Migraine history affects vestibular ocular motor screening, King-Devick, and reported symptoms in collegiate student-athletes: Findings from the concussion assessment, research, and education consortium

Abstract Background: Migraine, a common neurological disease, can negatively impact vestibular and oculomotor functioning. Vestibular and oculomotor function and symptomology are routinely tested in collegiate athletes as part of...

Impact of levodopa and deep brain stimulation on visual impairments in Parkinson’s disease

Abstract Background: Parkinson’s disease (PD) often causes visual changes that impair visuospatial processing, reading speed, and contrast acuity, impacting patients’ quality of life. Objectives: This study aimed to investigate...

Reading and Eye-Tracking Metrics as Visual Function Indicators for Patients with Optic Neuropathies

Abstract Purpose: Disruptions in visuomotor behavior are common in individuals with neuro-ophthalmic conditions but rarely assessed at point-of-care locations. This study uses a simple visuomotor reading task to evaluate...

A Multimodal Approach for Early Identification of Mild Cognitive Impairment and Alzheimer’s Disease With Fusion Network Using Eye Movements and Speech

Abstract Detecting Alzheimer’s disease (AD) in its earliest stages, particularly during an onset of Mild Cognitive Impairment (MCI), remains challenging due to the overlap of initial symptoms with normal...

Effect of methylphenidate on oculomotor function in individuals with multiple sclerosis: a pilot randomized placebo-controlled trial

Abstract Introduction: Individuals with multiple sclerosis (MS) frequently experience visual and oculomotor symptoms that may impact and confound neuropsychological assessments of information processing speed (IPS). In this study, we...

Computer-based Eye-tracking Analysis of King-Devick Test Differentiates Persons With Idiopathic Normal Pressure Hydrocephalus From Cognitively Unimpaired

Abstract Background: Functional defects in eye movements and reduced reading speed in neurodegenerative diseases represent a potential new biomarker to support clinical diagnosis. We investigated whether computer-based eye-tracking (ET) analysis...

Post-Concussion Assessment as a diagnostic and mechanistic framework for treating patients with Long COVID

Abstract Introduction: Despite first coming into view over two years ago, effective diagnostic and treatment pathways for Long COVID continue to evade the medical community. The overlap in neurological-based...
