概括
精神分裂症患者表现出与异常大脑振荡相关的感官间注意力缺陷. 具体来说,感觉运动皮质中的β带活性变化与精神分裂症患者的症状严重程度相关.
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.
- 认知科学 认知科学
背景情况:
- 精神分裂症 (SZ) 与认知缺陷有关,包括注意力障碍.
- 感官间注意力,即能够整合来自不同感官的信息的能力,对于日常运作至关重要.
- 感官皮层的异常神经振荡与各种精神疾病有关.
研究的目的:
- 研究精神分裂症患者的感官间注意力缺陷和持续的神经振荡之间的关系.
- 在视觉触觉注意力任务期间检查视觉和感觉运动皮层的α和β波段振荡.
主要方法:
- 脑电图 (EEG) 用于记录27名精神分裂症患者和27名健康对照者的大脑活动.
- 参与者执行了一个视觉触觉目标检测任务.
- 分析的重点是特定皮质区域的α (8-12 Hz) 和下β (13-20 Hz) 波段振荡.
主要成果:
- 行为数据证实了精神分裂症患者的感官间注意力缺陷.
- 两组都在视觉皮层中增加了阿尔法波段振荡,当参与触觉刺激与视觉刺激时.
- 精神分裂症患者在感觉运动皮质内的β频段振荡中表现出额外的感官间注意力效应,与症状严重程度 (PANSS) 有负相关.
结论:
- 精神分裂症中感官间注意力缺陷与异常的神经振荡有关.

Negative and Cognitive Symptoms of Schizophrenia
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

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.
