Development and evaluation of a personalised sleep care plan on child and adolescent in-patient mental health wards.

AIMS AND METHOD: The study evaluated a package of measures to improve sleep on psychiatric wards admitting patients from children and young people's services (CYPS). Sleep disturbance has significant impact on adolescent mental health, and in-patient wards can directly cause sleep disturbance, independent of the problem that led to admission. We developed a CYPS-specific package (TeenSleepWell) that promoted a better sleep environment, enhanced staff education about sleep, screened for sleep disorders, and raised awareness of benefits and side-effects of hypnotics. This included personalised sleep care plans that allowed a protected 8 h sleep period when safe. RESULTS: Evaluation over 2 years showed enhanced in-patient care: 57% of patients were able to have a protected sleep period. There was no increase in adverse events and there was a decrease in hypnotics issued. CLINICAL IMPLICATIONS: Improving sleep during in-patient CYPS admissions is possible and personalised sleep care plan should be a care standard.

Hypothalamic involvement in multiple system atrophy: A structural MRI study.

OBJECTIVE: To investigate hypothalamic atrophy and its clinical correlates in multiple system atrophy (MSA) in-vivo. BACKGROUND: MSA is characterized by autonomic dysfunction and parkinsonian/cerebellar manifestations. The hypothalamus regulates autonomic and homeostatic functions and is also involved in memory and learning processes. METHODS: 11 MSA, 18 Parkinson's Disease (PD) and 18 Healthy Controls (HC) were included in this study. A validated and automated hypothalamic segmentation tool was applied to 3D-T1-weighted images acquired on a 3T MRI scanner. MSA hypothalamic volumes were compared to those of PD and HC. Furthermore, the association between hypothalamic volumes and scores of autonomic, depressive, sleep and cognitive manifestations were investigated. RESULTS: Posterior hypothalamus volume was reduced in MSA compared to controls (t = 2.105, p = 0.041) and PD (t = 2.055, p = 0.046). Total hypothalamus showed a trend towards a reduction in MSA vs controls (t = 1.676, p = 0.101). Reduced posterior hypothalamus volume correlated with worse MoCA scores in the parkinsonian (MSA + PD) group and in each group separately, but not with autonomic, sleep, or depression scores. CONCLUSIONS: In-vivo structural hypothalamic involvement may be present in MSA. Reduced posterior hypothalamus volume, which includes the mammillary bodies and lateral hypothalamus, is associated with worse cognitive functioning. Larger studies on hypothalamic involvement in MSA and its clinical correlates are needed.

Sleep disorders in Lewy body dementia: Mechanisms, clinical relevance, and unanswered questions.

In Lewy body dementia (LBD), disturbances of sleep and/or arousal including insomnia, excessive daytime sleepiness, rapid eye movement (REM) sleep behavior disorder, obstructive sleep apnea, and restless leg syndrome are common. These disorders can each exert a significant negative impact on both patient and caregiver quality of life; however, their etiology is poorly understood. Little guidance is available for assessing and managing sleep disorders in LBD, and they remain under-diagnosed and under-treated. This review aims to (1) describe the specific sleep disorders which occur in LBD, considering their putative or potential mechanisms; (2) describe the history and diagnostic process for these disorders in LBD; and (3) summarize current evidence for their management in LBD and consider some of the ongoing and unanswered questions in this field and future research directions.

Corrigendum: The longitudinal progression of autonomic dysfunction in Parkinson's disease: a 7-year study.

The longitudinal progression of autonomic dysfunction in Parkinson's disease: A 7-year study.

