It is the first study of its kind in Europe, and the only study that can directly compare the ageing of people with intellectual disability with that of the general ageing population. It includes a cognitive assessment using four measures: reported diagnosis of memory disorder; self-rated memory, orientation in time, and Test for Severe Impairment.
The reports of the first, second and third waves of data are available at the IDS-TILDA website and can be accessed here.
