Sleep dysfunction in Parkinson's disease.

The frequency of sleep complaints in patients with Parkinson's disease (PD) is estimated to be between 60-90% and a variety of either disease-related or secondary mechanisms and the dopaminergic treatment itself contributes to the development of different sleep disturbances. These comprise slight, fragmented sleep with increased number of arousals and awakenings, and PD-specific motor phenomena such as nocturnal immobility, rest tremor, eye-blinking, dyskinesias, and other phenomena such as periodic and nonperiodic limb movements in sleep, restless legs syndrome, fragmentary myoclonus, and respiratory dysfunction in sleep. Depression and hallucinations/psychosis further complicate the picture. The incidence of REM sleep behavior disorder (RBD) with nightmares and violent behavior is increased in PD and may occur as a preclinical disease-related symptom. A careful sleep history of patients and their partners, polysomnograms when necessary, motor and psychiatric assessments should precede individual treatment strategies, which include adjusting dopaminergic daytime treatment, benzodiazepines for RBD, reduction of anticholinergic drugs, and, if necessary, clozapine for nocturnal psychosis.

[Behavioral impairments in Parkinson's disease].

Behavioral impairments in parkinsonian patients include agitation, hypersexuality, stereotypic movement, pathological gambling, abuse of antiparkinsonian drugs, REM sleep behavioral disorder, and restless legs syndrome. Dementia, psychoses, and emotional disorders, such as depression and anxiety/panic disorder, also impair behavior. Symptoms may be produced by dysfunction of the central nervous system, medication, and/or the psychosocial problems associated with Parkinson's disease. Treatment therefore should be based on the cause of the symptoms seen. In some cases, the reduction or change of antiparkinsonian drugs, or both, may be effective. Treatment of the motor symptoms of Parkinson's disease, including motor fluctuations, may reduce the risk of panic attacks being evoked in the 'off' period. Use of antidepressants, sedatives, and neuroleptics may often be effective. Physicians should identify the causes of the symptoms of behavioral impairment and select appropriate treatments.

Parasomnias.

This article presents four examples of parasomnia activity. Sleepwalking, sleep terror, and rhythmic movement disorder all occur more commonly in children; however, they can persist into adulthood. REM behavior disorder frequently occurs in elderly patients with neurologic lesions. The sleep stage associations of the different disorders differ. Two of the disorders, sleepwalking and sleep terrors, have a clear association with stage 3/4 sleep, and REM behavior disorder occurs in REM sleep. Rhythmic movement disorder episodes can present solely in REM sleep but more typically occur in light non-REM sleep, and there are usually voluntary episodes during wakefulness.

REM behavior disorder associated with epileptic seizures.

Reported is the association of REM behavior disorder (RBD) with late-onset, sleep-related, tonic-clonic seizures in two elderly men. In each patient, RBD preceded the onset of seizures by several years. The authors hypothesize that REM sleep disruption may facilitate seizure occurrence.

Sleep-related non epileptic motor disorders.

Sleep-related non epileptic motor disorders represent a frequent but often neglected or trivialized source of neurological disability. In recent decades, the widespread adoption of videopolygraphic techniques has better characterized already known nosographic entities and described a bewildering variety of previously unrecognized clinical entities (such as REM sleep behaviour disorder, sleep-related eating disorder, benign neonatal sleep myoclonus, facio-mandibular myoclonus during sleep, fragmentary hypnic myoclonus, propriospinal myoclonus at the wake-sleep transition, rhythmic feet movements during sleep, etc). The scope of the neurophysiological investigations of sleep related disorders has therefore been much expanded. However, advances in the semeiology and clinical description of sleep-related movement disorders has rarely been matched by adequate understanding of the underlying pathophysiological mechanisms, or by major advances in treatment. The main sleep-related motor disorders are described here, following the only classification currently available, e. g. that offered by the International Sleep Disorders Classification of the American Sleep Disorders Association, which is more a classification of diseases of sleep than of movement disorders. The increasing use of functional neuroimaging in vivo and of updated neurophysiological and molecular techniques in man and in the experimental animal will hopefully lead to a better understanding of these disorders in terms of pathophysiology of disordered motor control.

[Relationship of changes in sleep architecture and cognitive function in patients with obstructive sleep apnea syndrome].

OBJECTIVES: To explore the relationship between sleep architecture changes and cognitive impairment in patients with obstructive sleep apnea syndrome (OSAS). METHODS: Thirty-six patients with OSAS and 18 controls were administered polysomnography and neuropsychological tests of visual regeneration, digital symbol, comprehensive memory and digital span. RESULTS: Performances on the visual regeneration test and digital symbol test in patients with OSAS were impaired significantly compared with the control group (P < 0.01). Patients' performance on the visual regeneration test was significantly associated with slow wave sleep duration (r = 0.423, P < 0.05) and that on the digital symbol test was significantly associated with REM sleep duration (r = 0.378, P < 0.05). CONCLUSIONS: Slow wave sleep and REM sleep derivation may play a role in the cognitive impairment in patients with OSAS.

REM sleep behaviour disorder in Parkinson's disease: a questionnaire-based study.

