EEG data classify ‘autism’ into two distinct groups

The Diagnostic and Statistical Manual, 5th edition (DSM-5) established a single diagnosis of autism spectrum disorder (ASD) that includes Asperger’s syndrome, formerly considered a separate condition. The change was meant to eliminate diagnostic ambiguities, but it has encouraged schools to take a “one size fits all” approach, putting all children with autistic features in the…

The genetics of early-onset psychosis: Could it aid understanding of schizophrenia?

At age six, Matthew (not his real name) began hearing voices coming out of the walls and the school intercom, telling him to hurt himself and others. He saw ghosts, aliens in trees and color footprints. Joseph Gonzalez-Heydrich, MD, a psychiatrist at Boston Children’s Hospital, put Matthew, at age 9, on antipsychotic medications, and the…

Autism and Asperger’s are different… at least on EEG

Is it Asperger’s syndrome or is it autism? Since there are no objective diagnostic measures, the diagnosis is often rather squishy, based on how individual clinicians interpret a child’s behavior. According to the Diagnostic and Statistical Manual, fourth edition (DSM-IV), early problems with language development are an indicator of autism; if there are behavioral symptoms…

The physics of autism

People sometimes say that children with autism “march to a different drummer” or “vibrate at a different frequency.” New research analyzing electrical activity in the brain—via electroencephalography, or EEGs—makes it tempting to speculate that these clichés have some truth to them. EEGs have been around for close to 100 years, and are relatively cheap. But…

Brain ‘connectome’ on EEG could help diagnose attentional disorders

Attention deficit disorder (ADD), with or without hyperactivity, affects up to 5 percent of the population, according to the DSM-5. It can be difficult to diagnose behaviorally, and coexisting conditions like autism spectrum disorder or mood disorders can mask it. While recent MRI studies have indicated differences in the brains of people with ADD, the differences are…

Steroids for regressive autism?

In as many as a third of cases of autism spectrum disorder (ASD), children’s language and social skills develop normally at first. Then, between 1 and 2 ½ years of age, they begin to regress, losing words and retreating from interactions with parents—often abruptly. There has been some anecdotal evidence that steroid treatment can help…
