Dementia is a neurodegenerative disease that causes a progressive deterioration of thinking, memory, and the ability to perform daily tasks. Other common symptoms include emotional disorders, language disorders, and reduced mobility; however, self-consciousness is unaffected. Dementia is irreversible, and medicine can only slow but not stop the degeneration. However, if dementia could be predicted, its onset may be preventable. Thus, this study proposes a revolutionary transfer-learning machine-learning model to predict dementia from magnetic resonance imaging data. In training, k-fold cross-validation and various parameter optimization algorithms were used to increase prediction accuracy. Synthetic minority oversampling was used for data augmentation. The final model achieved an accuracy of 90.7%, superior to that of competing methods on the same data set. This study's model facilitates the early diagnosis of dementia, which is key to arresting neurological deterioration from the disease, and is useful for underserved regions where many do not have access to a human physician. In the future, the proposed system can be used to plan rehabilitation therapy programs for patients.
痴呆症是一种神经退行性疾病,会导致思维、记忆和执行日常任务的能力逐渐恶化。其他常见症状包括情绪障碍、语言障碍和行动能力下降;但自我意识不受影响。痴呆症是不可逆转的,药物只能减缓但不能阻止退化。然而,如果能够预测痴呆症,它的发作也许是可以预防的。因此,本研究提出了一种革命性的迁移学习机器学习模型,以便从磁共振成像数据中预测痴呆症。在训练过程中,采用 k 折交叉验证和各种参数优化算法来提高预测准确性。使用合成少数过采样技术进行数据扩充。最终模型的准确率达到 90.7%,优于同一数据集上的竞争方法。本研究的模型有助于早期诊断痴呆症,这是阻止疾病引起的神经恶化的关键,对于那些许多人无法获得人类医生服务的服务欠缺地区非常有用。在未来,该系统可以用于为患者规划康复治疗方案。
