Neuroscience trials struggle to show benefit because symptoms are subjective and variable, and eCOA strengthens dossiers by standardizing ClinRO administration, capturing outcomes in real time to reduce recall bias, and adding patient and caregiver perspectives that clinician scales miss.

Patients don’t experience primary endpoints, so trials that stop at biomarkers and rigid rating scales risk declaring success while leaving daily burden untouched, and digital tools only deliver meaningful evidence when they are co-designed with patients and deployed with restraint.
