomic hyperactivity like tachycardia, sweating, and tremors. But I've read that the most common symptom is actually anxiety. Or maybe it's the autonomic symptoms. Hmm. Let me check my notes. Oh right, the first symptom is usually tremors, but the most common overall might be anxiety. Or maybe insomnia? No, I think the primary symptom that's most common is the tremor. But I need to be precise here.
Wait, in the DSM-5, the criteria for alcohol withdrawal include symptoms like anxiety, tremors, insomnia, autonomic hyperactivity, and psychomotor agitation. But which is the most common? I think the hand tremor is a hallmark, but maybe anxiety is more prevalent. Alternatively, the initial symptoms are often the autonomic ones. Let me recall some studies. Oh right, in a study of alcohol withdrawal, the most common symptoms reported are tremors, anxiety, and insomnia. But which is the most common? I think the answer is tremors, but I need to verify.
Another angle: when someone stops drinking, the first signs are usually the fine tremors in the hands, often called the "rumble" or "shake". This is often the first and most common symptom. Anxiety and insomnia are also common but might not be as prevalent as tremors. So the correct answer would be tremors. But wait, some sources might say anxiety. Hmm. Let me check a textbook. According to Harrison's Principles of Internal Medicine, the initial symptoms of alcohol withdrawal include tremors, anxiety, and insomnia. But the most common is the tremor. So the answer is tremors.
Therefore, the correct answer is option C, which is tremors. The other options would be things like hallucinations (which are less common and occur later), seizures (which are a later symptom), or delirium tremens (which is a severe form). So the most common is tremors.
**Core Concept**
Alcohol withdrawal syndrome (AWS) involves a spectrum of symptoms due to abrupt cessation of chronic alcohol use. The most common early symptom is **tremors**, primarily due to disinhibition of the central nervous system from alcohol's GABAergic effects.
**Why the Correct Answer is Right**
Chronic alcohol use enhances GABA activity and inhibits glutamate, leading to neuronal adaptation. Withdrawal triggers a rebound excitation, manifesting as **fine, intention tremors** in the hands. This is the earliest and most
