Antidepressant therapy may vary among the elderly with late-life depression, as it becomes more difficult to treat the older the individual is. The study, published in JAMA Psychiatry, examined longitudinal patterns of changes in depressive symptoms in those who were prescribed antidepressant therapy.
Lead author of the study Stephen F. Smagula said, “Elderly patients with late-life depression should get treated, that is the main take-home message from this study. You should get treated, and you should stay with it. Some of these patients take 12 weeks or more to fully respond. Late-life depression is often difficult to treat, and solo venlafaxine is just not going to cut it for a lot of the patients out there. But get treated, stay with it, and also explore adjunctive care or alternatives, as indicated.”
The study reports that nearly 50 percent of seniors with late-life depression have difficulties responding to initial antidepressant therapy.
For the research, which took place between August 2009 and August 2014, participants received antidepressant therapy, which was upped to 300 mg/day over the course of 12 weeks. They found that late-life depression was difficult to treat, and there were different responses to the antidepressant therapy.
Almost half of the participants showed responses to the treatment, but there were three subgroups who did not respond to treatment. Two of the subgroups had high baseline depression levels and the other had moderate baseline depression levels. Dr. Smagula added, “This finding suggests that despite older age and depressive illness, relative preservation of retention ability, which is associated with hippocampal function, may facilitate a rapid response. This hypothesis is consistent with prior evidence linking hippocampal volume to late-life depression treatment outcomes.”
Researchers commented that late-life depression is difficult to treat because depression among the elderly is not well studied. Commenter of the study Dr. Robert Roca added, “It is clear that depression severity by itself does not reliably predict antidepressant response among older adults. Much work remains to be done. We may ultimately be disappointed in our quest to discover robust clinical predictors of response and in the end may need to look to biomarkers for guidance.”
With the rise of illness, disability, and other life changes through the aging process, late-life depression affects many seniors. Chronic depression in the elderly can have both mental and physical consequences, which can, in turn, worsen underlying medical conditions.
It is reported that late-life depression affects nearly six million seniors over the age of 65, yet only 10 percent ever receive treatment for it. The problem surrounding late-life depression in the elderly is that symptoms are often confused with other diseases and ailments, so misdiagnosis is common.
Depression in the elderly differs from depression in younger adults because it increases their risk of heart failure, cardiac disease, and death from other illnesses. Suicide rates are also higher among white males with late-life depression, nearly double when compared to that of the general population.
For successful early diagnosis of late-life depression, it’s important to recognize the symptoms in elderly people and not confuse them with other ailments. Symptoms of depression in the elderly include:
There are many causes and risk factors which put the elderly at higher risk for late-life depression. With all the changes resulting from aging, causes and risk factors of depression in the elderly include:
Late-life depression doesn’t have to affect you simply because you are getting older. Preventative measures can be taken in order to avoid or lower a person’s risk of developing late-life depression. Prevention and self-help tips for depression in the elderly involve:
Creating a social support group – volunteering at churches or in the community, calling up loved ones, visiting friends and family
The older you become the greater your risk is to develop late-life depression, but with simple preventative techniques you can continue enjoying a happy, fulfilled life.
