概括
童年虐待并没有直接影响休息时的下丘脑-垂体-上腺 (HPA) 轴活动. 然而,这种关联因虐待报告方式和群体之间的社会经济差异而有所不同.
科学领域:
- 神经科学是一个神经科学.
- 发展心理学 发展心理学
- 儿童健康 儿童健康
背景情况:
- 童年虐待与不良的发育和健康结果有关.
- 这可能源于压力反应系统的失调,例如下丘脑-垂体-上腺 (HPA) 轴.
- 了解HPA轴的作用对于解决虐待的长期影响至关重要.
研究的目的:
- 进行关于儿童虐待和儿童休息HPA轴活动的第一个元分析.
- 调查可能解释这种关联中异质性的"第三个变量".
- 为了澄清早期生活压力和神经内分泌功能之间的复杂关系.
主要方法:
- 18项涉及2216名儿童的研究的元分析.
- 对受虐待儿童与未受虐待儿童的静止HPA轴活动的检查.
- 统计分析以确定虐待和HPA轴的调节者.
主要成果:
- 在受虐待和未受虐待的儿童之间,休息时的HPA轴活性没有总体差异 (SMD = 0.04).
- 在研究中观察到显著的异质性 (I2 = 58.60%,p = 0.001).
- 这种关联因虐待信息来源 (B = 0.33,p = 0.002) 和社会经济地位差异 (B = 0.39,p = 0.037) 而受到缓解.
结论:
- 童年虐待与休息HPA轴活动之间的直接联系并不总是显著的.
- 异质性表明,诸如报告方法和社会经济地位之类的上下文因素至关重要.
- 未来的研究应该考虑这些调节者,以更好地了解虐待对HPA轴调节的影响.

Hypothalamic-Pituitary Axis
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.
Adrenal Gland Disorders
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Physiological Foundation of Stress
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.

Attention-Deficit/Hyperactivity Disorder
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.

Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
