Common movement disorders after stroke in the cerebellar circuits
| Onset | Common phenotype | Involved circuit | Frequent location of stroke (except cerebellum) | |
|---|---|---|---|---|
| Cerebellar outflow tremor | Acute | Intention tremor, w/o postural tremor | Dentato-rubro-thalamic or dentato-rubro-olivary | Posterior thalamus |
| Holmes' tremor | Delayed (1-24 months) | Rest and intention tremor, w/o postural tremor | Both nigrostriatal dopaminergic and cerebello-thalamic/cerebello-olivary | Brainstem or thalamus |
| Palatal tremor | Delayed (1 week-49 months) | - | Dentato-rubro-olivary (Guillain-Mollaret tringle) | Brainstem |
| Asterixis | Acute | Unilateral or occasionally bilateral | Dentato-rubro-thalamic | Thalamus, basal ganglia, midbrain, or frontoparietal cortex |
| Dystonia | Delayed (1 month-15 years) | Focal or segmental | Cerebello-thalamic | Basal ganglia, thalamus, or brainstem |
| Stereotypy | Delayed (1 month) | - | - | Basal ganglia |
w/o: with or without.
