Circadian rhythm in the assessment of postconcussion insomnia: a cross-sectional observational study.

Background: Insomnia is a major predictor of adverse outcomes in mild traumatic brain injury (mTBI), including concussion; although insomnia symptoms may be due to various sleep disorders, those related to circadian rhythm sleep-wake disorders (CRSWDs) require specific assessment and treatment. The objective of the current study was to determine the prevalence of CRSWD in a sample of treatment-seeking people with chronic insomnia symptoms after an mTBI.

Methods: Participants aged 17-65 years who had experienced an mTBI and reported chronic insomnia were recruited from diverse community clinics in Ontario 3-24 months after their injury to participate in this cross-sectional observational study.

Sleepiness in the Elderly.

Excessive daytime sleepiness has pathologic causes and numerous adverse consequences; therefore, it requires medical attention in older adults. Excessive sleepiness in older adults is often multifactorial and may signal an underlying sleep disorder, chronic medical condition, undiagnosed mood disorder, or side effects of medications. It is associated with increased risk for cognitive decline and dementia in the elderly.

Sleep and melatonin secretion abnormalities in children and adolescents with fetal alcohol spectrum disorders.

Objectives: Caregivers describe significant sleep disturbances in the vast majority of children and adolescents, which is diagnosed as fetal alcohol spectrum disorders (FASD), but objective data on sleep disorders in this population are almost completely lacking. Animal models suggest that intrauterine alcohol exposure may disrupt sleep wake patterns, cause sleep fragmentation, and specifically affect the suprachiasmatic nucleus, thus disrupting melatonin secretion. The objective of this pioneering study was to evaluate sleep and melatonin abnormalities in children with FASD using objective, gold-standard measures.

Fatigue in chronic kidney disease: Definition, assessment and treatment.

Chronic fatigue--an overwhelming subjective feeling of mental or physical exhaustion--impacts patients' everyday functioning and quality of life, delays recovery after hemodialysis, and increases mortality. There are a number of factors that may perpetuate clinically significant fatigue among individuals with chronic kidney disease, including sleep disorders, depression, sedentary lifestyle, anemia, and chronic inflammation. Some of these factors (i.

Fatigue in chronic hepatitis C infection: Understanding patients' experience from a cognitive-behavioural perspective.

Objectives: Fatigue is a leading concern of patients with chronic hepatitis C virus (HCV) infection. Despite its clinical significance, fatigue in HCV is poorly understood and therefore invariably under-treated. A cognitive-behavioural approach offers a framework to understand and treat fatigue, but the characteristics of fatigue in chronic HCV infection have not been documented from a cognitive-behavioural perspective.

When insomnia is not just insomnia: the deeper correlates of disturbed sleep with reference to DSM-5.

Recent scientific evidences have brought a paradigm shift in our approach towards the concepts of insomnia and its management. The differentiation between primary and secondary insomnia was proved more hypothetical than actual and based upon the current evidences insomnia subtypes described in earlier system have been lumped into one-insomnia disorder. Research in this field suggests that insomnia occurring during psychiatric or medical disorders has a bidirectional and interactive relationship with and coexisting medical and psychiatric illnesses.

The importance of fatigue cognitions in chronic hepatitis C infection.

Unlabelled: Chronic Hepatitis C virus (HCV) infection is a source of significant public health burden worldwide. Fatigue is a cardinal patient reported consequence of the disease. HCV infection associated fatigue leads to significant impairment in the quality of life and day-to-day functioning.

Psychological distress and depression in patients with chronic kidney disease.

Depressive disorders are 1.5-4 times more prevalent in medically ill patients than in the general population. Mood disorders can be regarded as the final common pathway developing from the interaction among multiple pathophysiological, psychological, and socioeconomic stressors that chronic illness imposes on the individual.

[Mood disorders in patients with chronic kidney disease: significance, etiology and prevalence of depression].

Due to the rapidly increasing number of end-stage renal disease patients and the high costs of their treatment, all the aspects of kidney disease that may significantly affect clinical outcome (quality of life mortality) deserve increasing attention. It has been established and accepted that in addition to clinical/somatic factors, also psycho-social factors, including depression, may have a significant impact on the clinical outcome of chronic diseases. Depression is considered to be one of the most prevalent mental health problems in patients with chronic kidney disease.
