概括
患有纤维肌痛 (FM) 的个人表现出嗅觉功能的下降,这可以通过较低的嗅觉测试得分和减少嗅觉通道的微分异性质 (FA) 来证明. 这些发现表明,在FM患者的神经系统中存在潜在的髓和轴突变化.
科学领域:
- 神经科学是一个神经科学.
- 嗅觉研究 嗅觉研究
- 医疗成像医学成像
背景情况:
- 纤维肌痛 (FM) 影响全球数以百万计的人,有争议的病因发生.
- 新出现的证据将FM与中枢和外周神经系统功能的改变联系起来,包括嗅觉通路.
- 了解FM的嗅觉系统变化对于揭开疾病机制至关重要.
研究的目的:
- 临床评估纤维肌痛患者的嗅觉功能.
- 通过神经成像来研究神经系统嗅觉通路的结构变化.
- 为了将嗅觉功能与纤维肌痛神经成像发现相关联.
主要方法:
- 横截面研究比较了30名FM患者和31名对照组.
- 嗅觉功能通过康涅狄格州化学感官临床研究中心 (CCCRC) 和butanol值测试 (BET) 进行评估.
- 扩散张力成像 (DTI) 用于嗅觉通道和内耳皮层体积计算的管道学.
主要成果:
- 纤维肌痛患者在BET和CCCRC气味识别测试中得分明显较低.
- 嗅觉通道的平均分数异构 (FA) 值在FM组中双边降低.
- 在任何一组中,嗅道FA值和嗅觉测试得分之间没有发现显著的相关性.
结论:
- 这项研究支持了纤维肌痛患者经历嗅觉功能受损的假设.
- 在FM患者的嗅觉通道中减少的FA可能表明髓结构或轴突完整性受损.
- 嗅觉系统的改变代表了纤维肌痛的潜在神经生物学标志物.

44.0K
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.

Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.
