Confusion On Awakening Called New Sleep Disorder

A new study suggests a disorder called “sleep drunkenness” may affect one in every seven people.

Sleep drunkenness occurs when, during or following arousals from sleep, peoples are confused or perform inappropriate behavior, such as answering the phone instead of turning off the alarm. The episodes occur either during the first part of the night or in the morning.

An episode, often triggered by a forced awakening, may even cause violent behavior during sleep or amnesia of the episode.

“These episodes of waking up confused have received considerably less attention than sleepwalking even though the consequences can be just as serious,” said study author Maurice M. Ohayon, M.D., D.Sc., Ph.D., with Stanford University School of Medicine.

For the study, 19,136 people age 18 and older from the general U.S. population were interviewed about their sleep habits and whether they had experienced any symptoms of the disorder. Participants were also asked about mental illness diagnoses and any medications they took.

The study found that 15 percent of the group had experienced an episode in the last year, with more than half reporting more than one episode per week.

In the majority of cases — 84 percent — people with sleep drunkenness also had a sleep disorder, a mental health disorder, or were taking psychotropic drugs such as antidepressants.

Less than one percent of the people with sleep drunkenness had no known cause or related condition.

Among those who had an episode, 37.4 percent also had a mental disorder. People with depression, bipolar disorder, alcoholism, panic or post-traumatic stress disorder, and anxiety were more likely to experience sleep drunkenness.

The research also found that about 31 percent of people with sleep drunkenness were taking psychotropic medications such as antidepressants.

Both long and short sleep times were associated with the sleep disorder. About 20 percent of those getting less than six hours of sleep per night and 15 percent of those getting at least nine hours experienced sleep drunkenness.

People with sleep apnea also were more likely to have the disorder.

“These episodes of confused awakening have not gotten much attention, but given that they occur at a high rate in the general population, more research should be done on when they occur and whether they can be treated,” said Ohayon.

“People with sleep disorders or mental health issues should also be aware that they may be at greater risk of these episodes.”
