今日文獻聚焦於BPD的生理機制（HPA軸）、共病特質（脆弱型自戀）、診斷障礙（青少年診斷猶豫）與共病遺傳架構，顯示趨勢正從單一心理治療轉向生物心理社會整合與早期干預。
Personality and mental health · Vulnerable Narcissism in Borderline Personality Disorder: Impact on Emotion Dysregulation, Identity Disturbance, and Rejection Sensitivity in Psychiatric Inpatients
發現BPD併發脆弱型自戀者情緒失調、身份擾亂與拒絕敏感度顯著加重，並伴隨更高自殺未遂與創傷暴露，凸顯需早期識別並針對此高風險亞群進行干預。
Personality and mental health · When Guidelines Are Not Enough: Clinician Hesitation to Diagnose Borderline Personality Disorder in Adolescents as a Barrier to Timely Evidence-Based Care.
儘管國際指南共識青少年BPD診斷與早期心理治療，但臨床醫師因污名化擔憂或認為診斷過早而遲疑診斷，導致青少年獲得碎片化照護，凸顯指南需從『何謂良好照護』轉為『為何無法執行』。
Journal of affective disorders · Mineralocorticoid receptor stimulation effects on stress-induced cortisol and alpha-amylase in female patients with borderline personality disorder and healthy controls: A randomized placebo-controlled experimental study.
BPD女性在應激時皮質醇反應遲鈍，但外源性糖皮質激素受體激動劑（氟氫可的松）使BPD與健康對照組皮質醇水平趨於一致，提示BPD的皮質醇遲鈍非主要由過度的MR介導負饋饋造成。
World psychiatry : official journal of the World Psychiatric Association (WPA) · Network analysis of the genetic relationships between twenty psychiatric and substance use disorders.
透過全瑞典人口基因風險評分網絡分析發現，BPD遺傳風險與自殺未遂、雙極性障礙、內化與外化症狀、飲食障礙具廣泛關聯，證實BPD為精神病理的跨診斷樞紐。
Brain, behavior, & immunity - health · The impact of mental health disorders in pregnancy on obstetric and neonatal outcomes: A narrative review.
雖以憂鬱為主的產前精神疾病研究眾多，但本文整合證據顯示BPD等較少被研究的精神疾病亦與高血壓、早產、胎兒生長異常及新生兒併發症風險增加相關，提醒產前照護需擴大精神疾病範疇。
