Abstract
Multiple studies have started the greater risk of autistic population of suffering epileptic seizures. The association of epilepsy and autism can consider between 7-42 percent. In autism, epilepsy has two tips of frequency, during the first three years of life and in the puberty; girls present more epilepsy than boys do.
Diverse types of seizures have been described: partial complex, infantile spasms, atonics, mioclonics, atypical absences and generalized tonic-clonic seizures. The epileptiforme activity is located predominantly in temporal, central, frontal and occipitals areas. Studies with magneto encephalography in autism have emphasized a high prevalence of subclinical epileptiforme activity in 82-92 percent of patients; nevertheless all patients present unusual behaviors that can consider as subclinical crisis. The epileptiforme activity in the perisylvian area predominates in the left hemisphere, fact that would explain the lack of acquisition of cognitive, communicative, and social aspects of behavior
