Periodic Limb Movements (PLMs) are episodic, involuntary movements caused by fairly specific muscle contractions that occur during sleep and can be scored during nocturnal polysomnography (NPSG). Because leg movements (LM) may be accompanied by an arousal or sleep fragmentation, a high PLM index (i.e. average number of PLMs per hour) may have an effect on an individual's overall health and well...

Individuals who habitually breathe through the mouth are more likely than nasal breathers to have sleep disorders and attention deficit hyperactive disorder. We hypothesized that brain hemodynamic responses in the prefrontal cortex might be different for mouth and nasal breathing. To test this hypothesis, we measured changes in oxyhemoglobin and deoxyhemoglobin in the prefrontal cortex during m...

OBJECTIVE To determine the prevalence of chronic morning headaches (CMH) in the general population and their relationship to sociodemographic characteristics, psychoactive substance use, and organic, sleep, and mental disorders. METHODS A telephone questionnaire was submitted to 18 980 individuals 15 years or older and representative of the general populations of the United Kingdom, Germany, ...

Sleep disturbances are common in many neurodegenerative diseases and may include altered sleep duration, fragmented sleep, nocturia, excessive daytime sleepiness, and vivid dreaming experiences, with occasional parasomnias. Although representing the "gold standard," polysomnography is not always cost-effective or available for measuring sleep disturbance, particularly for screening. Although nu...

OBJECTIVE The purpose of this work was to determine whether, in children with metabolic syndrome and sleep-disordered breathing, metabolic markers separate them from children with metabolic syndrome without sleep-disordered breathing and whether treatment of sleep-disordered breathing with continuous positive airway pressure is associated with an improvement in metabolic derangement. PATIENTS...

OBSTRUCTIVE SLEEP APNEA SYNDROME (OSAS) IS A DISORDER IN WHICH PEOPLE REPETITIVELY STOP BREATHING DURING SLEEP AND HAVE THE NIGHT TIME CONSEQUENCES OF HYPOXEMIA AND SLEEP FRAGMENTATION, and the daytime consequences of sleepiness and cardiovascular comorbidity.1 OSAS which was once thought to be very rare in females, is actually common in them. In an accompanying review,2 we discuss gender-relat...

OBJECTIVE To identify fibromyalgia syndrome in patients with sleep disordered breathing. METHOD We studied 50 patients seeking treatment at a sleep disorder clinic for snoring, apnea and excessive daytime sleepiness. Sleep disordered breathing was diagnosed through the use of polysomnography. To diagnose fibromyalgia syndrome, patients were evaluated in accordance with the criteria establishe...

Last week we publiihed an essay on snoring, its causes, varying degrees of severity, and the types of remedies people have sought. I observed that there is very little literature in scientific and medical journals on snoring and that, untif recently, it was not treated as a medlcsf problem at all. 1 However, this picture is beginning to change due to the recent interest in a breathing disorder ...

Sleep apnea is a common disorder in which breathing is briefly and repeatedly interrupted during sleep. There are three types of sleep apnea; Central sleep apnea, Obstructive sleep apnea, and Mixed or Complex sleep apnea. Obstructive sleep apnea (OSA) being more common, is characterized by obstruction of the upper airway and subsequently cessation of breathing during sleep. Various epidemiologi...

background and objective : obstructive sleep apnea (osa) syndrome is a kind of sleep-related disorder with complex features and may lead to daytime sleepiness. this study aimed to find the differences between smokers and non-smokers regarding the parameters of polysomnography. materials and methods : this was a cross-sectional study conducted on consecutive patients referred to a sleep lab to p...
