[Use of antidepressants in sleep disorders: practical considerations].
There is a general tendency to restrict the notion of sleep disorders to insomnia and consequently to limit treatment to the prescription of hypnotics. However, it is very often of benefit to prescribe psychotropic agents, in particular antidepressants, not only in insomnia but also in certain cases of hypersomnia, parasomnia and dysomnia associated with organic diseases. In some conditions, however, antidepressants may either induce or aggravate sleep disorders. This is the case with a number of psychostimulants that occasionally induce insomnia. It is also true of the tricyclic antidepressants, which may worsen or even induce a restlessleg syndrome that is often associated with periodic movement syndrome. On the other hand, the antidepressants may play a therapeutic role in certain sleep disorders : - depression-related insomnia is of course the << primary >> indication for antidepressants. Furthermore, certain antidepressants exhibit a sedative action resulting in a hypnogenic-type effect which appears well before the antidepressant effect; - the other types of insomnia may also often be treated with antidepressants : not acute reactional insomnia, against which hypnotics are remarkably effective, but chronic insomnia. In addition, all antidepressants may eventually correct depressive hypersomnia, but in these cases, it is evidently preferable to prescribe non-sedative drugs. Although some tricyclic antidepressants have been proposed for use in hypersomnia due to sleep apnea, their therapeutic interest is minor compared with mechanical and surgical treatment. In contrast, antidepressants play an important role in the treatment of narcolepsy, particularly for the correction of attacks of cataplexy. Antidepressants have also been used for some time in the treatment of parasomnia related to slow deep sleep (night terrors and sleepwalking), but the antidepressants may also be used in enuresis and in parasomnia related to REM sleep : nightmares, sleep paralysis, behavioral problems associated with REM sleep. Antidepressant (mainly serotoninergic drugs) are often used in the treatment of fibrolitis syndrome. Finally, antidepressants (particularly the serotoninergic antidepressants) play an important role in the drug treatment of fibromyalgia.
