Abstract

Objective: To assess the psychological impact of disclosing a positive or negative amyloid brain scan result to symptomatic individuals with mild cognitive impairment (MCI) or mild Alzheimer's disease (AD).
Design: Prospective longitudinal cohort study.
Setting: Florey Institute of Neuroscience \& Mental Health, University of Melbourne, Australia.
Participants: A total of 133 individuals aged 50--85 with MCI or mild AD enrolled in the study with data collected between October 2014 and June 2016.
Interventions: Disclosure of amyloid imaging results to participants.
Measurements: Positron emission tomography (PET) brain amyloid imaging with [18F]-NAV4694; psychometric scales including the Center for Epidemiologic Studies Depression (CES-D) scale, Geriatric Depression Scale (GDS), Hospital Anxiety and Depression Scales (HADS-A and HADS-D) and State-Trait Anxiety Inventory (STAI) performed before and after disclosure of amyloid imaging results.
Results: We did not observe any worsening of psychological health with a panel of psychometric scales assessed on individuals to whom amyloid brain scan results were disclosed.
Conclusions: We consider it safe, without apparent risk of harm to patients, to disclose amyloid imaging results to patients who have no prior history of neuropsychiatric illness.
