AI Technical Summary

Technical Problem

Current Parkinson's pathological subtype classification techniques lack objective quantitative indicators, making it impossible to achieve accurate classification in the prodromal stage of the disease. They are easily influenced by physician experience and cannot distinguish the pathological origin differences between body-priority and brain-priority subtypes, thus limiting the accuracy of classification.

Method used

By acquiring magnetic resonance imaging data, extracting the magnetic susceptibility values ​​of key brain regions, constructing a standardized feature matrix, initializing a weighted adjacency matrix, constructing a target optimization function containing a fitting function, a sparse regularization term, and a loop-free constraint penalty term, iteratively optimizing the causal graph, forming a specific causal graph, evaluating the causal effect, and realizing the subtyping of Parkinson's pathological types.

Benefits of technology

This study achieved objective and quantitative classification of Parkinson's disease pathological subtypes, revealed the pathological transmission mechanism, improved the accuracy and reliability of classification, and provided a scientific basis for early intervention and personalized diagnosis and treatment.
