Implication

Machine learning study uncovers key neuroimaging and genetic biomarkers in individuals across Alzheimer's disease stages, highlighting critical pathways and brain regions for early detection.

Key Points

Develop a feature construction method and genetic multi-kernel support vector machine framework combining MRI imaging and genetic data to classify Alzheimer's disease, early mild cognitive impairment, and healthy controls.
Constructed features using eigenvalues of the top 24 single nucleotide polymorphisms across 24 Alzheimer's disease-associated genes alongside voxel-based morphometry from brain MRI scans.
Optimized the weights of a three-kernel support vector machine using a genetic algorithm to detect discriminatory features among Alzheimer's disease, early mild cognitive impairment, and healthy control groups.
Identified significant structural brain regions linked to disease progression, including the right superior frontal gyrus, right inferior temporal gyrus, and right superior temporal gyrus.
Identified key susceptibility genes associated with Alzheimer's disease, including CSMD1, RBFOX1, PTPRD, CDH13, and WWOX.
Discovered significant biological pathways involved in disease pathology, notably the calcium signaling pathway (corrected p = 1.35 × 10⁻⁶) and cell adhesion molecules (corrected p = 5.44 × 10⁻⁴).
