Description
The study reveals completely divergent pathological pathways by sex but doesn’t explain what upstream factors drive males toward lipid/synaptic alterations while females develop robust neuroimmune signatures. This fundamental mechanistic gap underlies the entire sexual dimorphism phenomenon.
