While this article might look like it’s about insomnia, it’s the first in a 3-part series about treating bipolar disorder with as few medications as possible. Cognitive behavioral therapy for insomnia (CBT-I) is a major ingredient in a new psychotherapy for bipolar disorder; indeed, the latter is called CBT-IB, a bipolar-specific variant of CBT-I.
To be prepared to offer CBT-IB, you’ll need to be familiar with plain CBT-I, where the good news is (as shown herein), a remarkable free app can help you provide research-grade therapy with little additional reading or practice. Once you’re familiar with CBT-I, look for the next article in this series, on the important bipolar extension of this technique.
Surely you feel the pressure to reduce the use of benzodiazepines for sleep, because of their linkage with opiates and mortality risk.1,2 Sedative/hypnotics (“z-drugs” such as zolpidem and its cousins) also are associated with an increased risk of falls3 and other hazards.4
But simply offering patients a list of “sleep hygiene” recommendations is not likely to meet the needs of many patients. Some of them will view it with scorn, thinking it shows you really don’t understand the severity of their insomnia.
Fortunately, a new smartphone app helps you offer much more than just sleep hygiene. With relatively minimal reading and practice, you can offer a comprehensive psychotherapy for insomnia: CBT-I.
Two more ingredients make a therapy
Now add typical CBT: cognitive techniques include eliciting the typical thoughts your patient will have while lying awake (“I will feel terrible tomorrow,” “If I don’t sleep, I can’t work,” etc), then exploring alternative thoughts and experiments to test them. Behavioral techniques include breathing training, simple meditations (eg, this free collection from the UCLA Mindfulness Research Center), and paradoxical intention (remaining passively awake).
The final ingredient in CBT-I is the most challenging for both patient and therapist: sleep restriction therapy. It relies on the second drive to sleep, in addition to circadian rhythm: progressive sleep deficit (aka, homeostatic drive). Simply put: the longer one goes without sleep, the greater the pressure to do so, although genetic and environmental factors are also involved (here’s a detailed review of this 2-process model).
In sleep restriction therapy, patients with insomnia are invited to estimate the amount of sleep they’re actually getting. They are then allowed to spend only that amount of time in bed (with no naps). When the resulting additional sleep deficit improves their sleep efficiency (time asleep relative to time in bed) to 90% or more, they are then allowed to add additional time in bed, as long as their improved sleep efficiency is maintained.
Now that’s got teeth, doesn’t it? Unless CBT-I was more effective than pills, who would want to go through that?
