概括

儿科双极性障碍 (PBD) 显示大脑小脑功能连接的改变,特别是在抑郁阶段. 小脑中的这些变化可能为PBD提供了洞察力.

科学领域:

神经科学是一个神经科学.
精神病学是一个精神病学.
放射学放射学是指放射学

背景情况:

儿科双极性障碍 (PBD) 是一种复杂的精神疾病.
小脑在PBD中的作用尚未完全理解.
多模式磁共振成像 (MRI) 可以揭示大脑的变化.

研究的目的:

在患有双相情感障碍 (PBD) 的儿科患者中研究小脑子子区域的结构和功能变化.
探索PBD中这些小脑变化的临床意义.
阐明小脑在PBD病理生理学的特定作用.

主要方法:

48名患有PBD (抑郁期) 的儿科患者和22名健康对照 (HCs) 接受了3.0T休息状态功能性MRI (rs-fMRI).
临床评估包括汉密尔顿抑郁量表 (HAMD) 和青年躁狂评分量表 (YMRS).
用34个小脑子子区域作为种子点来分析全脑功能连接 (FC).

主要成果:

PBD患者在特定的大脑小叶和其他大脑区域之间表现出降低的FC,包括叶,额头,牙状核.
在大脑小肠VI和前额下层轨道环之间观察到降低FC.
在左牙核和前额叶皮层之间,以及左舌环之间,观察到改变的FC.

结论:

小脑与PBD中观察到的中枢神经重组有关.
在小脑子子区域内功能连接的改变表明它参与了PBD.
这些发现可能指导未来的PBD诊断和治疗目标开发.

Bipolar Disorder

Bipolar Disorder

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.

Cerebellum: Anatomical Regions

Cerebellum: Anatomical Regions

The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis....

Attention-Deficit/Hyperactivity Disorder

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....
