设计一项基于医院的研究,研究功能连接和MRI放射学在评估AIS后一年PSCI的预测作用.
探索先进的MRI和定量EEG (QEEG) 在预测中风后认知衰退方面的实用性.
确定PSCI的早期生物标志物,以告知治疗策略.

主要方法:

在AIS之后,招募了144名患者,并在一年内进行了全面评估.
使用神经心理学测试,脑部MRI (包括放射学) 和定量EEG (QEEG).
使用考克斯比例危险模型进行统计分析,以确定预测因素并构建预测模型.

主要成果:

该研究旨在评估AIS后6个月和12个月的PSCI发生情况.
二次结果包括PSCI严重程度,复发性AIS和死亡率.
预测模型将整合QEEG,MRI放射学和临床数据.

结论:

早期发现有PSCI风险的AIS患者对于开发有效的治疗方法至关重要.
改善PSCI的预测可以帮助减少缺血性中风的重大社会和经济负担.
这项研究旨在加强对大脑和认知储备的评估,以改善患者的治疗结果.

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
