Hormonal fluctuations across a woman’s lifespan, including those naturally occurring during puberty, pregnancy, and menopause, as well as exposures to exogenous hormones, such as oral contraceptives, assisted reproductive technologies, and hormonal replacement therapies, profoundly influence neurobiological pathways, potentially modulating both stroke risk and subsequent depressive disorders. Female-specific or female-predominant patient factors, including polycystic ovary syndrome, migraine, autoimmune disease, and breast cancer may exacerbate susceptibility to depression after stroke. Behavioral factors, such as smoking, substance use, and stress, further interact with biological predispositions to impact PSD outcomes. Our review presents current evidence on the intersection of hormonal fluctuations, patient factors, and behavioral influences in shaping the stroke risk and manifestation of PSD in women. Addressing the intersecting influences on PSD offers a promising pathway to improve post-stroke mental health outcomes and enhance quality of life for women.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"80 ","pages":"Article 101232"},"PeriodicalIF":6.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146017811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While it is suggested that these reproductive subtypes present as a stable trait, it remains unclear whether they share an underlying genetic architecture. In this review, we summarize the known genetic etiology of each reproductive subtype of depression, contrast the findings between subtypes, and highlight existing knowledge gaps, challenges, and ways forward. We found that while postpartum depression has been comparatively more studied, genetic studies on premenstrual dysphoric disorder and perimenopausal depression are scarce. Candidate genes commonly studied in major depressive disorder (<em>5-HTT, COMT, MAO-A,</em> and <em>TPH1</em>) as well as <em>ESR1</em> have been studied across the reproductive subtypes, however, showing inconsistent patterns. No genome-wide association studies currently exist for premenstrual dysphoric disorder or perimenopausal depression. Genome-wide association studies on postpartum depression, although underpowered, point to unique and shared genetic components with other psychiatric disorders, which should be further explored across all reproductive subtypes of depression. To advance this field, well-powered studies with consistent diagnostic criteria across diverse ancestry groups are needed. Identifying whether overlap exists in the genetic architecture of premenstrual dysphoric disorder, postpartum depression, and perimenopausal depression could enhance our understanding of their pathogenesis and foster the development of new therapeutic targets.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"80 ","pages":"Article 101230"},"PeriodicalIF":6.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145780420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although sex differences in responses to cannabis have been reported, no systematic review has examined whether these extend to acute cognitive effects. Our primary aim was to examine sex differences in the acute effects of cannabis (including isolated delta-9-tetrahydrocannabinol [THC]) on cognition in humans. Our secondary aim was to determine if sex differences in the acute effects of cannabis vary by cognitive domain, route of administration, or dosing paradigm. Following PRISMA guidelines, we conducted a comprehensive literature search across Embase, MEDLINE, APA PsycInfo, Cochrane Library, and Web of Science databases. Of 1,625 unique records, 169 underwent full-text screening, and 29 studies met inclusion criteria. Six of 29 articles (20.7 %), representing eight of 216 cognitive outcomes (3.7 %), found statistical evidence of sex differences in acute cognitive effects of cannabis/THC. All six found increased effects in female participants in at least one cognitive variable; one study additionally found increased effects in male participants, and one study found divergent cognitive effects in male and female participants. There were no clear patterns by cannabis dosing paradigm, route of administration, or cognitive domain. Overall, we found limited evidence that sex significantly influences the acute cognitive effects of cannabis, though methodological heterogeneity precludes any firm conclusions. Future studies should prioritize the measurement of sex-related factors, such as hormonal modulation of cannabinoid pharmacokinetics and pharmacodynamics.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"79 ","pages":"Article 101215"},"PeriodicalIF":6.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144865676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evolutionarily, DNES traces to primitive metazoans where single cells combined neural and immune roles, later diversifying into specialized vertebrate NE cells. Hallmark traits include dense-core granules, amine metabolism, “salt-and-pepper” chromatin, and regulation by ASCL1, NEUROG3, and INSM1. Remarkable plasticity allows immune and epithelial cells to acquire NE features under stress, while carcinomas exploit this program to form aggressive neuroendocrine tumors (NETs) and resist therapy. Canonical neuroimmune circuits, the Vagus-driven inflammatory reflex and hypothalamic–pituitary–adrenal stress axis, illustrate DNES coordination of systemic responses. Clinically, DNES-derived neoplasms span multiple organs, produce diverse hormonal syndromes, and are managed with somatostatin analogues, epigenetic drugs, and emerging immunotherapies. Recognizing DNES as a diffuse, integrative regulatory network clarifies mechanisms of chronic inflammation and cancer evolution and offers novel therapeutic entry points for disorders ranging from asthma to pancreatic neuroendocrine carcinomas.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"79 ","pages":"Article 101216"},"PeriodicalIF":6.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144913485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
