“…14 However, the incidence of epilepsy in individuals N-SMR (33.7%) was very similar (31%) as described by Morre. 13 In our research, the occurrence of interictal paroxysmal activity in DS (22.1%) was resembles to report by Seppäläinen and Kivalo. 14 The prevalence of reflex epilepsy appears to be higher in patients with DS than individuals with other forms of mental disability and the mentally healthy general population.…”

“…14 analyzed the electrographic patterns in a large group of patients with SD (8.7% with epilepsy), found electrographic abnormalities in only 12% of cases and interictal paroxysmal activity in 21%. In our patients with DS, the incidence of epilepsy (27.9%) was significantly higher thanto describe by Morre (5.2%) 13 and Seppäläinen and Kivalo (8.7%). 14 However, the incidence of epilepsy in individuals N-SMR (33.7%) was very similar (31%) as described by Morre.…”

INTRODUCTION: Down syndrome (DS) is the most common chromosomal abnormality causing mental retardation and its association with epilepsy is highly variable in childhood. Although the first descriptions of the syndrome did not report seizures, their association with epilepsy is relatively common. METHODS: were evaluated 68 individuals with DS and 83 with non-syndromic mental retardation (N-SMR). All patients underwent digital EEG, lasting at least 30 minutes and electrodes positioned according to the International 10-20 System of Electrode Placement. Data were analyzed using descriptive statistics and proportions were compared with Student's t-test and test of Differences between Proportions with p<0.05 considered statistically significant. RESULTS: DS: 27.9% had epilepsy (first seizure with 2.2±3.7 years). Fifteen (22.1%) patients had epileptiform discharges, 5 (7.4%) hypsarrhythmia, 5 (7.4%) focal pattern, 3 (4.4%) generalized pattern and 2 (2.9%) multifocal pattern. N-SMR: 33.7% patients had epilepsy (first seizure with 1.2±4.5 years). Twenty-three (27.7%) patients had epileptiform discharges, 10 (12.0%) focal pattern, 5 (6.0%) generalized pattern and 8 (9.6%) multifocal pattern. CONCLUSION: The difference between the occurrence of epilepsy in DS and N-SMR was not statistically significant, as well as between normal EEG, EEGs with focal pattern, generalized pattern and multifocal pattern. In SD group 7.4% have shown hypsarrhythmia.The comparison with N-SMR was not possible because none of these has shown this EEG abnormality.
