[Epilepsy beginning in the neonatal period and early infancy].

INTRODUCTION

In this study we analyse several epileptic syndromes that begin in the neonatal period or early infancy, up to two years of age, and we also define their clinical, neurophysiological and progressive aspects as well as their differential diagnoses. Both neonatal and febrile convulsions are excluded.

DEVELOPMENT: The different syndromes are classified according to the predominant type of seizures, which is the one that identifies them, although it is not the only type of seizure presented. In line with this reasoning, the syndromes were divided into four main groups: 1. Epileptic spasms: infantile spasms (West's syndrome), periodic spasms as described by Gobbi and bouts of epileptic seizures without hypsarrhythmia. 2. Tonic seizures: Lennox-Gastaut syndrome. 3. Myoclonias: benign myoclonic epilepsy in infancy, Dravet's severe myoclonic epilepsy, myoclonic-astatic epilepsy and a myoclonic state in non-progressive encephalopathies; and 4. Partial seizures: non-idiopathic location-related epilepsies, malign epilepsy with migratory partial seizures and benign infantile familial and non-familial seizures.

CONCLUSIONS

Thus, it will be possible to establish a plan of studies, differential diagnoses and a rational therapeutic approach depending on the clinical manifestations, while at the same even enabling us to distinguish between the idiopathic, cryptogenic and symptomatic forms.
