Fifteen children (most of whom were neurologically multiply disabled)
with severe, chronic sleep disorders were treated with 2 to 10mg of or
al meratonin, given at bedtime. Nine had fragmented sleep patterns, th
ree had delayed sleep onset and three others had non-specific sleep di
sturbance of unclear aetiology; all had failed to respond to conventio
nal management. Nine patients had ocular or cortical visual impairment
. The health, behavioural and social benefits of treatment were signif
icant, and there were no adverse side-effects. While the response was
not always complete, the study clearly showed that melatonin has an im
portant role in the treatment of certain types of chronic sleep disord
ers.
