Guided pathways
Enter the field through the question you care about.
Each pathway combines a chapter, visual model, diagnostic profile, evidence claim, and open research question. Use the full course for depth; use these routes for orientation.
Observation, phenotype, etiology, mechanism, and clinical action.
Vascular amyloid, lobar hemorrhagic markers, nonhemorrhagic injury, clearance, inflammation, and AD overlap.
Pathologic heterogeneity, deep-perforator patterns, candidate MRI phenotypes, and the validation gap.
Different purposes, evidence achievements, reference standards, and failure modes.
Use distribution and context as probability updates—not exclusive labels.
Separate pathology-linked development, repeatability, outcome association, external accuracy, and utility.
Define constructs, lock models, control co-pathology, and test transportability.
Browse gaps with a current answer, missing piece, and potentially decisive design.
