In recent years, researchers have focused on developing precise models for the progression of Alzheimer's disease (AD) using deep neural networks. Forecasting the progression of AD through the analysis of time series data represents a promising approach.
The primary objective of this research is to formulate an effective methodology for forecasting the progression of AD through the integration of multi-task learning techniques and the analysis of pertinent medical data.
This study primarily utilized volumetric measurements obtained through magnetic resonance imaging (MRI), trajectories of cognitive assessments, and clinical status indicators. The research encompassed 150 patients diagnosed with AD who underwent examination between 2020 and 2022 in Beijing, China. A multi-task learning approach was employed to train forecasting models using MRI data, trajectories of cognitive assessments, and clinical status. Correlation analysis was conducted at various time points.
At the baseline, a robust correlation was observed among the forecasting tasks: 0.75 for volumetric MRI measurements, 0.62 for trajectories of cognitive assessment, and 0.48 for clinical status. The implementation of a multi-task learning framework enhanced performance by 12.7% for imputing missing values and 14.8% for prediction accuracy.
The findings of our study, indicate that multi-task learning can effectively predict the progression of AD. However, it is important to note that the study's generalizability may be limited due to the restricted dataset and the specific population under examination. These conclusions represent a significant stride toward more precise diagnosis and treatment of this neurological disorder.
近年来,研究人员专注于使用深度神经网络为阿尔茨海默病(AD)的进展开发精确模型。通过分析时间序列数据预测 AD 的进展是一种很有前途的方法。
本研究的主要目的是通过整合多任务学习技术和分析相关医学数据,为 AD 的进展预测制定一种有效的方法。
本研究主要利用磁共振成像(MRI)获得的容积测量、认知评估轨迹和临床状态指标。研究包括 2020 年至 2022 年在中国北京检查的 150 名 AD 患者。使用 MRI 数据、认知评估轨迹和临床状态对多任务学习方法进行训练,以进行预测模型训练。在不同时间点进行相关性分析。
在基线时,预测任务之间存在很强的相关性:容积 MRI 测量为 0.75,认知评估轨迹为 0.62,临床状态为 0.48。实施多任务学习框架可将缺失值的插补性能提高 12.7%,预测准确性提高 14.8%。
本研究的结果表明,多任务学习可以有效地预测 AD 的进展。但是,需要注意的是,由于数据集有限且研究对象特定,研究的推广性可能受到限制。这些结论代表着在更精确地诊断和治疗这种神经退行性疾病方面迈出了重要一步。
