概括
轻度认知障碍 (aMCI) 涉及免疫系统的变化,神经保护性细胞因子减少,神经毒性化学因子增加. 这些免疫特征,不包括抑郁症,是理解aMCI进展的关键.
科学领域:
- 神经科学是一个神经科学.
- 免疫学 免疫学 免疫学
- 老年学是一门学科.
背景情况:
- 虽然已经观察到免疫系统的激活,但amnestic轻度认知障碍 (aMCI) 的根本原因仍然不清楚.
- 以前的研究表明,免疫失调在认知衰退中的潜在作用.
研究的目的:
- 研究aMCI患者的细胞因子网络,特别是排除患有重大抑郁症 (MDD) 患者.

Alzheimer's Disease: Overview
451
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
106
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.

Negative and Cognitive Symptoms of Schizophrenia
44
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
466
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.
