Artificial intelligence (AI) is reshaping the healthcare landscape, particularly in diagnostics and disease detection. Recent breakthroughs, such as the use of AI-supported mammography to increase cancer detection rates, highlight the immense potential of AI in improving healthcare outcomes.
A research initiative called AI-Mind is at the forefront of leveraging AI in healthcare. Led by Ira Haraldsen at Oslo University Hospital, AI-Mind focuses on utilizing AI to identify individuals at high risk of developing dementia. The goal is to predict the likelihood of dementia years before it is conventionally diagnosed.
Shifting the Diagnosis Window
Traditionally, dementia is diagnosed after significant symptoms manifest, limiting the effectiveness of interventions. AI-Mind aims to shift the diagnosis window to an earlier stage when interventions can have a more significant impact. By developing an AI-based screening tool, the initiative envisions population-wide screening, including individuals as young as 55. High-risk individuals would then receive proactive follow-ups and interventions.
Unveiling Hidden Risks
The AI-Mind study involves 1,000 participants aged between 60 and 80 with mild cognitive impairment. Among individuals with mild cognitive impairment, there is no way to predict which ones will develop dementia. AI-Mind aims to bridge this gap by effectively categorizing individuals and providing timely interventions for those on the dementia trajectory.
AI-Mind’s Multi-Faceted Approach
AI-Mind utilizes a multi-pronged approach that includes electroencephalography (EEG) to measure brain activity, blood samples, and cognitive assessments. Researchers monitor participants’ cognitive trajectories over two years. Two AI algorithms are being trained concurrently, one analyzing brain communication patterns using EEG data. These patterns change as dementia progresses, similar to the passing dynamics of a football team.
Algorithmic Innovations in Progress
The AI algorithms employed by AI-Mind combine classical machine learning and deep learning. While classical machine learning identifies known dementia indicators, deep learning explores novel patterns independently. Researchers are currently validating whether AI’s predictions align with human assessments.
Predicting Dementia Progression
Through the analysis of EEG data, blood tests, and cognitive assessments, the AI-driven system will identify individuals at high risk of developing dementia. Blood test changes often precede dementia diagnoses by years, offering a promising avenue for early detection. AI-Mind aims to unveil early-stage dementia two to three years before conventional diagnosis by 2026.
Benefits of Early Diagnosis
While there is currently no cure for dementia, early intervention is crucial for effective treatment, especially for Alzheimer’s disease. Disease-modifying medications that can slow down its progression are gaining traction. However, ethical considerations arise when it comes to early diagnoses and limited treatment options.
Promising Developments and Ongoing Research
In the field of dementia research and early diagnosis, significant progress is being made. New medications targeting amyloid plaques in Alzheimer’s patients are being evaluated, both in the USA and Europe. Blood marker analysis is also advancing, streamlining early detection methods.
AI-Mind’s endeavors exemplify the transformative power of AI in healthcare. By harnessing AI’s analytical capabilities, researchers aim to revolutionize dementia diagnostics, enabling early interventions and ultimately improving patient outcomes. While challenges and ethical considerations remain, the collaboration between artificial intelligence and healthcare offers a promising future in disease detection and management.
