We report on a case of nocturnal headache attacks fulfilling the criteria for hypnic headache syndrome. Using an overnight polysomnography, one nocturnal headache attack was captured during the REM phase of sleep. Quality of sleep was poor with desaturation episodes. However, the hypnic headache attack was not associated with oxygen desaturation. This additional case supports the view of a rela...

Muscle pain occurs in various neuromuscular disorders with characteristic physiological or biochemical abnormalities. There is, however, a group of patients in whom there is no clear physiological or structural basis for their pains. This syndrome has been called fibrositis or fibromyalgia. Sleep abnormalities have been reported in some of these patients, but have not been confirmed by others. ...

Polysomnographic findings were compared with data obtained subsequently from home documented monitoring in order to study the diagnostic value of both techniques. Polysomnography was performed in 1274 infants born prematurely and in 422 patients admitted because of apparent life threatening events (ALTEs). In 72 of the infants, home documented monitoring of the cardiorespiratory pattern, includ...

Obstructive sleep apnea (OSA) is a common sleep disorder characterized by repetitive episodes of apnea and hypopnea during sleep. The symptoms include excessive daytime sleepiness, non-refreshing sleep, daytime fatigue, and decreased concentration, which may cause marked impairment in social or occupational functioning. In addition, the patients with OSA were shown to have an increased risk of ...

When employing between-infant designs young infants' looking style is related to their development: Short looking (SL) infants are cognitively accelerated over their long looking (LL) peers. In fact, looking style is a within-infant variable, and depends on infant i's look distribution over trials. For the paired array setting, a model is provided which specifies the probability, π i ∈ [0, 1], ...

OBJECTIVE To validate a cardiorespiratory polygraphy system (BITMED NGP 140) by comparing it to conventional polysomnography in the diagnosis of sleep apnea-hypopnea syndrome. PATIENTS AND METHODS Polysomnography and cardio-respiratory polygraphy were performed simultaneously on 103 consecutive patients referred because of suspected sleep apnea-hypopnea syndrome. The Bland and Altman method a...

Periodic limb movements are short movements of the legs that can lead to low sleep quality in the general population. Currently, the gold standard to measure periodic limb movements for diagnostic purposes is polysomnography. This is an expensive technique that requires specially fitted laboratories and specialized personnel. In this paper we explore the use of commercial, off-the-shelf acceler...

Sleep specialists are frequently referred adults with epilepsy to evaluate their sleep/wake complaints, sometimes to determine whether their paroxysmal nocturnal behaviors are epileptic or not. Many patients with epilepsy have at least one parasomnia (some more than one), and the sleep specialists are often asked to differentiate and treat these. Sleep specialists review which primary sleep dis...

STUDY OBJECTIVES To evaluate the accuracy and practicality of the Apnea Risk Evaluation System (ARES; Advanced Brain Monitoring; Carlsbad, CA), a limited-channel system for diagnosing sleep apnea/hypopnea in the home. DESIGN Prospective randomized study with blinded analysis. SETTINGS Two independent, community-based, sleep-disorders centers and the participants' homes. PARTICIPANTS Two h...
