What defines an intention tremor?

An intention tremor is characterized by a tremor that is typically absent at rest and becomes more pronounced as an individual approaches a target during movement. This type of tremor is often associated with damage to the cerebellum, which is responsible for coordinating voluntary movements. As a person tries to perform a precise task or reach a target, the tremor can become noticeable as they get closer, particularly affecting fine motor skills.

The defining feature of an intention tremor is its correlation with the execution of movement rather than being present when the individual is at rest. This makes the correct response especially relevant in understanding how intention tremors can impact daily activities, as they may hinder the ability to perform tasks that require accuracy. Thus, the correct identification of intention tremor aligns with its clinical presentation and origin in neurological conditions that affect the cerebellar function.
