introduction: information on the sleepiness and sleep quality is limited for asians. this study was conducted to determine the prevalence of sleepiness and sleep quality among the adult population in iran. materials and methods: this is a descriptive and explorative design study in which 1100 participants randomly selected from the kerman city population in south –east of iran. using two questi...

OBJECTIVES The relationship between anxiety and obstructive sleep apnea (OSA) has not been well studied. We evaluated the factors associated with anxiety and whether anxiety is related to quality of life (QoL) independently of depression in OSA patients. METHODS Data were collected from adults with newly diagnosed, untreated OSA. The State-Trait Anxiety Inventory-State Scale (STAI-S), the Bec...

OBJECTIVE We aimed to investigate the effect of ropinirole on excessive daytime sleepiness (EDS) and depression in Parkinson's disease (PD) with a large population. METHODS We conducted a cross-sectional observational study at nine hospitals in Korea between April 24, 2013, and April 22, 2015. We analyzed the demographic and clinical features, other medical history, history of antiparkinsonia...

The purpose of the present study was to identify risk factors for and prevalence of excessive daytime sleepiness and associations between demographic factors, obesity and metabolic syndrome criteria and excessive daytime somnolence (EDS). A descriptive and analytical study was conducted among 508 volunteers in primary health care centers in western Anatolia, Turkey. The data were obtained using...

OBJECTIVES To investigate the impact of sleep disturbances on Parkinson's disease (PD) clinical motor subtypes and disease-related disability in a multicentre setting. METHODS We report a cross-sectional relationship between sleep-related symptoms and clinical motor subtypes (tremor dominant (TD); intermediate; postural instability and gait disturbances (PIGDs)) identified in a multicentre st...

BACKGROUND Continuous positive airway pressure (CPAP) for symptomatic obstructive sleep apnoea (OSA) improves sleepiness and reduces vascular risk, but such treatment for the more prevalent, minimally symptomatic disease is contentious. METHODS This multicentre, randomised controlled, parallel, hospital-based trial across the UK and Canada, recruited 391 patients with confirmed OSA (oxygen de...

Excessive daytime sleepiness (EDS) is a major health concern in geriatric patients. EDS affects quality of life, daytime function, and mortality. The Epworth Sleepiness Scale (ESS) is a standard tool for the assessment daytime sleepiness, but the feasibility of the ESS has never been investigated in elderly subjects. We applied the ESS to a random sample of geriatric in-hospital patients. The a...

OBJECTIVES To assess the reliability of the Epworth Sleepiness Scale (ESS), Daytime Sleepiness Scale (DSS), Chalder Fatigue Scale (CFS), and Krupp's Fatigue Severity Scale (KFSS) in patients with myotonic dystrophy type 1 (DM1). METHODS In total, 27 patients with DM1 were administered the questionnaires on two occasions, with a 2 week interval. Internal consistency and test retest reliability...

BACKGROUND It is well known that the sleeping position influences the rate of apnea-hypopnea events; however, whether events in one position may have more influence on daytime sleepiness than events in another position has not been thoroughly investigated. OBJECTIVES We retrospectively examined the relationship between the body position-specific apnea-hypopnea index (AHI) and daily sleepiness...

ABSTRACT Type 2 diabetes (T2D) is an independent risk factor for sleep breathing disorders. However, it is unknown whether T2D affects daily somnolence and quality of sleep independently of the impairment of polysomnographic parameters. MATERIAL AND METHODS A case-control study including 413 patients with T2D and 413 non-diabetic subjects, matched by age, gender, BMI, and waist and neck circu...
