“…The life expectancy of people with intellectual disabilities has increased constantly in recent decades and is steadily approaching the life expectancy of the general population (Bahk et al, 2022; Denninger, 2020; Dieckmann et al, 2015; Ng et al, 2015). This improvement has come about as the result of medical progress, deinstitutionalization, more intense social relationships, greater cognitive stimulation, better access to medical care and changes in nutrition (Dieckmann et al, 2015; Haveman & Stöppler, 2010; Putnam et al, 2021). However, the longer life expectancy of people with intellectual disabilities has also been accompanied by an increase in the incidence of age‐related problems, for example, chronic constipation, urinary incontinence, thyroid disorders, mental and physical illness, (García‐Domínguez et al, 2020; Kuske et al, 2016) and, in particular, a rise in the numbers affected by dementia (Alzheimer's Association, 2022; Grundwald et al, 2017; McCallion et al, 2021).…”
