Co-pathology may impact outcomes of amyloid-targeting treatments: clinicopathological results from two patients treated with aducanumab.

Aducanumab is one example of a class of amyloid-targeting antibodies proposed as treatment for early AD [[4], [9]], but few clinicopathological studies are available from patients given these treatments.

The extensive tau neurofibrillary pathology suggests that either insufficient amyloid-lowering was achieved initially (remaining > 25 CL) or that tau spreading and propagation continue after amyloid-lowering unless maintenance dosing is administered.
