Sleep Hygiene, Insomnia and Mental Health
What psychiatric/mental health conditions involve insomnia?
Substance abuse, mood, anxiety, and psychotic disorders are a few of the many conditions that involve insomnia. It is unknown why insomnia is such a common symptom among these illnesses.
Why is it important for a person with mental health problems to treat their insomnia?
Insomnia may not only be a symptom of some psychiatric diseases, it may also contribute to these disorders. Depending on the person, it may be important to get targeted treatment for insomnia, especially when the treatment of the primary disorder(s) does not improve the patient's sleep.
Does insomnia lead to these conditions or is it only a symptom?
If you asked this question 20 years ago, the answer would have been "insomnia is a symptom." Over the years, this perspective has changed. It is now recognized that insomnia may occur and not be associated with acute psychiatric or medical illness. This is called Primary Insomnia (or Psychophysiologic Insomnia). The question now is whether such a disorder represents a risk factor for, or a sign of, psychiatric and/or medical illness. While the jury is out regarding insomnia and medical illness, the evidence with respect to psychiatric illness is clear and compelling. Patients with persistent and untreated insomnia are at between 2 and 10 times the risk for new onset or recurrent episodes of major depression. There is also good evidence that insomnia is a risk factor for the development and/or recurrence of anxiety disorders and substance abuse.
If a person is experiencing insomnia, what should he or she do about it?
If the insomnia is acute (less than approximately 14 days), there are two viable options. First, do nothing. If one does not compensate for sleep loss (does not go to bed earlier, get out of bed later, stay in bed waiting for sleep, nap, etc.), it is likely that "the ship will right itself". When adopting this strategy (the "tough-it-out" approach), the one thing you can do is judiciously use caffeine to maintain daytime function. Second, visit your doctor, who may prescribe a sedative.
At what point should someone seek out treatment?
While it is unknown precisely when acute insomnia becomes chronic, a good rule of thumb would be two to four weeks. The bottom line is: getting treatment earlier rather than later can only be a good thing. There will be less personal suffering. It may also be true that the disorder is easier to treat when it is dealt with early and that early treatment may reduce your risk for the development of other disorders.