Background: Autonomic dysfunction, including gastrointestinal, cardiovascular, and urinary dysfunction, is often present in early Parkinson's Disease (PD). However, the knowledge of the longitudinal progression of these symptoms, and the connection between different autonomic domains, is limited. Furthermore, the relationship between the presence of autonomic symptoms in early-stage PD and olfactory dysfunction, a possible marker of central nervous system involvement, has not been fully investigated. Objectives: We aimed to investigate the occurrence and progression of autonomic dysfunction in recently diagnosed (< 2 years) untreated PD patients and determine any coexistence of symptoms in individual patients. We also investigated the relationship between autonomic symptoms, olfactory dysfunction, and motor impairment. Methods: Data were obtained from the Parkinson's Progression Markers Initiative (PPMI) database. Autonomic dysfunction was measured using the Scales for Outcomes in Parkinson's Disease (SCOPA-AUT). Symptom frequency and mean scores over 7 years were determined. The simultaneous occurrence of different autonomic symptoms was also examined. Finally, the relationships between SCOPA-AUT scores, olfactory dysfunction, and motor impairment were investigated using the University of Pennsylvania Smell Identification Test (UPSIT) and the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), respectively. Results: Follow-up data were available for 7 years for 171 PD patients and for 5 years for 136 HCs. Mean SCOPA-AUT score increased significantly from baseline to the 7-year follow-up for each autonomic domain, except for female sexual dysfunction. Most patients reported three or more autonomic symptoms. Common clusters of symptoms were composed of combinations of gastrointestinal, urinary, thermoregulatory, and sexual dysfunction. At baseline, greater SCOPA-AUT total score was associated with lower UPSIT scores (r = -0.209, p = 0.006) and with greater total MDS-UDPRS III score (r = 0.218, p = 0.004). Conclusions: Autonomic dysfunction, often with coexistence of autonomic manifestations, is common in early PD and progressively worsens over the first 7 years of disease, suggesting that these symptoms should be addressed with appropriate treatments early in the disease. The association between greater autonomic dysfunction and greater olfactory impairment, coupled with the association with more severe motor scores at baseline, indicates that patients who show more severe autonomic dysfunction could also have more severe involvement of the central nervous system at the time of diagnosis.

Online education for safer opioid prescribing in hospitals-lessons learnt from the Opioid Use Change (OUCh) project.

BACKGROUND: Opioids are often required for acute inpatient pain relief but lack of knowledge about common and less common long-term side effects can lead to inappropriate discharge prescribing. There are few validated educational tools available for junior prescribers on hospital wards. Education around opioid prescribing and deprescribing remains limited in the undergraduate curriculum and yet almost all controlled drug prescribing in hospitals is done by junior doctors. METHODS: A 5-minute video was developed with iterative feedback from medical students, junior prescribers, pain specialists, primary care educational leads, and a patient who had developed opioid addiction after hospital prescribing. It explained the need for clear stop dates on discharge summaries and the range of opioid side effects. It also highlighted the hospital admission as an opportunity to reduce inappropriate high-dose opioids. A short knowledge-based quiz before and after viewing the video was used to evaluate the impact on and change in knowledge and confidence around opioid prescribing. This tool was designed to be used entirely online to allow delivery within existing mandatory training. RESULTS: Feedback was positive and showed that knowledge of side effects significantly increased but also contacts with ward pharmacists and the acute pain team increased. Junior doctors highlighted that the undergraduate curriculum did little to prepare them for prescription addiction and that pharmacy and senior support was needed to support any changes in longer-term, high-dose opioids. CONCLUSIONS: This short educational video improved knowledge of safe opioid prescribing and could be incorporated within wider opioid education in UK healthcare.

Longitudinal Studies of Sleep Disturbances in Parkinson's Disease.

PURPOSE OF REVIEW: Sleep disorders are among the most common non-motor symptoms in Parkinson's disease (PD). Recent longitudinal studies of sleep in PD have utilized validated sleep questionnaires and video-polysomnography performed over multiple time points. This review summarizes existing longitudinal studies focusing on the prevalence, associations, and changes of sleep disorders in PD over time, as well as the methodologies used in these studies. RECENT FINDINGS: Fifty-three longitudinal studies of sleep in PD were identified: excessive daytime sleepiness, insomnia, obstructive sleep apnea, rapid eye movement sleep behavior disorder (RBD), restless legs syndrome, and shift work disorder were studied in addition to other studies that had focused on either multiple sleep disorders or broadly on sleep disorders as a whole. The prevalence of sleep disorders increases over time and are associated particularly with non-motor features of disease. RBD is now considered an established prodromal feature of PD, but other sleep disorders do not clearly increase risk of subsequent PD. Further work is necessary to determine if treatment of sleep disorders in PD alters disease symptom and their progression or reduces PD risk. Longitudinal studies of sleep in PD have demonstrated a high prevalence of sleep disorders that are associated with non-motor features of PD which can increase over time. More work is necessary to determine if treatment of sleep disorders can alter the course of PD.

