Typically, this type of seizure lasts between 10 and 30 seconds. The person, most often a child aged 5 to 15, abruptly stops whatever he's doing (talking, walking) and appears to "stare into space." Absence seizures rarely cause a true convulsion in which the person falls down or collapses. Despite briefly losing consciousness, the person recovers fully with no lingering confusion or other ill effects.
The overall prevalence of seizures is 3.6 per 1000 according to epidemiological studies on the prevalence of epilepsy. The ratio is 3.83% and 3.45% in male and female respectively. There is no significant difference observed in the prevalence of epilepsy on the basis of location.
