Chronic Pain

January 31, 2008

Chronic Pain in Elderly Patients

In the November 2007 issue of the International Journal of Geriatric Psychiatry, an article presents the result of a study examining chronic pain in depressed geriatric inpatients.  By examining the medical charts of patients who were admitted to a geriatric psychiatric unit over a two year period, 148 patients with a depressive disorder were identified. Of these depressed patients, 62% of patients were found to reports problems with chronic pain. Further analysis found that depressed older adults with chronic pain were more likely to report suicidal ideation, be diagnosed with personality disorder, have chronic care needs, and experience less total sleep time compared to depressed older adults without chronic pain. The results match those of previous studies identifying chronic pain as a possible suicide risk factor in the elderly, particularly when depression is involved.  : Chronic pain-common in depressed older adults-may influence clinical features of depression and should be assessed as a possible suicide risk factor. Prospective studies should examine causal relationships and determine the effects of adequate pain treatment on depression course and suicide risk in older adults.

Chronic Pain Affects Short-term Memory and Attention

In the May 2007 issue of Anesthesia and Analgesia, a study examining the relationship between chronic pain and performance on neuropsychological measures of short-term memory and attention is presented.  A team of researchers at the University of Alberta administered a series of computerized measures of working (short-term) memory and attention to a sample of chronic pain patients.  Their results indicated that two-thirds of the chronic pain patients tested were found to be impaired on tests of working memory and attention.  Additional factors such as age, education level, disturbed sleep, and pain relief were ruled out as possible confounding factors.  Performance on the cognitive tests was not improved by short-term pain relief using analgesics.   The researchers conclude that chronic pain can directly affect cognitive performance which can, in turn, affect quality of life and level of functioning.
