概括
深度学习通过分析关节特征,准确地检测帕金森病 (PD) 中的早期语言衰弱,在药物治疗患者中优于喉测量 (如HNR).
科学领域:
- 语音科学 语言科学
- 计算语言学 计算语言学
- 神经学 神经学
背景情况:
- 帕金森病 (PD) 导致低动力性脱节性关节,影响语音的产生.
- 在PD演讲中,关节和音声子系统的联合分析是有限的.
- 可解释深度学习为语音分析提供了新的措施.
研究的目的:
- 通过使用深度学习,共同分析PD的发音和语音语音子系统.
- 确定语音生物标志物,用于早期检测和监测PD的进展.
- 为了比较深度学习衍生的关节特征与喉特征的灵敏度.
主要方法:
- 分析了50名哥伦比亚西班牙语说者与PD和50名对照者的语音数据.
- 结合深度学习衍生的声学特征后部 (关节) 与声与噪声比率 (HNR) (喉).
- 使用线性混合效应模型来评估与疾病严重程度,年龄和性别的关系.
主要成果:
- PD参与者表现出明显更高的[持续的]后部,表明关节衰弱,特别是在牙科停留.
- [发声]后部在各组之间没有差异,显示口腔收缩减少.
- HNR受母音高度和性别的影响,但并没有将PD与对照区分开来,这可能是由于药物的作用.
结论:
- 深度学习衍生出的发音特征有效地捕捉了PD中微妙的,早期的语音衰弱,特别是在冠状元音中.
- 在服用药物治疗的PD患者中,像HNR这样的喉测量是不那么敏感的.
- 这种方法为开发PD进展的特征级生物标志物提供了一个透明的框架.

Parkinson's Disease: Overview
1.7K
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...

Parkinson's Disease: Treatment

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.

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.
