概括
嗅觉下降,包括嗅觉识别,歧视和嗅觉值受损,与老年人的身体虚弱密切相关. 这表明嗅觉测试可能是一个简单的选工具,用于脆弱性.
科学领域:
- 老年学是一门学科.
- 神经科学是一个神经科学.
- 临床医学 临床医学
背景情况:
- 全球老龄化人口面临着越来越多的脆弱率.
- 嗅觉衰退是已知的脆弱性和死亡率的预测因素.
- 脆弱性和嗅觉子域 (识别,歧视,值) 之间的具体联系尚未得到充分理解.
研究的目的:
- 调查嗅觉子域与身体脆弱现象型 (PFP) 之间的关联.
- 探索嗅觉评估作为脆弱查方法的潜力.
主要方法:
- 一项病例控制研究涉及45名脆弱和45名非脆弱个体,年龄和性别相匹配.
- 嗅觉功能使用嗅探棒进行评估,测量嗅觉值 (OT),歧视 (OD),识别 (OI) 和复合TDI得分.
- 身体虚弱表型 (PFP) 通过至少三个标准的存在来确定:身体不活动,疲劳,肌肉虚弱,慢步,和无意减肥.
主要成果:
- 该研究包括90名参与者 (平均年龄为83.1岁,60%为女性).
- 与非脆弱个体相比,脆弱个体在所有嗅觉测量 (OI,OD,OT和TDI) 中的得分明显较低 (所有人p < 0.001).
- 任何嗅觉评分下降一点与明显增加的脆弱率有关 (ORs从1.54到2.29不等).
结论:
- 嗅觉子域得分与身体虚弱之间存在着强烈的关联.
- 嗅觉可以作为脆弱的可访问指标.
- 建议进行进一步的纵向研究,以确认嗅觉对脆弱性的预测价值.

Physiology of Smell and Olfactory Pathway
8.3K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

Factors Affecting Illness
4.2K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Alzheimer's Disease: Overview
461
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...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
