Perfect Enough to Sleep? Perfectionism and Actigraphy-Determined Markers of Insomnia.

Objectives: Perfectionism is an important factor in insomnia development and maintenance. Previous studies exploring the relationship between perfectionism and insomnia have predominantly relied on self-reported sleep measures. Therefore, this study sought to assess whether actigraphy-measured sleep parameters were associated with perfectionism.

Narcolepsy: Comorbidities, complexities and future directions.

Patients with narcolepsy live with a lifelong sleep-wake disorder, impairing their quality of life, productivity, educational and employment outcomes. Clinicians are becoming aware that a significant aspect of the burden of this disease relates to frequent comorbid conditions, including aspects of the patient's emotional, metabolic, sleep and immune health. This review explores the literature describing the comorbidities seen in patients with narcolepsy, to enhance understanding of these often complex presentations.

Prospective cohort study to evaluate the accuracy of sleep measurement by consumer-grade smart devices compared with polysomnography in a sleep disorders population.

Objectives: Consumer-grade smart devices are now commonly used by the public to measure waking activity and sleep. However, the ability of these devices to accurately measure sleep in clinical populations warrants more examination. The aim of the present study was to assess the accuracy of three consumer-grade sleep monitors compared with gold standard polysomnography (PSG).

Management of insomnia in primary care.

Insomnia can have significant health and economic impacts. In contrast, sleep disturbance is common but does not usually affect daytime activity Short-term approaches for acute insomnia are often appropriate. These include dealing with precipitating factors such as stress Chronic insomnia has a high relapse and recurrence rate.

The DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure identifies high levels of coexistent psychiatric symptomatology in patients referred for insomnia treatment.

Purpose: Referrals to sleep psychology services, even for a perceived single problem such as insomnia, can present with complex, coexistent psychiatric symptoms and comorbid disorders. This study aimed to assess the feasibility of implementing the DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure (CCSM) into a sleep psychology clinic to identify coexistent psychiatric symptomatology in insomnia referrals.

Patients And Methods: Patients were 50 consecutive referrals to a private sleep psychology service within a sleep disorders center in Melbourne, Australia.

Australasian Sleep Association position statement regarding the use of psychological/behavioral treatments in the management of insomnia in adults.

Insomnia disorder is a high prevalence condition with a high disease burden, which, left untreated, can increase risk of poorer health outcomes. Due to Insomnia's tendency towards having a chronic course, long-term treatment approaches are required to reduce the impact of Insomnia over time. After reviewing the available literature, The Australasian Sleep Association (ASA) recommends Cognitive Behavior Therapy for Insomnia (CBT-I) as a first line treatment in the management of Insomnia.

User Compliance and Behavioral Adaptation Associated With Supine Avoidance Therapy.

This study investigates behavioral adaptation to vibrotactile position-avoidance therapy during sleep in patients with obstructive sleep apnea (n =135) across 15 to 52 weeks. The overall compliance, based on nights used ≥ 4 hr, was 71%. Overall regular use, that is, ≥ 4 hr/night over 70% of nights, was 88%.

Cognitive Behavioral Therapy for Chronic Insomnia: A Systematic Review and Meta-analysis.

Background: Because psychological approaches are likely to produce sustained benefits without the risk for tolerance or adverse effects associated with pharmacologic approaches, cognitive behavioral therapy for insomnia (CBT-i) is now commonly recommended as first-line treatment for chronic insomnia.

Purpose: To determine the efficacy of CBT-i on diary measures of overnight sleep in adults with chronic insomnia.

Data Sources: Searches of MEDLINE, EMBASE, PsycINFO, CINAHL, the Cochrane Library, and PubMed Clinical Queries from inception to 31 March 2015, supplemented with manual screening.

A randomized controlled trial of cognitive behavioral therapy for insomnia: an effective treatment for comorbid insomnia and depression.

