- 眼科医生 眼科 眼科
背景情况:
- 抗精神病药物诱导的眼动改变在精神分裂症中已知,但在临床高风险 (CHR) 阶段没有表征.
- 这项研究调查了CHR个体对眼动的短期抗精神病作用及其临床结果的关联.
研究的目的:
- 检查两个月的抗精神病治疗对CHR个体眼动参数的影响.
- 评估这些眼动变化与长期临床缓解状态之间的关联.
主要方法:
- 一项纵向队列研究,涉及139名CHR个体和105名健康对照.
- 眼睛追踪评估了固定稳定性,自由观看和顺的追逐;参与者被跟踪了三年,以了解缓解状态.
- 线性混合效应模型和随机森林模型分析了治疗效应和眼动变化的预测值.

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.

01:21Antipsychotic Drugs: Typical and Atypical Agents
762
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

01:26Psychosis: Goals of Pharmacotherapy
474
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.
