Professionals who care for people with intellectual disabilities face many challenges in their work. Ageing in their patients adds further complexity as it exacerbates existing health issues and disabilities. The professionals aim to balance promoting autonomy while also providing care and protection. They approach each unique situation with uncertainty and adapt their approach through discussion and trial. Unlike previous claims, the professionals are not paralyzed by ageing but rather view it as just one of many factors to consider through their established practices of "uncertain decision making". While ageing brings gradual changes, the professionals accept evolving their practices as long as adequate support and resources are provided.
