ABSTRACT

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is characterized by episodes of upper airway obstruction during sleep, with a risk of cardiovascular and cerebrovascular diseases. There is no tool in Brazil to measure the impact of treatment on patients with OSAS. OBJECTIVE: To translate and culturally adapt the Sleep Apnea Quality of Life Index (SAQLI) into Brazilian Portuguese. METHODS: The translation and cultural adaptation were carried out in five steps: translation, synthesis of the translations, back translation, review committee and pretesting. RESULTS: A version of a culturally compatible SAQLI was constructed after lexical changes, along with changes to the sentence structures, visual format, instructions and cards. The essence of the questionnaire and its social, emotional, and disease impact in treatment measures was maintained, with 80% understanding. CONCLUSIONS: The questionnaire was translated and adapted culturally to Brazilian Portuguese, and presented good comprehension in the study population.

ABSTRACT

ABSTRACT BACKGROUND: Use of inhaled corticosteroids for managing acute asthma exacerbations has been tested since the 1990s. OBJECTIVE: To compare high doses of inhaled ciclesonide with systemic hydrocortisone for managing acute asthma exacerbations in the emergency department. DESIGN AND SETTING: Double-blind, randomized clinical trial in the public healthcare system of the city of São Paulo. METHODS: Fifty-eight patients with moderate or severe asthma with peak flow < 50% of predicted were randomized into two groups. Over the course of four hours, one group received 1440 mcg of inhaled ciclesonide plus hydrocortisone-identical placebo (ciclesonide + placebo), while the other received 500 mg of intravenous hydrocortisone plus ciclesonide-identical placebo (hydrocortisone + placebo). Both groups received short-acting bronchodilators (fenoterol hydrobromide and ipratropium bromide). The research protocol included spirometry, clinical evaluation, vital signs and electrocardiogram monitoring. Data were obtained at 30 (baseline), 60, 90, 120, 180, and 240 minutes. We compared data from baseline to hour 4, between and within groups. RESULTS: Overall, 31 patients received ciclesonide + placebo and 27 received hydrocortisone + placebo. Inhaled ciclesonide was as effective as intravenous hydrocortisone for improving clinical parameters (Borg-scored dyspnea, P = 0.95; sternocleidomastoid muscle use, P = 0.55; wheezing, P = 0.55; respiratory effort, P = 0.95); and spirometric parameters (forced vital capacity, P = 0.50; forced expiratory volume in the first second, P = 0.83; peak expiratory flow, P = 0.51). CONCLUSIONS: Inhaled ciclesonide was not inferior to systemic hydrocortisone for managing acute asthma exacerbations, and it improved both clinical and spirometric parameters.

ABSTRACT

AIM: There are no studies comparing tests performed at home with those carried out in the laboratory, using the same device. The only studies that have been performed have compared the device used at home with the standard polygraph used in the laboratory. The purpose of this study was therefore to verify the accuracy of the home diagnosis of obstructive sleep apnea syndrome (OSAS) via unassisted type 2 portable polysomnography, compared with polysomnography using the same equipment in a sleep laboratory. METHODS: To avoid any possible order effect on the apnea-hypopnea index (AHI), we randomly created two groups of 20-total 40 patients, according to the test sequence. One of the groups had the first test at home and the second test in the laboratory (H-L); the other group had the first test in the laboratory and the second at home (L-H). The second test always took place on the night immediately following the first test. All polysomnographic monitoring was undertaken with the same equipment, an Embletta X100 system (Embla, Natus Inc., Middleton, USA). The Embletta X100 is a portable polygraph that records eleven polygraph signs: (1) electroencephalogram C4/A; (2) electroencephalogram O2/M1; (3) submental EMG; (4) electrooculogram of the right side; (5) nasal cannula (air flow); (6) respiratory effort against a plethysmographic chest strap; (7) respiratory effort against an abdominal plethysmographic belt; (8) heart rate; (9) saturation of oxyhemoglobin; (10) snoring; and (11) body position. RESULTS: There was no difference in sleep efficiency between the group monitored in the laboratory and the group tested at home (p = 0.30). There was no difference in total sleep time (p = 0.11) or sleep latency (p = 0.52), or in the latency in phases N2 and N3 between the monitoring in the laboratory and at home (N2 p = 0.24; N3 p = 0.09). Some differences occurred regarding the PSG that took place at home, with longer duration of wake after sleep onset (WASO) and longer latency for REM sleep, due to failure of the patient to start the monitoring by pressing the "events" button on the device. In the distribution of sleep phases, there was no difference between the group monitored in the laboratory and the group tested at home. CONCLUSION: Results from home sleep monitoring correlate well with the laboratory "gold standard" and may be an option for diagnosing OSAS in selected patients.

