Should We Disclose Amyloid Imaging Results to Cognitively Normal Individuals?

SUMMARY Demonstration of brain accumulation of fibrillar amyloid-β protein via PET with amyloid-specific ligands may support the diagnosis of Alzheimer’s disease (AD). There is increasing recognition of the potential use of amyloid imaging to detect the pathology of AD in vivo in individuals with no ostensible cognitive impairment. Research use of amyloid PET in cognitively normal patients will be key to the pursuit of therapies able to delay cognitive impairment and dementia due to AD. We review the pros and cons of disclosing amyloid imaging results to cognitively normal individuals in clinical and research settings and provide draft recommendations.
