Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The optimal treatment for neurosarcoidosis myelitis is uncertain. We characterize incident neurosarcoidosis myelitis and assess treatment response by MRI and clinical scales. Methods Incident probable or definite neurosarcoidosis myelitis in adults was retrospectively identified from 13 academic medical centers.

Prophylactic Management of Vestibular Migraine: A Systematic Review
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Vestibular migraine (VM) is a neurological disorder characterized by episodic vertigo in patients with migraine, contributing to substantial functional impairment. Although VM is relatively common, a consensus on effective prophylactic treatments is lacking.
