Understanding OXT-DA interaction offers important insights into the neurobiological mechanisms underlying both healthy and pathological social functioning.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"78 ","pages":"Article 101200"},"PeriodicalIF":6.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144340001","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}

These issues also exhibit notable sex differences: males tend to show higher prevalence, while females, though less affected overall, often face more severe outcomes. Despite these public health and personal costs, research on externalizing problems in females remains limited, particularly regarding the biological and hormonal factors driving these sex differences. The current paper explores how female hormonal influences across developmental stages may affect externalizing behaviors, highlighting the role ovarian hormones may play in shaping these externalizing problems. During puberty, estradiol and progesterone shifts contribute to risk-taking behaviors in females, who show distinct vulnerability patterns from males. Other important and understudied reproductive periods include puberty, pregnancy and postpartum, and perimenopause and menopause, and the menstrual cycle, overall. However, most population-level studies overlook the role of ovarian hormone fluctuations. This review advocates for the integration of hormonal phases in assessments, as hormonal shifts may exacerbate symptoms or modify treatment responses. Cycle-aligned interventions and hormone stabilization strategies could improve treatment outcomes, addressing gaps in male-focused treatment models and enhancing care for females with these disorders.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"78 ","pages":"Article 101206"},"PeriodicalIF":6.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722236","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}

The aging female brain represents a unique substrate for alcohol effects, given that both the HPG and HPA undergo significant changes with aging in women, making this demographic notably different from both males and younger females. Little attention has been directed at alcohol effects in this group but changing trends in women’s drinking have brought these issues to the forefront. Major gaps in our understanding of aging females include how stressors common to middle and older aged women impact alcohol consumption, and how alcohol consumption in older women impacts brain health and aging. Thus, here we review the current state of knowledge concerning the unique neuroendocrinology of aging females, their stressors and pharmacokinetic reactions to alcohol, and their interactions as causes and neurotoxic consequences of excessive alcohol drinking. We highlight the role of the neuroimmune system at the intersection of aging, alcohol and stress effects, and brain endocrine systems. We conclude that therapeutic interventions should be aimed at managing alcohol-induced neuroimmune responses and their downstream effects on vulnerable white matter. In addition, mid-life represents a window of opportunity in which to introduce strategies to limit alcohol consumption and its consequences for the aging female brain. As so little is known about how alcohol intake impacts brain health in females, let alone in aging females, we assert the need for further investigation of middle-aged and aged females in human and preclinical studies.</div></div>","PeriodicalId":12469,"journal":{"name":"Frontiers in Neuroendocrinology","volume":"78 ","pages":"Article 101201"},"PeriodicalIF":6.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144230014","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}
