Role of Standard EEG in Management of Autism

Autism spectrum disorders (ASD) are heterogeneous neuro-developmental disorders involving multiple neural system dysfunctions with neuropsychological manifestations. ASD are characterized by cognitive and social and communication impairments, and by restricted and stereotyped behaviors. ASD are supposed to be accompanied by abnormal neural connectivity. EEG can be used at various ages and developmental disabilities to study brain physiology, has a higher tolerance for movement, and more available. It can be used to repeated utility because it is non-invasive. Considering the role of the EEG in patients with autism, more articles exist on signal EEG, computerizedanalyzed EEG, EEG power, Quantitative EEG; few articles about standard EEG exist. Standard EEG is an available test and real-time physiological study can play an important role in the assessment and management of the epileptic and non-epileptic autistic patients. Therefore, analysis of these findings is important, the proper EEG interpretation helps us to differentiate the closest diagnosis, in the autistic patient with clinical or subclinical seizures and in terms of critical such as autistic regression. Quantitative EEG sounds of good perspective as an approach for monitoring treatment outcomes. Rates of inter-ictal epileptiform discharges varied as 6% to 30% of ASD patients. Recently, even higher rates of epileptiform discharges have been reported. Seizure waves cause cerebral dysfunction. Furthermore, cognitive function correlateswith inter-ictal epileptic discharges. Even in the absence of clinical seizures patients with obvious abnormal EEG may improve behavior and intellect after treatment.One of the best-known associations with brain dysfunction is the high risk of epilepsy in ASD. Epilepsy is commonly reported to occur in 1/3 of individuals with ASD. However, the exact prevalence remains unknown and the literature presents a wide range of estimates from 5% to 46%. ASD is also increased in epilepsy populations, with as high as 32% meeting diagnostic criteria
