Essential Tremor: Evaluating the Statements
Essential Tremor (ET) is the most common movement disorder causing an action/postural tremor, classically affecting the hands, but also involving the head, voice, and other body parts in a substantial proportion of patients.
Statement-wise Analysis
- Statement 1 — "It may present at any age": Correct. ET has a bimodal age distribution, with peaks in adolescence/early adulthood and again in the sixth decade, but it can begin at virtually any age, including in children.
- Statement 2 — "Head is almost never involved": Incorrect. Head tremor (often a "yes-yes" or "no-no" nodding pattern) is a well-recognized feature of ET and is reported in roughly a third or more of patients, particularly women and those with longer disease duration. Far from being "almost never" involved, head involvement is one of the classic associated features that helps distinguish ET from Parkinsonian tremor.
- Statement 3 — "Tremor may improve with small amount of alcohol": Correct. A characteristic and clinically useful feature of ET is transient dampening of the tremor after ingestion of a small quantity of alcohol, a response not typically seen with Parkinsonian tremor.
Why the Other Options Are Wrong
- 1 and 2 only — Incorrect, because Statement 2 is false; head involvement is a recognized feature of ET, not a rarity.
- 2 and 3 only — Incorrect, because it includes the false Statement 2 while correctly including Statement 3, but omits the true Statement 1.
- 1, 2 and 3 — Incorrect, because it wrongly accepts Statement 2 as true along with the two genuinely correct statements.
Conclusion
Since Statements 1 and 3 are true and Statement 2 is false, the correct answer is "1 and 3 only".
