概括
晚年情绪障碍 (LLMDs) 可能是痴呆症的前身. 这项研究发现,LLMD患者的tau和粉样蛋白病理率较高,这表明这些神经退行性标志物是某些情绪障碍病例的基础.
科学领域:
- 神经科学是一个神经科学.
- 神经病理学神经病理学
- 老年精神病学是一门精神病学专业.
背景情况:
- 晚年情绪障碍 (LLMDs) 可能是神经退行性痴呆症的早期迹象.
- 包括抑郁症和双相情感障碍在内的LLMDs的潜在神经病理学尚不清楚.
- 调查阿尔茨海默病 (AD) 和非AD病理对于了解LLMDs至关重要.
研究的目的:
- 在LLMD患者中调查阿尔茨海默病 (AD) 和非AD tau病理之间的关联.
- 为了确定tau和粉样β (Aβ) 定子发射断层扫描 (PET) 发现是否与LLMDs的神经病理变化相关.
主要方法:
- 在52名LLMD参与者和47名健康对照者 (HCs) 中利用tau和粉样β (Aβ) PET成像 (F-florzolotau和C-Pittsburgh化合物B).
- 在208例不同神经退行性疾病的尸检病例中进行了临床病理相关性分析.
- 在LLMD和HC组之间比较PET阳性率.
主要成果:
- 与HC相比,LLMD参与者对tau PET和Aβ PET呈阳性的可能性更高.
- 尸体解剖数据证实了PET的发现,揭示了晚年躁狂或抑郁症患者中各种陶病的更大流行率.

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...

Long-term Depression
2.5K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
