Abstract Psychosis is a common symptom in neurodegenerative diseases that contributes to significant patient and caregiver burden. While neuroimaging studies have implicated various brain regions in psychosis, findings have been inconsistent across different disease entities and psychosis subtypes. This study aimed to identify structural neuroanatomic changes associated with specific patterns...
Although beta-amyloid (Aβ) deposition is a characteristic feature of Alzheimer's disease (AD), this pathology is commonly found in elderly normal controls (NC). The pattern of Aβ deposition as detected with Pittsburgh compound-B positron emission tomography (PIB-PET) imaging shows substantial spatial overlap with the default mode network (DMN), a group of brain regions that typically...
