概括

卵泡刺激激素 (FSH) 水平升高,而不是雌激素,与绝经后妇女的认知衰退和阿尔茨海默氏症 (AD) 病理学有关. 较高的FSH与增加的粉样β沉积和较差的认知功能相关.

科学领域:

神经科学是一个神经科学.
内分泌学在内分泌学.
老年学是一门学科.

背景情况:

与男性相比,女性患阿尔茨海默病 (AD) 的风险更高.
更年期期间的荷尔蒙变化与此有关,但它们在阿尔茨海默病理和认知功能中的确切作用尚不清楚.

研究的目的:

研究血清毛囊刺激激素 (FSH) 和雌醇水平与经更年期妇女的认知功能和大脑粉样β (Aβ) 沉积之间的关联.
为了区分这些激素在认知健康的范围内的影响,从正常的衰老到AD痴呆症.

主要方法:

研究包括884名60岁及以上的绝经后妇女.
参与者被分为认知正常 (CN),轻度认知障碍 (MCI) 和AD痴呆症组.
大脑Aβ沉积量化使用粉样质子发射断层扫描 (PET).

主要成果:

较高的FSH水平与较差的认知表现和增加的大脑Aβ沉积有显著的关联.
在患有AD痴呆症,MCI和CN群的妇女中,FSH水平逐渐上升.
雌激素水平与认知结果或Aβ负担没有显著的关联;FSH对认知的影响是由Aβ沉积的介导.

结论:

高水平的FSH,而不是低水平的雌激素,与绝经后妇女的认知衰退和Aβ病理有关.
在老年女性中,FSH可能是大脑Aβ沉积和随后认知能力下降的重要危险因素.
需要进一步的研究来探索AD的潜在机制和潜在的荷尔蒙干预措施.

Types of Hormones

Types of Hormones

Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Types of Hormones

Types of Hormones

Hormones are classified into four main groups: steroids, eicosanoids, amino acid-based derivatives, and peptide hormones.
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Hormonal Regulation

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Amyloid Fibrils

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Magnetic Declination

Magnetic Declination

Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...
