One abnormal amyloid group causes other healthy amyloid groups near it to also mutate, eventually they form large groups of amyloid deposits, called plaques or fibrils. Brain imaging: Imaging of the brain's structure to detect enlargement of the ventricles, often with magnetic resonance imaging (MRI) or CT scan, plays a key role in diagnosing normal pressure hydrocephalus.
