概括
发育协调障碍 (DCD) 和大脑视觉障碍 (CVI) 分享重叠的症状,但不同的视觉和认知特征可以帮助区分它们. 临床医生应在患有DCD且表现出特定视觉和运动缺陷的儿童中查CVI.
科学领域:
- 儿科神经学 儿科神经学
- 发展心理学是发展心理学.
- 眼科医生 眼科 眼科
背景情况:
- 发育协调障碍 (DCD) 和脑视觉障碍 (CVI) 在视觉运动整合和感知能力方面存在重叠的挑战.
- 由于不同的管理策略,区分DCD和CVI具有临床意义.
- 这项研究研究了儿童中DCD和CVI之间的共同和独特特征.
研究的目的:
- 确定患有DCD和CVI的儿童之间临床,神经心理和功能视觉技能的趋同和分歧.
- 为区分这两种神经发育条件提供见解.
主要方法:
- 对65名患有DCD的儿童和35名患有CVI的儿童进行了神经心理评估 (认知,视觉认知,运动协调) 和视觉敏度测试.
- 使用CVI-Inventory (CVI-I) 评估功能视力问题并对参与者进行分类.
- 在DCD和CVI组之间进行了比较分析.
主要成果:
- 两组之间在视觉注意力,视觉感知,全球运动协调或视觉构造得分方面没有发现显著差异.
- 患有CVI的儿童通常表现出较低的智力,视觉,视觉认知和运动能力.
- CVI-I确定了特定的功能视觉问题,有助于集群受试者,区分那些具有更严重的神经心理特征的人 (主要是CVI) 和那些主要是DCD的人.
结论:
- 发育协调障碍和大脑视觉障碍有共同点,但也有不同的特征.
- 临床医生应考虑对患有DCD的儿童进行CVI查,这些儿童的视力敏度低,智商低,视觉运动整合缺陷显著,以及精细运动/平衡困难.
- 功能视觉评估对于区分DCD和CVI至关重要.

Learning Disabilities
68
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Language and Cognition
291
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Intellectual Disability
17
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Photoreceptors and Visual Pathways
5.5K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Visual Agnosia
165
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Autism Spectrum Disorder
34
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.