Delivering an advice and guidance service in neurology.

It is increasingly common for secondary care to provide advice to primary care without an outpatient appointment. Even before the increased telemedicine during COVID-19, many hospital services gave advice alone for some referrals, yet there are few published data about patient outcomes. Does advice and guidance alter outpatient numbers or simply mean that patients are seen later? Which neurological conditions can we manage at a distance? Do complaints increase from either primary care or patients? Do clinics become more complex and time consuming? Our department has developed an advice and guidance service embedded within the English electronic referral system since 2017, allowing detailed analysis of the outcome of 6500 patients over 2.5 years. We suggest ways to set up and run a neurology advice and guidance service, looking at the potential benefits and the barriers.

The relationship between sleep and depression and bipolar disorder in children and young people.

BACKGROUND: Sleep difficulties are often reported in practice, and are part of the diagnostic criteria for depression and bipolar disorder. AIMS: To inform the understanding of the relationship between sleep and both depression and bipolar disorder. METHOD: We conducted a narrative literature review of affective disorders and sleep difficulties in children and young people. RESULTS: Specific sleep disorders, such as parasomnias, narcolepsy and sleep-related movement disorders, are associated with depression, whereas insomnia, obstructive sleep apnoea and circadian rhythm disorders are associated with both depression and bipolar disorder in children and young people. Conversely, children and young people with depression can present with a number of sleep difficulties, and these are associated with higher depression severity and greater fatigue, suicidal ideation, physical complaints, pain and decreased concentration. Sleep disturbances among adolescents with bipolar disorder can affect the severity of depressive and manic symptoms, are a poor prognostic indicator and have been associated with social and academic impairment. Antidepressants and antipsychotics can directly affect sleep architecture, which clinicians need to be aware of. Non-pharmacological interventions for sleep problems could prevent and/or minimise the risk of relapse in affective disorders. CONCLUSIONS: Sleep difficulties can occur before, during and after an episode of depression or bipolar disorder, and have a higher prevalence in affective disorders compared with the general population. A multi-modal approach would include the treatment of both the affective and specific sleep disorder. Further research is needed in this field to understand the impact of combined interventions on clinical outcomes.

The relationship between physical activity, BMI, circadian rhythm, and sleep with cognition in bipolar disorder.

BACKGROUND: Cognitive deficits affect a significant proportion of patients with bipolar disorder (BD). Problems with sustained attention have been found independent of mood state and the causes are unclear. We aimed to investigate whether physical parameters such as activity levels, sleep, and body mass index (BMI) may be contributing factors. METHODS: Forty-six patients with BD and 42 controls completed a battery of neuropsychological tests and wore a triaxial accelerometer for 21 days which collected information on physical activity, sleep, and circadian rhythm. Ex-Gaussian analyses were used to characterise reaction time distributions. We used hierarchical regression analyses to examine whether physical activity, BMI, circadian rhythm, and sleep predicted variance in the performance of cognitive tasks. RESULTS: Neither physical activity, BMI, nor circadian rhythm predicted significant variance on any of the cognitive tasks. However, the presence of a sleep abnormality significantly predicted a higher intra-individual variability of the reaction time distributions on the Attention Network Task. CONCLUSIONS: This study suggests that there is an association between sleep abnormalities and cognition in BD, with little or no relationship with physical activity, BMI, and circadian rhythm.

Exploration of Sleep as a Specific Risk Factor for Poor Metabolic and Mental Health: A UK Biobank Study of 84,404 Participants.

