Sleep benefit in Parkinson's disease is characterized by restoration of mobility upon awakening from sleep and prior to drug intake. With this study, we aimed at assessing clinical and nocturnal sleep correlates of this phenomenon. We recorded motor and non-motor symptoms in 131 Parkinson patients with and without sleep benefit, as assessed by questionnaires. Polysomnography recordings were per...

To evaluate the effect of intermittent hypoxemia on neuropsychological functioning, neuropsychological tests were administered to 14 sleep apnea patients, a control group of 10 patients with other disorders of excessive somnolence, and another control group of 14 healthy volunteers. The sleep disorder groups were matched on two measures of sleepiness. It was found that sleep apnea patients perf...

Patients with the sleep apnoea/hypopnoea syndrome (SAHS) have impaired daytime function with demonstrable sleepiness and impaired cognition. The hypothesis that brief arousals from sleep cause these daytime impairments was tested. One hundred and fifty patients with sleep disordered breathing were studied prospectively, comparing overnight polysomnography with daytime measures of objective slee...

The occurrence of slow wave sleep within spontaneously initiated daytime sleep episodes was studied to examine hypothesized associations with prior wakefulness and circadian factors. There was a strong relationship between measures of slow wave sleep and the proximity of sleep episodes to the maximum of body core temperature. Those sleep episodes that began within 4 hours of the maximum in body...

Seventeen adult male and female subjects participated in a clinical trial using an open-label trial to evaluate the effectiveness of pyrroloquinoline quinone (PQQ) on stress, fatigue, quality of life and sleep. They ingested 20 mg of PQQ daily for 8 weeks. Changes in stress, fatigue, quality of life measures and sleep were evaluated using various inventories and questionnaires. For example, the...

Assessed the relation of behavioral codes of quiet versus active sleep state to neonatal health status in 62 very low birth weight preterm neonates. Sleep sessions (12 min) were coded for percentage time in active versus quiet sleep at 33, 34, and 35 weeks conceptional age. ECG was monitored during each sleep session to derive measures of heart rate, heart rate variability, and an index of card...

OBJECTIVE The Child Behavior Checklist is sometimes used to assess sleep disturbance despite not having been validated for this purpose.

METHOD Participants were 122 youth (61% female, aged 7 through 17 years) with anxiety disorders (19%), major depressive disorder (9%), both anxiety...

METHODS Data were derived from Finnish Helsinki Health Study postal questionnaires administered in 2000-2002 (n = 7777, response rate 67%). The measures were the 4-item Jenkins Sleep Questionnaire (JSQ) on ...
