In a cross-sectional study, Jorm and colleagues (1993. Personality and Individual Differences, 15, 721-723) found that neuroticism was related to poorer cognitive performance in the elderly. The present study was initiated to expand their findings using both cross-sectional and longitudinal data from the Maastricht Aging Study. In contrast to the findings of Jorm and coworkers, neuroticism was not associated with either current cognitive performance or cognitive decline over a period of 3 years.

Natural disasters such as earthquakes leave deep psychological effects on individuals that can lead to posttraumatic stress disorder, and understanding these effects is vital to support psychological recovery processes after trauma. In this context, the aim of this study was to examine the mediating role of emotion regulation difficulties, religious coping, positive reappraisal and seeking social support in the relationship between posttraumatic cognitive attributions and posttraumatic stress disorder in 2023 Kahramanmaraş Pazarcık, Elbistan and Hatay Yayladağı earthquake survivors (N = 408). The findings from the multiple mediation analysis showed the indirect effect of posttraumatic cognitive attribution on PTSD through difficulties in emotion regulation, religious coping, positive reappraisal, and seeking social support.

Background: Axial postural abnormalities (APAs) are frequent and disabling axial symptoms of Parkinson's disease (PD). Image-based measurement is considered the gold standard but may not accurately detect the true severity of APAs because these symptoms can appear or get worse under dynamic conditions.
Objective: The aim was to evaluate quantitative changes in APAs degree during prolonged standing and walking in both single- and dual-task conditions (motor + cognitive).
Prehabilitation of Patients With Oesophageal Malignancy Undergoing Peri-Operative Treatment (Pre-EMPT): Outcomes From a Prospective Controlled Trial.

Department of Upper GI and General Surgery, Guy's and St Thomas' NHS Foundation Trust, London, United Kingdom.
Background: The Pre-EMPT study aimed to determine if structured exercise could reduce length of stay, post-operative complications and improve fitness and health-related quality of life (HQRL) in patients undergoing neoadjuvant chemotherapy (NAC) and oesophagectomy.
Methods: A prospective non-randomised trial compared a standard care pathway (control) to a structured prehabilitation exercise programme (intervention) commenced before NAC and surgery for oesophageal adenocarcinoma. Length of hospital stay and post-operative complications were recorded.

Introduction: Changes in sleep physiology can predate cognitive symptoms by decades in persons with Alzheimer's disease (AD), but it remains unclear which sleep characteristics predict cognitive and neurodegenerative changes after AD onset.
Methods: Using data from a prospective cohort of mild to moderate AD (n = 60), we analyzed non-rapid eye movement sleep spindles and slow oscillations (SOs) at baseline and their associations with baseline amyloid beta (Aβ) and tau and with cognition from baseline to 3-year follow-up.
Results: Higher spindle and SO activity predicted significant changes in Aβ and tau at baseline, lower Alzheimer's Disease Assessment Scale Cognitive Subscale (better cognitive performance) score, and higher Mini-Mental State Examination score from baseline to 36 months.
Frontopolar Cortex Interacts With Dorsolateral Prefrontal Cortex to Causally Guide Metacognition.

Department of Psychology, Ludwig Maximilian University Munich, Munich, Germany.
Accurate metacognitive judgments about an individual's performance in a mental task require the brain to have access to representations of the quality and difficulty of first-order cognitive processes. However, little is known about how accurate metacognitive judgments are implemented in the brain. Here, we combine brain stimulation with functional neuroimaging to determine the neural and psychological mechanisms underlying the frontopolar cortex's (FPC) role in metacognition.
