Symptoms: Altered social interaction, communication (both verbal and nonverbal) and restricted and repetitive behavior.
Parents of children with ADS know this is a complex disorder that has varying levels of strengths and impairments as well as varying associated disorders. Functional eeg can help sort out these complexities and assess the degree to which they affect behavior.
Studies have found that EEG predicted ASD with high sensitivity and specificity — exceeding 95% at some ages. EEG measurements also accurately predicted the severity of ASD symptoms.
“Autism Spectrum Disorder (ASD) often presents a treatment challenge due to the variety of symptoms that make each case unique. Medication prescribed to manage ASD associated symptoms such as anxiety, depression, attention issues, and behavioral problems often fail to alleviate symptoms and can produce undesirable side effects. This medication failure could be related to the increased prevalence of isolated epileptiform discharges (IEDs) in psychiatric patients, that go undetected without the use of an electroencephalogram (EEG).” Dr. Ron Swatzyna studied 140 nonepileptic patients with ASD under the age of 25. Of the 140 patients, 36.4% were found to have IEDs after an EEG screening. The results show that compared to a healthy population, many patients with ASD have IEDs despite never having a seizure. These findings support the use of EEG in patients with ASD, to allow for more individualized and precise medication selection.
