INTRODUCTION: Seventeen girls diagnosed as Rett syndrome (RS) patients suffer or have suffered epileptic fits; we have analyzed the evolution of these seizures. The RS diagnosis is based on criteria established by the Rett Syndrome Diagnostic Criteria Working Group in 1988.
PATIENTS AND METHODS: All girls have had clinical, biochemical, electroneurophysiological neuroimaging and cytogenetic studies done on them. Periodic EEG were carried out while the girls were awake; all had night-time EEGs done. The females are aged between 7 y 5 m, and 22 y 7 m (medium 14 years, 8 months). The age at first seizure was between 18 m and 7 y 8 m (median 4 years 5 months).
RESULTS: The clinic semiology is in decreasing order: tonic, generalized clonic, partial, absence and myoclonic seizures; eight patients have had more than one type of seizures. The frequency is variable: one or more continuous seizures in 6 cases, sporadic seizures in 3 cases, series of seizures in 4 cases, and subnitrant seizures in 4 cases. The evolution is variable: 6 cases have presented only the first fit, and 11 cases recurrent seizures which in 5 have ceased between 8 and 9 years, and 1 case at 13 years.
CONCLUSIONS: The study shows that the epileptic seizures in RS present three evolution profiles: 1. One or more non recurrent seizures (35.3%); 2. Recurrent seizures until 8-9 years (35.3%); 3. Recurrent seizures in subnitrant form which continued after puberty (29.4%).
