Which type of tremor worsens as an individual approaches a target during purposeful movement?

Intention tremor is characterized by its exacerbation during purposeful movement, particularly as an individual reaches for a target. This type of tremor is often associated with lesions in areas of the brain that are involved in motor control, such as the cerebellum. As the person gets closer to their intended target, the tremor becomes more pronounced, making it significantly challenging to maintain a steady hand or precision of movement.

In contrast, other types of tremors do not display this specific pattern. Resting tremor occurs when the individual is at rest and typically diminishes during voluntary movement. Postural tremors are noticeable when maintaining a position against gravity but do not worsen with targeted actions. Essential tremor may also intensify with movement but is generally more consistent and does not specifically exacerbate as one approaches a target.

Understanding intention tremor is crucial in clinical settings, especially when diagnosing conditions like multiple sclerosis or other cerebellar disorders, where this symptom may manifest prominently.
