Machine learning is a transformative technology that enables systems to autonomously learn and improve from experience without being explicitly programmed. It leverages algorithms to identify patterns, make decisions, and predict outcomes by analysing large datasets. The existing system is predicting the Dementia by analysing sleep disturbances in older adults using machine learning algorithms. The system uses a datasetfromtheSwedishNationalStudyon Aging and Care in Blekinge (SNAC-B), involving older adults aged 60 and above. The dataset includes personal and sleep- related featureswith five machine learning algorithms—gradient boosting, logistic regression, Gaussian naive Bayes, random forest, and support vector machine—are used to analyse the data. The existing system only has the feature of predicting Dementiain olderadultsbyanalysingtheir sleepdisturbancebutlagginginclassifying thediseasecondition, real-time monitoring and care for the affected patients. To overcome these shortcomings, we have proposedtodevelopanandroidapplication that is used for classifying Dementia and monitoring the diagnosed patient and to provide care.
Introduction
Dementia Overview:
Dementia is a progressive neurological disorder causing decline in memory, reasoning, language, and problem-solving, severe enough to disrupt daily life. It mainly affects older adults and includes subtypes such as Alzheimer’s Disease, Vascular Dementia, Lewy Body Dementia, and Frontotemporal Dementia. MRI scans reveal brain abnormalities like hippocampal atrophy and white matter hyperintensities associated with dementia.
Machine Learning in Dementia Diagnosis:
Advanced machine learning (ML) models, especially those using transfer learning and hybrid architectures combining Convolutional Neural Networks (CNN) with ResNet (e.g., ResNet-34 or ResNet-101), have been employed to classify dementia stages from MRI scans with high accuracy. These models automatically extract complex features from neuroimaging data and improve diagnostic precision. Key datasets used include ADNI and OASIS.
Literature Highlights:
Deep learning models like VGG, DenseNet, and InceptionResNet have shown promising accuracy for vascular dementia detection.
ML techniques combining clinical, imaging, and voice data improve dementia prediction.
Gradient-boosted trees and survival analysis methods effectively predict dementia progression.
Support vector machines and CNNs aid early detection of progression from mild cognitive impairment to Alzheimer’s.
Proposed System:
The proposed system integrates CNNs with ResNet-101 to accurately classify dementia into mild, moderate, and non-dementia stages. Preprocessing includes resizing, normalization, noise reduction, and data augmentation for better generalization. The system is supported by a mobile app built with React Native for real-time patient monitoring via GPS tracking, medication reminders, and alerts to caregivers, enhancing patient safety and care adherence.
Implementation Details:
Secure role-based login system for patients and caregivers.
Patient module offers easy navigation for viewing medication schedules, alerts, feedback, and location.
Results:
The model achieved 92.5% accuracy, 91.2% precision, 93.0% recall, and a 92.1% F1 score, indicating strong performance in dementia detection with balanced handling of false positives and negatives.
The system showed reliable, real-time operation of the app modules with smooth user experience and secure access.
Conclusion
The dementia care application has successfully integrated key features aimed at improving the well-being of dementia patients and streamlining the caregiving process. By providing separate modules for patients and caretakers, the app ensures that each user has access to the tools and information most relevant to their role. The patient module offers a user-friendly interface that allows patients to track their medication times, receive reminders, view their profiles, and submit feedback. The caretaker module provides real-time location tracking, medication management, and easy access to the patient’s feedback, ensuring caregivers can provide timely support. The dementia classification model incorporated in the system further contributes to early detection and accurate diagnosis, using machine learning to identify potential dementia cases. The system has shown strong performance in usability, real-time data processing, and accurate predictions, proving its effectiveness in a practical setting. Overall, this project offers a significant advancement in dementia care by combining technology and healthcare to provide more efficient, personalized, and supportive care.
