概括
在儿童中,较大的乳头体积可能表明持续的强迫症症状 (OCS). 这一发现表明了潜在的神经发育联系,突出了儿童强迫症研究中需要进行纵向脑成像研究的需要.
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
- 儿科精神病学 儿科精神病学
背景情况:
- 之前的横截面研究表明,痴迷强迫症 (OCD) 儿童的乳头体积较大.
- 在老年人群中,这种胸膜扩大并未始终被观察到.
- 在一般人群中之前的研究发现,在9至12岁的儿童中,临床水平的强迫症症状 (OCS) 发现了更大的thalami.
研究的目的:
- 纵向研究胸膜体积,皮质成熟和儿童OCS的过程之间的关系.
- 检查基线 thalamic 体积是否预测了 OCS. 的持久性或变化.
- 探索与 thalamic 体积和皮质发展随着时间的推移之间的关联.
主要方法:
- 利用了基于人口的R世代研究的数据,包括2,552名接受1或2次MRI扫描的儿童 (9-12岁和13-16岁).
- 使用短暂强迫症查器 (SOCS) 评估了强迫症综合症,确定了可能的强迫症病例.
- 采用线性回归和线性混合效应模型来分析大脑形态和OCS之间的横截面和纵向关系.
主要成果:

Obsessive-Compulsive Disorder
54
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Attention-Deficit/Hyperactivity Disorder
44
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....

Longitudinal Research
11.9K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Psychosexual Stages of Personality: Anal
683
Sigmund Freud's theory of psychosexual development describes the anal stage as occurring between 18 months and three years of age. During this period, children derive pleasure from controlling and releasing their bowel movements. However, they quickly learn that societal expectations impose restrictions on when and where this can happen. This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...

Biological Causes of Schizophrenia
46
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
