Identification of Stroke and TIA in Patients With Acute Dizziness, Vertigo or Imbalance in Emergency Departments of Primary Care Hospitals: Early Experiences With a Network-Based Telemedical Approach.

Background: Acute dizziness, vertigo, and imbalance are frequent and difficult to interpret symptoms in the emergency department (ED). Primary care hospitals often lack the expertise to identify stroke or TIA as underlying causes. A telemedical approach based on telestroke networks may offer adequate diagnostics and treatment.

Feasibility of Telemedical HINTS (Head Impulse-Nystagmus-Test of Skew) Evaluation in Patients With Acute Dizziness or Vertigo in the Emergency Department of Primary Care Hospitals.

Background: Acute dizziness, vertigo and imbalance are common symptoms in emergency departments. Stroke needs to be distinguished from vestibular diseases. A battery of three clinical bedside tests (HINTS: Head Impulse Test, Nystagmus, Test of Skew) has been shown to detect stroke as underlying cause with high reliability, but implementation is challenging in primary care hospitals.

Probing Early Motion Processing With Eye Movements: Differences of Vestibular Migraine, Migraine With and Without Aura in the Attack Free Interval.

Background: Migraineurs, in between headache attacks, have a different sensitivity to sensory motion stimuli compared to non-migraineurs.

Methods: This cross-sectional laboratory study examines the motion processing in migraineurs using ocular following responses (OFR) elicited by large field random dot patterns and open-loop smooth pursuit eye movements (PS) elicited by a single target moving on a homogenous background. Eye movements were recorded with a video-oculographic system (EyeSeeTec ) and stimuli presented on a CRT at 100 Hz repetition rate to horizontal stimuli of a velocity of 2.
