The importance of seizure-inducing factors in youth.
Of over forty known epileptogenic mechanisms, some eight involve transient conditions, the regulation of which necessarily involves the understanding cooperation of the patient/parents. Tension states, alterations of the wake-sleep cycle, fatigue and sleep deprivation, CNS stimulation by sensory or drug means, and shifts of the water and acid-base balances constitute the bulk of such seizure-inducing factors. The relative lack of CNS homeostatic control, due to immature development of the blood-brain barrier and cerebral maturation, serve to exaggerate these problems in childhood. In a referred group of 150 refractory epileptic children, the seizure-inducing mechanisms were found to be important (50% reduction of seizure incidence) in 20% and to be of "crucial" importance (complete control) in an additional 14%. These results indicate the importance of such mechanisms in selected children with epilepsy, who were only marginally or inadequately controlled by drug therapy. Reviews of the literature have suggested that this more comprehensive approach to the therapeutic management of epilepsy has not been adequately exploited.
