概括

血神经纤维光 (NfL) 有效地区分了行为变异前性痴呆症 (bvFTD) 和初级精神疾病 (PPD). 这种血液生物标志物具有很高的准确性,有助于神经退行性疾病的差异诊断.

科学领域:

神经科学是一个神经科学.
生物标志物发现发现
精神病学是一个精神病学.

背景情况:

神经纤维光 (NfL) 是神经退行性疾病的有前途的血液生物标志物.
从临床上讲,将神经退行性疾病与初级精神疾病 (PPD) 区分开来是一项挑战.
行为变异前性痴呆症 (bvFTD) 经常被误诊为PPD.

研究的目的:

调查血NfL在区分bvFTD和PPD中的诊断效用.
评估NfL解释的大型规范数据集和统计模型的性能.
评估主要抑郁症 (MDD),双相情感障碍 (BPAD) 和耐治疗精神分裂症 (TRS) 的血NfL水平.

主要方法:

在患有MDD,BPAD,TRS和bvFTD的患者中测量了血NfL水平.
一个大型参考队列 (对照组2,n=1926) 用于位置,尺度和形状 (GAMLSS) 建模的通用添加模型进行建模.
使用一般线性模型分析了年龄匹配的对照组 (对照组1,n=96).

主要成果:

与所有PPD和对照组 (<11 pg/mL) 相比,bvFTD (34.9 pg/mL) 的血NfL水平显著更高.
在区分bvFTD与PPD方面,NfL表现出高准确度 (88%的特异性,86%的灵敏度).
使用大型参考队列的GAMLSS模型提供了对个别NfL水平的精确解释,优于使用本地控制的模型. 与对照和TRS相比,在BPAD中观察到略高的NfL.

结论:

血NfL是区分bvFTD和PPD的宝贵生物标志物,对于差异诊断至关重要.
这项研究呈现了迄今为止针对NfL分析的最大的BPAD患者队列.
使用大型参考队列和先进建模 (GAMLSS) 对临床转化和神经退行和精神疾病的未来研究有重大影响.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Neural Regulation

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.