ABSTRACT

INTRODUCTION: We describe a case of sleep state misperception in a patient with a neurotoxoplasmosis lesion in the left nucleocapsular region. CASE REPORT: A 40-year-old female patient presented relating sleeplessness over the past 2 years, concurrent with progressive headaches, dizziness and motor and sensory deficits in the right upper and lower limbs. She had a history of AIDS, on irregular antiretroviral therapy and neurotoxoplasmosis. A polysomnography confirmed the hypothesis of sleep state misperception, and magnetic resonance imaging revealed a residual lesion in the left nucleocapsular region. CONCLUSION: Different models consider that the sleep state misperception could be correlated to structural abnormalities of the central nervous system. A recent study showed that the medial prefrontal cortex had a lower activation in patients with unrefreshing sleep due to chronic fatigue syndrome. This case report highlights the possibility of sleep state misperception having - at least partially - an anatomical substrate in the left nucleocapsular region.

ABSTRACT

The treatment of insomnia is still a challenge in clinical practice. This systematic review of randomized and quasi-randomized clinical trials aims to summarize the evidence for the use of biofeedback techniques in the treatment of chronic insomnia. Studies that compared biofeedback with other techniques of cognitive behavioral therapy, placebo, or absence of treatment were selected. The outcomes evaluated included sleep onset latency, total sleep time, sleep fragmentation, sleep efficiency and subjective sleep quality. Comparing to placebo and absence of treatment, some studies suggest possible benefits from the use of biofeedback for chronic insomnia in decreasing sleep onset latency and number of awakenings; however, there was marked divergence among included studies. There was no evidence of improvement in total sleep time, sleep efficiency and subjective sleep quality. Moreover, the maintenance of long-term benefits lacks evidence for any outcome. In the majority of outcomes evaluated, no significant differences in the effectiveness of biofeedback compared with other cognitive behavioral therapy techniques were observed. This systematic review found conflicting evidence for the effectiveness of biofeedback techniques in the treatment of chronic insomnia. Inter- and intra-group clinical heterogeneity among studies could be a reasonable explanation for the divergent results. These findings emphasize the need of performing further randomized clinical trials of higher methodological quality in order to better delineate the effectiveness of biofeedback on chronic insomnia treatment.

ABSTRACT

OBJECTIVE/BACKGROUND: Machado-Joseph disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is the most common type of autosomal dominant spinocerebellar ataxia (SCA). Sleep disorders have been described as frequent non-motor symptoms in MJD, and with marked impairment on quality of life. However, few studies have evaluated the frequency and characteristics of sleep apnea in MJD. PATIENTS/METHODS: This study analyzed the prevalence of sleep apnea in 47 patients with MJD by using polysomnography. Clinical variables such as age, age at onset of symptoms, duration of symptoms (at time of evaluation), body index mass, ataxia scales severity and CAG repeat length were compared with polysomnographic findings. RESULTS: Thirty four percent of MJD patients had OSAS, and 42.5% had excessive daytime somnolence. There were no differences considering ataxia severity, CAG repetition length or other clinical variable. CONCLUSIONS: Patients with MJD have high frequency of obstructive sleep apnea, and this sleep disorder is not correlated with ataxia severity, CAG repetition length or other clinical variable.

