Psychiatrists have long thought that depression causes insomnia, but new research suggests that insomnia can actually precede and contribute to causing depression. The causal link works in both directions. Two small studies have shown that a small amount of cognitive behavioral therapy to treat insomnia, when added to a standard antidepressant pill to treat depression, can make a huge difference in curing both insomnia and depression in many patients. . . .I have certainly noticed that depression and irregular sleep habits go together, and more evidence keeps coming in to show that circadian rhythms are fundamental to the function of our minds and bodies. So this is certainly intriguing.
A study of 66 patients by a team at Ryerson University in Toronto found that the cognitive therapy for insomnia, a brief and less intense form of talk therapy than many psychiatric patients are accustomed to, worked surprisingly well. Some 87 percent of the patients whose insomnia was resolved in four treatment sessions also had their depression symptoms disappear, almost twice the rate of those whose insomnia was not cured.
