Narcolepsy often begins in childhood but is infrequently recognized, partly because of its many manifestations that can be confused with other conditions. The clinical presentations of excessive sleepiness, cataplexy, hallucinatory phenomena, and sleep paralysis (not always occurring together) are very varied. The picture may be further complicated by the occurrence of automatic behaviour, memory and visual problems, and associated sleep disorders, as well as the psychological and social consequences of having narcolepsy. Not surprisingly, therefore, misinterpretation of the symptoms as primarily psychological, or otherwise physical, may well occur leading to inappropriate management including initial referral to psychiatric or educational rather than neurological or sleep disorder services. The wide-ranging and special features of childhood narcolepsy need to be appreciated by health care and other professionals as well as by parents.
