Taking a Systems Approach to Chronic Illness in Old Age.

We are living through a demographic transition from a world in which there were lots of young people and very few older adults to one in which the numbers in these age groups are becoming more evenly balanced. One reason for this is that more of us are living into our seventies, eighties, nineties, and beyond. That is the good news. Unfortunately, the chance of developing chronic illnesses (including diabetes, arthritis, and dementia) is typically higher for people in these older age groups than for those who are younger. Because we do not know how to cure these illnesses, many of us will spend at least some of this extra time with one or more chronic illness. While we are more likely than in the past to live into older age, we are likely to be living with illness when we get there. That raises a challenge: how should we respond to this change?
