From Wikipedia, the free encyclopedia
Intention tremor, also known as cerebellar tremor, is a dyskenetic disorder characterized by a broad, course, and low frequency (below 5 Hz) tremor of increasing amplitude as an extremity approaches the endpoint of deliberate, visually guided movement (hence the name intention tremor). Intention tremor is usually perpendicular to the direction of movement and one often overshoot or undershoot their target known as dysmetria.[1] [2] It is the result of dysfunction of the cerebellum in particular on ipsilateral side of the lateral zone. Depending on the location of cerebellar damage, intention tremor can be either unilateral or bilateral. [1]
A variety of causes including: damage or degradation of the cerebellum due to multiple sclerosis, degenerative diseases, trauma, tumor, stroke, or toxicity can cause intention tremors. There is currently no established pharmacological treatment specifically for intention tremors, however, some success has been seen using treatments designed for essential tremor. [3] [1] Intention tremors are often seen in conjunction with other cerebellar dysfunctions such as dysarthria (speech problems), nystagmus (abnormal eye movements) and unsteady gait. Postural tremor may also accompany intention tremor. [1]
