Rhythmic movement disorder is one of the sleep–wake transition disorders listed in the International Classification of Sleep Disorders. According to this classification, the condition commonly occurs in infants and toddlers, and persistence beyond 4 years of age is unusual. Recently, we encountered a case in which rhythmic movement disorder persisted up until the age of 12 years with spikes registering on the sleep electroencephalogram. Epileptic seizure was ruled out because of the characteristic rolling movement, absence of any other epileptic symptoms (e.g. vocalization and tonic‐clonic seizure) and cessation as a result of removal of the blanket.