ABSTRACT

OBJECTIVE: Few studies have quantified the prevalence of restless legs syndrome (RLS) in patients with post-polio syndrome (PPS). Our objective was to assess the prevalence and severity of RLS in patients with PPS and to examine the demographic characteristics of this population. METHOD: This was a cross-sectional study conducted from April 2010 to May 2012 at the outpatient Neuromuscular Disorders clinic of Universidade Federal de São Paulo, São Paulo, Brazil. We evaluated 119 patients with PPS, consecutively recruited, and investigated for RLS based on the diagnostic criteria established by the International Restless Legs Syndrome Study Group (IRLSSG). Patients were evaluated with the Brazilian version of the IRLSSG severity scale. RESULTS: The prevalence of RLS was 36% (n = 43; 32 women and 11 men). The ages at onset of RLS (median = 41 years) and PPS (median = 41 years) were concurrent, and the correlation between onset of symptoms of RLS and onset of symptoms of PPS was positive and very strong (Spearman r = 0.93, p = 0.01). The median RLS severity was 23 (range, 20-28). Low educational achievement and depression were predictive of RLS development. CONCLUSION: In the largest population of patients with PPS studied to date, our results indicate a high prevalence of RLS, marked disease severity, and concomitant onset of both conditions in many patients with PPS. Further studies are needed to elucidate a possible pathophysiologic mechanism linking these two conditions. We suggest that all post-polio patients with sensory and motor complaints in the legs be investigated for RLS.

ABSTRACT

BACKGROUND: Restless legs syndrome (RLS) is a common disease affecting about 5% to 15% of the population. Symptoms of RLS can be severe in a minority of and can have a major impact on sleep, mostly sleep initiation, and quality of life. Benzodiazepines are drugs that can induce and maintain sleep and, hence, intuitively are thought to be beneficial to people with RLS. Altough benzodiazepines, particularly clonazepam, are used to treat RLS symptoms, a systematic review done by the American Academy of Sleep Medicine stated that benzodiazepines should not be used as a first-line treatment, although could be used as a coadjuvant therapy. OBJECTIVES: To evaluate the efficacy and safety of benzodiazepine compared to placebo or other treatment for idiopathic RLS, including unconfounded trials comparing benzodiazepines versus open control. SEARCH METHODS: In March 2016 we searched CENTRAL, MEDLINE, Embase and LILACS We checked the references of each study and contacted study authors to identify any additional studies. We considered studies published in any language. SELECTION CRITERIA: Randomised clinical trials of benzodiazepine treatment in idiopathic RLS. DATA COLLECTION AND ANALYSIS: We did not perform data collection and analysis, since we did not include any studies, MAIN RESULTS: We did not identify any studies that met the inclusion criteria of the review. Two cross-over studies are awaiting classification because the cross-over trials did not give data at the end of the first cross-over period. AUTHORS' CONCLUSIONS: The effectiveness of benzodiazepines for RLS treatment is currently unknown.

ABSTRACT

OBJECTIVE: To estimate the prevalence of restless legs syndrome/Willis-Ekbom disease (RLS/WED) and its impact on sleep and quality of life in children and adolescents. METHODS: This was a cross-sectional study conducted in the Municipality of Cássia dos Coqueiros, Brazil. Participants included 383 children and adolescents 5-17 years of age. A comparison group was randomly matched by gender and age with the RLS/WED-affected individuals, pairing one by one. RESULTS: Interviews were conducted for 383 individuals by a neurologist experienced in sleep medicine. RLS/WED was diagnosed using the essential clinical criteria for definitive RLS/WED in children recommended by the International Restless Legs Syndrome Study Group. Sleep and quality of life were evaluated using the Sleep Behavior Questionnaire (SBQ) and the Health-related Quality of Life Questionnaire─Pediatric Quality of Life Inventory (PedsQL). Comparisons were established with a group of randomly selected individuals without RLS/WED, matched by age and gender (control group). The prevalence of RLS/WED symptoms that manifested at least twice a week was 1.9%. The average age of children with RLS/WED was higher compared to the general population (11.5 ± 2.3 vs 9.9 ± 2.5, p < 0.005). A family history of RLS/WED was detected in 90.9% of the patients. The scores obtained by SBQ were higher (53.9 ± 9.4 vs 47.6 ± 10.9, p < 0.047), whereas the scores achieved by PedsQL were lower (69.8 ± 14.8 vs 81.9 ± 10.4, p < 0.003) in children with RLS/WED compared to controls. CONCLUSION: The prevalence of RLS/WED symptoms manifested at least twice in the preceding week was 1.9% in children and adolescents. Worsened sleep and quality of life were observed in the study.

