概括
肺动脉高血压 (PAH) 与抑郁,焦虑或认知能力下降没有因果关系. 然而,PAH在特定区域影响大脑皮层厚度,提供了有关神经精神病症状的见解.
科学领域:
- 神经科学是一个神经科学.
- 心脏病学 心脏病学
- 遗传学 是一个遗传学.
背景情况:
- 肺动脉高血压 (PAH) 经常与焦虑,抑郁和认知恶化等神经精神症状有关.
- 观察性研究表明,PAH患者的大脑皮层的结构变化.
研究的目的:
- 研究遗传决定性肺动脉高血压 (PAH) 与认知表现,抑郁,焦虑以及大脑皮质结构的改变之间的潜在因果关系.
- 使用两个样本的门德尔随机化方法来评估这些关联.
主要方法:
- 来自162,962名欧洲人的全基因组关联研究 (GWAS) 数据被用于识别PAH的遗传变异.
- 使用PAH,认知表现,抑郁,焦虑和大脑皮层表面积 (SA) 和厚度 (TH) 的总结统计数据进行了门德尔随机化分析.
- 进行了敏感性分析,包括科克兰的Q测试和MR-Egger拦截,以评估异质性和性.

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Depressive Disorders: Etiology
78
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Stress and Mental Health
149
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Panic Disorder
110
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Psychoneuroimmunology: Cardiovascular Disease
30
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Attention-Deficit/Hyperactivity Disorder
57
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....
