The current study explored whether individuals diagnosed with schizophrenia and a high level of PTSD symptoms experience more frequent neutral intrusive memories than individuals diagnosed with schizophrenia with low level PTSD symptoms. Results supported a vulnerability to neutral intrusive memories within the comorbid group, which did not seem to be related to psychotic symptom severity. It is possible that a subgroup of psychotic individuals processes information in a manner that make them susceptible to frequent intrusive memories, characteristic of a PTSD presentation. A longitudinal study is required to specify the development of this vulnerability so as to inform future interventions.

Modernizing power systems into smart grids has introduced numerous benefits, including enhanced efficiency, reliability, and integration of renewable energy sources. However, this advancement has also increased vulnerability to cyber threats, particularly False Data Injection Attacks (FDIAs). Traditional Intrusion Detection Systems (IDS) often fall short in identifying sophisticated FDIAs due to their reliance on predefined rules and signatures.

We examined whether the weak memories of the older adults in that study rendered goal-irrelevant memories insufficiently intrusive to motivate retrieval gating. Young and older participants studied words superimposed on rural or urban scenes, or on pixelated backgrounds.

Introduction: Intrusive memories occur frequently after potentially traumatic events and form a core symptom of posttraumatic stress disorder (PTSD) if they persist. The translational approach of visuospatial interventions tries to target those intrusive memories in order to reduce their frequency predominantly using an intervention including as one component the computer game Despite promising results, the application of has critical drawbacks, e.g.

Post-Traumatic Stress Disorder (PTSD) is mainly characterized by dysregulated fear re- sponses, including hyperarousal and intrusive re-experiencing of traumatic memories. This work delves into the intricate interplay between abnormal fear responses, cortisol dysregulation, and the Hypothalamic-Pituitary-Adrenal (HPA) axis, elucidating their role in the manifestation of PTSD. Giv- en the persistent nature of PTSD symptoms and the limitations of conventional therapies, innovative interventions are urgently needed.
