Elderly depression: The age factor in depression 2/2

Depression does not become more common as you get older, but it may become more complex.  Recent findings on age and depression confirm the so-called ‘U-curve’ of well being and happiness over the human life cycle.  Put simply, we’re at our most dissatisfied in our mid-forties – a finding that’s so in 47 of 55 countries surveyed. Depression seems to have much less of an impact in terms of daily disability in the older age groups.

But depression in the elderly is complicated by other diseases and it’s often hard to sort out cause and effect. Do you get depressed because you’ve had a heart attack? Does depression make it more likely that you’ll get diabetes? We really don’t know! Elderly depression is not so much about the numbers of people who are depressed, but more a matter of knowing how best to treat it.  Higher costs in terms of time, money and health care resources are involved in treating elderly depression and, too often, such resources simply aren’t adequate.  Moreover, the growing number of people over 60 (and, proportionately, even more so those over 80), means that elderly depression is set to rise dramatically. As yet, society seems unprepared for this.   Recent findings from the Zürich Study of younger persons (stretching over 20 years and with an age range of 20-41) have pointed to high levels of chronic depression existing alongside heart and lung problems, insomnia, pain (other than backache and headache) and sexual problems. Interestingly, the authors ascribe the heart and lung problems   in this age group as probably ‘associated with increased anxiety’.

In the elderly, by contrast, depression tends to exist alongside age-related conditions like stroke, high blood pressure, atrial fibrillation, diabetes, cancer and dementia.

The Zürich Study also found that other mental health problems co-exist with depression in the   20-41 age group. The six leading risk factors were found to be tobacco dependence, substance abuse, generalized anxiety disorder, obsessive-compulsive syndrome, panic attacks and alcohol use disorder. Again, with the exception of anxiety, these are probably more prominent risk factors for depression in younger persons than for the elderly. The psychosocial impact of bereavement, loneliness and growing physical and cognitive problems in coping with the normal activities of daily life are more characteristic associations with depression in old age.

The next article in this series looks at current   practice in the diagnosis and treatment of elderly depression.

Depression in the elderly – how to understand it

Depression is perhaps the most frequent cause of emotional suffering in later life’ said Dan G Blazer, Professor of Psychiatry at DukeUniversity.  Being socially isolated, particularly after the death of a partner, and co-existing illness may contribute towards depression in older people.  Depression often goes undiagnosed or untreated so it becomes an increasing public health issue in our ageing society.  The challenge, then, is more one of managing depression effectively in later life rather than understanding the condition.

How widespread is depression among older people? Recent surveys suggest a prevalence between 1.8% in the over 55s to 15% in those over 85.  While depression is actually less prevalent among the old, compared to the young,  major depression may be more common.  There is also a clear link between chronic disease and depression, with those in nursing homes showing higher rates than those living in the community. But is the link a causal one? We know that illness can cause depression (and vice versa), but we cannot be sure residents of nursing homes are depressed because they are ill or because their care is not sufficiently ‘caring’.

And when it comes to the gender gap, it’s well known that women are more prone to depression in Europe and North America.  But a new study from China, covering 2,633 adults, showed that the gender difference is insignificant, save in the 35-49 age group where lifetime prevalence for major depression for men was 3.6% compared to 2.3% for women.

There is also a cultural dimension to elderly depression. A meta-analysis of nine European centres revealed a prevalence of 8.8% in Iceland in the 88-89 age group compared to 23.6% in Munich in the over 85s.  And, among the ‘oldest old’ 2% declared ‘life not worth living’ and 3% ‘wish to be dead’ in Iceland, compared to 16% and 25% in Berlin and 30% and 29% in Munich. The researchers wondered if some lingering distress from the Second World War could account for high rates of depression among very elderly Germans.

Finally, a number of risk factors for elderly depression have been identified, including medical burden, bereavement, chronic insomnia, cerebrovascular disease, Alzheimer’s disease and Parkinson’s disease.  In the next article in this series, we will explore differences between depression in elderly and young persons.
