Childhood migraine and somnambulism

Based on a sample of 222 children from four diagnostic groups, a high frequency of somnambulism in children suffering from migraine headache is reported. The strength of the association between somnambulism and childhood migraine raises the possibility that somnambulism might be considered as a minor diagnostic criterion in the clinical diagnosis of childhood migraine. This association may further clarify the nature of the serotonin abnormality underlying migraine.
