We examine how exercise stimulates brain-derived neurotrophic factor (BDNF), regulates monoaminergic systems (serotonin, dopamine, norepinephrine), modulates inflammatory and oxidative stress pathways, and promotes neurogenesis and synaptic plasticity. The review also explores systemic mechanisms including the gut–brain axis, myokine signaling (e.g., irisin, cathepsin B), and the regulation of the hypothalamic–pituitary–adrenal (HPA) axis. Furthermore, we discuss how exercise influences key psychological mechanisms, including emotion regulation, self-efficacy, and cognitive reappraisal, offering a translational bridge between physiology and psychotherapy. Understanding these overlapping mechanisms can guide clinicians in prescribing exercise as an evidence-based adjunct or standalone therapy for mental health disorders.

In fact, neuroinflammation is considered as one of the key pathological factors of neuronal dysfunction leading to dementia in AD and other forms of dementias or related dementias (RD). Central nervous system (CNS) network communicates and control the immune system signaling pathways within the brain as well as peripheral part of the body. Hence, disturbance in the physiological immune system regulation is susceptible to the etiology or pathogenesis of the diseases. Microglia, astrocytes, oligodendrocytes, B-/T-cells and neutrophils are potential regulatory cells in keeping our immune system in balance. The imbalance in the regulatory function of these cells results to inflammatory consequences and has direct or indirect influence in the AD trajectory. In the brain, neuroinflammation is strongly linked to the accumulation of Aβ plaques and tau tangles which lead to pathogenesis underlying dementia of AD. Currently, neuroinflammation is considered as one of the pathological hallmarks of AD, alongside Aβ plaques and tau tangles. Various research and review articles have described the dysregulation of immune system cells leading to neuroinflammation in AD and RD pathogenesis. However, how these immune cells become coordinately imbalanced in the disease pathogenesis has been rarely reported, which is necessary for deeper understanding of the disease pathology and therapeutic development. In this review, we intend to highlight and discuss the neuroinflammatory pathways mediated via dysregulation of microglia, astrocyte, oligodendrocyte, neutrophil, B-cell and T-cell functions, which leads to neuronal dysfunction, dementia or cognitive decline in AD and RD.

Fewer studies have examined predictors of <em>suicide</em> within an extensive longitudinal frame, which is problematic since findings from studies including participants with non-lethal suicidal behavior are not easily generalizable to patients that complete suicide. We aimed to address this gap by examining demographic and clinical factors as predictors of suicide in a longitudinal prospective cohort study of 7,000 consecutively admitted patients. Mean observation time was 4.1 years. Male gender, more frequent admissions during the follow-up period, and having SI, DSH and substance-induced psychosis at the final admission before suicide, <em>directly</em> predicted <em>shorter</em> time to suicide. Shorter time to suicide was <em>indirectly</em> predicted by borderline personality disorder (BPD) via DSH and by psychotic depression and neurotic disorders via SI. In contrast, <em>longer</em> time to suicide was <em>indirectly</em> predicted by substance-induced psychosis and psychotic disorders via reduced probability of SI and DSH at the final admission. Patients diagnosed with BPD had more frequent admissions and higher levels of SI and DSH across admissions, which predicted shorter time to suicide via increased risk of DSH at the final admission. Similarly, patients diagnosed with neurotic disorders had a higher level of SI and DSH across admissions, with shorter time to suicide via SI and DSH at the final admission. Findings suggest different pathways to suicide for different clinical subgroups, and this is discussed in relation to current theoretical models that emphasize suicide as a transdiagnostic phenomenon.</div></div>","PeriodicalId":16868,"journal":{"name":"Journal of psychiatric research","volume":"195 ","pages":"Pages 257-263"},"PeriodicalIF":3.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146125251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
