Cerebellar stroke will most likely result in which of the following?

Explanation:
The cerebellum coordinates movement, with the midline vermis mainly governing trunk and postural control. A stroke affecting the vermis disrupts axial stability, causing truncal ataxia—an unsteady, wide-based gait and poor sitting balance—often accompanied by nausea due to disruption of vestibular connections. While lesions in the cerebellar hemispheres cause limb (upper or lower extremity) ataxia, the trunk is most prominently affected when the vermis is involved, which is why truncal ataxia with nausea is the most characteristic presentation of a cerebellar stroke. Headache can occur but is not as defining, and coma or quadriplegia would imply more extensive or brainstem involvement.
