Four male patients and one female patient of a new family with Joseph disease are reported. Their disease was characterized by autosomal dominant inheritance, bulging eyes, rigidity and spasticity of the lower extremities, dystonia, and bradykinesia. Cerebrospinal fluid homovanillic acid level was markedly reduced. Levodopa improved dystonia. Magnetic resonance imaging revealed mild atrophy of the frontal lobe and the cerebellum and marked atrophy of the lenticular nucleus and the brain stem. Polysomnographic studies revealed non-rapid eye movement stage central type sleep apnea syndrome. This is the first report using magnetic resonance imaging and sleep apnea studies of Joseph disease.

Parkinson's disease is a progressive disorder of the central nervous system. Degeneration of the dopaminergic neurons is the main cause of the disease. The basic symptoms of Parkinson's disease are bradykinesia, rigidity and resting tremor. Disturbances of the autonomous nervous system, depression, dementia and sleep disorders are common, too. People with Parkinson's disease suffer from insomnia, excessive daytime sleepiness, "sleep attacks", nightmares, REM sleep behaviour disorder, periodic limb movement in sleep, restless legs syndrome and sleep apnea syndrome. The main cause of sleep disorders in Parkinson's disease are age-connected changes in sleep architecture, disturbances of neurotransmission, movement disturbances in sleep, medications and concomitant diseases. The authors present the current state of knowledge on sleep disorders in Parkinson's disease, especially, the role of dopaminergic therapy, methods of diagnostics and treatment as well as the influence of sleep disturbances on patient's quality of life.

Parkinson's disease (PD) is the second most common neurodegenerative disorder, characterized by resting tremor, rigidity, bradykinesia and postural instability, and is associated with non-motor features, including sleep abnormalities. The high prevalence of excessive daytime sleepiness and snoring in PD patients has led to the suggestion that sleep disordered breathing (SDB) is more common in these individuals than in normal subjects. We aimed to review the literature on SDB prevalence and its clinical repercussions in PD. A PubMed search was performed to identify controlled studies, published from January 1990 through October 2012, which addressed the prevalence of SDB diagnosed by polysomnography in idiopathic PD. From the seven studies included, five reported similar or lower prevalence of SDB in patients when compared to healthy age-matched controls. Two studies reported less oxyhemoglobin desaturation during sleep among patients. These results did not support the idea that PD patients are at increased risk of SDB and indicate that they may not present significant hypoxemia. The prevalence of obstructive sleep apnea syndrome and the long-term outcomes of disordered breathing events during sleep have not been adequately studied in PD.

Parkinson's disease (PD) is the second most common neurodegenerative disorder, ranking only behind Alzheimer's disease and affecting 2% of the population over the age of 65. Pathophysiologically, PD is characterized by selective degeneration of the dopaminergic neurons of the substantia nigra pars compacta (SNpc) and striatal dopamine depletion. Patients may also exhibit mild-to-severe degeneration of other central and peripheral nervous tissues. The most dramatic symptoms of the disease are profound dopamine-responsive motor disturbances, including bradykinesia, akinesia, rigidity, resting tremor, and postural instability. PD patients commonly present with debilitating non-motor symptoms, including cognitive impairment, autonomic nervous system dysfunction, and sleep disturbance. Of these, sleep disturbance is the most consistently reported, and likely represents a disorder integrative of PD-related motor impairment, autonomic nervous system dysfunction, iatrogenic insult, and central neurodegeneration. The pathophysiology of PD may also indirectly disrupt sleep by increasing susceptibility to sleep disorders, including sleep disordered breathing, periodic limb movements, and REM behavior disorder. In this review, we will discuss these systems representing a multifactorial etiology in PD sleep disturbance.
