Association of hearing, vision, and dual sensory impairment and risk of Alzheimer's disease: a nested case-control study.

ABSTRACT:

Background

Hearing impairment is a known risk factor for Alzheimer's disease (AD), although less is known about vision impairment or dual sensory impairment (DSI) as risk factors for AD. We studied the association between diagnosed hearing impairment, visual impairment, or DSI, and the risk of AD.

Method

The Medication use and Alzheimer's disease study (MEDALZ) is a register-based nested case-control study including 70,718 community-dwelling persons diagnosed with incident AD in 2005-2011 in Finland and their 282,845 matched controls.
