Abstract: A dosage of an active ingredient in a treatment that is being provided to or that is being considered for provision to a subject is identified. A level of local amyloid beta is predicted based on the dosage of the active ingredient. A severity of amyloid-related imaging abnormalities (ARIA) manifested as hyperintensities on T2-weighted fluid attenuated inversion recovery (FLAIR) images (ARIA-E) is predicted based on the predicted removal of local amyloid beta, where predicting severity of ARIA-E includes predicting an extent of vascular wall disturbance. A result corresponding to the predicted ARIA-E severity is output.
