[Sleep disorders related to anxiety].
Sleep disorders related to depressive illness are now well documented. However, sleep disturbances associated with anxiety have only been explored in recent time. All types of anxiety (generalized anxiety, obsessive-compulsive disorders, panic attack) are associated with sleep disorders such as early insomnia, sleep interruption and low efficiency of sleep. The EEG approach gives different results according to the type of anxiety. Generalized anxiety is associated with total sleep time reduction and low efficiency of sleep. Sleep is unstable with numerous awakenings. Longer periods of stage 1 and 2 sleep are observed and slow wave sleeps as well as REM sleep time is reduced. REM sleep latency may be reduced in obsessive compulsive disorders. Although sleep abnormalities observed in anxiety disorders differ from those observed in depressive disorders, none of these features can be considered specific of anxiety.
