Cerebellar and cerebellar outflow tremors are significant movement disorders that pose therapeutic challenges. These tremors result from disruptions in the cerebellothalamocortical network, particularly affecting key nuclei and pathways. The primary clinical manifestation is an intention tremor characterized by low-frequency, high-amplitude oscillations and is often associated with ataxia and other motor deficits. Cerebellar outflow tremors exhibit diverse features across different states and typically occur after structural lesions in the midbrain or along the dentato-rubro-thalamocortical tract. Neuroimaging and neurophysiological studies highlight tremor as a product of network dysfunction rather than isolated injury. Despite numerous pharmacological attempts, treatment efficacy remains limited, though some patients may benefit from specific medications. Surgical options, including deep brain stimulation, radiofrequency ablation, and MR-guided focused ultrasound of the ventral intermediate nucleus of the thalamus, can provide partial symptom relief, complemented by rehabilitation strategies for functional improvement. Future individualized therapies should consider leveraging precision targeting of the implicated networks.
