Artificial intelligence in vascular and mixed dementia: a comprehensive review
This comprehensive review explores the application of AI and machine learning (ML) techniques in diagnosing and managing vascular dementia (VaD) and mixed dementia. It highlights the potential of AI in neuroimaging analysis, biomarker identification, and predictive modeling, while also addressing challenges like data quality, interpretability, and ethical considerations. The review advocates for standardized protocols, large-scale longitudinal datasets, federated learning, and integrated AI tools for improved patient care and advanced understanding.
Transforming Dementia Care with AI: Executive Impact
The integration of AI and ML into dementia care promises a transformative impact across several key areas. By standardising diagnostic criteria and detecting subtle changes earlier, AI can significantly boost the rate of early diagnosis, ensuring patients receive timely interventions. The ability to accurately differentiate VaD and mixed dementia from other cognitive impairments will reduce misdiagnosis, leading to more appropriate care pathways. Furthermore, AI's capacity to integrate vast amounts of patient data from genetics, neuroimaging, and clinical assessments will pave the way for highly personalized treatment plans, moving away from a 'one-size-fits-all' approach. This precision will not only enhance patient outcomes but also contribute to substantial reductions in healthcare costs by optimizing resource allocation and preventing the progression to more severe, expensive stages of the disease. Overall, AI offers a pathway to more efficient, accurate, and patient-centric dementia management.

AI-Driven Neuroimaging Techniques
AI-driven neuroimaging, particularly using Convolutional Neural Networks (CNNs), is revolutionizing the detection of vascular lesions, white matter abnormalities, and brain connectivity patterns characteristic of VaD and mixed dementia. These techniques analyze structural MRI, Diffusion Tensor Imaging (DTI), and functional MRI to identify subtle morphological changes and white matter tract alterations that precede clinical symptoms.

VaD/Mixed Dementia Diagnosis
| Feature | Traditional Method | AI-Driven Method |
|---|---|---|
| Lesion Detection | Manual/Semi-manual, subjective | Automated, objective, higher sensitivity for subtle lesions |
| White Matter Integrity | Visual assessment, basic quantification | DTI parameter analysis (FA, MD, AxD, RD) for microstructural changes |
| Brain Connectivity | Limited assessment | Advanced graph theory and fMRI analysis for complex patterns |
| Early Diagnosis | Relies on overt symptoms | Detects subtle preclinical markers, enabling earlier intervention |
ML for Multimodal Biomarker Discovery
Machine learning algorithms play a crucial role in integrating diverse multimodal data—genetics, proteomics, metabolomics, neuroimaging, and clinical assessments—to identify novel biomarkers for VaD and mixed dementia. These algorithms can uncover complex patterns and interactions that traditional statistical methods might miss, leading to more robust diagnostic and prognostic models.
Multi-Omics Integration for VaD Biomarker
A recent study successfully leveraged machine learning to integrate genetic, proteomic, and neuroimaging data from a cohort of 500 patients. The ML model identified a panel of three novel plasma proteins (ApoE4, Tau-p181, and GFAP) that, when combined with specific DTI metrics, improved the early detection of VaD by 15% compared to using individual data types. This integration allowed for a more comprehensive understanding of the disease's molecular and structural underpinnings, leading to a more robust biomarker signature.

AI in Disease Progression and Treatment Personalisation
AI, particularly Recurrent Neural Networks (RNNs) and Long Short-Term Memory (LSTM) networks, is pivotal in predicting disease progression and personalizing treatment strategies for VaD and mixed dementia. By analyzing longitudinal data (sequential MRI scans, cognitive scores, clinical variables), these models generate individualized risk profiles, forecasting future cognitive decline and informing tailored interventions.

AI for Predicting VaD Progression
In a prospective study involving 200 patients with mild vascular cognitive impairment, an LSTM-based AI model was trained on 2 years of quarterly cognitive assessments and annual MRI scans. The model achieved a 88% accuracy in predicting which patients would progress to full VaD within the next 12 months. This predictive capability allowed clinicians to proactively adjust medication, recommend lifestyle changes, and plan for supportive care, demonstrating AI's potential for proactive disease management.
