Attention-Deficit/Hyperactivity Disorder

109
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....

Disorders of the Nervous Tissue

1.4K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

139
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Cytoskeletal Coordination in Cell Migration01:32

Cytoskeletal Coordination in Cell Migration

4.8K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

164
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

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
  • 发动机控制器的控制器

背景情况:

  • 发育协调障碍 (DCD) 的特点是运动学习困难.
  • 新出现的证据表明,镜像神经系统 (MNS) 在DDC中起着作用.
  • 对于理解和执行行动,MNS活动至关重要.

研究的目的:

  • 调查患有DCD和没有DCD的儿童之间MNS活动的差异.
  • 在行动观察,执行和非行动基线期间检查MNS功能.
  • 探索MNS活动与同时发生的神经发育特征之间的关系.

主要方法:

  • 脑电图 (EEG) 测量了mu节奏,作为8-12岁儿童MNS激活的代理.
  • 参与者包括有 (n=20) 和没有 (n=19) DCD 的儿童.
  • 脑电图记录了休息期间的活动,观察/执行运动动作,以及非生物运动.

主要成果:

  • 没有DCD的儿童与DCD的儿童相比,表现出更大的mu节律脱同步 (更高的MNS活动).
  • 两组都显示了MNS活动的增加,从观察罚款行动到执行毛额行动.
  • 患有DCD的儿童在非生物运动观察期间减少了肌肉力量,与注意力和运动技能差异相关.

结论:

  • 患有DCD的儿童的MNS显示特异性降低,无法区分生物和非生物运动.
  • 这种MNS非典型性可能是DCD中观察到的运动障碍的基础.
  • 不同的MNS活动可能表明DDC中的更广泛的非典型感知网络功能.
