短期暴露于一氧化碳 (CO) 空气污染与老年人,尤其是阿尔茨海默病患者的认知功能恶化有关. 这凸显了改善空气质量的必要性,
科学领域:
- 环境健康
- 神经科学
- 公共卫生
背景情况:
- 环境空气污染对全球健康构成威胁.
- 空气污染对神经退行性疾病的短期影响尚不清楚.
研究的目的:
- 研究轻度认知障碍 (MCI) 或阿尔茨海默病 (AD) 的老年人短期暴露和认知变化之间的关联.
主要方法:
- 使用了717名韩国MCI或AD患者的数据.
- 根据居住地与空气监测站的近距离进行反向距离加权估计的CO暴露 (1天到1个月的暴露).
- 使用迷你心理状态检查 (MMSE) 评估认知表现,并通过概括估计方程分析变化.
主要成果:
- 较高的7天平均CO暴露与较低的MMSE得分相关 (RR为0.89).

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
206
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.

Cognitive Development During Adulthood
255
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Negative and Cognitive Symptoms of Schizophrenia
120
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Role of Neurotransmitters in Memory
964
Neurotransmitters are integral to the brain's communication system, enabling neurons to transmit signals across synapses. This chemical exchange underpins various cognitive functions, including memory processes. The role of neurotransmitters in memory is multifaceted, influencing the encoding, consolidation, and retrieval of memories through their action on different neural circuits.
