概括

通过激素治疗,包括避孕和更年期激素治疗,暴露于雌激素对老年妇女的认知功能有好处. 这项研究发现了与记忆和执行功能的积极关联,表明对认知能力下降的保护作用.

科学领域:

神经科学是一个神经科学.
内分泌学在内分泌学.
老年学是一门学科.

背景情况:

雌激素暴露中断,如手术更年期,与认知衰老和痴呆风险有关.
之前关于激素治疗和认知的研究显示出混合的结果,可能是由于有限的认知评估.
雌激素在整个生命周期的认知功能中的作用需要进一步研究,特别是关于不同形式的激素治疗.

研究的目的:

研究手术诱导的更年期 (卵巢切除术) 与认知表现之间的关联.
检查避孕和更年期激素治疗的时间和持续时间如何影响认知功能.
为了确定APOE4载体状态是否与卵巢切除和激素治疗在认知表现方面的相互作用.

主要方法:

在IGNITE研究中分析了461名绝经后妇女 (平均年龄69.6) 的基线数据.
对卵巢切除术和激素治疗 (避孕药,更年期激素治疗) 的评估.
认知评估使用蒙特利尔认知评估 (MoCA) 和详细的复合分数用于记忆,处理速度,执行功能和视觉空间处理.

主要成果:

在自然更年期之前的卵巢切除并没有与较差的认知表现有关.
激素治疗的使用与改善的情节性记忆,工作记忆和视觉空间处理有关.
使用避孕药与更好的MoCA分数,工作记忆和执行功能/注意力控制相关.

结论:

在成年期通过避孕和激素治疗暴露于雌激素对老年妇女的认知功能有好处.
这些发现强调了外源性雌激素对认知衰老的潜在保护作用.
需要进一步的研究来阐明连接终身雌激素暴露与晚年认知健康的因果机制.

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Environmental Influences on Intelligence

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...
