Insights
Confusional arousal (CoA), a sleep disorder, can be misdiagnosed as epilepsy. Treating obstructive sleep apnea (OSA) resolved the patient's nocturnal events, highlighting OSA as a treatable cause of CoA.
Area of Science:
- Neurology
- Sleep Medicine
- Pediatrics
Background:
- Epilepsy is often considered in children with nocturnal events, but parasomnias can present atypically.
- Confusional arousal (CoA) is a parasomnia characterized by confusion and disorientation upon waking.
- Obstructive sleep apnea (OSA) is a common sleep disorder that can have varied clinical manifestations.
Observation:
- A 10-year-old female with persistent nocturnal events despite epilepsy treatment was evaluated.
- Video polysomnography (PSG) captured typical events during sleep.
- The patient exhibited confusion and nonsensical speech during nocturnal awakenings.
Findings:
- The patient was diagnosed with confusional arousal (CoA) secondary to obstructive sleep apnea (OSA).
- Nocturnal events resolved completely after successful treatment of OSA.
- This case underscores an atypical presentation of CoA mimicking seizures.
Implications:
- Obstructive sleep apnea (OSA) should be considered as a potential treatable cause of confusional arousal (CoA).
- Video-PSG is crucial for diagnosing CoA and differentiating it from epilepsy.
- Early diagnosis and treatment of OSA can resolve CoA symptoms in pediatric patients.
Abstract:
A 10-year-old female presented to the sleep clinic for a second opinion about her epilepsy diagnosis. She had been treated with antiepileptic medication but her events persisted. The child would wake up several times every night speaking nonsense words, appear confused to her family, and then go back to sleep. A video of the polysomnography (PSG) showed the patient having two of her typical events. The patient was eventually diagnosed with confusional arousal (CoA) secondary to obstructive sleep apnea (OSA). The nocturnal events resolved after her OSA was treated. This case highlights an atypical clinical presentation for a type of parasomnia like CoA that was misdiagnosed and treated for seizures. It will illustrate OSA and its mechanisms as a potential occasional treatable cause for CoA. It also demonstrates the importance of video-PSG in the work-up of CoA.
