危险心理状态中与自闭症谱系相关的特征不匹配的特征
在PubMed上查看摘要
概括
此摘要是机器生成的。患有自闭症谱系障碍 (ASD) 风险的个体表现出明显的听觉处理模式. 具有高自闭症特征的高风险精神状态 (ARMS) 个体中较短的频率偏差负面性 (fMMN) 延迟可能作为客观标志物.
科学领域
- 神经科学
- 精神病学
- 临床心理学
背景情况
- 区分自闭症谱系障碍 (ASD) 和精神分裂症谱系障碍 (SSD) 是一个挑战,特别是在患有精神病风险的个体 (ARMS) 中.
- 需要客观标记来区分这些情况并指导干预.
研究的目的
- 调查与没有自闭症特征的ARMS个体之间的不匹配负面性 (MMN) 模式的差异.
- 探索MMN作为ARMS个体中ASD特征的潜在客观标志物.
主要方法
- 使用自闭症谱系系数日本版本 (AQ-J) 评估了49名ARMS患者和45名健康对照.
- 听觉奇怪模式 (持续偏差和频率偏差) 用于记录脑电图 (EEG) 和分析MMN.
- 基于AQ-J得分的ARMS亚组进行了对比,对MMN幅度和延迟的群体差异进行了比较.
主要成果
- 在整体ARMS组和健康对照组之间没有发现显著的MMN差异.
- 与具有较低ASD特征的人相比,具有高ASD特征 (AQ(+)) 的ARMS个体表现出明显较短的频率偏差MMN (fMMN) 延迟.
- 在ARMS组中,观察到fMMN延迟和总AQ-J分数,特别是Communication分量之间存在负相关性.
结论
- 在ARMS个体中,较高的ASD特征与fMMN延迟时间的缩短有关.
- MMN 延迟,特别是 fMMN,可以作为一个客观的生物标志物来识别 ARMS 个体的潜在自闭症特征.
- 这一发现可能有助于为具有伴随自闭症特征的精神病风险的个体量身定制干预措施.

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.
