Post-insult valproate treatment potentially improved functional recovery in patients with acute middle cerebral artery infarction.

Animal stroke models suggest that valproate has multiple neuroprotective mechanisms against ischemic brain damage. This study investigated whether valproate improves functional recovery in patients with acute middle cerebral artery (MCA) infarction. This was an open-label controlled trial.

Acute bilateral hearing loss as a "worsening sign" in a patient with critical basilar artery stenosis.

We report a patient who presented with an acute-onset transient vertigo and unsteady gait with bilateral hearing loss. Brain MRI revealed a critical basilar artery (BA) stenosis at the lower pons and infarction in various areas on both sides in the territories of the posterior inferior cerebellar arteries (PICA). Further, we could not visualize the right anterior inferior cerebellar artery (AICA).
