More persistent intention tremors are often caused by damage to certain regions of the brain. The most common cause of intention tremors is damage and/or degeneration in the cerebellum. The cerebellum is a part of the brain responsible for motor coordination, posture and balance. It is responsible for fine motor movements. When the cerebellum is damaged, a person may have difficulty executing a fine motor movement, such as attempting to touch one's nose with one's finger. One common way for the cerebellum to become damaged is through the development of cerebellar lesions. The most common site for cerebellar lesions that lead to intention tremors has been reported to be the superior cerebellar peduncle, through which all fibers carrying information to the midbrain pass, and the dentate nucleus, which is also responsible for linking the cerebellum to the rest of the brain. Alcohol abuse is one typical cause of this damage to the cerebellum. The alcohol abuse causes degeneration of the anterior vermis of the cerebellum. This leads to an inability to process fine motor movements in the individual and the development of intention tremors. In Multiple Sclerosis, damage occurs due to demyelination and neuron death, which again produces cerebellar lesions and an inability for those neurons to transmit signals. Because of this tight association with damage to the cerebellum, intention tremors are often referred to as cerebellar tremors.
