Objectives: Parents of children with opsoclonus-myoclonus syndrome (OMS) frequently describe poor sleep and rage attacks. We hypothesized that these manifestations are related and could result from underlying monoaminergic dysfunction. Study design: We clinically characterized the sleep and behavioral characteristics of 51 young children with OMS; 19 of those with the most disruptive sleep patterns were treated with trazodone, a soporific serotonergic agent. Results: Sleep disturbances, including prolonged sleep latency, fragmented sleep, reduced quantity of sleep, snoring, and nonrestorative sleep, were reported in 32 children, and frequent rage attacks were reported in 25. In 59% of the poor sleepers, parents felt that the problem was severe enough to warrant treatment. Children sleeping < 10 hours/night had a higher rage frequency than those who slept more. Of the children who required trazodone, 84% were receiving corticosteroids or adrenocorticotropic hormone (corticotrophin), compared with 37% in the subgroup with normal sleep. Trazodone (3.0 ± 0.4 mg/kg/day) improved sleep and behavior in 95% of the children, significantly increasing total sleep time by 72% , decreasing the number of awakenings by 76% , and reducing rage attacks by 33% . Conclusions: Children with OMS exhibited multiple types of sleep disturbances, which contributed to rage attacks. Trazodone was effective in improving sleep and decreasing rage attacks and was well tolerated, even in toddlers.
