The present paper initially discusses the possible transitions existing between posttraumatic stress disorder (PTSD) and delusional disorder. With respect to the latter, the main focus is on the psychopathological concept of the so-called sensitive delusion of reference. A patient who developed a delusional disorder secondary to PTSD, which had been precipitated by his involvement in a serious auto accident, is then described. The details of this case seem to lend some support to the hypothesis of a clinical continuum provided that the "trauma" found in PTSD, on the one hand, and the "crucial experience" associated with the sensitive delusion of reference, on the other, positively correlate with the presence of prominent sensitive traits of personality.

Background: Approximately 20-25% of patients who survive medical treatment at an intensive care unit (ICU) develop post-traumatic stress symptoms. There is currently a gap in follow-up care for them. As part of the PICTURE study, general practitioners (GPs) carried out a brief interview-based intervention.

AUTS2 syndrome is characterized by intellectual disability and microcephaly, and is often associated with autism spectrum disorder, but the underlying mechanisms, particularly concerning microcephaly, remain incompletely understood. Here, we analyze mice mutated for the transcriptional regulator AUTS2, which recapitulate microcephaly. Their brains exhibit reduced division of intermediate progenitor cells (IPCs), leading to fewer neurons and decreased thickness in the upper-layer cortex.

Vitiligo is a complex autoimmune skin disorder characterized by depigmentation and immune dysregulation. To elucidate the role of ferroptosis-related genes (FRGs) in vitiligo, we conducted a comprehensive analysis of gene expression data from the GSE53146 and GSE65127 datasets obtained from the GEO database. We identified 31 differentially expressed FRGs (DE-FRGs), with 21 genes upregulated and 10 downregulated.

Exposure and Response Prevention (ERP) is an effective treatment for obsessive-compulsive disorder (OCD), yet the specific underlying mechanisms by which ERP improves symptoms remain unclear. Initial theories suggested that habituation to triggering events and stimuli was the key therapeutic factor in ERP, while other theories highlight the role of developing the ability to tolerate distress, rather than reduction of distress. The current study examined improvements in distress tolerance as a mechanism of OCD, anxiety, and depressive symptom reductions during an ERP-based intensive program.

Sexual minority (SM) individuals appear to be at greater risk for obsessive-compulsive disorder (OCD). Despite this, little is known about OCD presentation and treatment outcomes among SM individuals. Although some research has suggested that SM individuals may be more likely to endorse intrusive thoughts related to violence/sex/religion compared to heterosexual individuals, extant literature has neglected to examine potential differences across different SM groups, a notable limitation given the apparent differences in the types of minority stress that each group experiences and the unique health disparities affecting each group.
