The association between these two conditions has been contradictory. The aim of this study is to analyze the association between these two non-motor symptoms. Methods: Consecutive subjects with Parkinson’s disease attending the Movement Disorders Outpatient Clinic were included. The presence of ICDs was assessed using the Questionnaire for Impulse Control Disorders Rating Scale. RBD was diagnosed by an overnight, single night polysomnography. Results: Fifty-five consecutive subjects with Parkinson’s disease were included. The prevalence of ICDs and related behaviors was 23.6% (ICD in 14.5% and related behaviors in 9.1%). RBD was diagnosed in 47.2% of the patients. No differences were found in the frequency of ICDs and related behaviors when comparing subjects with and without RBD (23% versus 24.1%, p = 0.926, respectively). Conclusion: No association between the presence of RBD and the frequency of ICDs in subjects with Parkinson’s disease was found.展开更多

Spontaneous, periodically modulated, neurogenic bursts of non-purposive movements are a universal feature of larval and prenatal behavior, which in endothermic animals （i.e. birds and mammals） continue to occur periodically throughout life. Since the entire body musculature is involved in ever-shifting combinations, it is proposed that these spontaneously active periods be designated as ＇rapid-BODY-movement＇ （RBM） sleep. The term ＇rapid-EYE- movement （REM） sleep＇, characterized by attenuated muscle contractions and reduced tonus, can then be reserved for sleep at later stages of development. Mature stages of development in which sustained muscle atonia is combined with ＇paradoxical arousal＇ of cortical neuronal firing patterns indisputably represent the evolutionarily most recent aspect of REM sleep, but more research with ectothermic vertebrates, such as fish, amphibians and reptiles, is needed before it can be concluded （as many prematurely have） that RBM is absent in these species. Evidence suggests a link between RBM sleep in early development and the clinical condition known as ＇REM sleep behavior disorder （RBD）＇, which is characterized by the resurgence of periodic bouts of quasi-fetal motility that closely resemble RBM sleep. Early developmental neuromotor risk factors for RBD in humans also point to a relationship between RBM sleep and RBD.展开更多

PD is classically characterized by motor features, although patients may also experience non-motor symptoms. Sleep disturbances, such as rapid eye movement (REM) behavior disorder (RBD), are common in patients with PD and may precede onset of PD. Methods: Data was collected on patients with PD (358 subjects)in a movement disorders clinic at a safety net hospital. In this retrospective database analysis, the association of PD complications with age of onset was evaluated using chi-square tests and logistic regression. Results: Of the PD complications analyzed, there was a significant difference in sleep disturbances by age. Among the 358 PD patients, 120 individuals (33.5%) had information regarding the presence or absence of sleep disturbances. There was a significant difference between the early (onset < 50) and later onset (≥50) groups (p = 0.03) with the odds of having a sleep disorder for the early group 1.6 times that of the late group. Those subjects with siblings who also had PD had 2.0 times the odds of having a sleep disorder compared those without (p = 0.02). Conclusion: Non-motor symptoms such as sleep disorders are a useful predictor of early onset PD. Genetic components of PD impact both motor and non-motor aspects of the disease.展开更多
