Which symptom is NOT commonly associated with a posterior inferior cerebellar infarct?

A posterior inferior cerebellar infarct primarily affects the cerebellum and its associated pathways, leading to symptoms related to balance, coordination, and spatial perception. Ataxia, vertigo, and nystagmus are all common manifestations of this type of infarct due to their connections to cerebellar function.

Ataxia results from the disruption of the cerebellar pathways that control coordinated movements, leading to unsteady gait and difficulties with fine motor skills. Vertigo can occur due to involvement of the vestibular pathways associated with the cerebellum, causing sensations of spinning or dizziness. Nystagmus, characterized by involuntary eye movements, can also result from cerebellar dysfunction affecting the vestibulo-ocular control systems.

In contrast, status epilepticus, which is a series of prolonged seizures without recovery in between, is not a symptom typically associated with a posterior inferior cerebellar infarct. This condition generally stems from other neurological issues, such as seizures originating in the cerebral cortex, rather than dysfunction or damage in the cerebellum. Thus, highlighting that status epilepticus does not align with the symptomatology of a posterior inferior cerebellar infarct signifies its distinction from the other three symptoms, as
