概括

较低的气味检测能力与较高的认知障碍风险有关,特别是在老年女性中. 这种嗅觉测试可能有助于早期检测轻度认知障碍.

科学领域:

神经科学是一个神经科学.
老年学是一门学科.
嗅觉研究嗅觉研究

背景情况:

嗅觉功能下降越来越多地与认知障碍风险有关.
有限的研究使用详细的嗅觉数据探索了年轻成年人的这种联系.
很少有研究研究不同年龄段的气味强度歧视和认知功能.

研究的目的:

调查详细的嗅觉测试数据 (气味强度) 与疑似认知障碍之间的关联.
确定这种关联是否在老年人和年轻人之间有所不同.
评估精细的嗅觉测试对认知健康查的有用性.

主要方法:

1,450名参与者完成了蒙特利尔认知评估 (MoCA-J) 的日语版本.
高分辨率嗅觉测量使用了三个强度级别的六种气味.
对人口统计和生活方式因素进行调整后的物流回归分析.

主要成果:

可辨别的气味强度的下限与更高的MoCA-J分数相关.
薄荷和充的子气味是认知状态的关键区分因素.
这种关联在60-74岁的女性中是显著的 (aOR 0.881,p=0.024).

结论:

有证据支持气味强度歧视与认知功能之间的联系.
有较少气味但多种强度水平的嗅觉测试显示,对早期轻度认知障碍检测有前途.
这种方法似乎特别适用于识别老年女性 (60-74岁) 的认知衰退.

Olfaction

Olfaction

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Olfactory Receptors: Location and Structure

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