The aim of the study was to determine the clinical frequency and features of REM sleep behaviour disorder (RBD) in a large population of Parkinson's disease (PD) patients using defined diagnostic criteria both for RBD and PD. Six trained neurologists used a semistructured questionnaire based on ICSD-R diagnostic criteria for RBD to evaluate 200 PD patients and their caregivers. Interobserver reliability for the diagnosis of RBD was "substantial" (Kappa 0.65). Five patients were excluded from the study because of an MMSE lower than 25. The demographic and PD clinical features were compared in the clinically defined RBD group and in those without RBD (NRBD). Then the RBD features during the last year were analysed in the affected group. Out of 195 patients, 66 fulfilled the ICSD-R criteria for RBD; 62 patients reported RBD during the last year (frequency 31.8%). RBD features: two or more episodes per week in 35.5%; upper limb movements in 87%; lower limb movements in 79%; vocalisations during events in 85%. RBD onset was before PD in 27% of patients; 69% of the RBD group had injured themselves or their caregivers during sleep. According to multivariate analysis, RBD was associated with male gender, age and PD duration. Brief training and the use of a semistructured questionnaire may help the neurologist in dealing with sleep disturbances in PD patients. The search for RBD symptoms in PD is highly recommended, especially in patients with a long disease duration, the risk of sleep-related injuries being high.

Sleep violence--forensic science implications: polygraphic and video documentation.

During the past century, infrequent, anecdotal reports of sleep-related violence with forensic science implications have appeared. Recent rapid developments in the field of sleep-disorders medicine have resulted in greater understanding of a variety of sleep-related behaviors, and formal sleep-behavior monitoring techniques have permitted their documentation and classification. Sleep-related violence can be associated with a number of diagnosable and treatable sleep disorders, including (1) night terrors/sleepwalking, (2) nocturnal seizures, (3) rapid eye movement (REM) sleep-behavior disorder, (4) sleep drunkenness, and (5) psychogenic dissociative states occurring during the sleep period. Potentially violent automatized behavior, without consciousness, can and does occur during sleep. The violence resulting from these disorders may be misinterpreted as purposeful suicide, assault, or even homicide. Sleep-related violence must be added to the list of automatisms. A classification system of both waking and sleep-related automatic behavior is proposed, with recommendations for assessment of such behavior.

Combination of 'idiopathic' REM sleep behaviour disorder and olfactory dysfunction as possible indicator for alpha-synucleinopathy demonstrated by dopamine transporter FP-CIT-SPECT.

REM sleep behaviour disorder (RBD) and olfactory dysfunction are common and very early features of alpha-synucleinopathies, in particular Parkinson's disease. To investigate the hypothesis that these two clinical features in combination are an indicator of evolving alpha-synucleinopathy, olfactory function was assessed in RBD. We studied 30 patients (18 male, 12 female; mean age 48 +/- 14 years, range 19-78 years) with clinical (idiopathic, n = 6; symptomatic, n = 13, mostly associated with narcolepsy) or subclinical (n = 11, associated with narcolepsy) RBD according to standard criteria and 30 age- and gender-matched healthy control subjects using standardized 'Sniffin' Sticks'. RBD patients had a significantly higher olfactory threshold (P = 0.0001), lower discrimination score (P = 0.003), and lower identification score (P = 0.001). Compared with normative data, 97% of the RBD patients had a pathologically increased olfactory threshold, 63% an impaired odour discrimination score, and 63% a decreased identification score. On neurological examination, signs of parkinsonism were newly found in five patients with clinical RBD (not associated with narcolepsy), who usually had a long history of 'idiopathic' RBD. Four of the five patients fulfilled the UK Brain Bank criteria for the clinical diagnosis of Parkinson's disease. The underlying nigrostriatal degeneration of clinical Parkinson's disease was confirmed by I-123-FP-CIT SPECT in one patient and early nigrostriatal degeneration was identified by SPECT in a further two patients with 'idiopathic' clinical RBD out of 11 RBD patients who agreed to undergo SPECT studies. Our study shows that RBD patients have a profound impairment of olfactory function. Five patients with clinical RBD not associated with narcolepsy had clinical or imaging signs of nigrostriatal degeneration. This new clinical finding correlates with the neuropathological staging of Parkinson's disease (stages 1-3) as proposed by Braak. In stage 1, the anterior olfactory nucleus or the olfactory bulb is affected (along with the dorsal motor nucleus of the glossopharyngeal and vagal nerves). In stage 2, additional lesions consistently remain confined to the medulla oblongata and pontine tegmentum, which are critical areas for RBD. Midbrain lesions are found only in stage 3, in particular degeneration of dopaminergic neurons in the substantia nigra pars compacta. Thus, 'idiopathic' RBD patients with olfactory impairment might present with stage 2 preclinical alpha-synucleinopathy. Since narcoleptic patients are not known to have an increased risk of developing parkinsonism, the pathophysiology and clinical relevance of hyposmia in RBD/narcolepsy patients requires further research.

Interactions of sleep and Parkinson's disease.

Sleep disruption represents an important, and clinically relevant facet of Parkinson's Disease [PD]. This review attempts to integrate the current knowledge regarding sleep alterations in PD by examining following: the nature of sleep disturbance in PD, the influence of antiparkinson medication on sleep parameters, the interaction of psychological conditions such as depression and anxiety with sleep, and possible beneficial aspects of sleep in PD. Special emphasis is placed on rapid eye movement sleep behavior disorder and the evidence of it heralding PD and related disorders.

Rapid-eye-movement sleep behaviour disorder and neurodegenerative diseases.

Rapid-eye-movement (REM) sleep behaviour disorder (RBD) is characterised by loss of muscular atonia and prominent motor behaviours during REM sleep. RBD can cause sleep disruption and severe injuries for the patient or bed partner. The disorder is strongly associated with neurodegenerative diseases, such as multiple-system atrophy, Parkinson's disease, dementia with Lewy bodies, and progressive supranuclear palsy. In many cases, the symptoms of RBD precede other symptoms of these neurodegenerative disorders by several years. Furthermore, several recent studies have shown that RBD is associated with abnormalities of electroencephalographic activity, cerebral blood flow, and cognitive, perceptual, and autonomic functions. RBD might be a stage in the development of neurodegenerative disorders and increased awareness of this could lead to substantial advances in knowledge of mechanisms, diagnosis, and treatment of neurodegenerative disorders.
