Mental health of older people with mild and moderate intellectual disability in Australia.

The cross-sectional nature of the study limits causal inference. The cumulative effect of chronic health conditions and adverse life events cannot be prevented retrospectively. However, greater awareness amongst both health professionals and care staff that older adults with ID have a high likelihood of significant and/or repeated traumas and need better health care to limit physical co-morbidity may assist in providing support that is better tailored to individual needs in older age to reduce the burden of mental ill-health.
