As people age, they tend to spend more time indoors, and the colours in their surroundings may significantly impact their mood and overall well-being. However, there is a lack of empirical evidence to provide informed guidance on colour choices, irrespective of age group. To work towards informed choices, we investigated whether the associations between colours and emotions observed in younger individuals also apply to older adults.

The European Insomnia Guideline: An update on the diagnosis and treatment of insomnia 2023.

J Sleep Res

December 2023

Department of Clinical Psychology and Psychophysiology, Centre for Mental Health (Department), Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.

Progress in the field of insomnia since 2017 necessitated this update of the European Insomnia Guideline. Recommendations for the diagnostic procedure for insomnia and its comorbidities are: clinical interview (encompassing sleep and medical history); the use of sleep questionnaires and diaries (and physical examination and additional measures where indicated) (A). Actigraphy is not recommended for the routine evaluation of insomnia (C), but may be useful for differential-diagnostic purposes (A).

Interoception-the perception of internal bodily signals-has emerged as an area of interest due to its implications in emotion and the prevalence of dysfunctional interoceptive processes across psychopathological conditions. Despite the importance of interoception in cognitive neuroscience and psychiatry, its experimental manipulation remains technically challenging. This is due to the invasive nature of existing methods, the limitation of self-report and unimodal measures of interoception, and the absence of standardized approaches across disparate fields.

Intrinsic forebrain arousal dynamics governs sensory stimulus encoding.

bioRxiv

October 2023

Department of Biomedical Engineering, The Pennsylvania State University, University Park, PA, 16802, USA.

Article Synopsis
  • The brain's internal dynamics significantly influence how sensory information, like visual stimuli, is encoded, showing that activity patterns occur over several seconds.
  • During passive viewing, visual encoding fluctuates with quasi-periodic spiking cycles, peaking during high arousal states but slowing down during low arousal moments marked by hippocampal ripples.
  • When moving actively, these arousal dynamics change, leading to consistently high visual encoding efficiency without hippocampal activity, suggesting a cycle between external perception and internal memory functions.

Epidemiology Branch, National Institute of Environmental Health Sciences, National Institutes of Health, US Department of Health and Human Services, Research Triangle Park, NC, USA; Division of Intramural Research, National Institute on Minority Health and Health Disparities, National Institutes of Health, US Department of Health and Human Services, Bethesda, MD, USA. Electronic address:

Healthy sleep is essential for physical and mental health, and social wellbeing; however, across the globe, and particularly in developing countries, national public health agendas rarely consider sleep health. Sleep should be promoted as an essential pillar of health, equivalent to nutrition and physical activity. To improve sleep health across the globe, a focus on education and awareness, research, and targeted public health policies are needed.

Beyond the Global Brain Differences: Intraindividual Variability Differences in 1q21.1 Distal and 15q11.2 BP1-BP2 Deletion Carriers.

Biol Psychiatry

January 2024

Department of Medical Genetics, Oslo University Hospital, Oslo, Norway; Norwegian Centre for Mental Disorders Research (NORMENT), Division of Mental Health and Addiction, Oslo University Hospital and Institute of Clinical Medicine, University of Oslo, Oslo, Norway; KG Jebsen Centre for Neurodevelopmental Disorders, University of Oslo, Oslo, Norway.

Article Synopsis
  • Carriers of specific genetic variants (1q21.1 distal and 15q11.2 BP1-BP2) show both regional and global brain structure differences compared to noncarriers, but analyzing these differences can be complicated.
  • The study used MRI data from various groups (carriers and noncarriers) to assess how regional brain characteristics diverge from overall brain structure differences.
  • Findings revealed that certain brain regions in carriers exhibited distinct patterns of cortical surface area and thickness that deviated from the global average, suggesting more complex effects of these genetic variants on brain development.

Background: Musculoskeletal (MSK) pain affects over 80% of People with Parkinson's (PD, PwP) and may, in part, be dopaminergic in origin, as dopaminergic medication often leads to its relief.

Methods: PwP who underwent striatal dopamine transporter visualization with a radiopharmaceutical DaTscan™ ( I-Ioflupane Injection) using a single-photon emission computed tomography (SPECT) as a part of their clinical-diagnostic work up were enrolled in the "Non-motor International Longitudinal Study" (NILS; UK National Institute for Health Research Clinical Research Network Number 10084) and included in this cross-sectional analysis. The association between specific DaTscan binding ratios for each striatum, the caudate nucleus and putamen and clinical ratings for MSK pain (assessed using the King's Parkinson's Disease Pain Scale (KPPS)) were analysed.

Over the last decade, EEG resting-state microstate analysis has evolved from a niche existence to a widely used and well-accepted methodology. The rapidly increasing body of empirical findings started to yield overarching patterns of associations of biological and psychological states and traits with specific microstate classes. However, currently, this cross-referencing among apparently similar microstate classes of different studies is typically done by "eyeballing" of printed template maps by the individual authors, lacking a systematic procedure.

Evidence Accumulation Rate Moderates the Relationship between Enriched Environment Exposure and Age-Related Response Speed Declines.

J Neurosci

September 2023

Turner Institute for Brain and Mental Health and School of Psychological Sciences, Monash University, Melbourne, Victoria 3800, Australia

Older adults exposed to enriched environments (EEs) maintain relatively higher levels of cognitive function, even in the face of compromised markers of brain health. Response speed (RS) is often used as a simple proxy to measure the preservation of global cognitive function in older adults. However, it is unknown which specific selection, decision, and/or motor processes provide the most specific indices of neurocognitive health.
