We present the clinical and EEG evolution of four patients with ring chromosome 20 syndrome. All paztients had epilepsy since childhood, with non-convulsive status epilepticus (NCSE) and partial seizures with or without secondary generalization. EEG shows epileptic abnormalities predominantly on the frontal regions. In our cases, epilepsy improved during the years, in particular NCSE episodes tended to disappear and partial seizures tended to decrease. The mental impairment and dysmorphic features appear to correlate with the degree of ring 20 mosaicism. No correlation was found between the degree of mosaicism and the severity of epilepsy and its evolution over years.
