Abstract

Purpose

Information on the risk of dementia in aging persons with intellectual and/or developmental disability (IDD) in Manitoba, Canada is lacking. The purpose of this paper is to estimate dementia prevalence in adults with IDD.

Design/methodology/approach

Anonymized population-level health and non-health administrative data (1979-2012) contained in the Population Health Research Data Repository of the Manitoba Centre for Health Policy (MCHP) were linked to identify adults with IDD, and estimate the prevalence of dementia based on the presence of ICD codes. Prevalence of dementia was estimated for persons aged 18-55 years and 55+ years, and was reported by sex, type of residence, region of residence, neighbourhood income quintiles, and IDD diagnostic category.

Findings

Of the 8,655 adults with IDD identified, 8.1 per cent had an indication of dementia in their medical records; an estimate three times greater than that found for those without IDD (2.6 per cent). More than 17 per cent of Manitobans with IDD aged 55+ years had an indication of dementia, which was nearly twice the rate reported previously. Of those with IDD and dementia, 34.7 per cent lived in long-term care facilities.

Originality/value

Health and social support services are typically available to individuals with dementia aged 65+ years; thus, younger adults with IDD and dementia may not be eligible for those supports. To promote equity in health and access to care, dementia screening and increased supports for aging individuals with IDD are recommended.