ABSTRACT

Pharmacotherapy has been used as an adjunct to CPAP for treatment of residual excessive sleepiness in patients with a diagnosis of obstructive sleep apnea syndrome (OSAS). However, no studies with a high level of evidence have been conducted to support this practice and confirm its effectiveness. We conducted a meta-analysis to summarize and quantify the effects of pharmacological treatment in adults with OSAS who experience residual excessive sleepiness despite adequate CPAP use. We reviewed clinical trials that compared medications to placebo and evaluated the outcomes residual excessive sleepiness, cognition, and quality of life, as well as treatment effectiveness and safety. The MEDLINE, EMBASE, LILACS, Cochrane Central Register of Controlled Trials - CENTRAL, and PsycINFO electronic databases were searched using highly sensitive search strategies. Trials were only included if measures were taken to ensure effective CPAP treatment. Eight randomized clinical trials were included. Pharmacotherapy with modafinil and armodafinil led to improvement of excessive daytime sleepiness, attention/alertness, and clinical condition as measured with the CGI-C. No improvements in quality of life or other cognitive domains (including memory, executive function, and language) could be confirmed. Pharmacotherapy did not cause any severe adverse effects, but was associated with significant dropout rates as compared with placebo. In conclusion, although our results demonstrate the effectiveness of pharmacological treatment as an adjunct to CPAP, further investigation is necessary to improve confidence in its effects. Many findings on the impact of pharmacotherapy on cognition and quality of life were evaluated through analysis of single studies, with heterogeneity in tests and absence of standardization, which reduced certainty as to whether actual improvement occurred in these outcomes.

ABSTRACT

BACKGROUND: Apnoea is a breathing disorder marked by the absence of airflow at the nose or mouth. In children, risk factors include adenotonsillar hypertrophy, obesity, neuromuscular disorders and craniofacial anomalies. The most common treatment for obstructive sleep apnoea syndrome (OSAS) in childhood is adeno-tonsillectomy. This approach is limited by its surgical risks, mostly in children with comorbidities and, in some patients, by recurrence that can be associated with craniofacial problems. Oral appliances and functional orthopaedic appliances have been used for patients who have OSAS and craniofacial anomalies because they hold the lower jaw (mandible) forwards which potentially enlarges the upper airway and increases the upper airspace, improving the respiratory function. OBJECTIVES: To assess the effects of oral appliances or functional orthopaedic appliances for obstructive sleep apnoea in children. SEARCH METHODS: We searched the following electronic databases: Cochrane Oral Health's Trials Register (to 7 April 2016); Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 3) in the Cochrane Library (searched 7 April 2016); MEDLINE Ovid (1946 to 7 April 2016); Embase Ovid (1980 to 7 April 2016); LILACS BIREME (from 1982 to 7 April 2016); BBO BIREME (from 1986 to 7 April 2016) and SciELO Web of Science (from 1997 to 7 April 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials on 7 April 2016. We placed no restrictions on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: All randomised or quasi-randomised controlled trials comparing all types of oral and functional orthopaedic appliances with placebo or no treatment, in children 15 years old or younger. PRIMARY OUTCOME: reduction of apnoea to less than one episode per hour. SECONDARY OUTCOMES: dental and skeletal relationship, sleep parameters improvement, cognitive and phonoaudiological function, behavioural problems, quality of life, side effects (tolerability) and economic evaluation. DATA COLLECTION AND ANALYSIS: Two review authors screened studies and extracted data independently. Authors were contacted for additional information. We calculated risk ratios with 95% confidence intervals for all important dichotomous outcomes. We assessed the quality of the evidence of included studies using GRADEpro software. MAIN RESULTS: The initial search identified 686 trials. Only one trial, reporting the results from a total of 23 children and comparing an oral appliance to no treatment, was suitable for inclusion in the review. The trial assessed apnoea-hypopnoea, daytime symptoms (sleepiness, irritability, tiredness, school problems, morning headache, thirstiness in the morning, oral breathing and nasal stuffiness) and night-time symptoms (habitual snoring, restless sleep and nightmares measured by questionnaire). Results were inconsistent across outcomes measures and time points. The evidence was considered very low quality. AUTHORS' CONCLUSIONS: There is insufficient evidence to support or refute the effectiveness of oral appliances and functional orthopaedic appliances for the treatment of obstructive sleep apnoea in children. Oral appliances or functional orthopaedic appliances may be considered in specified cases as an auxiliary in the treatment of children who have craniofacial anomalies which are risk factors for apnoea.

