概括
精神分裂症患者表现出大脑活动模式的改变,特别是EEG微状态C和D. 这些微状态变化与症状严重程度有关,并预测抗精神病治疗的反应.
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.
- 生物医学工程 生物医学工程
背景情况:
- 电脑电图 (EEG) 微态是短暂的,准稳定的头皮拓图,反映了整个大脑的电潜力.
- 在精神分裂症各个阶段都观察到EEG微状态的变化,微状态C的增加和微状态D的减少与异常突出相关.
研究的目的:
- 在精神分裂症的各种症状领域中调查EEG微态动态和疾病严重程度之间的关系.
- 为了确定微观状态的变化是否预测对抗精神病治疗的反应.
主要方法:
- 45名精神分裂症住院患者接受了临床评估和静止状态EEG记录 (128个电极) 以评估微态AE.
- 40名患者在6周后被重新评估,以确定治疗反应.
- 为了进行比较,包括31个健康对照组.
主要成果:
- 负症状严重程度与微状态C的时间覆盖和持续时间负相关.
- 与非响应者相比,治疗响应者表现出较大的微状态C时间覆盖,持续时间和全球解释变异 (GEV).
- 受访者还显示了微状态D发生的减少和微状态E动态的改变 (时间覆盖,发生,GEV).
结论:
- 这些发现支持了微状态C和D不平衡是精神分裂症的关键病理生理机制的假设.
- 微状态动态,特别是CD失衡和微状态E,与负面症状有关,并预测抗精神病治疗反应.

Psychosis: Goals of Pharmacotherapy
209
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Psychosis and Antipsychotic Drugs: Overview
455
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...