Unlabelled: Insomnia and depression are highly comorbid conditions that show a complex, bidirectional relationship. This study examined whether cognitive-behavioral therapy for insomnia (CBT-I) delivered by a therapist compared with self-help CBT-I (written materials only) reduces insomnia and depression severity in individuals with comorbid insomnia and depression. A total of 41 participants (18-64 years; 25 females) with comorbid depression and insomnia, treated with antidepressants for at least 6 weeks, were randomized to receive 4 sessions of either CBT-I or self-help CBT-I over 8 weeks.

Insomnia: prevalence, consequences and effective treatment.

Insomnia is common and can have serious consequences, such as increased risk of depression and hypertension. Acute and chronic insomnia require different management approaches. >Chronic insomnia is unlikely to spontaneously remit, and over time will be characterised by cycles of relapse and remission or persistent symptoms.

The emergence of devastating impulse control disorders during dopamine agonist therapy of the restless legs syndrome.

Introduction: The Restless Legs Syndrome is a common sensorimotor disorder, typically amenable to treatment with dopamine agonist therapy. Dopamine agonists have been associated with emergent impulse control disorders (ICDs) when used in patients with Parkinson disease, and ICDs have now been reported in individuals with RLS on dopamine agonist therapy. Our aim was to characterize cases of emergent ICDs in Australian patients with focus on the dopamine agonists implicated and the social significance of ICDs.

Excessive daytime somnolence in spinocerebellar ataxia type 1.

Autosomal dominant spinocerebellar ataxias (SCAs) are progressive neurodegenerative disorders which result in dysfunction of the neuronal systems of the spinal cord, brainstem, and cerebellum. The manifestations of daytime somnolence and abnormal sleep behavior have been described in SCA type 3 (SCA3) and SCA type 6 (SCA6), but as yet have not been described in SCA type 1 (SCA1). We report two cases of sleep disturbance, fatigue and excessive daytime somnolence in individuals with SCA1 and their progress through several therapies.

Prevalence of sleep disordered breathing in paroxysmal and persistent atrial fibrillation patients with normal left ventricular function.

Aims: Recent studies have suggested an emerging link between sleep apnoea and atrial fibrillation (AF). These studies included patients with reduced left ventricular (LV) function which may cause both AF and sleep disordered breathing (SDB). We examined the prevalence of SDB in a population of patients with AF and normal LV function.

Evidence of impaired hypoxic vasodilation after intermediate-duration hypoxic exposure in humans.

Systemic hemodynamics, including forearm blood flow and ventilatory parameters, were evaluated in 21 subjects before and after exposure to 8 h of poikilocapnic hypoxia. To evaluate the role of sympathetic nervous system activation in the changes, in 10 of these subjects, we measured muscle sympathetic nerve activity (MSNA) before and after exposure, and the remaining 11 subjects received intra-arterial phentolamine infusion in the brachial artery to define vascular tone in the absence of sympathetically mediated vasoconstriction. Short-term ventilatory acclimatization occurred as evidenced by a decrease in resting Pco(2) (from 42 +/- 1.

Central sleep apnea in stable methadone maintenance treatment patients.

Study Objectives: Methadone, a long-acting mu-opioid agonist, is an effective treatment for heroin addiction. Our previous data show that 6 of 10 methadone maintenance treatment (MMT) patients had central sleep apnea (CSA). This study aims to confirm these results and to investigate the pathogenesis of the CSA.

Ventilatory responses to hypoxia and hypercapnia in stable methadone maintenance treatment patients.

Rationale: Methadone is a long-acting mu-opioid and is an effective treatment for heroin addiction. Opioids depress respiration, and patients receiving methadone maintenance treatment (MMT) have higher mortality than the general population. Few studies have investigated ventilatory responses to both hypercapnia and hypoxia in these patients.

Cardiorespiratory function in stable methadone maintenance treatment (MMT) patients.

Patients in methadone maintenance programmes (MMT) often smoke tobacco and cannabis and many have ongoing illicit drug use. There is therefore potential for these patients to have abnormal cardiorespiratory function; however, few studies address this in stable MMT patients. We assessed resting cardiorespiratory function on 50 stable MMT patients (25 males, 25 females).