ABSTRACT

PURPOSE OF REVIEW: This article provides a description on clinical features and pathophysiology of the main sleep disorders observed in Machado-Joseph disease (MJD). RECENT FINDINGS: Pathological studies have clearly demonstrated that degenerative process in MJD is widespread in the nervous system, and not restricted to the cerebellum. Nonmotor manifestations are frequent and may include pain, cramps, dysautonomia, cognitive deficits, psychiatric manifestations, olfactory deficits, fatigue, nutritional issues, and sleep disorders. SUMMARY: Sleep disorders are frequent in MJD, and include restless legs syndrome, rapid eye movement sleep behavior disorder, excessive daytime sleepiness, insomnia, sleep apnea, periodic limb movements during sleep, parasomnia, and others. Pathophysiological mechanisms related to sleep disorders in Machado-Joseph are complex and poorly understood. Considering that sleep complaints are a treatable condition, recognizing sleep disorders in MJD is relevant.

ABSTRACT

BACKGROUND: Restless legs syndrome (RLS) is a distressing and common neurological disorder that may have a huge impact in the quality of life of those with frequent and intense symptoms. Patients complain of unpleasant sensations in the legs, at or before bedtime, and feel an urge to move the legs, which improves with movement, such as walking. Symptoms start with the patient at rest (e.g. sitting or lying down), and follow a circadian pattern, increasing during the evening or at night. Many pharmacological intervention are available for RLS, including drugs used to treat Parkinson's disease (L-Dopa and dopaminergic agonists), epilepsy (anticonvulsants), anxiety (benzodiazepines), and pain (opioids). Dopaminergic drugs are those most frequently used for treatment of RLS, but some patients do not respond effectively and require other medication. Opioids, a class of medications used to treat severe pain, seem to be effective in treating RLS symptoms, and are recommended for patients with severe symptoms, because RLS and pain appear to share the same mechanism in the central nervous system. All available drugs are associated to some degree with side effects, which can impede treatment. Opioids are associated with adverse events such as constipation, tolerance, and dependence. This justifies the conduct of a systematic review to ascertain whether opioids are safe and effective for treatment of RLS. OBJECTIVES: To asses the effects of opioids compared to placebo treatment for restless legs syndrome in adults. SEARCH METHODS: We searched the Cochrane Central Register of Controlled trials, CENTRAL 2016, issue 4 and MEDLINE, EMBASE, and LILACS up to April 2016, using a search strategy adapted by Cochraneto identify randomised clinical trials. We checked the references of each study and established personal communication with other authors to identify any additional studies. We considered publications in all languages. SELECTION CRITERIA: Randomised controlled clinical trials of opioid treatment in adults with idiopathic RLS. DATA COLLECTION AND ANALYSIS: Two review authors independently screened articles, independently extracted data into a standard form, and assessed for risk of bias. If necessary, they discussed discrepancies with a third researcher to resolve any doubts. MAIN RESULTS: We included one randomised clinical trial (N = 304 randomised; 204 completed; 276 analysed) that evaluated opioids (prolonged release oxycodone/naloxone) versus placebo. After 12 weeks, RSL symptoms had improved more in the drug group than in the placebo group (using the IRLSSS: MD -7.0; 95% CI -9.69 to -4.31 and the CGI: MD -1.11; 95% CI -1.49 to -0.73). More patients in the drug group than in the placebo group were drug responders (using the IRLSSS: RR 1.82; 95% CI 1.37 to 2.42 and the CGI: RR1.92; 95% ICI 1.49 to 2.48). The proportion of remitters was greater in the drug group than in the placebo group (using the IRLSSS: RR 2.14; 95% CI 1.45 to 3.16). Quality of life scores also improved more in the drug group than in the placebo group (MD -0.73; 95% CI -1.1 to -0.36). Quality of sleep was improved more in the drug group measured by sleep adequacy (MD -0.74; 95% CI -1.15 to -0.33), and sleep quantity (MD 0.89; 95% CI 0.52 to 1.26).There was no difference between groups for daytime somnolence, trouble staying awake during the day, or naps during the day. More adverse events were reported in the drug group (RR 1.22; 95% CI 1.07 to 1.39). The major adverse events were gastrointestinal problems, fatigue, and headache. AUTHORS' CONCLUSIONS: Opioids seem to be effective for treating RLS symptoms, but there are no definitive data regarding the important problem of safety. This conclusion is based on only one study with a high dropout rate (moderate quality evidence).

