Incidental Findings Identified on Head MRI for Investigation of Cognitive Impairment: A Retrospective Review.

Introduction: Incidental findings are common in presumed healthy volunteers but are infrequently studied in patients in a clinical context.

Objective: To determine the prevalence, nature, and management implications of incidental findings on head MRI in patients presenting with cognitive symptoms, and to quantify and describe unexpected MRI abnormalities that are of uncertain relevance to the patient's cognitive symptoms.

Methods: A single-centre retrospective review of patients attending a regional early-onset cognitive disorders clinic between March 2012 and October 2018.
