Epilepsy and epileptiform EEG: association with autism and language disorders.

The relationship between epilepsy, language, behavior, and cognition is not well understood. Developmental and acquired disabilities such as autistic spectrum disorders, Landau-Kleffner Syndrome, electrical status epilepticus in sleep, and developmental dysphasias have been associated with epileptiform abnormalities. These disorders share many common features and raise important questions regarding this intricate relationship. This article reviews these disorders and discusses the proposed interaction between epileptiform abnormalities and cognitive dysfunction. Diagnostic and treatment issues will also be reviewed.

Treatment of seizure disorders and EEG abnormalities in children with autism spectrum disorders.

The treatment of seizure disorders EEG epileptiform abnormalities without epilepsy in children with autism spectrum disorders (ASD) is considered within the context of the relationship of epilepsy and epileptiform disorders to language, behavior, and cognition. There is an increased prevalence of both epilepsy and abnormal potentially epileptogenic activity in children with ASD. Anecdotal evidence suggests that the use of anticonvulsants to treat epileptiform discharges thought to be producing dysfunction in selected aspects of cognition, language, or behavior makes a positive difference in a subgroup of children with ASD, but there is inadequate evidence on which to base specific recommendations. There is, at present, no scientific justification for considering epilepsy surgery in children with ASD in the absence of intractable clinical seizures.

Social and nonsocial factors in the Childhood Autism Rating Scale.

The Childhood Autism Rating Scale (CARS) was factor analyzed to determine if distinct and independent "subgroups" of symptoms could be derived, which would be consistent with the current multidimensional theory and nosology for autism. To address this issue, the CARS was factor analyzed for a sample of 90 children with diagnoses of either autism or PDDNOS, based on DSM-III-R diagnostic criteria. Five factors emerged: Social Communication, Emotional Reactivity, Social Orienting, Cognitive and Behavioral Consistency, and Odd Sensory Exploration. Factor-based scales were created. These factor-based scales were demonstrated to distinguish subjects with autism from subjects with PDDNOS and nonautistic subjects. Factor-based scores were examined to determine the degree to which they were associated with individual differences (such as age, IQ, gender, history of regression, and history of abnormal EEGs) among children with pervasive developmental disorders (PDDs). The application of these distinct and independent factors may have important clinical and research implications. The generation of factor-based scales may provide information on the nature of the individual differences that are thought to be present among children with autism. Additionally, the use of factor-based scale scores may increase the sensitivity of the CARS for identifying younger and/or higher functioning individuals within the PDD spectrum.

Longitudinal examination of the behavioral, language, and social changes in a population of adolescents and young adults with autistic disorder.

This follow-up study evaluates the behavioral, language, and social outcomes in a population of autistic patients initially examined in childhood. We evaluated 102 (63%) of the 163 eligible subjects, including 54 adolescents (12-17 years of age) and 45 adults (> or = 18 years of age). Three patients had died in the interim. Behavior difficulties continued to be a problem in 69% of adolescents and adults. Thirty-five percent of adolescents and 49% of adults engaged in self-injurious behavior, and slightly more than 50% of adolescents and adults exhibited some stereotypic behaviors. Over 90% of both adolescents and adults had persisting social deficits. Language improved with age, although only 35% achieved normal or near-normal fluency. Comprehension also improved, although only 29% of subjects had achieved normal or near-normal comprehension of oral language. At the time of last follow-up, 28% of all patients and 53% of adults were living in residential placement. Only 11% of adults were employed on the open market, all in menial jobs; an additional 16% were employed in sheltered workshops. The social, behavioral, and language deficits identified in early life in autistic children tend to persist into adolescence and young adulthood.
