It is a matter of debate whether patients with primary insomnia require a polysomnographic examination in order to exclude specific sleep disorders such as sleep apnea syndrome (SAS) or periodic limb movements (PLM). Using a prospective design, we investigated the prevalence of organic sleep disorders by means of polysomnography (PSG) in a series of(More)
Somatoform disorders (SD) are common medical disorders with prevalence rates between 3.5% and 18.4%, depending on country and medical setting. SD as outlined in the ICD-10 exhibits various biological, social, and psychological pathogenic factors. Little is known about the neural correlates of SD. The aims of this meta-analysis are to identify neuronal areas(More)
Sleep deprivation was found to exert complex effects on affective dimensions and modalities of pain perception both in healthy volunteers and patients with major depression. Considering multifaceted links between mood and pain regulation in patients with chronic somatoform pain, it is intriguing to study sleep deprivation effects for the first time in this(More)
Although gender differences in pain and analgesia are well known, it still remains unclear whether men and women vary in response to multimodal pain treatment. This study was conducted to investigate whether men and women exhibited different outcomes after an intensive multimodal pain treatment program. The daily outpatient program consisted of individual(More)
OBJECTIVE Given the prevalence and costs of somatoform disorders, it is important to identify and adequately treat these patients as early as possible. Instruments assessing experiences, perceptions, and behaviors of somatoform disorders are rare. In this study we evaluated the structure and validity of the German version of the Health Attitude Survey(More)
BACKGROUND The Regensburg Insomnia Scale (RIS) is a new self-rating scale to assess cognitive, emotional and behavioural aspects of psychophysiological insomnia (PI) with only ten items. A specific purpose of the new scale is the evaluation of the outcome of insomnia- specific cognitive behaviour therapy (CBT-I). METHODS Internal consistency of the RIS(More)
Current studies suggest dysfunctional emotional processing as a key factor in the aetiology of temporomandibular disorder (TMD). Investigating facial emotion recognition (FER) may offer an elegant and reliable way to study emotional processing in patients with TMD. Twenty patients with TMD and the same number of age-, sex- and education-matched controls(More)
The aim of this study is to determine parameters which influence 6-month compliance of continuous positive airway pressure therapy (CPAP) in patients with obstructive sleep apnea syndrome (OSAS). This prospective study investigated 73 patients (24 females) with OSAS and medical indication for CPAP therapy: age 55.1 ± 11.5 years, body mass index (BMI) 30.8 ±(More)
OBJECTIVE This review gives an overview about the consequences of sleep deprivation (SD) on pain perception and discusses the bi-directional relation between sleep and pain. METHODS A MEDLINE research (16.7.2010) for the terms "sleep" AND "pain" AND ("sleep deprivation" OR "sleep loss" OR "sleep restriction" OR "sleep interruption") showed 177 hits. Only(More)
BACKGROUND There is strong evidence indicating an interaction between sleep and pain. However, the size of this effect, as well as the clinical relevance, is unclear. Therefore, this meta-analysis was conducted to quantify the effect of sleep deprivation on pain perception. METHODS A systematic literature search was conducted using the electronic(More)
