Paradoxical Insomnia Paradoxical insomnia, also called sleep state misperception, is a rare sleep disorder. Unlike insomnia, where a person has difficulty falling and staying asleep, paradoxical insomnia causes a person to experience a distortion in perception that makes them believe that they are up all night when they are actually sleeping. A person with paradoxical insomnia has intense awareness throughout the night; they feel everything is louder and brighter. It is these feelings that give them the perception that they are not sleeping, when in fact they are. They may complain of insomnia, but they experience little daytime fatigue or other complications of true insomnia. Sleep State Misperception Causes and Treatment Researchers are not clear about the cause of sleep state misperception, although they say it may be related in some way to sleep apnea. They have determined that the disorder is more common in women than men and that it develops mostly in those who are younger or middle-aged. People with paradoxical insomnia also tend to have faster metabolic rates according to one research study. Treatment for paradoxical insomnia may involve wearing a CPAP mask. Avoiding heavy meals with lots of carbohydrates and sugars may also help since these raise the metabolic rates and a lower metabolic rate may reduce symptoms. If you are concerned that you or a loved one may have paradoxical insomnia, consult with your doctor or visit a sleep center for professional diagnosis and treatment.
