概括
与健康对照人群相比,恐慌症 (PD) 患者表现出工作记忆的缺陷和前额叶皮层活动的减少. 通过高通风引起的症状显示了PD个体的大脑激活变化受损,这表明神经机制发生了变化.
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.
- 认知心理学 认知心理学
背景情况:
- 大脑的低正面性与恐慌症 (PD) 病理生理学有关.
- 功能近红外光谱学 (fNIRS) 可以评估前额叶皮层 (PFC) 的活动.
研究的目的:
- 研究PD患者与健康对照 (HC) 患者在认知任务期间症状挑起对PFC活动的影响.
- 检查高通风前后的工作记忆性能和大脑激活模式.
主要方法:
- 在N-back任务期间,20名以前没有服用过药物的PD患者和20名HC患者接受了fnirs.
- 参与者执行过度通风前和后的任务.
- 双向重复测量ANOVA分析了任务性能和大脑激活变化.
主要成果:
- 与HC相比,PD参与者在双背任务上表现明显差.
- 在零回任务期间,在右前额前额区域 (RBA10,RBA8,RBA46) 和LBA8中发现了显著的时间 × 组相互作用.
- 在高通风后,HC组表现出比PD组更大的激活变化.
结论:
- 皮尔斯顿病与工作记忆缺陷和前额功能下降有关.
- 在PD患者中,与HC患者相比,PD患者中缺少右前额外脱活后高通风的情况表明,PD中右半球的参与发生了变化.

Hyperpnea and Hyperventilation
1.3K
Hyperventilation refers to a higher-than-normal rate and depth of breathing, often associated with anxiety attacks. This excessive breathing surpasses the body's need to expel CO2, leading to a condition known as hypocapnia - an unusually low level of carbon dioxide in the blood. Hypocapnia can constrict cerebral blood vessels, reducing blood flow to the brain, which may result in dizziness or fainting. Early signs include tingling and muscle spasms in the hands and face, caused by falling...

Panic Disorder
184
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
