A recently published study in the journal PLoS-One has found that more than half of older men who use antidepressant medication or psychotherapy are not responding to treatment.
Lead author Professor Osvaldo Almeida, Research Director of the Western Australian Centre for Health and Aging at The University of Western Australia, said the finding was surprising and alarming.
“This is a big issue, not only because depression causes significant personal suffering and disability, but also because our results show that these men are also more likely to die,” Professor Almeida said.
“We found that older men who were using antidepressants but remained depressed had a substantially higher mortality risk. However, men using antidepressants who were free of depressive symptoms had a similar mortality risk over 10 years as the rest of the population.
“The most plausible explanation for these results is that the increased mortality risk associated with antidepressant use is not due to the medication itself, but to the persistence of depressive symptoms despite treatment. In other words, it is the depression that is contributing to shorten people’s lives.”
