概括
主观认知衰退 (SCD) 可能是痴呆症的前身,但APOE ε4以外的遗传风险尚不清楚. 需要对其他基因和多基因风险评分进行进一步的研究,以了解SCD的遗传基础.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 老年学是指老年学的学科.
背景情况:
- 主观认知衰退 (SCD) 是痴呆症的潜在早期指标.
- 遗传倾向,包括Apolipoprotein (APOE) ε4等位基因,有助于SCD风险.
- 除了APOE ε4之外,影响SCD的遗传因素需要进一步调查.
研究的目的:
- 系统地审查与SCD相关的遗传因素,不包括APOE ε4等位基因.
- 提高对主观认知衰退的遗传基础的理解.
- 为了确定SCD的遗传倾向的研究差距.
主要方法:
- 在PubMed/MEDLINE和Embase.进行了PRISMA系统的文献搜索.
- 关键词包括"主观认知衰退"和"遗传倾向".
- 从270个已识别的文章中,包括16项研究进行定性分析.
主要成果:
- 在八项研究中,阿尔茨海默病 (AD) 的家族病史显示了与SCD的冲突关联.
- 除了APOE ε4之外,研究了其他基因的六项研究提供了不确定的结果.
- 关于AD和SCD的多基因风险得分之间的关联存在有限的数据.
结论:
- 目前关于超出APOE ε4的SCD遗传因素的证据不足.
- 需要进一步的研究,以探索更多涉及AD的基因范围.
- 多基因风险评分对未来对SCD遗传学的研究有希望.

Alzheimer's Disease: Overview
469
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...

Human Genetics
566
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Dementia
113
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

Alzheimer's Disease: Treatment
184
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
