The number of people with intellectual disability living into old age continues to increase. As one ages, generally, functional ability decreases and health issues increase, with recognising and responding to the health needs of the person with intellectual disability of great importance and the responsibility of the intellectual disability nurse. The nurse must review and adjust the way they deliver care to ageing people with intellectual disability, not only in terms of responding to their health needs but also through collaborative working within teams and other services. As Ireland has specifically trained nurses in intellectual disability, it has a prime opportunity to address the health needs and concerns of people with intdisability and actively advocate for how services develop and responds to the changing health needs of ageing people with intellectual disability.
