We performed nocturnal polysomnography on 11 children with autism who had symptoms of disrupted sleep and nocturnal awakenings. We identified rapid eye movement (REM) sleep behavior disorder in 5 of these 11 patients. Since REM sleep behavior disorder typically affects elderly males with neurodegenerative diseases, the identification of this phenomenon in autistic children could have profound implications for our understanding of the neurochemical and neurophysiologic bases of autism. Further, accurate diagnosis of REM sleep behavior disorder would enable specific treatment with clonazepam and help the family and the child consolidate sleep and improve daytime performance.

Stroke in childhood is often catastrophic, with major sequelae. We report the first successful use of recombinant tissue plasminogen activator for arterial stroke in a child. The patient recovered with no neurologic deficit.

Video-EEG monitoring was performed to evaluate 193 children (91 females, 102 males; mean age 9.6 years, SD 5.7) who presented with paroxysmal events of uncertain etiology. Diagnosis of the type of event, i.e. epileptic or non-epileptic, was successfully established in 130 of 193 patients (67.3%). Seventy children (36%) had mental retardation* (MR). Children with MR were more likely (p<0.05) than children without MR to have events during the studies. Children with and without MR had strikingly similar frequencies of epileptic and non-epileptic events. In participants who had events recorded and characterized, epileptic seizures were identified in 67 children (51.5%), non-epileptic events in 54 children (41.5%), and both epileptic and non-epileptic events in nine children (7%). Improved diagnosis prompted appropriate management. This should encourage more frequent use of video-EEG in children, especially in those with MR, to differentiate epilepsy from behavioral disturbances so that specific treatment can be provided.

Video‐EEG monitoring was performed to evaluate 193 children (91 females, 102 males; mean age 9.6 years, SD 5.7) who presented with paroxysmal events of uncertain etiology.
