Visual Disability and Reading Difficulties in Patients with Parkinson’s Disease

Introduction: Parkinson’s Disease (PD) is the second most common neurodegenerative disease globally. While the majority of PD patients report difficulties with vision (1-3), few studies have examined reading in...

The King–Devick test as a predictor of cognitive effects after chronic partial sleep restriction: a pilot study

The King–Devick test (K–D) is sensitive to the effects of acute sleep deprivation. It remains unclear whether the K–D is sensitive to the effects of chronic partial sleep restriction...

Abnormal Eye Movement Behavior during Reading in Parkinson’s Disease

Purpose : Vision difficulties have been well described in patients with Parkinson’s Disease (PD), but the etiologies underlying PD patients’ difficulties in performing functional tasks like reading are not well understood....

Capturing the Efferent Side of Vision in Multiple Sclerosis: New Data from a Digitized Rapid Number Naming Task

Introduction: Visual function in multiple sclerosis (MS) has been well characterized from an afferent standpoint using low-contrast acuity, optical coherence tomography (OCT) and quality of life (QOL). Compared to...

Abnormal Visual Contrast Acuity in Parkinson’s Disease

Background: Low-contrast vision is thought to be reduced in Parkinson’s disease (PD). This may have a direct impact on quality of life such as driving, using tools, finding objects,...

The Effects of Mild, Acute Hypoxia on Cognitive Performance

Background: The Swedish nuclear power plant Forsmarks Kraftgrupp AB (FKA) reported that they wanted to use a fi re prevention method by reducing the oxygen level down to 15%...

Validation of Strategies to Streamline High and Low Contrast Acuity testing in ALS Subjects

BACKGROUND: Afferent visual system disorders are included in the phenotypic spectrum Amyotrophic Lateral Sclerosis (ALS). High and low contrast visual acuity (HCVA and LCVA) are potential quantitative clinical markers...

Visual Performance Testing in Children with Attention Deficit Hyperactivity Disorder

BACKGROUND: ADHD is the most prevalent pediatric neurodevelopment disorder. In the United States, it is estimated that 5.4 million children 6 and 17 years of age (or 9.5% of...

The King-Devick (K-D) Test of Rapid Eye Movements: A Bedside Correlate of Disability and Quality of Life in MS

OBJECTIVE: We investigated the King-Devick (K–D) test of rapid number naming as a visual performance measure in a cohort of patients with multiple sclerosis (MS). METHODS: In this cross-sectional...

Acute Hypoxic Hypoxia and Isocapnic Hypoxia Effects on Oculometric Features

Introduction: Visual performance impairment after hypoxia is well recognized in military and civilian aviation. The aims of this study were: 1) to assess oculometric features such as blink metrics,...

The Effect of Visual Scanning Exercises Integrated Into Physiotherapy in Patients with Unilateral Spatial Neglect Poststroke: A Matched-Pair Randomized Control Trial

Background: Unilateral spatial neglect (USN) is a visual-perceptual disorder that entails the inability to perceive and integrate stimuli on one side of the body, resulting in the neglect of...

Assessment of Prefrontal Cortex Activity in Amyotrophic Lateral Sclerosis Patients with Functional Near Infrared Spectroscopy

Cognitive impairment in amyotrophic lateral sclerosis (ALS) is associated with cortical changes beyond the motor cortex. The overall goal of this project is to determine if task induced hemodynamic...

Slowing of Number Naming Speed by King-Devick Test in Parkinson’s Disease

Background: The King-Devick (KD) test measures the speed of rapid number naming, and is postulated to require fast eye movements, attention, language, and possibly other aspects of cognitive functions....

Early Detection of Hypoxia-Induced Cognitive Impairment Using the King-Devick Test

Introduction: Hypoxic incapacitation continues to be a significant threat to safety and operations at high altitude. Noninvasive neurocognitive performance testing is desirable to identify presymptomatic cognitive impairment, affording operators...
