Abstract

Objectives

There are more than 66,000 Ontario adults living with intellectual and developmental disabilities (IDD). While the risk of dementia is well established among those with Down Syndrome (DS), there is limited research in persons with IDD excluding DS (Non-DS IDD). This study aimed to compare the incidence and prevalence of dementia in Ontario adults with and without IDD over time and by demographic information.

Methods

Administrative data were used to calculate and compare the annual age- and sex-adjusted cumulative incidence and period prevalence of dementia from fiscal years 2011/12 to 2020/21 in three cohorts: (1) Non-DS IDD, (2) DS, and (3) No IDD.

Results

Compared to persons without IDD, cumulative incidence of dementia was on average 4.27 and 5.33 times higher in persons with Non-DS IDD and DS respectively and period prevalence of dementia was on average 4.87 and 5.93 times higher in persons with Non-DS IDD and DS respectively.

Conclusions

Given the increased rates of dementia within the IDD population, it is imperative that early dementia screening take place, appropriate health and social services are implemented and more actions are taken to delay the onset of dementia, while considering the needs of this population.

安大略省有智力和发育障碍和没有智力和发育障碍的成年人中痴呆症的发病率和流行率

安大略省有超过66,000名成年人患有智力和发育障碍（IDD）。虽然唐氏综合症（DS）患者患痴呆的风险已得到充分确认，但对除DS（非DS型IDD）外的IDD患者的研究有限。本研究旨在通过人口统计信息，比较安大略省患有和不患有IDD的成年人痴呆症的发病率和患病率。方法使用管理数据计算和比较2011/12财政年度至2020/21财政年度三个队列(1)非DS型IDD、(2)DS型IDD和(3)非DS型IDD的年度累积发病率和期间患病率。结果非DS型和DS型痴呆的累积发病率分别是非DS型和DS型痴呆的4.27倍和5.33倍，痴呆的期患病率分别是非DS型和DS型痴呆的4.87倍和5.93倍。鉴于IDD人群中痴呆症发病率的增加，必须进行早期痴呆症筛查，实施适当的卫生和社会服务，并采取更多行动来延迟痴呆症的发生，同时考虑到这一人群的需求。

期刊介绍： The rapidly increasing world population of aged people has led to a growing need to focus attention on the problems of mental disorder in late life. The aim of the Journal is to communicate the results of original research in the causes, treatment and care of all forms of mental disorder which affect the elderly. The Journal is of interest to psychiatrists, psychologists, social scientists, nurses and others engaged in therapeutic professions, together with general neurobiological researchers. The Journal provides an international perspective on the important issue of geriatric psychiatry, and contributions are published from countries throughout the world. Topics covered include epidemiology of mental disorders in old age, clinical aetiological research, post-mortem pathological and neurochemical studies, treatment trials and evaluation of geriatric psychiatry services.
