Abstract:
Following a right prerolandic stroke, a 76 year old woman with bilateral upper extremity essential tremor (ET) recovered permanently from the latter contralaterally to the affected hemisphere. The ischemic stroke likely interrupted the cortical component of the ET network. Given the magnitude of neuronal loss, post-stroke cortical reorganization was unable to restore this important component of the ET network, accounting for the permanent nature of ET suppression.
