A patient avoided drinking alcohol for 3 days.The patient is a known alcoholic since last 20 yrs.Suddenly he develops restless tremors, agitation. Diagnosis –
**Core Concept**
The patient's symptoms of restless tremors and agitation after avoiding alcohol for 3 days are likely due to withdrawal from chronic alcohol use. This is a classic example of alcohol withdrawal syndrome, which occurs when the body adapts to the constant presence of alcohol and then experiences a rebound effect when it is suddenly stopped.
**Why the Correct Answer is Right**
When an individual with a long history of chronic alcohol use suddenly stops drinking, they can experience withdrawal symptoms due to the abrupt decrease in GABA (gamma-aminobutyric acid) activity in the brain. GABA is an inhibitory neurotransmitter that helps regulate the activity of neurons. Chronic alcohol use leads to an increase in the number of GABA receptors, and when alcohol is suddenly stopped, the brain experiences a rebound effect, leading to an overactivity of neurons and resulting in symptoms such as tremors, agitation, and anxiety.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not address the underlying cause of the patient's symptoms. The patient's history of chronic alcohol use and sudden cessation are key factors in the development of alcohol withdrawal syndrome.
**Option B:** This option is incorrect as it does not provide a clear diagnosis for the patient's symptoms. While the patient may have a history of anxiety, it does not account for the sudden onset of symptoms after stopping alcohol.
**Option C:** This option is incorrect as it does not address the specific symptoms of tremors and agitation. While the patient may have a history of depression, it does not explain the patient's current symptoms.
**Option D:** This option is incorrect as it does not provide a clear diagnosis for the patient's symptoms. While the patient may have a history of sleep disorders, it does not account for the sudden onset of symptoms after stopping alcohol.
**Clinical Pearl / High-Yield Fact**
Alcohol withdrawal syndrome can range from mild to severe and can include symptoms such as tremors, agitation, anxiety, and in severe cases, seizures and delirium tremens. The severity of symptoms can be predicted by the patient's history of chronic alcohol use and the duration of abstinence.
**Correct Answer:** C. Alcohol withdrawal.
