概括
化陶 (p-tau) 积累与阿尔茨海默病 (AD) 患者的抑郁和冷漠率较低有关. 像APOE ε4这样的遗传因素可能会影响这种关系,这表明p-tau在情绪症状预测中的潜在作用.
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:
- 阿尔茨海默氏病 (AD) 和轻度认知障碍与认知衰退和神经精神症状 (NPS) 相伴,包括情绪障碍.
- 关于AD生物标志物对NPS情绪症状的预测价值仍在争论中.
- 这项研究调查了酸化 (p-tau) 与NPS中的抑郁,焦虑和冷漠之间的联系.
研究的目的:
- 分析具有认知障碍的患者中酸化 (p-tau) 水平和特定情绪症状 (抑郁,焦虑,冷漠) 之间的关系.
- 探索阿波利波蛋白E (APOE) ε4基因型对p-tau和情绪症状之间的关联的影响.
主要方法:
- 对122名被诊断患有正常认知,轻度认知障碍或AD的老年患者进行了横截面调查.
- 神经精神病学清单问卷 (NPI) 评估了NPS,脑脊液 (CSF) 的p-tau水平通过腰部穿刺进行测量.
- 反向概率权重方法调整为p-tau正和负组之间的人口差异.
主要成果:
- 在p-tau积累和抑郁和冷漠的发病率降低之间发现了显著的关联.
- 不携带APOEE ε4的患者表现出p-tau与抑郁之间的负相关性趋势.
- 在APOE ε4载体中没有观察到这种趋势,这表明p-tau-mood关系的潜在遗传调制.
结论:
- 有证据表明,在NPS中p-tau和抑郁/冷漠之间存在负相关性,这可能是由APOE ε4状态调节的.
- 需要进一步的纵向研究来验证p-tau在预测认知衰退中的情绪症状进展方面的实用性.
- 这些发现有助于理解AD病理学,遗传学和神经精神病症症状之间的复杂相互作用.

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Long-term Depression
2.6K
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.

Alzheimer's Disease: Overview
506
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...
