Prognosis of childhood seizure disorders: present and future.
The prognoses for seizure disorders have been examined since the beginnings of epileptology, and only recently has the realization emerged that, ultimately, prognosis depends on causation, which, in turn, determines whether a condition is self-limited or progressive. This factor is more important than either mode or alacrity of therapeutic intervention. The epilepsies are a series of conditions that have the final common path of either increasing cerebral irritability or synchronizing normally occurring electrical activity in such a manner that seizures result. In turn, some seizure disorders are characterized by secondary changes in neuronal synaptogenesis, leading to the development of circuits of predilection, which then render the process autonomous. Epileptogenesis has then become epilepsy, which is the norm in acquired rather than genetic epileptogenesis. An understanding of the basic differences between the primary (idiopathic) epilepsies and the secondary (acquired or symptomatic) epilepsies is basic to a discussion concerning prognosis and to the development of a definitive individualized treatment plan. An elucidation of the genetic factors in idiopathic epilepsy and their neurochemical consequences represents a major frontier in epileptology.
