Inverse association for diagnosis of Alzheimer's disease subsequent to both melanoma and non‐melanoma skin cancers in a large, urban, single‐centre, Midwestern US patient population

Background Although literature demonstrates a decreased risk of Alzheimer's disease (AD) in individuals with various cancers, including squamous cell cancers (SCC) and basal cell cancers (BCC) comprising non‐melanoma skin cancers (NMSC), there is a paucity of literature to substantiate an association between malignant melanoma (MM) and AD. Objective The aim of this study was to determine whether an association exists between MM and AD as well as for NMSC and AD. Methods A large urban, Midwestern, US, single‐centre, medical record (EMR) data repository was searched between January 2001 and December 2015, to identify all patients at age ≥60 and
