Objectives: Stroke-induced cognitive and mood disorders are closely related to glucocorticoids released during hypothalamic-pituitary-adrenal (HPA) axis activation. There are many studies on the relationship between cortisol levels and post-stroke cognitive impairment (PSCI) and post-stroke depression (PSD). This paper provides a scoping review of these studies to clarify the effect of cortisol on PSCI and PSD, thereby providing a theoretical basis for clinical diagnosis and treatment.
Materials And Methods: We searched for literature published up to October 2023 on the association of cortisol with post-stroke cognitive and emotional disorders in the PubMed, Web of Science, Cochrane Library, CNKI and Wanfang databases. Relevant papers were identified and the effects of cortisol on cognitive and emotional disorders after stroke were analyzed by literature induction.
Results: Eighteen papers were included, including cross-sectional studies and cohort studies. The subjects suffered ischemic stroke or hemorrhagic stroke. Cortisol levels were measured from samples of blood, saliva or hair. Most patients showed increased basal cortisol levels and changes in cortisol circadian rhythms. Most studies report that patients with high cortisol levels on admission (acute phase of stroke) are more likely to experience cognitive decline and depression later in life.
Conclusions: Admission cortisol level may be a promising biomarker for predicting cognitive and emotional prognosis after stroke.

Chronic cerebral ischemia (CCI) is one of the most common forms of cerebrovascular disease, which affects a significant number of patients, often leading to disability, cognitive impairment and dementia. The analysis of modern data on the pathogenesis and risk factors for the development of CCI, as well as on the mechanisms of action of Mexidol on various links in the pathogenesis of CCI. A systematic search was conducted in the PubMed, MEDLINE and Google Scholar databases, on Russian and English-language sites with open access publications on the problem of CCI and on the drug Mexidol in the period from 2014 to 2024.

Eating disorders (EDs) are a group of debilitating mental illnesses characterized by maladaptive eating behaviors and severe cognitive-emotional dysfunction, directly affecting 1-3% of the population. Standard treatments are not effective in approximately one third of ED cases, representing the need for scientific advancement. There is emerging evidence for the safety and efficacy of psilocybin-assisted psychotherapy (PAP) to improve treatment outcomes in individuals with EDs.

Background: Low-value care is unnecessary care that contributes to inefficient use of health resources and constitutes a considerable proportion of healthcare expenditures worldwide. Factors contributing to patients' demand for low-value care have often been overlooked and are dispersed in the literature. Therefore, the current study aimed to systematically summarize factors associated with patients' demand for low-value care.

The perinatal period encompasses a critical window for neurodevelopment that renders the brain highly responsive to experience. Trauma, such as intimate partner violence (IPV) and early life stress/neglect, during this period negatively affects physical and mental health outcomes, including increasing ones risk for chronic pain. Although epigenetic programming likely contributes, the mechanisms that drive the relationship between perinatal trauma and adverse health outcomes, are not fully understood.

Background: In recent years, the adoption of large language model (LLM) applications, such as ChatGPT, has seen a significant surge, particularly among students. These artificial intelligence-driven tools offer unprecedented access to information and conversational assistance, which is reshaping the way students engage with academic content and manage the learning process. Despite the growing prevalence of LLMs and reliance on these technologies, there remains a notable gap in qualitative in-depth research examining the emotional and psychological effects of LLMs on users' mental well-being.
