Abstract :
As the global population ages, the prevalence of cognitive decline and dementia, including Alzheimer's disease, continues to rise,
impacting millions of individuals and placing a significant burden on healthcare systems. Early prediction and accurate monitoring
of dementia progression are critical for timely intervention, personalized care, and slowing disease advancement. However,
traditional diagnostic approaches face challenges, such as reliance on late-stage biomarkers, limited sensitivity of cognitive
assessments, and inconsistencies in neuroimaging. This review explores how artificial intelligence (AI) and machine learning (ML)
are transforming the field of dementia prediction, offering a paradigm shift toward earlier and more accurate assessments.
This paper systematically examines recent advancements in AI and ML applications in predicting cognitive decline and
tracking dementia progression. Key technologies discussed include deep learning for neuroimaging analysis, natural language
processing (NLP) for speech and language pattern identification, and time-series analysis for continuous monitoring through
wearable devices. The role of multimodal data integration, encompassing genetic, behavioral, clinical, and imaging data, is
highlighted as a critical advancement that AI can facilitate, allowing for a comprehensive and personalized approach to risk
prediction.
Despite AI's potential, significant challenges remain, including data quality and diversity, ethical concerns in predictive
diagnostics, and the "black-box" nature of many AI models that make clinical interpretability difficult. The review also discusses
the regulatory and ethical landscape, underscoring the need for transparent, unbiased, and privacy-conscious AI applications in
healthcare. Future directions are proposed, such as advancements in explainable AI (XAI), integration of precision medicine
approaches, and the role of AI in supporting drug development and clinical trials.
In conclusion, while AI and ML offer promising tools for enhancing dementia prediction and management, a collaborative
approach involving researchers, clinicians, policymakers, and patients is essential to harness AI's potential responsibly and
equitably. This paper calls for continued research, interdisciplinary partnerships, and regulatory guidance to ensure AI's ethical and
effective integration into dementia care and management.
