まとめ
パーキンソン病 (PD) の嗅覚機能障害は,時間の経過とともに認知機能の悪化と関連しています. 早期の嗅覚検査は 将来の認知能力の低下を 予測する可能性があります 特に意味論的流暢性においてです
科学分野:
- 神経科学
- 神経学
- ゲロントロジー
背景:
- 嗅覚機能障害は,パーキンソン病 (PD) の一般的な,早期の進行症状です.
- 嗅覚の低下とPDにおける非運動症状の進行の間の縦断的な関連は完全に理解されていません.
研究 の 目的:
- PD患者の嗅覚機能と (非) 運動症状の間の縦断的な関係を調査する.
- 嗅覚の低下と認知機能の低下との関連を 10年以内に具体的に調べる
主な方法:
- 90人のPD患者は,初期と10年後に評価された.
- 嗅覚機能はペンシルベニア大学の嗅覚識別テスト (UPSIT®) を使用して測定された.
- 全般的認知機能 (MMSE) と特定の認知テスト (意味論的流暢性) を含む非運動症状が評価されました.
主要な成果:
- UPSIT®スコアの低下は,MMSEスコアの低下と意味論の流暢性の悪化と相関しています.

Olfaction
45.1K
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.

Olfactory Receptors: Location and Structure
9.6K
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...

Physiology of Smell and Olfactory Pathway
9.5K
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.

Parkinson's Disease: Overview
702
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

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.

Parkinson's Disease: Treatment
376
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
