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...
Vision and vision-related outcome measures in multiple sclerosis
Visual impairment is a key manifestation of multiple sclerosis. Acute optic neuritis is a common, often presenting manifestation, but visual deficits and structural loss of retinal axonal and neuronal...
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...
Residency Training: The King-Devick Test and sleep deprivation: Study in pre- and post-call neurology residents
Objective: The current study investigates the effect of sleep deprivation on the speed and accuracy of eye movements as measured by the King-Devick (K-D) test, a 1-minute test that...
