Visual evoked potential (VEP) abnormality is widely used as an objective indication of visual pathophysiology in the diagnosis of multiple sclerosis. One major limitation of this test is that VEP abnormality is not specific to multiple sclerosis. In an attempt to explore ways of making the VEP test more specific, changes were measured in VEPs caused by superimposing upon the VEP stimulus either...

Background: Fatigue is one of the most prevalent and debilitating complications of cancer and its treatments. Patients with radiotherapy experience some degrees of fatigue. Complementary medicine methods, have reduced the complications of treatments in many disorders. Accordingly, the present study was conducted with the aim of comparing the effect of aromatherapy by inhalation and massage on R...

OBJECTIVE A subgroup of patients with Chronic Fatigue Syndrome (CFS) has cognitive impairments, reflected by deviant neuropsychological test performance. However, abnormal test scores can also be caused by suboptimal effort. We hypothesized that worse neuropsychological test performance and underperformance were related to each other and to a smaller reduction in fatigue, functional impairments...

PURPOSE/OBJECTIVES To test whether sleep disturbance mediates the effect of pain on fatigue. DESIGN Cross-sectional. SETTING Radiation therapy clinic, oncology ambulatory clinic, and inpatient oncology unit in an urban teaching hospital. SAMPLE 84 patients with cancer with multiple primary diagnoses who were experiencing pain. Fifty-three percent were female and 92% were Caucasian, with a...

Automatic systems for estimating operator fatigue have application in safety-critical environments. A system which could estimate level of fatigue from speech would have application in domains where operators engage in regular verbal communication as part of their duties. Previous studies on the prediction of fatigue from speech have been limited because of their reliance on subjective ratings ...

BACKGROUND Fatigue is common and disabling in multiple sclerosis, yet its physiologic substrates remain poorly defined. The aim of this study was to determine the relationship between fatigue and an objective measure of alertness in MS patients. METHODS This study enrolled 49 consecutive MS clinic patients at two academic hospitals in Toronto. Alertness was assessed with the psychomotor vigil...

The influence of frequency and intensity in Min dialect on maximum vocal performance has not been investigated. The purposes of this study are (1) to investigate the physiological frequency and intensity ranges of the tonal dialect of Min, and (2) to compare the physiological frequency and intensity ranges of Min to those of nontonal languages. The subjects were 40 normal Taiwanese adults. All ...

INTRODUCTION Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with a progressive and rapid course. Fatigue and depression are common among ALS patients. The aim of this study was to determine the relationship between depression and fatigue in Iranian ALS patients. METHODS In this 2012 cross-sectional study, 40 ALS patients, including 22 females and 18 males, were selec...