PURPOSE: Short and long sleep durations have adverse effects on physical and mental health. However, most studies are based on self-reported sleep duration and health status. Therefore, this longitudinal study aims to investigate objectively measured sleep duration and subsequent primary health care records in older adults to investigate the impact of sleep duration and fragmentation on physical and mental health. METHODS: Data on objective sleep duration were measured using accelerometry. Primary care health records were then obtained from the UK Biobank (n=84,404). Participants (mean age, 62.4 years) were divided into five groups according to their sleep duration derived from the accelerometry data: <5 hours, 5-6 hours, 6-7 hours, 7-8 hours and >8 hours. ICD-10 codes were used for the analysis of primary care data. Wake after sleep onset, activity level during the least active 5 hours and episodes of movement during sleep were analysed as an indication for sleep fragmentation. Binary regression models were adjusted for age, gender and Townsend deprivation score. RESULTS: A "U-shaped" relationship was found between sleep duration and diseases including diabetes, hypertension and heart disease and depression. Short and long sleep durations and fragmented sleep were associated with increased odds of disease. CONCLUSION: Six to eight hours of sleep, as well as less fragmented sleep, predicted better long-term metabolic and mental health.

The Smarter Sleep educational interventions: an initiative to reduce hypnotic prescribing in in-patient psychiatric care.

AIMS AND METHOD: In-patients on mental health wards are commonly prescribed hypnotics for the long-term management of disturbed sleep. Specific sleep disorders remain underdiagnosed and effective behavioural interventions are underused. We developed a suite of three educational interventions (a video, poster and handbook) about sleep, sleep disorders, the safe prescribing of hypnotics and use of psychological strategies (sleep hygiene and cognitive-behavioural therapy for insomnia, CBTi) using co-design and multiprofessional stakeholder involvement. This controlled before-and-after study evaluated the effectiveness of these interventions across seven in-patient psychiatric wards, examining their impact on hypnotic prescribing rates and staff confidence scores (data collected by retrospective drug chart analysis and survey respectively). RESULTS: A marked reduction was seen in the percentage of patients prescribed hypnotics on in-patient prescription charts (-24%), with a 41% reduction in the number of hypnotics administered per patient (mean reduction -1.142 administrations/patient). CLINICAL IMPLICATIONS: These simple educational strategies about the causes and treatment of insomnia can reduce hypnotic prescribing rates and increase staff confidence in both the medical and psychological management of insomnia.

Sleep disturbance in movement disorders: insights, treatments and challenges.

Sleep and circadian rhythm disturbances are central features of many movement disorders, exacerbating motor and non-motor symptoms and impairing quality of life. Understanding these disturbances to sleep is clinically important and may further our understanding of the underlying movement disorder. This review evaluates the current anatomical and neurochemical understanding of normal sleep and the recognised primary sleep disorders. In addition, we undertook a systematic review of the evidence for disruption to sleep across multiple movement disorders. Rapid eye movement sleep behaviour disorder has emerged as the most reliable prodromal biomarker for the alpha synucleinopathies, including Parkinson's disease and multiple system atrophy, often preceding motor symptom onset by several years. Abnormal sleep has also been described for many other movement disorders, but further evidence is needed to determine whether this is a primary or secondary phenotypic component of the underlying condition. Medication used in the treatment of motor symptoms also affects sleep and can aggravate or cause certain sleep disorders. Within the context of movement disorders, there is also some suggestion of a shared underlying mechanism for motor and sleep pathophysiology, with evidence implicating thalamic and brainstem structures and monoaminergic neurotransmission. This review highlights the need for an understanding of normal and abnormal sleep within the movement disorder clinic, an ability to screen for specific causes of poor sleep and to treat sleep disturbance to improve quality of life. Key sleep disorders also act as important biomarkers and have implications in diagnosis, prognosis and the development of future therapies.

Sleep and Circadian Rhythm Disorder in Bipolar Affective Disorder.

