ARIA Monitoring & Documentation

ARIA (amyloid-related imaging abnormalities) documentation

For any ARIA evidence, specify radiographic severity and symptom presence.

ARIA documentation

ARIA-E severity and symptoms: ARIA-E options: mild asymptomatic or mild with mild/moderate/severe symptoms; moderate with any symptoms; severe with any symptoms.
