The majority of those who’d experienced confusional arousal were experiencing it regularly.
53.8 percent reported having at least one episode per week , and 24.7 percent reported two to five episodes per month.
For 37.6 percent of sufferers, the episodes were brief – less than 5 minutes. But 30.1 percent of them said the episodes could last 15 minutes or more after waking up.
Many shared similar symptoms. 57 percent reported being disoriented as they woke up, and 34.4 percent said they had difficulty talking or thinking clearly. In addition, 19.9 percent said they experienced “inappropriate behaviors” such as grabbing the phone instead of flailing for the alarm clock.
Confusional arousal isn’t officially classified as a disorder, the researchers pointed out, “probably because it has received little attention from the scientific community.”
But if it was, they said, it could raise awareness. And that could lead to a better understanding of the condition and better treatment options.
“Our study shows that underestimating the importance of CA leads to a misunderstanding of the disorder and its effects,” the study authors wrote.
