Intention tremors appear with movement and:

Intention tremors appear with movement and:

• A. worsen with stress.
• B. increase during sleep.
• C. are more pronounced when maintaining a posture.
• D. worsen as the target gets closer.

Answer: (D)

Intention tremor reflects cerebellar dysfunction and changes in timing and accuracy during purposeful movement. When you move toward a target, the cerebellum normally helps detect and correct small errors in real-time. If that system is impaired, those errors accumulate as you approach the target, so the tremor grows larger the closer you get. That’s why the tremor is most evident during goal-directed tasks like reaching to touch a finger to the nose or to grasp an object, and it worsens as the movement nears completion. This pattern distinguishes it from tremors that are mainly present at rest (resting tremor) or mainly during sustained posture (postural tremor). The key feature here is the increasing tremor amplitude as the intended movement approaches the target.
