概括
在早期精神病患者中,抗精神病药物可以导致与不良的冲动控制和大脑网络变化相关的快速体重增加. 这些影响与炎症有关,与健康个体不同.
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.
- 医疗成像医学成像
背景情况:
- 抗精神病药物 (AP) 对于治疗精神病至关重要,但通常会引起显著的体重增加.
- 这种体重增加是不可预测的,并具有广泛的健康后果,需要对潜在机制进行研究.
- 识别患有AP诱导体重增加风险的患者对于个性化治疗策略至关重要.
研究的目的:
- 为了研究与早期精神病中抗精神病药物诱导的体重增加相关的脑系统水平过程.
- 探索大脑解剖学,功能连接,冲动性和体重增加患者的炎症之间的联系.
- 为了区分这些效应与健康个体观察到的效应.
主要方法:
- 磁共振成像 (MRI) 用于评估早期精神病患者的大脑解剖学和功能连接.
- 收集了人类计量数据 (体重增加) 和冲动控制得分.
- 分析对比了高体重增加 (一个月≥5%) 与低体重增加 (<5%) 的患者,并包括健康的对照队列.
主要成果:
- 在早期精神病患者中,较高的体重增加与较差的冲动控制和改变的大脑结构相关 (额头灰质减少,条纹体积增加).
- 在体重显著增加的患者中,前-状功能连接被破坏.
- 体重增加与炎症生物标志物等离子素激活剂抑制剂-1.0相关.
- 在健康的年轻人和中年人中没有发现任何显著的关联.
结论:
- 接受抗精神病治疗的精神病患者的体重增加与冲动控制受损以及与冲动性相关的大脑网络的特定变化有关.
- 神经炎症过程可能在调解这些影响方面发挥作用.
- 研究结果强调需要监测抗精神病药物诱导体重增加的风险患者的大脑变化和炎症.

Antidepressant Drugs: MAOIs and Other Agents
228
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Psychosis: Goals of Pharmacotherapy
125
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
248
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...

Attention-Deficit/Hyperactivity Disorder
59
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....

Antipsychotic Drugs: Typical and Atypical Agents
194
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...

Regulation of Food Intake
228
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
