What the animal and cell studies actually show

Dihexa's reputation rests entirely on preclinical work: cultured neurons, memory-impaired rats, and one Alzheimer's mouse model. Some of it is clean and some of it is flagged, and telling them apart is the skill this unit builds.

We walk the key studies, weigh their quality, and confront an uncomfortable feature of the dihexa literature: it comes from very few laboratories, with little independent replication.
