概括
抑郁症在老年人中显著影响主观认知衰退 (SCD). 较高的抑郁症状削弱了执行功能和认知投诉之间的联系,强调了在SCD评估中需要进行抑郁查的必要性.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 精神病学是一个精神病学.
背景情况:
- 执行功能障碍 (EF) 可能是神经退行性疾病的早期指标,尽管客观检测具有挑战性.
- 主观认知衰退 (SCD) 可能反映出微妙的EF缺陷,但也受到抑郁症的影响.
- 抑郁症状对EF和SCD之间关系的缓解作用尚不清楚.
研究的目的:
- 调查抑郁症状是否能缓和执行功能与主观认知衰退 (SCD) 之间的关联.
- 检查执行功能 (EFs),抑郁症状和老年人自我报告的认知困难之间的相互作用.
主要方法:
- 一项涉及65名门诊患者的横截面研究,评估执行功能 (FAB),主观认知困难 (CFI自我报告) 和抑郁症状 (PHQ-9).
- 用PHQ-9分数作为FAB和CFI自我报告之间的关系的调节器进行了调节分析.
主要成果:
- 参与者表现出保存的EF,轻度抑郁症状和适度的主观认知困难.
- 抑郁症状 (PHQ-9) 显著预测主观认知困难 (CFI),而执行功能 (FAB) 则没有.
- 一个显著的相互作用效应表明,EF和SCD之间的关联仅在低抑郁水平时是积极的,随着抑郁症的增加而变得无意义和负面.
结论:
- 在患有SCD的个体中,抑郁症状与主观认知抱怨比执行功能更强烈相关.
- 较高的抑郁水平调节了执行功能和认知问题之间的关系,可能会减少或逆转它.
- 建议将抑郁症状的查和治疗纳入SCD评估和护理.

Cognitive Development During Adulthood
740
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,...

Alzheimer's Disease: Overview
1.6K
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...

The Influence of Cognition on Affect
170
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Dementia

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.

Depressive Disorders: Etiology
408
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
