This is the first study to analyze variations in time estimation during 60 h of sleep deprivation and the relation between time estimation performance and the activation measures of skin resistance level, body temperature, and Stanford Sleepiness Scale (SSS) scores. Among 30 healthy participants 18 to 24 years of age, for a 10-s interval using the(More)
Obstructive sleep apnea (OSA) is a disorder characterized by repeated episodes of complete (apneas) or partial (hypopneas) cessations of breathing while sleeping. While continuous positive airway pressure (CPAP) treatment is commonly chosen to treat OSA, various conservative behavioral therapies are also used, particularly in patients unable to tolerate or(More)
Sleep disturbances play an important role in the exacerbation of pain and other troubling symptoms reported by patients with fibromyalgia (FM). The objective of this trial was to analyze the efficacy of a cognitive-behavioral therapy for insomnia (CBT-I) versus a sleep hygiene (SH) education program at improving sleep and other clinical manifestations in(More)
The present study analyses the variations of the skin resistance level (SRL) during 48 h of total sleep deprivation (TSD) and its relationship to body temperature, self-informed sleepiness in the Stanford Sleepiness Scale (SSS), and reaction time (RT). All of the variables were evaluated every 2 h except for the SSS, which was evaluated every hour. A total(More)
BACKGROUND In 1998, we revealed a sequence departing from prenatal growth restraint in girls and evolving, through precocious pubarche (PP) in mid-childhood, towards anovulatory and hyperinsulinaemic hyperandrogenism. The latter condition fulfilled the criteria for the diagnosis of polycystic ovary syndrome (PCOS), which was then defined independently of(More)
OBJECTIVES Fibromyalgia (FM) is a chronic pain syndrome associated with adverse symptoms of cognitive, behavioural, and emotional dysfunction. Accumulating evidence supports the notion that sleep dysfunction, which affects almost all FM patients, has a reciprocal influence on pain. Yet, little is known about the relationship between sleep and other FM(More)
A study was carried out in which age and gender differences were studied in the performance of an empty interval production task. The duration of these intervals was 10 s, 1 and 5 min. The sample was made up of 140 subjects, half male and half female, in seven different age groups from 8 to 70 years old. The age range permitted us to identify when(More)
Cognitive deficits in fibromyalgia may be specifically related to controlled processes, such as those measured by working memory or executive function tasks. This hypothesis was tested here by measuring controlled temporal preparation (temporal orienting) during a response inhibition (go no-go) task. Temporal orienting effects (faster reaction times for(More)
OBJECTIVES The prevalence of fibromyalgia (FM) is much lower in men than in women. Therefore, current knowledge about this chronic pain syndrome emerged mainly from research on women. The aim of the present study was to compare clinical symptoms and sleep parameters between male and female FM patients. METHODS Forty FM patients (18 men and 22 women) aged(More)
The prevalence of fibromyalgia (FM) in males is much lower than in women. Thus, current knowledge about the syndrome has been developed from research with women. The aim of the present study is to analyze whether FM manifestations differ as a function of sex. Two clinical groups with FM (21 males and 21 women) and a control group of healthy men (n= 21)(More)
