概括
血管与大脑的关联在青少年中很明显,视网膜血管口径与大脑结构有关. 优化心血管健康可能有利于青少年的大脑发育,特别是在双相情感障碍 (BD) 中.
科学领域:
- 神经科学是一个神经科学.
- 心血管科学 心血管科学
- 青少年精神病学 青少年精神病学
背景情况:
- 血管与大脑的关联已在成年人中确立,但在青少年中未得到充分研究,特别是那些患有双相情感障碍 (BD) 等精神疾病的青少年.
- 患有BD的青少年面临心血管风险增加,需要对血管对大脑发育的影响进行调查.
- 视网膜血管口径为系统血管健康及其与大脑相关的系统血管健康提供了一个非侵入性窗口.
研究的目的:
- 为了调查视网膜血管口径和BD和无BD的青少年的区域大脑结构之间的联系.
- 探索患有BD的青少年与健康对照 (HC) 之间的这些血管-大脑关系中的潜在差异.
主要方法:
- 103名青少年 (51名BD,52名HC) 接受了视网膜底部成像,以检测动脉和静脉直径和脑结构的3特斯拉MRI.
- 兴趣区域 (ROI) 和顶点分析检查了特定的大脑区域 (vlPFC,vmPFC,ACC,杏仁体,海马体).
- 线性回归评估了视网膜测量和大脑结构之间的关联,控制年龄,性别,BMI和内体积.
主要成果:
- 在整体样本中,动脉口径和前带皮层 (ACC) 体积和表面积之间发现了负相关性.
- 动脉静脉比率 (AVR) 显示出与体积和表面积的显著积极关联,包括面状中额头,带状皮质和前皮质在内的区域.
- 一个显著的相互作用显示,较大的AVR与BD青少年的特定区域的较低大脑体积更强烈地相关,与HC相比.
结论:
- 血管-大脑关联在青春期存在,突出显示了优化心血管健康对大脑发育的潜在益处.
- 研究结果表明,血管健康可能是大脑结构的关键因素,特别是在精神病患者群体中,如患有BD.
- 需要进一步的研究来确定血管-大脑关联明显的子群体,以指导有针对性的干预.

Bipolar Disorder
108
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Attention-Deficit/Hyperactivity Disorder
132
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
