Daytime performance changes were examined during chronic sleep restriction or augmentation and following subsequent recovery sleep. Sixty-six normal volunteers spent either 3 (n = 18), 5 (n= 16), 7 (n = 16), or 9 h (n = 16) daily time in bed (TIB) for 7 days (restriction/augmentation) followed by 3 days with 8 h daily TIB (recovery). In the 3-h group, speed (mean and fastest 10% of responses) o...

AIM Characterize pharmacokinetics, pharmacodynamics, and safety/tolerability of USL261 in geriatric adults to inform its potential for treating bouts of increased seizure activity. METHODS Phase 1, randomized, double-blind, 2-way crossover study in healthy geriatric (≥65years; n=18) and non-geriatric (18-40years; n=12) adults evaluated single USL261 doses (2.5 and 5.0mg) administered intranas...

Toxoplasma gondii is known to induce specific behavioural changes in its intermediate hosts. This is usually considered to be an evolutionary adaptation aimed to increase the probability of transmission of the parasite into its definitive host, the cat, by predation. In rodents an increase of reaction time as well as many other specific behavioural patterns have been observed. Here we report th...

PURPOSE In response to mission imperatives, transport aircrews must often sleep at inappropriate circadian times resulting in inadequate sleep. This study was undertaken to determine whether either melatonin or zopiclone could facilitate early circadian sleep, and to assess whether either of these medications would result in a psychomotor performance decrement which would preclude their use in ...

AIM To assess if there is deterioration in mental and psychomotor performance during 24-hour voluntary fluid intake deprivation. METHODS A battery of computer generated psychological tests (Complex Reactionmeter Drenovac-series) was applied to 10 subjects to test light signal position discrimination, short-term memory, simple visual orientation, simple arithmetics, and complex motor coordinat...

BACKGROUND Obstructive sleep apnea (OSA) is a highly prevalent disorder with considerable morbidity and mortality. Vigilance and attentiveness are often impaired in OSA patients. In occupational medicine settings, subjective reports of sleepiness are notoriously inaccurate, making the identification of objective measures of vigilance potentially important for risk assessments of fitness for dut...

BACKGROUND Opioids can impair psychomotor performance, and driving under the influence of opioids is associated with an increased risk of accidents. The goals of this study were i) to determine the prevalence of opioids (heroin, morphine, codeine, methadone and tramadol) in Spanish drivers and ii) to explore the presence of opioids, more specifically whether they are used alone or in combinatio...

Objective: The present study aimed at evaluating the effect of Panax Ginseng on malondialdehyde (MDA) serum levels during eustress on healthy volunteers. Method: In this study, 65 healthy volunteers were recruited from students of a medical school, with the mean age of 22.61±3.63 years. The volunteers were divided into 2 groups: Group A included 35 participants who were treated by Panax Ginseng...

The role of Delta(9)-tetrahydrocannabinol (THC) in driver impairment and motor vehicle crashes has traditionally been established in experimental and epidemiological studies. Experimental studies have repeatedly shown that THC impairs cognition, psychomotor function and actual driving performance in a dose related manner. The degree of performance impairment observed in experimental studies aft...