Symptoms of affective disorders encompass a range of changes to biological processes such as sleep and appetite. These processes are regulated over a 24-h cycle known as the circadian rhythm. Sleep is a particularly useful marker of this rhythm as it is readily measurable and functionally significant. Sleep disturbance is common in bipolar affective disorder and may act as a marker, and precipitant, of relapse. Circadian rhythms are modulated by environmental and social cues and have been shown to be influenced by treatment in BPAD. As such understanding of circadian rhythms may lead to a better understanding of the pathophysiology of BPAD and its treatment. This chapter will explore the neurobiology of the circadian clock and the putative role of circadian rhythm dysregulation in the pathophysiology and treatment of bipolar affective disorder (BPAD).

Progression of sleep disturbances in Parkinson's disease: a 5-year longitudinal study.

BACKGROUND: Sleep disorders can occur in early Parkinson's disease (PD). However, the relationship between different sleep disturbances and their longitudinal evolution has not been fully explored. OBJECTIVE: To describe the frequency, coexistence, and longitudinal change in excessive daytime sleepiness (EDS), insomnia, and probable REM sleep behavior disorder (pRBD) in early PD. METHODS: Data were obtained from the Parkinson's Progression Markers Initiative (PPMI). EDS, insomnia, and pRBD were defined using the Epworth Sleepiness Scale, MDS-UPDRS Part I sub-item 1.7, and RBD screening questionnaire. RESULTS: 218 PD subjects and 102 controls completed 5 years of follow-up. At baseline, 69 (31.7%) PD subjects reported one type of sleep disturbance, 25 (11.5%) reported two types of sleep disturbances, and three (1.4%) reported all three types of sleep disturbances. At 5 years, the number of PD subjects reporting one, two, and three types of sleep disturbances was 85 (39.0%), 51 (23.4%), and 16 (7.3%), respectively. Only 41(18.8%) patients were taking sleep medications. The largest increase in frequency was seen in insomnia (44.5%), followed by EDS (32.1%) and pRBD (31.2%). Insomnia was the most common sleep problem at any time over the 5-year follow-up. The frequency of sleep disturbances in HCs remained stable. CONCLUSIONS: There is a progressive increase in the frequency of sleep disturbances in PD, with the number of subjects reporting multiple sleep disturbances increasing over time. Relatively a few patients reported multiple sleep disturbances, suggesting that they can have different pathogenesis. A large number of patients were not treated for their sleep disturbances.

Feasibility and utility of enhanced sleep management on in-patient psychiatry wards.

AIMS AND METHOD: Sleep disturbance is common in psychiatry wards despite poor sleep worsening mental health. Contributory factors include the ward environment, frequent nightly checks on patients and sleep disorders including sleep apnoea. We evaluated the safety and feasibility of a package of measures to improve sleep across a mental health trust, including removing hourly checks when safe, sleep disorder screening and improving the ward environment. RESULTS: During the pilot there were no serious adverse events; 50% of in-patients were able to have protected overnight sleep. Hypnotic issuing decreased, and feedback from patients and staff was positive. It was possible to offer cognitive-behavioural therapy for insomnia to selected patients. CLINICAL IMPLICATIONS: Many psychiatry wards perform standardised, overnight checks, which are one cause of sleep disruption. A protected sleep period was safe and well-tolerated alongside education about sleep disturbance and mental health. Future research should evaluate personalised care rather than blanket observation policies.

Restless legs syndrome and periodic limb movements of sleep.

Restless legs syndrome describes a curious need to stretch and move in response to an unpleasant feeling in the legs. For most people who have this, as they are drifting off to sleep there is a twitch of the toe, foot and ankle followed by another and then another. The limb movements are strikingly periodic and are described as such by frustrated bed partners. The pathophysiology remains debated but is likely to involve dopaminergic dysfunction and ascending arousal systems. Despite a prevalence of 5-10% in the general population, the variable nature of symptoms and difficulty describing the dysaesthesia often leads to delay in treatment. This article outlines the diagnostic criteria, medication and comorbidities that modify symptoms, the impact of restless legs syndrome on health, and symptomatic management. Several licensed therapies are effective but the dopamine agonists in particular can cause challenging side effects and paradoxically worsen symptoms over time. Case histories are reviewed to guide physicians.

