AI Article Synopsis
- - Cognitive deficits like memory and learning are often linked to depression, with motivation suggested as a factor in this connection.
- - A study involving 11,878 children aged 9-11 examined whether the link between depression and cognitive dysfunction could be explained by state, trait, or scar hypotheses and found no support for these theories.
- - Unlike older individuals, children in this study did not show significant cognitive deficits associated with depression, suggesting different patterns of depression-cognition relationships across age groups.
Article Abstract
Research has revealed broad cognitive deficits (e.g., memory, learning) in depression, and that motivation may account for this link. We tested the state (i.e., only present during depression), trait (i.e., underlying vulnerability) and scar (i.e., lasting corollary) hypotheses of cognitive dysfunction in depression. We additionally tested subjective motivation as a mediator of the concurrent depression-cognition link. In a longitudinal sample of 11,878 children ages 9-11, we found no evidence of a concurrent state or longitudinal trait or scar relationship between depression and cognition. The pattern of depression-cognition relationships-which precluded a mediator analysis-in our childhood sample is a departure from previous studies. Our findings indicate that cognitive deficits are not strongly associated with depression in childhood, in contrast with the impairment commonly seen in older individuals with depression.

Psychotherapeutic Interventions Used in Psychological Treatment Studies With Syrian Refugees: A Systematic Review.
Trauma Violence Abuse
December 2024
Department of Psychology, Çankaya University, Ankara, Turkey.
The ongoing conflicts in the Middle East have led to a substantial influx of Syrian refugees, exposing them to severe traumatic experiences and contributing to a range of mental health issues. This systematic review examines psychotherapeutic interventions employed in psychological treatment studies with Syrian refugees, focusing on 22 articles identified across Scopus, PubMed, Web of Science, and ScienceDirect. The review highlights the need for psychotherapeutic intervention for Syrian refugees due to the high prevalence of post-traumatic stress, depression, anxiety, grief, and loss which results from an increased risk of various forms of violence and exploitation.

Institute of Cognitive Neuroscience, University College London, London, United Kingdom.
Background: Cognitive impairment, colloquially termed "brain fog", is one of the most prevalent manifestations of post-Covid syndrome and a major contributor to impaired daily function and reduced quality of life. However, despite the high numbers of affected individuals presenting to clinical services with cognitive impairment, little work has been undertaken to date on the suitability of current memory clinic tests for identifying the cognitive deficits in this new acquired cognitive disorder.The aim of this study was therefore to determine the performance of people with post-Covid syndrome presenting with cognitive impairment on the Addenbrooke's Cognitive Examination-III (ACE-III), a cognitive test used widely in memory clinics.

Prostate cancer is a common malignancy with an increasing incidence in ageing populations. However, older patients with prostate cancer are often underrepresented in traditional clinical trials. The electronic Prostate Cancer Australian and Asian Database (ePAD) is a multi-centre, multi-national prospective clinical registry, that records real world data from a broader population.
