Estimates are that sleep drunkenness affects about 1 in 7 Americans. After reviewing the sleeping habits of more than 19,000 adults, the study on sleep drunkenness led by Dr. Maurice Ohayon, found that 84% of CAs were associated with a sleep disorder (70.8%) (most often dyssomnia and parasomnia) or a mental health disorder (37.4%), including depression, bipolar disorder, alcoholism, panic or post-traumatic stress disorder, and anxiety. Of the 19,000 adult participants in the Sleep Drunkenness study:
- Less than 1% didn't have another sleep problem
- Those with sleep apnea were more likely to experience confusional arousal.
- 20% of those who slept less than 6 hours a night and 15% of those who slept at least 9 hours, suffered from sleep drunkenness
- Most adults reporting confusional arousal were not receiving medication, but among those who were, antidepressants were most common.
