The study presented today at APSS is the first to establish that insomnia prolongs bouts of sadness, hopelessness and loss of interest in life activities that characterize major depression, making patients less likely to recover. Specifically, the study found that depressed patients with insomnia were nearly 11 times more likely to still be depressed at six months than those sleeping well, and 17 times more likely to remain ill after a year. Data were drawn from Project IMPACT, a study in late-life depression that enrolled 1,801 men and women aged 65 years or older.
"The new findings are especially significant because they suggest that targeted treatment for insomnia will increase the likelihood and speed of recovery from depression," said Michael Perlis, Ph.D., director of the University of Rochester Sleep and Neurophysiology Research Laboratory (URSNRL), and an author the studies presented at APSS and published in the journal. Wilfred Pigeon, Ph.D., asst. director of the sleep lab, was lead author of the study presented today.
