概括
在正常范围内较低的自由三甲状腺素 (FT3) 水平与老年人认知功能较差有关. 这种关联在各种认知测试中观察到男性和女性,这表明甲状腺激素在维持认知健康方面可能发挥作用.
科学领域:
- 内分泌学 在内分泌学.
- 神经科学是一个神经科学.
- 老年学是指老年学的学科.
背景情况:
- 血清甲状腺激素水平甚至可以影响正常甲状腺状况 (euthyroid) 的个体的认知功能.
- 了解甲状腺激素和认知之间的关系对于老龄化人口至关重要,因为认知能力下降是一个重大问题.
研究的目的:
- 研究血清甲状腺激素水平与美国老年人 (≥60岁) 的认知功能之间的关联.
- 通过使用代表性的国家调查数据,分析与甲状腺激素水平相关的不同测试中的认知表现.
主要方法:
- 这是一项横截面研究,使用了2011-2012年国家健康和营养检查调查 (NHANES) 734名参与者的数据.
- 通过免疫酶分析评估甲状腺功能;使用CERAD-Word Learning,动物流利性测试和数字符号替代测试 (DSST) 测量认知功能.
- 使用权重多变量线性回归和二元逻辑回归分析来确定关联,控制共变量.
主要成果:
- 在老年人群中,自由三甲氨酸 (FT3) 与动物流利性测试和DSST的表现呈负相关性.
- 性别分层分析显示,FT3与男性和女性的认知测试之间存在负面关联.
- 更高的FT3水平 (Q3,Q4与Q1) 与明显增加的DSST性能受损的风险有关.
结论:
- 在正常范围的FT3水平和老年人的认知功能之间存在显著的反向关系,即使在调整共变量之后.
- 这些发现表明,FT3可能在维持老年人的认知功能方面发挥作用.
- 建议进行进一步的纵向研究,以确定甲状腺激素水平与认知功能之间的因果关系.

Functions of Thyroid Hormones
2.5K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones
4.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Cognitive Development During Adulthood
55
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,...

The Thyroid Gland
3.6K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Language and Cognition
325
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
