Contributor: Aaron Lessen, MD
Educational Pearls:
- Locked in syndrome results typically from an infarct of the basilar artery leading to infarction of the brainstem but typically preservation of the higher structures
- The result is complete paralysis with preserved cognitive function, hence the name
- Because of their location within the brainstem, ocular movements are sometimes preserved, allowing a patient who recovers from the initial injury to communicate
- Patients typically do not regain any motor function and have a poor prognosis of recovery
- Thrombectomy of the basilar artery is sometimes considered even late after the initial presentation given the devastating prognosis
