A group of 36 epileptic patients is studied; in 35 the drug was suppressed and in 1 the treatment was not started. The group was compared with epilepsy in general regarding to the age of onset, the time of the disease, the frequency of the seizures, the clinical manifestations and the EEG pattern. In view of the results attained by the investigation the author draws the following conclusions: 1) in the group studied the onset of the disease prevailed at the second decade of life; 2) the disease duration was lower than 1 year in 55% of the cases; 3) the cases submitted to early treatment predominate in the group studied; 4) the patients with pure convulsive seizures predominate when compared to those with focal convulsive fits; significant differences were not found when the EEG patern of the group studied was compared with epilepsy in general; the rate of normal EEG was similar in both groups.
