[Enuresis: clinico-epidemiologic study. Preliminary communication: its relation to essential headache].

Sleep disturbances being considered as a risk factor for headache and the enuretic episode being defined, preliminary data are reported on a clinical epidemiological survey into the greater risk that headache enuresis represents for women despite the fact that the phenomenon is more common among men. Finally it is hypothesised that there is only one qualitative and/or quantitative pathogenetic mechanism that may be transmitter type, or in the light of recent studies, receptorial.