Objective sleep assessment in >80,000 UK mid-life adults: Associations with sociodemographic characteristics, physical activity and caffeine.

STUDY OBJECTIVES: Normal timing and duration of sleep is vital for all physical and mental health. However, many sleep-related studies depend on self-reported sleep measurements, which have limitations. This study aims to investigate the association of physical activity and sociodemographic characteristics including age, gender, coffee intake and social status with objective sleep measurements. METHODS: A cross-sectional analysis was carried out on 82995 participants within the UK Biobank cohort. Sociodemographic and lifestyle information were collected through touch-screen questionnaires in 2007-2010. Sleep and physical activity parameters were later measured objectively using wrist-worn accelerometers in 2013-2015 (participants were aged 43-79 years and wore watches for 7 days). Participants were divided into 5 groups based on their objective sleep duration per night (<5 hours, 5-6 hours, 6-7 hours, 7-8 hours and >8 hours). Binary logistic models were adjusted for age, gender and Townsend Deprivation Index. RESULTS: Participants who slept 6-7 hours/night were the most frequent (33.5%). Females had longer objective sleep duration than males. Short objective sleep duration (<6 hours) correlated with older age, social deprivation and high coffee intake. Finally, those who slept 6-7 hours/night were most physically active. CONCLUSIONS: Objectively determined short sleep duration was associated with male gender, older age, low social status and high coffee intake. An inverse 'U-shaped' relationship between sleep duration and physical activity was also established. Optimal sleep duration for health in those over 60 may therefore be shorter than younger groups.

Parasomnia overlap disorder with adolescent-onset presumed REM sleep behavior disorder converting to Parkinson's disease after 48 years.

BACKGROUND: It is now recognized that the vast majority of individuals with typical RBD will develop a synucleinopathy; usually 11-16 years after symptom onset. Parasomnia Overlap Disorder (POD) with adolescent-onset dream enactment behavior with phenoconversion to neurodegenerative disease after a long latency has not been previously described. PATIENT: We present a case of a 65-year-old man with presumptive POD who had co-morbid childhood onset sleep walking and adolescent-onset dream enactment behavior beginning at age 17, with subsequent evolution to an increasingly troublesome REM sleep behavior disorder (RBD) at age 64 with Parkinson's Disease (PD) developing a year later. RESULTS: Polysomnography performed at age 64 was consistent with a diagnosis of RBD. Dream enactment behavior preceded PD diagnosis by at least 48 years. Our case represents the youngest reported RBD case who developed PD. CONCLUSIONS: We report the first case of adolescent onset, presumed RBD in the context of presumptive POD developing neurodegenerative disease. Adolescent-onset RBD may have similar prognostic implications as typical RBD, where future phenoconversion to a synucleinopathy is expected.

An evaluation of sleep disturbance on in-patient psychiatric units in the UK.

Aims and methodSleep disturbance is common on in-patient psychiatry wards. This study explored subjective and objective patterns of sleep disturbance and contributory environmental factors. Participants were recruited from mental health acute admission wards and had a range of subjective and objective assessments of sleep. Light intensity and noise levels were measured to characterise potential environmental causes for poor sleep. RESULTS: We recruited 20 patients; 15% were high risk for obstructive sleep apnoea. Nineteen participants reported poor sleep quality on the Pittsburgh Sleep Quality Index, and 90% had significant sleep fragmentation with objective measures. Inside light levels were low (day <200 lux and night <10 lux). Night sound levels were 40-90 db.Clinical implicationsSleep disturbance was highly prevalent. Increased awareness of sleep disorders is needed. Modifiable environmental factors on the ward were implicated, therefore increased awareness and a change of approach to sleep disturbance in in-patient psychiatry is recommended.Declaration of interestNone.
