Poor sleep quality is well recognised in both post-traumatic stress disorder (PTSD) and pain conditions. Comorbid chronic pain is prevalent in populations with PTSD and is believed to maintain symptoms of PTSD and increase the complexity of the condition. Ongoing diminished sleep quality may serve to maintain pain and PTSD symptoms, and thus affect the efficacy of first-line PTSD treatment.

Identifying early predictors of cognitive decline and at-risk individuals is essential for timely intervention and prevention of dementia. This study aimed to detect neurobiological changes and factors related to cognitive performance in the Metropolit 1953 Danish male birth cohort. We analyzed data from 582 participants, aged 57-68 years, using machine learning techniques to group cognitive trajectories into four clusters differentiating high- and low-performing groups.

Objectives: To investigate the influence of wine, beer, and spirits consumption, respectively, on non-pathological, age-related cognitive decline from young adulthood to late midlife in a large follow-up study of Danish men.

Methods: The study includes 2456 middle-aged Danish men from the Lifestyle and Cognition Follow-up study 2015, with information on adult-life consumption (from age 26) of wine, beer, and spirits self-reported in late midlife and age-related cognitive decline assessed using the same validated intelligence test administered in young adulthood and late midlife. Associations were adjusted for consumption of other alcoholic beverages, year of birth, age at follow-up, retest interval, education, young adulthood intelligence, and personality.

Studies have shown a high prevalence of trauma and PTSD among patients with severe mental illness, but relatively few studies have examined the outcomes of PTSD treatment for this patient group. The aim of this case-series was to assess the feasibility of a Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) intervention for PTSD in people with psychosis. The study examined the possibilities and obstacles when treating this population within clinical settings.

Introduction: Cannabis is by far the most widely used and abused drug listed on the Drug Enforcement Administration's Schedule I, which includes drugs with a high potential for abuse. There is evidence of short-term negative effects of cannabis use on cognition, but only a limited number of studies have explored the association between cannabis use and age-related cognitive decline. The aim of the present study was to investigate the relationship between cannabis use and age-related cognitive decline from early adulthood to late midlife.

Education-related variables are positively associated with intelligence in both causal directions, but little is known about the associations' underlying genetically and environmentally intertwined processes and many 'third variables' are probably involved too. In this study, we investigated how school achievement, measured by grade point average (GPA), moderated intelligence test score variation in young adulthood in broadly representative samples from the U.S.

Article Synopsis
  • The study investigates the link between cognitive ability in young adulthood and benzodiazepine use later in life, as well as its impact on cognitive decline in middle age.
  • Analysis of data from over 335,000 men shows that lower cognitive scores at age 19 correlate with a higher likelihood of benzodiazepine use and greater cognitive decline for those who used the medication regularly.
  • Findings suggest that while lower cognitive ability increases benzodiazepine usage, the resulting cognitive decline from high usage is statistically significant but may not be clinically important.

Dropout from mental health treatment is a substantial hindrance to relevant and effective treatment. Despite the high prevalence of PTSD among refugees, research into their treatment dropout has received limited attention. This study aimed to identify patterns and predictors of treatment dropout versus completion through different treatment stages.

Despite an increased focus on the impact of post-migratory factors on the health of trauma-affected refugees, research on the influence of residence permit is limited. This influence may manifest on the outcome of psychiatric treatment. Accordingly, the aim of this study was to examine the role of temporary residence permit on symptom severity and treatment outcome among trauma-affected refugees in PTSD treatment.

Individuals with schizophrenia (SZ) or bipolar disorder (BP) display cognitive impairments, while their first-degree relatives perform at an intermediate level between the patient groups and controls. However, the environmental impact of having an ill relative likely varies with the type of kinship and some studies suggest that offspring may be particularly disadvantaged. The present study aimed to investigate the relationship between parent and child cognition in parents with SZ or BD and their 7-year-old offspring.

Background: With aging populations worldwide, identification of predictors of age-related cognitive decline is becoming increasingly important. The Danish Aging and Cognition Cohort (DanACo) including more than 5000 Danish men was established to investigate predictors of age-related cognitive decline from young adulthood to late mid-life.

Construction And Content: The DanACo cohort was established through two separate data collections with identical designs involving a follow-up examination in late mid-life of men for whom intelligence test scores were available from their mandatory conscription board examination.

Background: Fatigue, low muscle endurance, muscle weakness and low-grade inflammation are strongly related to frailty at higher age. When signs of self-perceived fatigue and low muscle endurance are interrelated with low-grade inflammation at midlife, they might be used as early markers for frailty. This study investigated whether the interrelationships among self-perceived fatigue, muscle endurance and inflammation can be observed at midlife.

Aims: Alzheimer's disease (AD) is characterized by the accumulation of amyloid beta (Aβ) in the brain. The deposition of Aβ is believed to initiate a detrimental cascade, including cerebral hypometabolism, accelerated brain atrophy, and cognitive problems-ultimately resulting in AD. However, the timing and causality of the cascade resulting in AD are not yet fully established.

Non-adherence to psychotropic drugs may reduce treatment effectiveness and may cause exacerbation of illness. Among migrant populations, studies have identified low adherence to psychotropic drugs. This study aimed to identify factors that were associated with the three basic components of adherence: non-initiation, non-implementation (blood sample), and discontinuation in a clinical sample of trauma-affected refugees diagnosed with posttraumatic stress disorder.

Background: The ICD-11 proposes fundamental changes to the PTSD diagnostic criteria, prompting thorough validation. While this is ideally carried out based on diagnostic interviews, most-and in the case of transcultural psychiatry all-studies have relied on self-reported measures. In this study, we used the International Trauma Interview (ITI) to assess the factor structure of ICD-11 PTSD symptoms in a sample of trauma-affected refugees.
