Sleep abnormalities are frequently found in Parkinson’s disease (PD). However, it is unclear if they are present from the initial stages of PD. We thus aimed to assess sleep disturbances in newly diagnosed PD patients. We investigated 20 untreated PD patients using the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI) and the PD(More)
This study evaluated the effects of ropinirole prolonged-release (RPR) in comparison with ropinirole immediate-release (RIR) on sleep-related disorders in Parkinson disease (PD).Thirty-three PD patients (aged 62.5 [SD, 8] years; PD duration, 9 [SD, 4] years) were evaluated on a stable dose of RIR and 5 to 13 weeks after switch to the closest possible dose(More)
OBJECTIVE Patients with idiopathic rapid eye movement sleep behaviour disorder (RBD) are at substantial risk for developing Parkinson's disease (PD) or related neurodegenerative disorders. Speech is an important indicator of motor function and movement coordination, and therefore may be an extremely sensitive early marker of changes due to prodromal(More)
OBJECTIVES Narcolepsy with cataplexy is associated with a loss of hypocretin. The question is, if there is an autoimmune or neurodegenerative process selectively killing the hypothalamic hypocretin-containing neurons or if these cells survive but fail to produce hypocretin. To support one of these hypothesis we aimed to detect structural changes in the(More)
Narcolepsy-cataplexy (N-C) is a focal neurodegenerative disease with a genetic predisposition and autoimmune etiology; the pathogenesis of narcolepsy without cataplexy (Nw/oC) is less clear. One hundred and forty eight patients underwent clinical face-to face interviews, polysomnography, multiple sleep latency testing and HLA-DQB1*0602 typing. The cohort(More)
OBJECTIVE The aim of the study is to compare the course and severity of narcolepsy in relation to different ages at the disease onset. METHODS Clinical interviews with the completion of the Stanford questionnaire, Epworth Sleepiness Scale (ESS) and Multiple Sleep Latency Test (MSLT) were evaluated in 105 patients (44 males, 61 females, mean age(More)
BACKGROUND Wilson's disease (WD) is an autosomal recessive inherited disease with copper accumulation; neurodegeneration is associated with dopaminergic deficit. The aim of the study is to verify sleep co-morbidity by questionnaire and objective sleep examinations (polysomnography, multiple sleep latency test). METHODS fifty-five patients with WD (22(More)
BACKGROUND Narcolepsy with cataplexy (NC) differs from narcolepsy without cataplexy (NwoC) in the cerebrospinal fluid levels of hypocretin. Since hypocretin is known to regulate not only wakefulness but also eating behaviour, we decided to compare the two entities for body mass index (BMI) and the presence of obesity. METHODS Clinical data on patients(More)
BACKGROUND AND PURPOSE The second version of the International Classification of Sleep Disorders suggests narcolepsy with cataplexy can be diagnosed on history alone. PATIENTS Five patients with a history supportive of narcolepsy/cataplexy. METHOD Case review following clinical investigation. RESULTS None of the five patients had a diagnosis of(More)
OBJECTIVE Based on the clinical observation that patients suffering from narcolepsy with cataplexy (NC) have cataplectic attacks when they experience positive emotions, it is therefore hypothesised that the abnormal processing of external emotional input through the limbic system, or motor dysregulation induced by emotions, takes place during these(More)
