Thanks for your question.
The data we have, sometimes we don't think is necessarily as accurate as we'd like it to be. A lot of the ways mental illness manifests in older adults aren't necessarily captured by some of the tools that we have. If you take depression, for example, some of our data show that in community dwellings samples the rates are similar across all ages, at 12% to 15%. We also think there are probably a lot of older adults who aren't being captured properly in those statistics.
However, if you look within long-term care, the numbers for depression go up significantly, with up to almost half of all residents in long-term care showing some symptoms of depression. Some surveys have shown between 80% to 90%.
I think probably what's most important know is that the numbers don't change as people age. In fact, we see an increase. If we're saying one in five Canadians lives with a mental illness, that would also be true for older adults with certain segments being at higher risk.
