刺激剂通过调节神经传递来优化注意力缺陷/多动障碍 (ADHD) 的大脑网络参与. 神经成像显示了急性益处,但长期影响需要进一步调查.
科学领域:
- 神经科学是一个神经科学.
- 心理药理学 心理药理学
- 放射学 放射学是一门学科.
背景情况:
- 兴奋剂是注意力缺陷/多动障碍 (ADHD) 的第一线治疗方法,有着深入研究的突触机制,但临床效益相关性不清楚.
- 了解刺激机制如何转化为临床效应对于优化ADHD治疗至关重要.
- 神经成像技术,包括核医学和MRI,为大脑中的刺激作用提供了洞察力.
研究的目的:
- 提供对ADHD中兴奋剂效应的全面审查,重点关注神经成像发现.
- 为了弥合兴奋剂的突触机制及其临床观察到的益处之间的差距.
- 综合当前关于刺激剂如何调节ADHD中大脑网络和神经传递的证据.
主要方法:
- 综合文献综述,重点关注核医学和磁共振成像 (MRI) 研究.
- 对多巴胺和上腺素神经传递的刺激作用的分析.
- 检查对与任务相关的大脑网络,感知突出性和默认模式网络的影响.
主要成果:
- 兴奋剂的使用调节多巴胺和上腺素,优化与任务相关的大脑网络,减少默认模式网络干扰.
- 急性兴奋剂效应可能会使ADHD患者的前额-状-状-大脑小脑网络变化正常化.
- 兴奋剂治疗对大脑功能的长期影响仍然存在争议,需要进一步研究.
结论:
- 神经成像显著提高了对ADHD刺激机制的理解.
- 目前的研究受限于样本规模小,随访时间短,方法异质.
- 未来的研究应该调查与年龄相关的影响,长期结果,兴奋剂之间的差异和治疗反应预测因素.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...

Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
