Symptoms of depression in older adults with multiple sclerosis (MS): Comparison with a matched sample of younger adults

The study considered for the first time depression in older adults with multiple sclerosis (MS). Depression symptom scores of 27 persons aged over 65 years who were part of a large study of persons with MS (n = 529), were compared with those of a matched sample of younger adults from the same study. The association between cognitive (attitudinal) variables known to explain significant variance in depressive symptoms in younger adults with MS was then considered in the older adult sample. Consistent with findings from studies with general community samples, older adults with MS reported significantly fewer depressive symptoms than younger adults with MS. The relationship between cognitive variables and depressive symptoms found previously in younger adults was also evident for the older adults. Multiple sclerosis related helplessness was found to be significantly higher in older as opposed to younger adults with MS, the opposite of what was predicted given the differences between the groups in depression scores. Differences in the cognitive variables do not appear to explain the differences between older and younger adults with MS in terms of depressive symptoms. This finding offers support for the view that a decrease in emotional responsiveness may explain differences in depressive symptoms between younger and older adults with MS, rather than this being the result of differences in emotional control exerted via cognitive means.
