Cognitive Impairment After COVID-19-A Review on Objective Test Data.

The aim was to conduct a review on the literature on objective cognitive impairment in patients after COVID-19. We performed a literature review and searched Ovid Medline in February 2021 based on a PECO scheme. Twelve articles met all inclusion criteria.

Long-term effect of cognitive-behavioural therapy in patients with Hypochondriacal Disorder.

Background: Cognitive-behavioural therapy (CBT) is an effective treatment for Hypochondriacal Disorder, but the long-term effect has not been examined extensively.

Aims: To investigate the long-term effect of CBT on Hypochondriacal Disorder using several mental health measures. Follow-up time was at least 10 years.

Psychological distress and sickness absence: Within- versus between-individual analysis.

Background: Uncertainty remains whether associations for psychological distress and sickness absence (SA) observed between and within individuals differ, and whether age, gender and work-related factors moderate these associations.

Methods: We analyzed SA records of 41,184 participants of the Finnish Public Sector study with repeated survey data between 2000 and 2016 (119,024 observations). Psychological distress was measured by the General Health Questionnaire (GHQ-12), while data on SA days were from the employers' registers.

Genetic polymorphisms associated with sleep-related phenotypes; relationships with individual nocturnal symptoms of insomnia in the HUNT study.

Background: In recent years, several GWAS (genome wide association studies) of sleep-related traits have identified a number of SNPs (single nucleotides polymorphism) but their relationships with symptoms of insomnia are not known. The aim of this study was to investigate whether SNPs, previously reported in association with sleep-related phenotypes, are associated with individual symptoms of insomnia.

Methods: We selected participants from the HUNT study (Norway) who reported at least one symptom of insomnia consisting of sleep onset, maintenance or early morning awakening difficulties, (cases, N = 2563) compared to participants who presented no symptoms at all (controls, N = 3665).

Differences in anxiety levels among symptoms of insomnia. The HUNT study.

Objectives: This study aim is to compare anxiety levels among individuals experiencing different symptoms of insomnia.

Design: Case-control study.

Setting: The Nord-Trøndelag Health Study (the HUNT3 study, Norway).

Unravelling the Prospective Associations Between Mixed Anxiety-Depression and Insomnia During the Course of Cognitive Behavioral Therapy.

Objective: Previous studies have suggested that there is a reciprocal relationship between anxiety/depression and insomnia. However, little is known about the prospective relationships between these constructs across the course of cognitive behavioral therapy (CBT). The aim of the study was to examine these relationships in clients who received short-term CBT in a primary care setting.

Variations in circadian genes and individual nocturnal symptoms of insomnia. The HUNT study.

Insomnia is a condition characterized by three nocturnal symptoms: problems with sleep onset or maintenance and early morning awakenings (terminal insomnia). Affected individuals may present one or more of these symptoms. Several studies have shown that insomnia is moderately heritable and that proxy phenotypes for the three insomnia symptoms show different heritabilities.

Apathy is associated with faster global cognitive decline and early nursing home admission in dementia with Lewy bodies.

Background: Little is known about the consequences of apathy in dementia with Lewy bodies (DLB), because previous research on apathy in dementia focused mainly on Alzheimer's disease (AD).

Methods: In this longitudinal study, we included patients with AD (n = 128) and patients with DLB (n = 81). At baseline, we analyzed the associations between apathy and cognition in the total sample and in AD and DLB separately.

Association of sleep duration and sleep quality with the physical, social, and emotional functioning among Australian adults.

Objectives: We aimed to evaluate the interaction of two key determinants of sleep health, quantity and quality, with physical, emotional, and social functioning, in the general population.

Design: Nationally-representative Australian cross-sectional study.

Setting: General population.

A longitudinal study of anxiety and cognitive decline in dementia with Lewy bodies and Alzheimer's disease.

Background: Anxiety in dementia is common but not well studied. We studied the associations of anxiety longitudinally in Alzheimer's disease (AD) and dementia with Lewy bodies (DLB).

Methods: In total, 194 patients with a first-time diagnosis of dementia were included (n = 122 patients with AD, n = 72 patients with DLB).

A systematic review of cognitive decline in dementia with Lewy bodies versus Alzheimer's disease.

Introduction: The aim of this review was to investigate whether there is a faster cognitive decline in dementia with Lewy bodies (DLB) than in Alzheimer's disease (AD) over time.

Methods: PsycINFO and Medline were searched from 1946 to February 2013. A quality rating from 1 to 15 (best) was applied to the included studies.

Frequency and correlates of caregiver-reported sleep disturbances in a sample of persons with early dementia.

Objectives: To identify sleep disturbances in participants with subtypes of dementia and explore clinical correlates.

Design: Cross-sectional.

Setting: Outpatient clinics in western Norway and the Mayo Clinic Study of Aging, Olmsted County, Minnesota.