ABSTRACT

ABSTRACT Objective To verify if nighttime feeding habits can influence parasomnia in children. Method Seven private and four public Elementary Schools took part in the study. A total of 595 Sleep Disturbance Scale for Children were distributed to the parents of children aged from 7 to 8 years. Data of dietary recall, starting time to school, physical activity, and nutritional status were studied. Results Of the 226 questionnaires completed, 92 (41%) reported parasomnia. Girls had 2.3 times more the chance to parasomnia than boys. Children who consumed stimulant foods had 2.6 times more chance to have parasomnia than those of children who consumed non-stimulant foods. There were no difference between parasomnia and no-parasomnia groups in food type (p = 0.78) or timing of last meal before bedtime (p = 0.50). Conclusion Our findings suggest that intake of stimulant foods is associated with development of parasomnia in children.


RESUMO Objetivo Verificar se hábitos de alimentação noturna influenciam parassonias em crianças. Método Sete escolas privadas e quatro públicas, de Ensino Fundamental, fizeram parte do estudo. Um total de 595 Escalas de Distúrbio do Sono para Crianças foram distribuídas para os pais de crianças entre 7 e 8 anos. Dados de recordatório alimentar, período escolar, atividade física e estado nutricional foram estudados. Resultados Dos 226 questionários preenchidos, 92 (41%) relataram presença de parassonias. Meninas tiveram 2,3 vezes mais chance de parassonias e crianças que consumiram alimentos estimulantes tiveram 2,6 vezes mais chance de parassonias em relação àquelas que consumiram alimentos não estimulantes. Não houve diferença entre os grupos em relação ao tipo de alimento (p = 0,78) ou horário da última refeição antes de ir para a cama (p = 0,50). Conclusão Nossos achados sugerem que a ingestão de alimentos estimulantes está associada com o desenvolvimento de parassonias em crianças.

ABSTRACT

STUDY OBJECTIVES: To report two female patients with paraneoplastic cerebellar degeneration (PCD) related to breast cancer that presented with rapid eye movement-sleep behavior disorder (RBD) and improved sleep symptoms with immunotherapy. METHODS: The two patients were evaluated through clinical scale and polysomnography before and after therapy with intravenous immunoglobulin. RESULTS: RBD was successfully treated with immunotherapy in both patients. Score on the RBD screening questionnaire dropped from 10 to 1 or 0, allied with the normalization of polysomnographic findings. CONCLUSIONS: A marked improvement in RBD after immunotherapy in PCD raises the hypothesis that secondary RBD may be an immune-mediated sleep disorder.

ABSTRACT

Spinocerebellar ataxias (SCA) are autosomal dominant neurodegenerative disorders that affect the cerebellum and its connections, and have a marked clinical and genetic variability. Machado-Joseph disease (MJD) or spinocerebellar ataxia type 3 (SCA3)--MJD/SCA3--is the most common SCA worldwide. MJD/SCA3 is characterized classically by progressive ataxia and variable other motor and non-motor symptoms. Sleep disorders are common, and include rapid eye movement (REM) sleep behaviour disorder (RBD), restless legs syndrome (RLS), insomnia, excessive daytime sleepiness, excessive fragmentary myoclonus and sleep apnea. This study aims to focus upon determining the presence or not of non-REM (NREM)-related parasomnias in MJD/SCA 3, using data from polysomnography (PSG) and clinical evaluation. Forty-seven patients with clinical and genetic diagnosis of MJD/SCA3 and 47 control subjects were evaluated clinically and by polysomnography. MJD/SCA3 patients had a higher frequency of arousals from slow wave sleep (P < 0.001), parasomnia complaints (confusional arousal/sleep terrors, P = 0.001; RBD, P < 0.001; and nightmares, P < 0.001), REM sleep without atonia (P < 0.001), periodic limb movements of sleep index (PLMSi) (P < 0.001), percentage of N3 sleep (P < 0.001) and percentage of N1 sleep (P < 0.001). These data show that NREM-related parasomnias must be included in the spectrum of sleep disorders in MJD/SCA3 patients.
